A PS/ PDF SeparationIndividual layer of a multi-color image. Each layer contains the amount of each primary color needed to produce a four-color image when layers are superimposed on each other. Files are a format that has separate data for each color channel. There may be a single file or several different files (one for each color channel). Configuring the options for PS/PDF Separation Files allows RIP-Queue to correctly process these files.

 

To configure the [PS/PDF Separations] Options:

1. From the “PS/PDF Separations” screen, enable the Separation File] checkbox.
2. Choose the type of separations from the [ColorThe attribute of visual experience that can be described using the dimensions of Hue1. A tint or color specified by an angle on the HSV Color Wheel. Going counter-clockwise around the wheel, hues shift from red to yellow to green to cyan to blue to magenta and finally back to red. 2. The attribute of a color that permits it to be identified as a specific color. Hue combined with Saturation and Value fully defines a color., Saturation, and Brightness. Separations] drop-down menu.
3. If necessary, modify the number of Spot Separations.
4. Choose the Color Order of the PS/PDF File. If you do not know the color order, check the original PS/PDF file using the application it was created with. You can manually modify the Color Order by selecting Custom a pull-down menu and using the Move Up and Move Down buttons.

 

NOTE: The [PS/PDF Separations] options must be configured properly for the image to process correctly. Non-separated PS/PDF files will cause PostScript errors during processing when the Separation File checkbox is selected. When using Quick Sets in RIP-Queue only set PS/PDF Separation Quick Set options if you will always use separated PS/PDF files of the same separation format with the Quick Set.

When the Auto-detect separations option is activated, the following information is automatically detected for separation files: 

• Color Separations
• Spot Separations
• Color Order

When the Auto-replace Spot Colors option is activated, defined colors in the Spot Channel Replacement dialog are referenced first. If spot colors have not been defined in the Spot Channel Replacement dialog, the spot color information defined on the [PS/PDF Options] is referenced. Spot colors within files can be converted to various color spaces for printing on printers with different ink configurations. For example, the spot colors in a CMYKSS file can be converted to 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 RGBSystem for describing colors based on a combination of values for Red, Green, and Blue—the additive primaries. RGB is the basic additive color model used for color video display. Mixing various percentages of red, green, and blue light can recreate most of the spectrum; combining 100% of all three creates white light. See CMYK, Additive Color.. so the file can be printed correctly on a CMYK printer. 

 

NOTE: If the Auto-replace Spot Colors checkbox is left unchecked, the defined colors in the Spot Channel Replacement dialog will not be referenced.
