 ===========================================
 1. Features
 ===========================================
 The PS Gamma Adjuster feature can adjust an amount of each of the primary
 colors (Cyan, Magenta, Yellow and Black) that make up a color output to a
 PostScript printer. 
 This feature enables you to obtain the color you expect, by controlling the
 component amounts of primary color toners by the software when you could not
 obtain the color you expected.  This feature can be used to adjust the dot
 gain of the component amount of each primary color, and control the amount of
 toner that is transferred as well.  You can designate the definition of the
 gamma curves that you create, at the time of printing once you register it in
 the PPD file or SPD file of a PostScript printer.


 ===============================================
 2. Operating environment
 ===============================================
 This utility requires the following:
 Windows 95/98/Me
 Windows NT4.0
 Windows 2000/XP/Server 2003
 Windows XP x64 Edition/Server 2003 x64 Edition
 Windows Vista/Vista x64 Edition
 Windows Server 2008/Server 2008 x64 Edition

 AdobePS4.1 and above printer drivers, and Pscript4.0 and above printer
 drivers.

 (Notes)
  The PS Gamma Adjuster does not run with Windows PCL printer drivers.


 ===============================================
 3.  Using the PS Gamma Adjuster
 ===============================================
 To see how to use this utility, click [Help] button on each screen of the 
 Utility.  

 - How to register gamma curves.
 (1) Select [Start] - [Programs] - [Muratec] - [PS Gamma Adjuster]
     - [PS Gamma Adjuster]
 (2) From [Select printer], select a printer. 
     (Note)
     Some applications (Adobe Pagemaker, etc) use their own PPD file when 
     printing.
     For them, select [Select PPD for Application], click [Browse] and select 
     the PPD file that the application uses.  
 (3) Click [New].
 (4) Adjust the gamma curve by any one of the methods shown below, enter a 
     name in [Gamma Curve Name]text box, and click [OK].
     - Manipulate the gamma curve line directly. 
     - Enter a gamma value, and click the [Gamma Setting] button.
     - Enter a value in each density text box. 
       The gamma curve name you created above is displayed in [Available 
       Gamma Curves] list.
 (5) Select the name you created in (4), in [Available Gamma Curves] list, 
     and click [Add ->].    
     The newly created the gamma curve name is displayed in [Printer's Gamma
     Curves] list.  
 (6) Click [Apply].
     The newly defined name displayed in [Printer's Gamma Curves] list is 
     registered in the PPD file. 
     (Note)
     You can register up to six gamma curves in one PPD file.
     In some models, however, not all the registered names are displayed at 
     once on the printer driver settings screen.
 (7) Click [OK] on the screen to complete the registration to PPD.
 (8) Click [Exit] to close the PS Gamma Adjuster.

 - How to designate defined gamma curve name for printing
 (1) Start the application.
 (2) Select [Print] in [File] menu.
 (3) Click [Properties], and open [Color] tab. 
 (4) Select the gamma curve name in [Custom Gamma Adjustment] menu and print.

 3.1 Tips on gamma curves
 -----------------------------------------------
 To adjust the entire image by using a specific color as reference, you 
 calculate the amount of dot gain from the difference between the component 
 amount of each primary color of the specific color and the actually-printed 
 component amount of each primary color of the specific color, and reflect it 
 in the graph. 
 For example, from the print result of red that has the composition of C=10%, 
 M=90%, Y=80% and K=5%, you guess that magenta portion lacks 5% while yellow 
 portion has a 3% excess.  In this case, the amounts of dot gain are M=90%: 5 
 and Y=80%: -3.
 Here, uncheck [All(CMYK)], click [Magenta], and enter the value 95, which is 
 the sum of the lacking 5% and 90% of the text box.  Similarly, click 
 [Yellow], and enter the value 77%, which you get after subtracting the 
 excess amount 3% from the 80% of the text box.   
 
 When RGB is used, please follow the instructions below:
 For darker red over the entire image, increase the value of cyan.
 For darker blue over the entire image, increase the value of yellow.
 For darker green over the entire image, increase the value of magenta.
 For lighter red over the entire image, decrease the value of cyan.
 For lighter blue over the entire image, decrease the value of yellow. 
 For lighter green over the entire image, decrease the value of magenta. 


 ===============================================
 4. Cautionary Notes
 ===============================================
 - Using the PS Gamma Adjuster feature may result in slow printing. 
   If you wish to place the priority on the speed, select [Not Specified] 
   in the [Custom Gamma Adjustment] menu in [Color] tab.
 
 - After you register the gamma curve name, [Custom Gamma Adjustment] menu 
   or its contents may not be displayed in the printer driver's [Color] tab.
   If this occurs, restart the computer. 

 - Before you print, you need to restart the applications that were already 
   started before you registered the gamma curves. 

 - Some applications have the feature that designates the adjustment of the 
   dot gain and the adjustment of the component amount of each primary color, 
   at the time of printing, or the feature that includes those settings in 
   EPS file.
   If you wish to use these features of the application, select 
   [Not Specified] in the [Custom Gamma Adjustment] menu in [Color] tab.

 - Even when multiple printers of the same model exist on the network, only 
   one printer name is displayed in the list of [Select printer] of 
   the PS Gamma Adjuster.  
   The gamma curve name that has been registered, however, becomes effective 
   on all the printers of the same model. 


 ------------------------------
 4.1 On PageMaker 6.5
 ------------------------------
 In [PPD] of [Print] dialog, select the printer name for which the gamma 
 curve name has been registered, click [Features] button, select the gamma 
 curve name in [Custom Gamma Adjustment], and print.
