11-8 Fiery Color Management• None instructs the Fiery to allow the RGB sources you defined elsewhere, such as inthe application, to be used. When you set RGB Source to None, the appearance ofcolors will not be independent of the file type. For example, RGB EPS files will lookdifferent from RGB TIFF files.With RGB Source set to None, PostScript RGB data that contains a source colorspace definition is converted using the CRD specified by the Rendering Style option(see page 1-6). Non-PostScript RGB data and PostScript RGB data that does notcontain a source color space definition are converted using a general undercolorremoval (UCR) conversion method.RGB SeparationThe RGB Separation option determines how RGB colors (as well as Lab and XYZcolors) are converted to CMYK. The name of this option is meant to be descriptive,since the option defines the color spaces that will be used by the Fiery to “separate” theRGB data into CMYK values.The two choices available for this option determine whether RGB data is convertedinto the full gamut of the copier/printer (output) or is first converted into the gamutof another digital printer or press standard (Simulation). This feature is helpful formaking one device behave like another for RGB data. For example, if a high-qualityICC profile is available for another print device, the copier/printer can simulate thebehavior of that device.RGB Separation is also useful for prepress applications. For example, it lets youexperiment with the appearance of an RGB scan under different press printingconditions, without having to convert the RGB data to CMYK data for eachcondition. When the desired printing condition is found, you can then convert thefile to CMYK, using the same CMYK simulation profile you used during theexperimentation.N OTE : The RGB Separation print option should be used in conjunction with theOutput Profile or CMYK Simulation Profile print options.• Output converts all RGB colors into the CMYK color space of your copier/printer(when set to the printer’s default), or a customized CMYK color space for yourcopier/printer (when set to Output 1-10).
