To open the Color Matching Table (Figure 1), select Setup > PostScript > Color Matching Table.

1. Open the Color Matching Table, and click the Replace button. This opens the Replace dialog (Figure 2).
2. In the Search For field, type SPOTCOLOR.
3. In the Replace With field, type a name for another swatch color with a suitable format. NOTE: Color names are case sensitive.
4. Click OK.
5. From the toolbar, click the Edit Quick Sets button. This opens the Edit Quick Sets dialog (Figure 3).
6. Select the Quick SetA group of settings that is applied to images to create jobs in an efficient manner. you want to edit, and click the Edit button. This opens the Edit Quick Set dialog (Figure 4).
7. Click the Advanced button.
8. In the Edit Quick Set-Advanced Options dialog, select the PostScript tab (Figure 5).
9. In the Spot ColorA specific color or type applied to individual graphic items. Replacement section, activate the Use Color Table option.

The Color Matching Table only works with PostScript files. It allows you to use the name of the color, instead of the CMYKSystem for describing colors based on a combination of values for Cyan, Magenta, Yellow, and Black; the ink colors used in four-color process printing. In theory, 100% of Cyan, Magenta, and Yellow create Black. In practice, the addition of Black ink is necessary to print a true Black. See also RGB. equivalent, to communicate color meaning.

 

NOTE: The names specified in the Color Matching Table must match the names of the colors used in the PostScript file. If RIP-Queue doesn't find a name used in the PostScript file, it uses the CMYK equivalent.

 

In order to use the Color Matching Table option, you must have the following:

• A PostScript that specifies colors by name.
• A Color Matching Table that contains those exact colors names.

 

There are two .eps files that may be useful for testing purposes. These files are the ClrChartC.eps and ClrChartU.eps. These files correspond to Coated and Uncoated colors and can be used in conjunction with properly named spot colors.

 

TIP: After ripping your PostScript file, look at the contents of the RIP Log. This log will contain a list of any named colors in the PostScript file that do not have a suitable match within RIP-Queue. Once you have a list of named colors without suitable matches, you can use the Replace button in the Color Matching Table to modify the names or use the Add Alias option to add the suitable names. The Replace button is the quickest alternative.

The Input ICCICC (International Color Consortium) A group of hardware and software companies dedicated to the development of a specification that is operating system independent and provides the digital imaging, printing and related industries with a data format for defining the color and reproduction characteristics of devices and their related media profile is not used if you activate the Color Matching Table option. It always uses the default printer profile for the Color Matching Table. The Rendering IntentA method of mapping color values so colors can be reproduced on different devices, even if the devices have a different gamut. As part of this process, it determines how in-gamut and out-of-gamut colors are mapped. Different methods of compressing are used depending on the rendering intent selected so out-of-gamut color values so they can be reproduced. is specified by selecting PostScript > Configure RIP.

 

To set the Rendering Intent:

1. In RIP-Queue, select Setup > PostScript > Configure RIP. This opens the Configure RIP dialog (Figure 6).
2. Scroll down the list until you locate the SPOTRENDERINTENT option.
3. Select this option, and click Edit.
4. Select which spot rendering intent you want to use:
   • 0 is Perceptual
   • 1 is Absolute
   • 2 is Relative
   • 3 is SaturationTerm used to describe the strength, purity, or vividness of a hue. Saturation indicates how much color is present. When there is no saturation, there is no color; the more saturation, the more color there is of the given hue.

The System Defined Colors Tab lets you manage colors that are defined by RIP-Queue. For more information, see System Defined Colors.

The User Defined Colors Tab lets you manage colors that you define. For more information, see User Defined Colors.
