Low-Resolution Images

Overview

Low-resolution images remain one of the most common reprint drivers in commercial print. The failure mode is simple: too few pixels for the size on the page, so edges look soft or blocky once ink hits paper. Screens forgive this; close-view print does not.

The useful skill is not yelling “needs to be 300 DPI.” It is measuring effective resolution at final size, judging subject and viewing distance, and communicating a specific fix: supply a larger original, shrink the placement, or approve the risk in writing.

Many low-res problems begin upstream — web-downloaded logos, social media exports, or screenshots pasted into layouts. Preflight catches the symptom; education prevents the next file. For the deeper math and thresholds by product type, read the print resolution article.

When only some images fail, isolate them. Rejecting an entire catalog because one 2-inch icon is soft trains customers to ignore your warnings.

Step-by-step

1. 1. Locate the flagged objects

   Use preflight or Production Assistant to list images below threshold with page numbers and effective PPI. Screenshot evidence helps non-technical customers.

2. 2. Judge severity in context

   A soft background texture differs from a soft product hero or logo. Prioritize customer-facing brand elements.

3. 3. Offer concrete remedies

   Request the original camera or vector file, reduce placed size, or switch to a vector logo. Avoid “enhance” upsampling as your primary advice.

4. 4. Set a waiver path when needed

   If deadlines force proceeding, document that the customer accepts softness. Attach the PPI evidence to the job jacket.

5. 5. Prevent repeats in templates

   For recurring clients, add image requirements to their intake kit and InDesign package checklist.

Common mistakes

• Upsampling and calling it fixed. Interpolation can silence a preflight rule without restoring detail. Do not treat that as a quality fix.
• Only checking cover images. Interior product shots and maps are frequent offenders. Sample multiple pages.
• Vague customer emails. “Images are low res” without page, object, and PPI evidence invites debate. Be specific.
