White lines after trapping PDF file created in InDesign

[greenhornet]

We are experiencing white lines in InDesign PDF fiiles after running them through RAMpage. We are wondering if it is a layering interpretation between RAMpage and InDesign. Anyone seeing these issues and are there any fixes? TIA

are your CT's set to choke in your trap setup? try spreading them, or not trapping CT's

You could also try deselecting dual rasterization in your Rip profile, this has worked for me at times.

I forgot to mention we usally get white lines because of transparency
usage on the page.

Dual rasterization on and contones set to knockout. Only seeing it in Indesign files and files PDF'ed from InDesign. Thanks for the respone will let you know what happens.
