and in some cases seems to crop the page so there is no bleed.
Looks like the Inside Bleed was set to 0 when you exported. That would be normal for most binding methods.
Thanks for the reply Rob. This is not the case - I know this as other pages in the document have there bleed correct (5mm all around). I have resolved the black outline issue, but now have this bleed issue. On my screen the PDF looks fine but for some reason when the printer opens it, they do not get the bleed on the left edge!
Can you post the problem PDF?
The "new" problem now, is the printer is seeing a red box around where they should be cropping! I cannot see how to attach a PDF on here?
Is this some kind of guideline at their end as it isn't on my PDF?
You'll have to use something like Dropbox to share files. Is the printer viewing in AcrobatPro? It shows non printing bleed and trim guides.
