Studio V2.13 Part III Update NOTES This disk does update Studio V2.12 and older. This Part III is only of use to Epson ESC/P2 compatible printer users. Ask for the update disk Part II if you own a Canon printer. Ask for the update disk Part I if you don't own a printer type mentioned above. So Deskjet and Laserjet users should ask for Part I. Note: You do need your original Studio disks for installing this software. What's new? This Part III update disk mainly offers improved Epson Stylus Color software. Most of the work done affects the Studio printing program. Many new Stylus Color (II, Pro,...) profiles have been added. These new profiles offer much better color adjustment than the old ones. As a result, you'll get MUCH better output quality with the printing program. Various Stylus Color output modules are installed by this update. These new output modules are specificly written for the Epson Stylus family printers. They offer features like TIFF/Delta compression for faster output, control over the printers dot size, IO buffering and more. A new "SetupStylus" program was created to finaly help you calibrating and setting up your Stylus printer. The program adjust the printers mechanics for better output. SetupStylus also allows editing the printers permanent settings. This removes the pain of using the printers crypted panel for a controlling the printers features. So, start installing and have a look at the additional documentation below and try the SetupStylus software. ****** Here is the list of the latest Studio distributors: Germany: Australia & New Zealand arXon GmbH GSoft Australia Pty Ltd.

In the past, people complained about too dark output of Studio. Please note that the gamma value determined using the gamma window of Studio only describes the value for the screen mode used for displaying the gamma window (ie. your Workbench screen mode). This screen mode usualy has a different gamma value than the value used for displaying your image. We will address this problem in one of the next releases. in the meantime: if your output of Studio is too dark even if you are sure all CMS settings are correct for your setup, lower the gamma value in Studio's Monitor window until the output has the correct brightness. Once done, all your prints should be fine in brightness and color hue. ****** EpsonP2 Driver The EpsonP2 Workbench driver densities have changed in order to support the 360*720dpi resolution of the Epson Stylus Color IIS and Stylus 820. Warning: please note that most of the current Epson printers can't print using the 360*720 dpi density - even if they support do 720*720 dpi. So don't select density 4 if you don't have a printer supporting that resolution. EpsonP2 now supports following densities: Density 1: 360*360 (no driver dithering/color adjustment) Density 2: 720*720 (no driver dithering/color adjustment) Density 3: 180*180 Density 4: 360*720 (Use with Stylus Color IIS/Stylus 820 only) Density 5: 360*180 Density 6: 360*360 Density 7: 720*720 EpsonP2Pref now offers presets for the Stylus Color IIS in order to help you setting up the driver for your wanted paper and resolution. Please note that the presets for greyscale printing are for use with the printers black print head. Don't print greyscales using the printers color head. Please note that the Epson Stylus Color IIS is unable to print true black in color images. The print head will generate black by mixturing all three colors (composite black) on the same spot. As a result, the output quality will be lowered and the ink consumption is pretty high. The Epson high resolution 720dpi paper is highly recommended for high quality dumps on the Stylus Color IIS. You are better off paying some extra cents for this paper instead of using cheap xerox paper. This avoids unnecessary test dumps consuming a great amount of the much more expensive printer ink. So don't safe money at the wrong item... This is just a big hint. ****** The SetupStylus Program ======================= The Studio calibration utility is called SetupStylus and is usualy located in the drawer containing EpsonP2Pref. This is usualy your SYS:Prefs drawer. SetupStylus can also be used for setting up your printer. It allows control over settings usualy only enabled using the printers panel. So it's a much more easy to use method of getting your printer running. Following Epson printers are currently supported by the SetupStylus software: Stylus Color Stylus Color II Stylus Color IIs Stylus Pro Stylus Pro XL Stylus 820 ******* WARNING ******* The SetupStylus software was specificly designed for certain printers. NEVER SELECT A PRINTER OTHER THAN THE ONE YOU HAVE CONNECTED. YOU CAN DAMAGE YOUR PRINTER WITH A FAULTY SELECTION. While this is an extremly unlike event, it can't be said too often. Don't even select a printer that is very similar to yours. For instance, it's not correct to select Epson Stylus Color II if an Epson Stylus Color IIS is connected. Starting SetupStylus -------------------- SetupStylus can be started with various Tool Types or Shell arguments: PUBSCREEN: SetupStylus opens a window on the default public screen. You may specify a special public screen by setting the Tool Type "PUBSCREEN=screenname". The screen name is case sensitive. and the SetupStylus program will open its windows on your application's screen. TOPAZ: SetupStylus is font independent. All text is displayed using the system font. If TOPAZ is specified, only the topaz 8 font is used. SAVE: When using this option, SetupStylus will set-up the printer without showing the set-up window first. This is useful for controlling printer settings from batch files. You can enable certain printer settings without user interaction by using the FROM option in combination with SAVE. Settings can be saved from SetupStylus by using the Save As menu item. SetupStylus will automaticly quit after several seconds if your printer is off or not connected. FROM: SetupStylus saves the settings sent to the printer in a file named SetupStylus.prefs, placed in the same drawer as the SetupStylus program. Next time you start SetupStylus, the current printer settings are read from this file and displayed. FROM allows you to specify a different settings file for reading. You can save other settings files than SetupStylus.prefs using the Save As menu item. DEVICE: SetupStylus usually sets up the output device defined in Workbench 2.04 printer preferences. Since Workbench 2.04, nearly any output device can be defined in preferences for printer output. Usually serial.device or parallel.device is used. You may alter the device using the case sensitive DEVICE Tool Type or Shell argument. UNIT: Workbench 2.04 (or higher) Printer preferences programs may enable you to specify a printer port unit to print to. Most of the current multiport cards enable you to specify a port to print to using a unit number (0 = internal port, 1 = external port A, 2 = external port B ...). Using the UNIT tool type or Shell keyword you can define a unit (port) to print to. Using SetupStylus ----------------- After starting SetupStylus successfull, select your wanted printer using the top left gadget. Below the printer gadget, you'll find the calibration actions offered by SetupStylus for your printer. Use them for calibrating your printer. The right side of the window allows setting up your printer. After doing all wanted adjustments, use the "Save to Printer" gadget in order to save the settings to the printer. To make the saved settings active, turn the printer off/on. SetupStylus saves the settings sent to the printer in a file named SetupStylus.prefs, placed in the same drawer as the SetupStylus program. Next time you start SetupStylus, the current printer settings are read from this file and displayed. This method works only so long as SetupStylus is used for all printer setting changes and is not moved to another directory without the SetupStylus.prefs file. In the next sections you'll find some usefull information about the various settings and actions offered by SetupStylus. Calibration with SetupStylus ---------------------------- Bidirectional Alignment: Selecting bi-directional mode in your printer driver causes your printer to print left-toright and right-to-left. Normally your Stylus printer prints from left to right only (unidirectionally). The bidirectional mode lets you print much faster, but usualy there is a quality loss mainly because of mechanical reasons. So bi-directional printing is a way to print fast with a minor quality loss. Although your printer is calibrated at the factory to compensate mechanical alterations, it may become uncalibrated during shipping. You should have to calibrate your printer only once. If you find it necessary to calibrate your printer again however, you can easily use this utility to recalibrate your printer. If you suspect that your printer needs calibration, the easiest way to check is by turning off bi-directional mode and printing your document again. If the output quality improves, you should recalibrate your printer. You should recalibrate your printer if: o Vertical lines in your output appear jagged o Letters appear to be skewed or split o Wavy gaps appear in halftoned images. Aligning Black and Color output: If you have a color printer (such as the Stylus COLOR), it may be necessary to align the Black print head with the Color print head. You should need to do this only once. If you think that your print heads have somehow become misaligned, you can easily realign them with the calibration utility. You should realign your print heads if: o Black output and color output that should line up doesn't. o Unwanted white spaces appear between black and color output. Note that after using the utility, the settings made will not be saved to the printer unless you turn off the printer using the Operate switch. If you turn off the printer by unplugging it or turning it off with a power bar, the settings will not be saved. After you have saved the settings turn off the printer as normal. Setup with SetupStylus ---------------------- Now some special comments for specific printers when used with SetupStylus: ** Epson Stylus Color ** Following settings can only be changed using the printers front panel: Loading Position, I/F Mode, I/F Wait Time. You can run a printer self-test once you changed the settings. The printer will print all settings. In order to do so, turn the printer on while holding down the "Economy/Condensed" button. Than choose a language using the "FONT" button. Confirm the selection by pressing the "ALT" button once. The printer will than print it's settings. ** Epson Stylus Color II ** Following settings can only be changed using the printers front panel: Loading Position, I/F Mode, Software. You can run a printer self-test once you changed the settings. The printer will print all settings. In order to do so, turn the printer on while holding down the "Economy/Condensed" button. Than choose a language using the "ALT" button. Confirm the selection by pressing the "PAUSE" button once. The printer will than print it's settings. ** Epson Stylus Color IIS ** ** Epson Stylus 820 ** Following settings can only be changed using the printers front panel: Loading Position, Pitch, Paper Thickness You can run a printer self-test once you changed the settings. The printer will print all settings. In order to do so, turn the printer on while holding down the "PAUSE" button. Than choose a language using the "ALT" button. Confirm the selection by pressing the "PAUSE" button once. The printer will than print it's settings. Note: the pitch setting shown by the printers self test may be faulty. For instance, the printer may show a pitch of 17.1cps instead of the correct 10cps. The setting shown by setup program is correct. ** Epson Stylus Pro / Pro XL ** Following settings can only be changed using the printers front panel: Loading Position, I/F Mode, I/F Wait Time You can run a printer self-test once you changed the settings. The printer will print all settings. In order to do so, turn the printer on while holding down the "Economy/Condensed" button. Than choose a language using the "FONT" button. Confirm the selection by pressing the "ALT" button once. The printer will than print it's settings. WRONG PRINTER SELECTED? ----------------------- In the unlikely event you ignored all warnings and used SetupStylus with the wrong printer selected: don't panic. So far, nothing will really damage your printer. Turn off the printer by unplugging the power cord instead of using the printers on/off switch. Than turn it on again and setup the printer using the correct printer selection in SetupStylus. In the unlikely event this doesn't help and your printer still doesn't behave right, use the printer panel to change the printer settings to the default values. If nothing helps, all the supported printers do have a specifc combination of panel buttons causing the printer to do a complete factory reset. This will erase the complete settings of the printer and will setup default values again. After this, your printer will work again. However, you have to run the calibration process again. The button combination that must be pressed during power on of the printer is either listed in your printer manual (search for it - it's usualy 3 buttons and well hidden in the manual) or can be asked at the Epson Hotline. ****** STUDIO'S STYLUS OUTPUT MODULES All Epson Stylus printers support the ESC/P2 printer language. But since the release of the Epson Stylus Color, Epson enhanced the language in order to support various new printer features and to increase the print speed. This update adds several new output modules specificly supporting the latest features of the Epson Stylus Color printers. For instance, the Stylus Color II output module does enable/disable the printers micro dot printing feature. The module automaticly disables unwanted printer panel selections. The module also makes use of compression schemes like Delta and TIFF in order to increase the output speed. Here a list of the new modules: Stylus Color: This module can be used with all current Stylus Color printers. By default, it is installed for the Stylus Color, Stylus Pro and Stylus Pro XL. The module does make use of the better compression schemes used by these printers. Following densities are available from the printing program: 1: 180*180 dpi with TIFF compression 2: 360*360 dpi with TIFF compression 3: 720*720 dpi with TIFF compression 4: 180*180 dpi with Delta compression 5: 360*360 dpi with Delta compression 6: 360*360 dpi with Delta compression 7: 720*720 dpi with TIFF compression Stylus Color II: This module should only be used with the Stylus Color II. Don't use it with any other type of printer. Beside offering the same densities and compression schemes as the Stylus Color module, this module does control the printer's micro dot feature and more. The module also changes the printers internal handling of data when printing greyscales images. As a result you can get faster and better greyscales dumps. Stylus Color IIS: This module should only be used with the Stylus Color IIS. Don't use it with any other type of printer. The module does control the printers dot size and offers following densities: 1: 180*180 dpi with TIFF compression 2: 360*360 dpi with TIFF compression 3: 360*720 dpi with TIFF compression 4: 180*180 dpi with Delta compression 5: 360*360 dpi with Delta compression 6: 360*360 dpi with Delta compression 7: 360*720 dpi with TIFF compression Stylus 820: The Stylus 820 is equal to the Stylus Color IIS module. It only supports greyscale printing. ****** STUDIO PRINTING PROGRAM After three years work Studio's V2.10 CMS printing system is finaly done. With release V2.10 we finaly have CMYK support built-in and various precise profiles. The system now basicly allows you to control any color aspect of your printer. We can now concentrate on the rather "simple" things. V2.11 adds an ink limit control function. ****** Beside offering new Stylus software, the Studio (V2.11) printing program update is mainly a speed update. In the worst case, speed of Studio will only increase by roughly 10%. But under certain conditions, Studio can get 10 times faster than it's previous 2.10d version. The speed increase depends on your settings and the image you print. Mainly the IFF ILBM and dither routines offer improved speed. So printing large IFF ILBM images - especialy in landscape mode - can get much faster. The dither routines now skip left/right margins in the output where no primary color (C,M,Y,K,...) is printed. This can dramaticly improve speed depending on the image. In order to do this - and other upcoming optimizations - all dither routines had to be completly rewritten. ****** Studio (V2.11) now offers you to limit the amount of ink/color printed using the former Separation window. The window can be selected with the "Color..." windows using the "Color: Separation, Weights, Usage" gadget. Note: you can only limit the amount of ink with disabled CMS. Otherwise it's the CMS profiles task to limit the amount of ink. When should you use this function? Usualy whenever your output without CMS becomes to muddy/dark because of too much ink being printed. For instance, let's assume you want to print without CMS on a Stylus Color or Canon BJC 610 printer at 720dpi. In this case, limit the amount of ink to 50% per print color. 50% is the smallest amount giving you full ink coverage on these printers. In most cases, you only have to use the gamma slider in the "Color..." window in order to get good results without CMS. As described in the Studio manual, there are special cases where printing without CMS might be wanted. Users wanting to create profiles should first find out the correct ink usage for the printers before printing the color calibration images. Enter the limits into CMSScan afterwoods. The ink limit for your printer can usualy easily be seen when printing the b/w greyscale calibration picture with 100% ink usage. ****** Studio (V2.08) now supports the PNG image format (PNG is pronounced "ping"). The PNG format is intended to provide a portable, legally unencumbered, well-compressed, well-specified standard for lossless bitmapped image files. We hope PNG will soon replace the well known GIF format. Beside offering more features than GIF, PNG also offers a very good lossless compression. We are sure PNG will soon become a well known standard beside JPEG/JFIF format used for lossy compression ****** Studio (V2.09) now supports the PCX image format. This format is very popular on MS DOS PC's. Studio supports 1,2,4,8 and 24 bit PCX files. Studio is also able to print the first image of DCX images. DCX images are mainly generated by fax software. ****** Studio (V2.10) now offers a saturation slider in the "Color..." window. An additional separation window allows you to control the separation used by Studio when printing color images without CMS. ****** The new separation functions offered are used for converting RGB screen colors to CMYK printer colors. Please note that the separation settings are used only if you print a color image without using the CMS. CMS profiles provide their own separation settings as the profiles are made for a specific separation process. Changing the separation process would result in faulty colors in the output. However, you can change the separation function used by the CMS by changing the profile settings using CMSEdit. Studio currently offers five different separation functions: Internal UCR/GCR: Uses the default internal separation. The method is simple: Studio will print a black dot if a cyan, magenta and yellow dot would otherwise be printed at the same place. Custom UCR/GCR: Uses the standard linear UCR and GCR percentage settings defined by the UCR and GCR integer gadgets. The meaning of this setting is very similar to that used by various DTP and image processing programs on the Amiga. Under color removal (UCR) describes the practice of removing quantities (here defined in percentages) of yellow, magenta and cyan from where the black is printing -- literally removing color from under the black. Greyscale component replacement (GCR) removes yellow, magenta and cyan ink from where all three inks print together, and replaces them with black. The black plate carries most of the tone in the reproduction, therefore neutrals (greys) are easier to print. Again, you define the percentage of how much color should be replaced. Custom UCR / Weak GCR: This setting uses the standard linear UCR setting as described above, but with a preset "weak" non linear grey component replacement function (Weak means less black is used). The non linear function results in composite grey being used for bright shades and black is only used for dark shades. This gives you fewer distrurbing black dots in lighter areas of your output. The output will look less grainy. Instead of offering a GCR setting, this method offers a setting for defining the maximum percentage of black being used by the replacement function. Usually a value between 80 and 100 percent gives good results. "Custom UCR / Medium GCR": This setting is similar to Custom UCR / Weak GCR. However, the GCR function will use black for brighter shades. "Custom UCR /Strong GCR": This setting is similar to Custom UCR / Medium GCR. However, the GCR function will use black for bright shades and the increase of black is nearly linear to the amount of composite grey of the processed color. So, when do you need the separation functions? Mainly when not using the CMS or when generating a profile using the tools (CMSScan) described later in an extra chapter. There is no general rule for which type of separation is best. The "Internal UCR/GCR" function is very fast and offers decent quality. The "Custom UCR/GCR" function is mainly offered for compatibility with other programs. The last three non-linear separation functions offer good quality. If your printer offers good ink coverage without bleeding and similar problems, Custom UCR / Weak GCR gives best results. For instance, if you own a normal inkjet printer, Custom UCR / Weak GCR often gives the best results when using coated paper. Plain paper often results in rather worse output as too much color ink is being printed. In those cases Custom UCR / Strong GCR might be better. Simply give it a try and see what you think is best for your printer, paper and dither method. Again note: when generating a CMS profile make sure you select the correct separation function for your set-up. Otherwise all printed calibration pages might be useless because they would have been made with a bad separation function. ****** Studio (V2.10) now includes several output modules for PCL compatible printers (mainly DeskJets and LaserJets). All output modules use Hewlett-Packard's "Printer Command Language" (PCL) in various forms. The installation program will install the proper output module for your printer. However, if you can't find an output module listed for your specific model of printer, choose an output module that matches your printer's emulation. We get many letters asking for output modules for specific printers, even if a generic module is available. In most cases these letters have been unnecessary. For instance, there is not one single drawback if you use a generic PCL 5C output module instead of a specific DeskJet 1200C module. (PS: You can use this module in b/w mode on Laserjet PCL 5 printers too!!!) The PCL 5C module was designed to work with several printers, including the PaintJet 300XL. The differences between the various DeskJet and PCL output modules are minor. Often the output module will offer you settings in the Config window which are already known by the preferences program for the Workbench driver. So if you don't find a specific setting described here, use the index of the Studio manual to learn about the meaning of the setting. First some general notes. Most modern DeskJet printers are able to print 600 dpi maximum in greyscale mode, while the color mode supports only 300 dpi maximum. If you own Studio V2.10 or higher, the program will automatically switch from color to greyscale printing if you choose a density of 600 dpi. When it comes to color printing, the DeskJet 8xx output module is a little different. Please note that a printer like the DeskJet 850C offers 300 dpi color printing similar to the cheaper DeskJet 660C printer. But the DeskJet 850C printer also offers 64 color shades per addressable printer dot, compared to the normal 8 colors. This results in a much better output quality when printing images. So once the DeskJet 8xx output module is selected, the "Density" gadget in Studio will also show you the printable color shades per addressable printer dot. ****** Following additions have been made to the ARexx interface of Studio V2.10 and V2.11: VERSION Returns the version of the Studio ARexx interface. Up to version 2.09 Studio returns 1 in PRTSTUDIO_RESULT. Version 2.10 returns 2. Version 2.11 and higher returns 3. INKLIMIT (GREY|CYAN|MAGENTA|YELLOW|BLACK|TOTAL) INKLIMIT (GREY|CYAN|MAGENTA|YELLOW|BLACK|TOTAL) Value Reads or writes the amount of ink limit used for a specific output color. Values of 0 to 100% are supports for all colors. TOTAL supports 0-400%. The commands require Studio V2.11 or higher. Use the Version command for detecting the Studio version. COLOR GREYSCALE Selects the default output print mode. The previous setting is returned in PRTSTUDIO_RESULT. No error is reported. Note that it is valid to select COLOR even if the image selected is a greyscale one or the printer driver selected doesn't support color. The setting mainly reflects the default preset. Studio will automatically switch to greyscale printing if required. The commands require Studio V2.10 or higher. Use the Version command for detecting the Studio version. SEPARATION SEPARATION 0-4 Sets the type of separation used when printing a color image without using the CMS. The previous setting is returned in PRTSTUDIO_RESULT. If there was an error, RC is set to 10 and PRTSTUDIO_RESULT to "Illegal value". The following values are supported: 0: Use the default internal separation. 1: Use the standard linear UCR and/or GCR settings defined by the UCR and GCR commands. 2: Use the standard linear UCR setting with a preset weak (Weak means less black is used for replacing composite grey.) non linear grey component replacement function. The GCR command can be used for defining the maximum percentage of black ink being used by the replacement function. 3: Use the standard linear UCR setting with a preset medium non linear grey component replacement function. The GCR command can be used for defining the maximum percentage of black ink being used by the replacement function. 4: Use the standard linear UCR setting with a preset strong non linear grey component replacement function. The GCR command can be used for defining the maximum percentage of black ink being used by the replacement function. The Separation command requires Studio V2.10 or higher. Use the Version command for detecting the Studio version. UCR UCR 0-9999 Sets or reads the amount of under color removal (UCR) in percent. The setting is used depending on the type of Separation selected. The previous setting is returned in PRTSTUDIO_RESULT. If there was an error, RC is set to 10 and PRTSTUDIO_RESULT to "Illegal value". The UCR command requires Studio V2.10 or higher. Use the Version command for detecting the Studio version. GCR GCR 0-9999 Sets or reads the type of grey component replacement (GCR) used by the separation function. The meaning of the GCR value mainly depends on the separation function being used. The value either defines the percentage for black generated from a color by the GCR function, or it defines the maximum amount of black ink to be used. The previous setting is returned in PRTSTUDIO_RESULT. If there was an error, RC is set to 10 and PRTSTUDIO_RESULT to "Illegal value". The GCR command requires Studio V2.10 or higher. Use the "Version" command for detecting the Studio version. ****** Studio Prof. History: E = removed bug C = changed I = improvement 27.11.95 V2.10 I-Switched to SAS/C V6.56 compiler. Optimizer now seems to work fine and thus was fully enabled. I-This is the major improvement in V2.10: Scaling, Dithering, Border handling, Effects, CMS, and much more... rewritten for complete CMYK(!!!) processing. Slightly faster too. I-And this is the second major step: CMS now accepts CMYK profiles and profiles with various precission. I-Saturation control added to the color window. I-Update to PNG compression library E-BNoise b/w dither method was not reentrant since V2.07. Now reentrant again. I-Separation functions/settings added. Binary CMY->CMYK and CMYK->CMY functions added beside the standard UCR/GCR functions. I-SEPARATION [0-4], UCR [0-9999], GCR [0-9999], GREYSCALE, COLOR and SATURATION [-50 - 50] Arexx commands added. Arexx Version command will now report "2" to reflect the changes. E-A problem reported by a user when printing from ARexx hopefully got fixed - even though I couldn't repeat the problem on my machine. The problem seems to cause dark/black images being printed when not using the the PANEL command prior to PRINT or PRINT WAIT. I-Blue Noise non binary dither method (previously only used by Fargo output module) now much faster. Also fixed: BNoise 30% was printed as 50%. I-Studio Version is now supplied to the output module. I-Studio will now switch to greyscale printing for a specified print density if output module doesn't support color printing for a specific resolution. For instance, a Deskjet 660C can only print greyscale at 600dpi. I-Added additional functions to Studio server for upcoming PageStream V3 server printer driver. These functions offer an easy way to a future setup window of the PageStream driver. E-Canon BJC800 output module didn't allowed paper width greater 8.5 inch. Because of this, users had to use the slower Workbench driver for printing A3. Similar problems with right margin do exist with other Canon modules when printing 180 dpi. Fixed. I-A bug in the BSC/Alpha Data Multiface III pit.device can cause a lockup of any print program with a priority below 0. All output modules will now open pit.device with a changed priority of zero unless priority was set to high by user (in this case pit.device is always accessed with priority 0 anyway). I-Canon BJC 610, Deskjet 8xx, 6xx, 1600 and PCL 5C output module with CRet and TES (REt) support added. Also drivers and profiles added for these new printers. E-CanonBJ-EC right margin problems when using a different density than 360dpi fixed. I-1200 dpi PJL and Max Res setting added to LaserDriver for Lexmark Optra 1200dpi laser printers. (not included with this update disk) 23.12.95 V2.10b C-Recompiled without SAS/C Peephole Optimizer (just to make sure... as it seems the Optimizer still didn't worked right). E-DeskDriver4C might print 3-4 unwanted characters on a page with some programs. Fixed. E-Fargo Primera greyscale printing problems fixed. I-PCL_5C output module now works with some none 100% compatible PCL 5 printers. Faster too. 20.02.96 V2.10c 20.02.96 V2.10d C-Recompiled with SAS/C Peephole Optimizer E-Fixed a CMS bug introduced with V2.10 causing minor color faults for certain colors/profiles. E-Fixed histogram/clipping function. Output was far to dark for certain images. I-Added CanonBJC4100 driver, output module and profiles (update disk only). I-Added CanonBJC 4100 SetupBJL software. 21.04.96 V2.11 I-ALL dither routines completly rewritten in order to suit upcoming optimize functions and image preview. I-Right/Left margin handling of dither routines is optimized depending on image contents. When effectiv, can lead to 1000% speed increase... I-Following functions have been translated to fast assembler code (% faster): - serpentine binary dither routines (30%) - IFF ILBM read routines (50%) - sharp/blur functions (10%) - 3d interpolation of CMS (10%) I-Added Epson SetupStylus software. I-Added StylusColor/IIS/II output module. I-Added 360*720 dpi mode to EpsonP2 I-New Stylus Color/II/IIS profiles I-Some DJ 6xx/8xx profiles changed/added I-Output modules are now listed in alphabetical order. Doubleclick can be used for selection. E-The blur/sharp filter wasn't giving full quality with Fargo Primera. I-CMSScan ink limit settings added. I-CMSScan now applies a filter to CMYK profiles removing unwanted dots in the output. This means introducing faults to the profile for the benefit of better output. E-DJ 6xx printers don't print correct at 600*600 dpi without presentation quality turned on. Drivers now automaticly enable presentation mode when needed. E-DeskDriver V2.10/V2.10b sometimes printed 3 chars on a gfx page. Fixed. 21.04.96 V2.11b E-Beseitigt Error 50 in V2.11 nach Wahl des obersten Ausgabemoduls aus der angezeigten Liste des Druckprogramms E-Das Druckprogramm verhindert jetzt Ink Limit's von 0 beim Laden der Settings. 05.05.96 V2.11c E-Printing program V2.11(b) didn't load 8 Bit IFF ILBM greyscale image with colormap correctly. Works again now... I-Installation program avoids "String To Long" error message reported by users who accidently removed the ENVARC:STUDIOPATH var. 10.06.96 V2.12 I-PageStream 3.0i Server driver added I-Improved server interface E-2 color IFF ILBM images were not loaded correctly by new V2.11 routines. Fixed E-print dimension rectangle in window was wrong for VERY large (>900 inch!) posters. Fixed 05.10.96 V2.13 I-PageStream 3.2 beta 6,7,8,9 driver added I-All binary dither routines are now up to their final speed. This increases the Studio printing program speed further by 5-60%. I-Recompiled for 68060 and full optimizer. I-Now supports progressiv JPEG/JFIF files. Note: progressiv images currently must be printed from memory. I-PNG read routines rewritten for new PNG library Version 1.0 beta 3-V0.89 and ZLIB 1.04 I-Faster image file access implemented in: IFF ILBM, IFF DEEP, PBM, PGM, Targa, Gif, PCX, PNG. I-Fargo output module (Ver3 Rev0) now writes/reads the temporary files much faster (10-15% speed increase). E-Effect window gadget scaling didn't worked for some fonts when opening the window multiple times. Fixed E-Landscape poster printing for small image on computers with much memory and a high memory setting might cause the second row of pages to get inverted. Fixed E-Studio could have crashed if an error occured while reading the image data of a PNG file. Fixed. E-IFF read buffer underrun could cause Error 48 while reading IFF ILBM images. A rare bug in the original Commodore IFF source. Fixed. E-Following serpentine(!) dither had a bug that might have caused a crash in Studio V2.11&2.12: Stucki, Jarvis and Sierra3. Again, only serpentine methods were affected. Fixed. COPYRIGHT/DISCLAIMER Copyright ©1991-96 Wolf Faust. All rights reserved.
