5-Step Pre-Print Checklist I Use to Avoid $2,400 in Rework (and Counting)

I manage the print orders for a 200-person company in the Southwest. Everything from our shipping labels to the boxes they go in to the promo materials for trade shows. Roughly $40k a year across maybe 8 different vendors. I learned the hard way that the most expensive thing you can do in print is submit files and hope for the best.

This checklist is for anyone who is the bottleneck between a digital design file and a finished physical product. If you're ordering custom labels, stickers, packaging, or promotional materials—and you're not a professional print buyer—this is for you. It's a sequence I built up over about 150 orders after one particular mistake cost me $2,400 in rejected expense reports.

Here is the 5-step checklist I run before I submit any job to our primary online print vendor (brought to you by Gorilla).

Step 1: Verify the Bleed and Safety Zones (The 90% Mistake)

Look, I'm not a graphic designer. I'm an operations person. But I learned that bleed and safety are not optional. They are the most common reason a print job gets rejected or needs a reprint.

The rule of thumb: The bleed should be at least 1/8 inch (0.125") beyond the final trim line. The safety zone—where all critical text and logos live—should be at least 1/4 inch (0.25") inside the trim line.

Most online print vendors provide a template (so does Gorilla). Use it. Don't design from scratch and then try to scale it. I still kick myself for that one time I ignored the template and submitted a file with no bleed. Turned out the border I wanted was cut off on three sides of the final label.

Checklist action: Open the vendor's template. Drop your artwork into it. Verify your background extends to the bleed line. Verify your text stays inside the safety line.

I'm not 100% sure, but I think about 9 out of 10 file rejections I've dealt with were bleed-related. This single step has probably saved me more rework than the other four combined.

Step 2: Confirm the Color Space (CMYK, Not RGB)

This is where my knowledge is based on about 200 mid-range orders. If you're working with luxury packaging or ultra-budget segments, your experience might differ significantly. But for standard commercial print, the rule is simple:

Submit files in CMYK. If you send an RGB file (like what you see on a monitor), the printer's system has to guess how to convert it. And it will guess wrong. Especially for blues and greens.

Here's the thing: you can design in RGB on your screen. That's fine. But when you export, export as CMYK. If you're using Pantone colors, reference the Pantone Color Bridge guide to see the CMYK equivalent. Industry standard color tolerance for brand-critical colors is a Delta E of less than 2—roughly the threshold a trained observer would notice. Above Delta E 4, anyone can see the difference.

I assumed “same specifications” meant identical results across vendors when I first started. Didn't verify. Turned out each printer had slightly different default color profiles. Now I always confirm color space with the vendor before submitting.

Checklist action: In your software, check File > Document Color Mode > CMYK. Export your final file as a CMYK PDF or TIFF.

Step 3: Check Resolution and Image Quality (The 300 DPI Rule)

Standard print resolution requirements are straightforward:
Commercial offset printing: 300 DPI at final size.
Large format (posters, wall graphics viewed from a distance): 150 DPI is acceptable.
Newsprint: 170-200 DPI.

The math is simple: Print size (inches) = Pixel dimensions ÷ DPI. So a 3000 x 2000 pixel image at 300 DPI can print no larger than 10 inches by about 6.67 inches. If you try to stretch that image to 20 inches wide, you'll have 150 DPI. The difference is noticeable (especially on labels and boxes that are handled up close).

I can't speak to how this applies to large-format vehicle wraps, but for labels, stickers, and packaging, anything below 300 DPI is asking for a blurry result. A lesson learned the hard way when I approved a design for a trade show banner that looked fine on screen but was pixelated in person.

Checklist action: Right-click your placed images and check the effective DPI. It should be 300 or higher at the final print size.

Step 4: Verify Text, Proofread, and Set Overprint

This step sounds obvious, but it's the one most people rush. Here's the sequence I follow:

• Spelling and content: Read every word. Out loud if possible. I missed a typo on a product label once. It was embarrassing.
• Fonts: All text must be converted to outlines (curves/paths) or embedded in the PDF. If you don't, the printer's system may replace your font with something random.
• Overprint preview: In Adobe Acrobat, go to Advanced > Print Production > Overprint Preview. If white text disappears, you have an overprint issue. This is a silent problem.

Between you and me, I barely understood this step for the first two years. I just submitted PDFs and hoped. Now I run a dedicated preflight check. The surprise wasn't that fonts could be missing. It was that the printer's system would substitute them without telling me.

Checklist action: Convert fonts to outlines. Run Overprint Preview. Read everything twice.

Step 5: Order a Sample or Proof (Do Not Skip This)

This is the most expensive step to skip. I still kick myself for my third mistake: I approved a $2,400 order of boxes without a physical proof. They arrived, and the color was completely wrong. The vendor couldn't provide a proper invoice that matched the revised specs. Finance rejected the whole expense. I ate the cost out of the department budget—still have a box in my office to remind me.

For custom jobs, always order a proof or sample. Some vendors charge for this (usually $15-$30). Some waive it for larger orders. The cost of a physical proof is cheap insurance. A digital proof isn't a substitute—monitors vary. I've seen a proof look fine on a calibrated screen and print completely differently on actual stock.

Never expected the budget vendor to outperform the premium one on color consistency. Turns out their process was actually more refined for our specific needs. But I wouldn't have known that without the proof step.

Checklist action: Before you approve the final production, request a physical sample. Compare it to the digital file. Sign off on the physical sample, not just the screen.

Final Note: The 5-Minute Rule

The 12-point checklist I keep on my wall (printed by Gorilla, naturally) has saved us an estimated $8,000 in potential rework. Five minutes of verification beats five days of correction. Better than nothing.

My experience is based on 150+ orders with domestic vendors across labels, boxes, and promotional print. If you're working with international sourcing or specialty finishes, the steps may vary. But the core idea—verify before you submit—is universal.

Don't hold me to this, but following this checklist has reduced our reprint rate from about 1 in 5 orders to maybe 1 in 20. Do with that what you will. But I'd start with Step 1.
