I'm working on a book with facing pages that will be perfect bound. When I create a PDF by printing a postscript, it comes out very strangely... it seems to be removing part of the bleed on the right facing page, which results in a book that won't be trimmed evenly. I can't seem to figure it out... I've attached two screenshots that show how it appears in InDesign, and how it appears in the resulting PDF.
based on your screen shots, it seems like your pdf is showing Bleed Marks and not trim marks. If that is the case, your pdf is exactly as I would expect it to be.
You don't have and color in the bleed area, so the red only goes out to the trim marks in the center sides, because it is picking up red from the facing page. Check your printer mark settings when you make the pdf - you need crop or trim marks to show. You also need your red to go out to the edges of your bleed area in InDesign, to allow for slight variations in trim accuracy.
Yes, these are bleed marks because I am trying to show that the bleed is uneven (and I do understand that images need to extend beyond the bleed, again this is for demo purposes).
What I don't understand is why the outer bleed on the right facing page is smaller than the one on the left. Shouldn't the outer bleed be the same based on what you see in the screenshot from within InDesign? When these pages are stacked together and trimmed, won't this result in either overtrimming all the left-facing pages or undertrimming the right-facing ones?
Dunno. When I was using print to postscript I didn't have the issue. I can make some tests...but it would be apples to apples if you uploaded the test document above to dropbox.com and provide a link.
Take care, Mike
There was, and still is, as far as I know, a bug in how bleeds are set in facing pages when exporting. Outside translates to left, and inside to right on both pages, so if the bleed setuyp is uneven you can get bad results.
I have found that it doesn't happen when I just export to PDF. Only when I do postscript... so maybe it could be a problem with Distiller?
For going to a postscript file, you are going to need to add the inside bleed. Result should be identical to doing the export to PDF. At least for this simple example file. Cannot remember properly, but I think you also need to use centered instead of upper left...but I could be wrong.
Take care, Mike
