44-34 Managing Color in PostScript ApplicationsColor Reference Guide for C9800 - 34Using CMYK simulationsYou can specify a CMYK Simulation profile and a CMYK simulation method for a jobusing the CMYK Simulation Profile and CMYK Simulation Method print options(see the Color Guide Chapter 1). The CMYK Simulation setting affects all CMYKcolor data sent by the page layout or illustration application. It can also affect RGBdata sent to a page layout application if RGB Separation is set to Simulation.• If the document contains CMYK graphics that were separated for an offset pressstandard, apply the corresponding CMYK Simulation setting. For example, forgraphics separated for SWOP, choose SWOP as the CMYK Simulation setting.If you print separations to the Fiery and choose to use the Combine Separationsfeature in conjunction with Full Simulation, the result may not match that of thesame page printed as composite.• If the document contains CMYK graphics that were separated according to the colorcharacteristics of a custom ICC profile (not a press standard profile), specify thecorresponding profile as the CMYK Simulation Profile setting on the Fiery.For more information on downloading CMYK Simulation profiles to the Fiery withColorWise Pro Tools, see the Color Guide Chapter 3.Using application-defined halftone screensIf your site has installed the Fiery Graphic Arts Package (not available for all Fierymodels), you can define halftone screens from several PostScript applications and usethem when printing. The results vary depending on the application.To define a halftone screen, use the application to adjust the Frequency and Anglevalues of the halftone screen. For applications that use the Fiery default (InDesign,FreeHand, QuarkXPress, and Illustrator 10), the ink dots are round; for applicationsthat define their own shape and do not use the Fiery default (PageMaker, Photoshop,and Illustrator 9),the halftone dots may be a different shape. When you print the job,choose Application Defined for the Halftone Screen print option.
