Setting Image Quality options
The Options FAB in the Job Properties: Image Quality tab contains
controls for the following options:
• Trapping
– an image processing technique used to compensate for
misregistration in a print engine or press. Misregistration
results in white gaps and shifted hues.
– can be set by selecting the corresponding check box
• Black Overprint
– an Image Quality enhancement process performed during
RIP that prevents the background of a black object from
being removed. With the black being printed over the other
color layers, any misregistration in the print engine or
press will not result in white gaps.
– can be set by selecting the corresponding check box
• Anti-Aliasing
– a method for reducing the jagged appearance (caused by
rasterization) of curves and diagonal lines. Anti-Aliasing
enhances the smoothness of such curves and lines.
– can be set by selecting the corresponding check box
