Image Quality Options FAB
The Image Quality tab > Options FAB contains options that can be

misregistration in a print engine or press. Misregistration

For additional information, see: Setting up Trapping
• Black Overprint

press will not result in white gaps.
– can be set by selecting the corresponding check box

rasterization) of curves and diagonal lines. Anti-aliasing
enhances the smoothness of such curves and lines.
