phantom stroke??

[bigdave]

On objects and groups with a transparent background I'm getting a phantom key line stroke printing. It's not there on the indesign document nor is it there on a press quality pdf but prints on both & is only over sections which already have colour (see photo)

So far I've tried, knockout group, transparency settings, object stroke and fill to no avail.

Anyone able to offer an insight into this?

Have you tried saving it as a PDF/X-4:2007 compliant file? This can sometimes help with transparency issues. Either that or work around the transparent object by creating a path in Photoshop?
I don't know how the file was created or what kind of transparency you're using, but there are a few things you can possibly do depending on the application. :icon_confused:

I'll give it a go on Monday. Cheers.
