Export to PDF different sizes from Artboards

[Tobi755]

Hi,

I have a file with 72 pages (done with the artboard). The export to PDF looks fine, but when I want to send the PDF to a print shop, they refuse it as the pages have different sizes/formats.

All artboards are copied from one "master" but some of the pages (20, page 2 to 21 from 72) create the error. I already tried to copy a "correct" page and delete the faulty page, but the result is the same. Also Adobe Preflight shows the same error message.

Does anyone have an idea, what I could try to get this fixed?

Thanks

Tobi

Hi Tobi755,

Are all the artboards the same size?

If possible could you provide the file in question?

Thanks

Callum

Hi Callum,

as far as I can see, the artboards have the same sizes. I deleted all conten from the file and checked, if the problem persists, and yes the same problem is mentioned from the print shop.

Thanks

Hi Callum,

did you have a chance to check the file?

Any idea, what might be the problem?

Thanks

Tobi

I don't have personal experience with this, but from what I've read in the forums it's important that your artboards be located on integer x/y coordinates with respect to the pixel grid. If you open that .afdesign file, then switch the document units to px (Document setup...), and then look in the Transform panel, you'll see that many of your artboards have non-integer coordinates. For example, Seite 70 has a Y value of 89291.3 px, Seite 69 has an X value of 2362.2 px, etc.

When artboards are not aligned on the pixel grid the Export process will often add an extra pixel to the height or width.

I suspect that's what is happening with this document, and it would give you PDF pages that are a pixel different in size.

Thanks Walt,

I also found this explanation somewhere and realigned all artboards to full millimeters. Did not think about pixels. So I realigned all artboards now to full pixels and voila: it works

Thank you very much

You're welcome.

I find myself wondering, though, how one is supposed to ensure that one's artboards are aligned to whole pixels if one has set the document units to be one of the non-px choices. I'll have to experiment with that, unless someone else can provide the answer

I think using "Force Pixel Alignment" should do it, if necessary by selecting each artboard with the Move Tool & moving it slightly in any direction.

Thanks. Yes, that would do it, and I was forgetting about that option.
