The 14 ways a sponsor activation PDF fails its printer

If you run sponsor assets for a festival, you already know this list. It's the same 14 failures every year, every sponsor, every event.

Here's the list. It's useful for two reasons: if you know what your printer is going to reject, you can catch it earlier, and if you're evaluating whether to automate this, it's a test. An ops tool that doesn't catch at least 10 of these isn't worth paying for.

1. Wrong trim size. Sponsor sends 8.5×11 when the program is actually 8.25×10.875. Printer catches it, page is off-register.

2. No bleed. Sponsor sends trim-size PDF. Printer can't run it through the cutter without creating a white line at the edge. Reprint.

3. Wrong bleed amount. Sponsor includes bleed but only 0.125" when the printer specified 0.25". Image gets trimmed too aggressively.

4. Content in the trim zone. Bleed exists but text or logo runs into the bleed area. Gets cut off.

5. RGB instead of CMYK. Common with logos exported from Figma. Colors shift on press. Sponsor asks why their blue looks green.

6. Mixed color space. Some elements CMYK, some RGB. Unpredictable press behavior.

7. Missing Pantone spot color. Sponsor spec'd PMS 288 but it's not defined in the PDF. Printer substitutes with process CMYK, color is slightly off.

8. Low DPI source art. The PDF is technically 300 DPI in the "Export As..." dialog, but a 72 DPI screenshot was placed inside it. The placed image is pixelated.

9. Fonts not embedded. Sponsor used Helvetica Neue but didn't embed it. Printer substitutes with Helvetica. Kerning shifts, line breaks change.

10. Transparency on spot color. 80% opacity over a PMS ink. Presses can't render this predictably.

11. Rich-black text. Black body text built as CMYK 75/68/67/90 instead of 0/0/0/100. Causes misregistration halos on small type.

12. Live links in print PDFs. Hyperlinks embedded in the PDF. Printer can't do anything with them; just a visual risk if any weird metadata preview is rendered.

13. Wrong page count. Program is 32 pages, sponsor delivers a 34-page PDF "just in case." Now the pagination is off and the print vendor has to isolate the sponsor's 2-page spread manually.

14. Oversize file. 800 MB PDF because raster art was placed at 1200 DPI instead of down-sampled to 300. Printer's RIP chokes.

What's automatable.

10 of these 14 can be caught deterministically in the partner's browser before upload, zero AI required:

• #1, #2, #3, #4: trim / bleed / content-zone via PDF box parsing
• #5, #6, #9: color space and font embedding via PDF stream inspection
• #13, #14: page count and file size via metadata read
• #11: text color inspection

2 more need AI-assisted analysis (Claude reading the embedded text):

• #8: low-DPI placed image detection
• #12: printable-element anomaly

2 need the printer's own RIP to fully diagnose (#7 spot color, #10 transparency-on-spot), but we can surface strong warnings for those.

That's 12 of 14 failure modes you never have to look at again.

Every one of them costs a sponsor cycle at least one round-trip. Round-trip is 2-4 days. 12 failures averaged across 60 sponsors per event is a staggering amount of time that gets spent on nothing that matters.
