I think the media box can be the same size as the bleed box though, just no smaller. Hi Jessie,

As I understand it, to be PDF/X-1a compliant, the file requires a bleed box defined even if the job itself does not require bleed i.e. bleed box should be equal to trim box in that scenario.

I think the media box can be the same size as the bleed box though, just no smaller.

I was just wondering if anybody can tell me whether black and white PDFs with a greyscale icc profile set as output intent complies to PDF/X-1a:2001? I know greyscale images are allowed in PDF/X-1a but not sure about output intent. It looks like PDF/X-3 mentions black and white printing but not PDF/X-1a. Thanks in advance for any info, Anthony Hi, great job with the site.

I wasted my time and money on Acrobat X Pro. It does not work. Preflight in v. X does not work either. Also Quark v.9 says it creates PDFX-1a compliant files, but its pdf engines are flawed too, it does not work either. Wits end!

Thanks, Joe Must a PDF/X-1a:2001 PDF be version 1.3 or can a version 1.6 PDF be converted to PDF/X-1a:2001?

Thanks,

It must be larger than the TrimBox/ArtBox, but smaller than the MediaBox." If the Bleed box is the same exact size as the the media box, but larger than the trim or art box, the document is still a valid PDF/X1a, is it not?

That prize surely goes to Serif PagePlus, which is about £110 cheaper (£80 v. £190) It’s worth noting that Adobe is not the cheapest PDF/X-1a producer.

PDF/X3. PDF/X3 is used more and more in digital printing where the conversion to CMYK is done at the RiP level. This is incredibly effective for wide format printing where the source RGB to destination CMYK is done at the RIP. We build both 1a and 3, now 4 with supports transparency. I was not aware of 5. Also thanks for the GWG site! Great job – except I disagree on one thing. PDF/X3. PDF/X3 is used more and more in digital printing where the conversion to CMYK is done at the RiP level.
