I’ve shipped thousands of prints over twenty years, and I can tell you exactly when I started losing money on them: when I stopped treating print preparation as a critical business process.

Early in my career, I’d hand off files to labs with minimal thought. Some prints came back perfect. Others looked muddy, colors shifted, blacks turned purple. I blamed the labs. Then I blamed my camera. The truth? I wasn’t preparing files properly, and that cost me credibility and cash.

Here’s what I learned the hard way, and what every photographer serious about print sales needs to know.

Color Management Isn’t Optional—It’s Insurance

Your monitor lies to you. Mine certainly did until I calibrated it properly.

I use a ColorLogic display calibrator monthly. It’s non-negotiable. Without it, you’re guessing at what your prints will actually look like. A $300 calibrator pays for itself after three bad print runs.

Beyond your monitor, you need a working relationship with your lab’s color profile. Request their ICC profile directly—not a guess, not “standard sRGB.” Real labs provide specific profiles for their paper stocks and processes. Load them into Lightroom and Photoshop. When you soft-proof using their profile, you’re seeing what the print will actually deliver.

Most of my color issues vanished once I started soft-proofing every single image destined for print.

Resolution and Sizing: Do the Math Before You Commit

This is where I catch mistakes daily from photographers I mentor.

You need 300 DPI for any print larger than 5x7. No exceptions. If you’re delivering 8x10s, that’s 2400x3000 pixels minimum. Working backward from a client’s requested size prevents the embarrassing conversation about why their 16x20 looks soft.

I use Photoshop’s Image > Image Size dialog. Set it to 300 DPI, check “Resample” with “Bicubic Sharper,” and size accordingly. Upsampling from lower resolution is acceptable only up to 10-15% enlargement—beyond that, you’ll see degradation.

Create a checklist. I literally have a printed sheet next to my desk listing common print sizes and their required pixel dimensions. Sounds obsessive? It prevented a $400 reprint last month.

Sharpening Happens at the End, Not the Beginning

This is the workflow mistake I see most often.

Don’t sharpen in your main Lightroom catalog. You’ll over-sharpen for screen viewing and under-sharpen for print, or vice versa. Instead, create a separate export preset specifically for prints. In Lightroom, under “Output Sharpening,” I select “Matte Paper” or “Glossy Paper” depending on the finish, and set the amount to “High.”

Then—and this matters—I do a final pass in Photoshop using Unsharp Mask at 1.2x radius, 0.8 amount, 4 threshold. It’s subtle but catches microcontrast that print labs appreciate.

Soft-Proof Everything Before Sending Files

This is the step that separates professionals from hobbyists.

In Photoshop, go to View > Proof Setup and select your lab’s ICC profile. Make it your default. Any color shifts you see now will appear on the actual print. If your image looks worse under soft-proof, your file preparation isn’t finished.

I often find that a subtle bump in saturation or a slight S-curve in Curves solves what soft-proofing revealed. It takes an extra fifteen minutes per image but prevents shipping files that disappoint.

Build Redundancy Into Your File Naming and Organization

Here’s the pragmatic part: you’ll lose files. You’ll overwrite things. You’ll send the wrong version to a lab.

I save print-ready files in a dedicated folder structure: [YEAR]/[CLIENT]/[PROJECT]_PRINT_FINAL_[DATE]. The “PRINT_FINAL” tag reminds me this file has been color-corrected, sized, and soft-proofed. It’s gone through the gauntlet.

Before uploading to any lab, I take a screenshot of the soft-proofed image on my calibrated monitor. I attach it to the order notes. When the prints arrive, I compare. Discrepancies mean I can address them immediately rather than reprinting blindly.

The Real Payoff

Tight print prep workflow means your prints match your portfolio. Clients notice. They order more. They refer. That’s how you build a sustainable business.

Stop leaving quality to chance.
