This has been an ongoing issue since quark 8.1. We are using a Xinet OPI server. When we make a thin PDF from quark and it goes through an OPI workflow the resultant PDF has inconsistent outputs. A lot of the time text can be cropped by the canvas size of a picture. Or pictures do not bleed correctly.
