Software Problems
Suspect software when the PNG is valid but changes after import, export, RIP processing, or transfer between applications. Test the same untouched file in a second color-aware viewer before modifying it.
Software diagnosis
| Symptom | Likely cause | Check | Correction |
|---|---|---|---|
| Imported size is wrong | Units, resolution metadata, or automatic scaling are interpreted differently | Compare imported dimensions with the PNG pixel dimensions and intended physical size | Enter final dimensions explicitly and disable unintended fit or scaling |
| Colors differ between applications | Different profile, gamma, or color-management behavior | Inspect embedded color information and application policies | Use the requested profile and align the color-managed workflow |
| Transparency becomes black, white, or opaque | The application, export mode, RIP, or preview does not handle alpha as expected | Test the alpha channel and composite over known backgrounds | Use a supported import path or intentionally composite to the required background |
| Fine gradients show bands | Bit-depth reduction, indexed-color conversion, or output screening | Compare the source, exported PNG, RIP preview, and physical result | Avoid unintended palette reduction and use the validated output mode |
| Artwork is clipped | Export bounds, artboard, page, or printable area is smaller than the artwork | Compare canvas and job boundaries | Correct the export area or production page setup |
| Cut contour is missing | Software imported only raster pixels | Check for the separate vector path and contour naming rules | Associate the required vector contour in the production workflow |
| Software rejects the PNG | Unsupported dimensions, bit depth, animation, profile, or file structure | Compare the file properties with the software specification | Create a compatible production export from the source without discarding required quality |
