Signing off on a label proof feels routine, until something goes wrong on press and you’re staring at a stack of finished labels with a missing vintage year, a misaligned graphic, or a color that doesn’t match what you saw on screen.
Most of those surprises trace back to two specific factors that are easy to miss when reviewing a PDF proof: how the proof appears on your screen and how it prints on your office printer. Both are controlled on your end, in your PDF viewer, and both can quietly mislead you if you don’t know what to look for.
The short tutorial below walks through exactly what to do.
If you’d rather read than watch, here’s the quick version.
1. Print your proof at actual size
When we send you a proof, it’s a PDF set to the exact dimensions of your finished label. That matters because if the label is small enough to fit on standard paper, you can print it, cut it out, and physically place it on your bottle or jar to confirm it looks right and actually fits.
The catch: most PDF viewers default to shrinking the proof down to fit on letter-size paper. That defeats the entire point. A label that “looks good” at 87% will not look the same at 100%.
In your print dialog, look for a scaling setting. Depending on your PDF viewer, it might be labeled:
- Actual size
- 100%
- Do not scale
- Scale to 100%
The exact wording varies. Adobe Acrobat and Adobe Acrobat Reader use “Actual size”; other viewers phrase it differently. But they all mean the same thing: print the file at the dimensions it was created at, with no resizing.
To make verification easy, every proof we send includes a small ruler marked at 3.5 inches. After you print, hold a real ruler up against ours. If the two match, you’ve printed at actual size. If they don’t, your printer scaled the file down. Adjust your print settings and try again.
2. Turn on Overprint Preview
This one is more technical, but it’s the difference between catching a problem on a proof and discovering it on a finished press run.
Overprint Preview is your PDF viewer’s way of showing you how a document will actually look when printed on a professional press, rather than how it appears on a screen or from an inkjet printer. When it’s off, you’re seeing a screen-friendly approximation. When it’s on, you’re seeing a much closer simulation of what the press will actually produce, including how overlapping inks will interact.
Here’s the problem: in Adobe Acrobat and Adobe Reader, Overprint Preview is off by default for most files. You have to turn it on yourself.
How to enable it in Adobe Acrobat or Adobe Reader
Open the Preferences menu (called Settings in some versions). Go to the Page Display pane. You’ll see an option for Use Overprint Preview, which by default is set to “Only for PDF/X files” — meaning it’s effectively off for the proofs you’re looking at. Change it to Always.
Why it matters: a real example
In the tutorial video above, you’ll see a proof for a wine label with the vintage “Syrah 2023” set in a very light yellow over a mustard-colored background. With Overprint Preview off, the year reads just fine. The proof looks correct, and you’d be tempted to sign off on it.
Turn Overprint Preview on, and the year disappears entirely.
What’s happening: the light yellow text was set to “overprint” the background. A screen or an inkjet printer mostly ignores that setting, so the text shows up. But a professional press honors that setting literally, and a very light color overprinting a darker color will be invisible. If you approved that proof without Overprint Preview enabled, you’d never know the vintage year was going to vanish until your labels arrived.
This is exactly the kind of issue our pre-press team works to catch and flag back to you before sign-off. But Overprint Preview gives you a second set of eyes on it, and lets you spot anything that should be discussed before the file goes to press.
A quick checklist for proof review
Before you sign off on any proof, run through this:
- Printed at actual size (verified against the 3.5″ ruler on the proof).
- Cut out and hold against the actual product or container where applicable.
- Viewed on screen with Overprint Preview turned on.
- All copy reads correctly — vintage years, ABV, net weight, ingredient lists, addresses, allergen statements.
- Colors and finishes match expectations.
- Any questions or flags we sent over have been addressed.
When something looks off, tell us.
If anything in your proof looks wrong, or if you turn on Overprint Preview and something disappears or shifts in a way you weren’t expecting, flag it back to us before you approve. That’s exactly what the proofing round is for, and we’d rather make the fix now than discover it after the press is running.
If you’re not sure how to enable Overprint Preview in your specific PDF viewer, or you want a second opinion on what you’re seeing, just reply to your proof email. We’re happy to walk through it with you.
