Use overprint commands
This option controls the interpretation of transparency and overprint
commands in PDF and PostScript documents.
• If disabled, transparency and overprint commands are ignored. All
elements will be opaque.
• If enabled, transparency and overprint commands are interpreted.
This might produce invisible page elements if the transparency has
been defined incorrectly in the DTP system. In this case you have to
redefine the transparency of the invisible objects in the output document.
Use trapping
This option controls the interpretation of trapping commands, e.g. those
created in QuarkXPress. If the option is disabled, trapping commands
are ignored when converting the PostScript document.
Complex transparency for overprinting grayscale
images
This option is only applied to grayscale images set to overprint in the
PDF or PS file and only if the USE OVERPRINT COMMANDS option is enabled.
The grayscale images will be set to transparent in cyan, magenta and
yellow, and the black of underlying objects will be added to them.
Example:
If an overprinting grayscale image with 20% black is on top of a tint
with the colors Y90 M100 C0 K10, the resulting density where the two
layers intersect will be Y90 M100 C0 K30.
