Our screenshots for training materials export at 96 DPI from our LMS. Will this fix print vendor rejections?

Yes, if the pixel dimensions of the screenshots are sufficient for the print size. Correcting the tag to 300 DPI resolves the metadata mismatch. For screenshots, verify that the pixel width divided by 300 gives you the required image width in inches in your layout.

Does correcting DPI affect how images render in our digital course files?

No. DPI metadata is ignored by web browsers, LMS platforms, and PDF viewers for screen display. Correcting the tag only affects print interpretation.

We update training materials frequently. Can we batch-process updated images each time?

Yes — upload multiple updated images in a single session and apply the same DPI value across all files at once.

Our diagrams are built in PowerPoint and export at 96 DPI. Is the pixel resolution usually sufficient for print?

PowerPoint's default export resolution is typically 96 DPI at screen dimensions, which often yields insufficient pixels for print-size diagrams. Use PowerPoint's high-resolution export settings to increase the output pixel count, then use Deliteful to correct the DPI tag on the resulting file. Consult Microsoft's documentation for your version of Office to find the correct export resolution setting.

Prepare Instructional Images at the Correct DPI for Print Workbooks and Training Materials

Instructional designers and curriculum developers exporting screenshots, diagrams, and illustrations from authoring tools routinely produce files tagged at screen resolution DPI — which causes print vendors to flag materials as low resolution before a single workbook is produced. Deliteful corrects DPI metadata on instructional images so print runs go to production without revision cycles.

Curriculum development workflows pull images from a wide range of sources: screenshots from LMS platforms, diagrams built in Lucidchart or Miro, illustrations exported from PowerPoint or Google Slides, and scanned handwritten materials. Each tool applies its own default DPI tag, and almost none of them default to 300 DPI. When these images are assembled into print workbooks, facilitator guides, or compliance training binders and sent to a print vendor, the mixed and incorrect DPI metadata creates preflight failures that delay production — particularly frustrating when materials are tied to a scheduled course launch.

Deliteful processes PNG, JPEG, and WebP files with a metadata-only DPI write, meaning the instructional content — the diagram labels, the screenshot UI elements, the illustration details — is pixel-perfect after correction. For curriculum teams without in-house graphic design support, this eliminates the need to route images back through a designer for re-export every time print materials are updated.

How it works

1
Collect images for the print run
Gather screenshots, diagrams, and illustrations from your authoring tool or shared asset folder.
2
Upload to Deliteful
Add the image files to the DPI adjustment tool.
3
Set 300 DPI for standard print workbooks
Enter 300 DPI — the standard for offset and digital printing — or the value specified by your print vendor.
4
Replace images in your layout file
Download corrected images and swap them into your InDesign, Word, or PDF layout before sending to print.
