[. . . ] The Creo anti-aliasing causes blends to appear smooth with no banding and diagonal lines to appear crisp without jagged edges (do not use this option with VI jobs). Normal provides standard text quality. Image Quality High provides superior image quality. This setting applies the Creo proprietary smooth scale algorithm, which improves the quality of images containing several resolutions (such as images taken from the Internet). Normal provides standard image quality and increased RIPing speed. Trapping Yes applies the Creo FAF (Full Auto Frame) algorithm to the job. Trapping solves misregistration between color separations in offset and digital printing. This problem results in white lines around objects on top of a background (in a knock-out procedure) and also between adjacent colors. The FAF solution is to extract the element or background to create an overlap between them. No does not begin image trapping while RIPing (this does not affect trapping incorporated by the authoring application). If trapping was applied in the authoring application, select No. Image Noise No (default) applies no image noise to your job. The higher the level, the smoother the vignettes appear. Setting PPD Parameters from Client Workstations 235 PPD Parameter Black Overprint Printing Options Yes provides better printing quality (as in FAF) and a richer, deeper black with the underlying CMY values equal to the those of the printed background. Black Overprint ensures that 100% black text prints cleanly within a tint or picture area. Occasionally white lines may appear around black text and the text may appear less dense than required as a result of misregistration between color separations. With Black Overprint, the Pure Black Text / Graphics option is automatically activated and there are no knock-outs under the black text. This results in less color density and can cause misregistration if separations are not perfectly aligned. No leaves the job as is. PS Overprint PS (PostScript) Overprint offers the option to use the overprint, which exists in the PS file. It also determines whether the DTP application PS Overprint settings are honored in the RIP. CXP3535 Color Server settings override PS Overprint commands from DTP applications. For example, if PS Overprint was set to Yes in a DTP application, selecting PS Overprint No in the CXP3535 Color Server results in no overprinting. The CXP3535 Color Server can not create PS Overprint that is not pre-defined in the file. Selecting PS Overprint Yes for a file that has not had overprinting defined in a DTP application does not result in overprinting. Yes (default) instructs the RIP to use the overprint information that exists in the input PostScript file. Also, if PS Overprint is applied in a DTP applications, it is implemented by the CXP3535 Color Server. For example, in the case of a yellow triangle overlapping a cyan circle, selecting Yes results in the overlapping area turning green. This is not seen on the screen, only in print. No ignores the overprint information that exists in the input PostScript file. Background colors are knocked out and only the top most color parts are seen on the screen in your DTP application. For example, in the case of a yellow triangle overlapping a cyan circle, selecting No results in the cyan background being knocked out, so only the yellow is printed. 236 Chapter 5 ­ Working from the Client Workstation PPD Parameter Brightness Printing Options Brightness settings can be applied to RTP jobs without reprocessing (reRIPing the file). Normal keeps the current job setting and does not apply extra brightness. To apply brightness, select one of the range options: Light (5%), Lighter (10%), Lightest (15%), Dark (5%), Darker (10%), Darkest (15%). Contrast Contrast settings can be applied to RTP jobs without re-processing (reRIPing the file). Normal keeps the current job setting and does not apply extra contrast. To apply contrast, select Less Contrast or More Contrast. RGB Workflow This option changes gamma values, thus producing more color depth for RGB images. [. . . ] Sheet of printed pages which when folded becomes part of the publication. Spectrophotometer (X-Rite DTP41), which is a 24 band color measurement instrument that reports densitometric, colorimetric and spectral data. An additional separation (fifth, or more) that is used with special inks to achieve difficult color combinations, such as gold, or chocolate brown. Spot color is sometimes used by graphic artists to define special corporate colors, for example, for company logos. [. . . ]
