At a glance
- Start with ink type and coating.
- Check the printing face and media settings.
- No fixed drying time applies to every setup.
Describe the smudge before adjusting
Observe whether the defect appears on exit, on touch, after turning or only where a roller passes. A mechanical streak, a still-tacky area and a stacking mark do not necessarily have the same cause.
Stop the batch and keep a reference sheet with its paper, driver media type and quality. Do not try to rescue a print by rubbing a wet area; that removes useful comparison evidence.
Check ink and the correct face
Reread the paper specification and every cartridge’s ink type, including black. Semi-Gloss and Gloss are dye-only. If a hybrid printer uses pigment black on that coating, changing only the waiting time does not validate the combination.
Also check the intended printing face and media condition. A sheet’s holographic and matte faces are not interchangeable; a marked, damp or contaminated surface can make the result harder to interpret.
Compare one setting at a time
When ink and media are permitted, driver media type and quality are the next checks. Use a small image with text, black and colours. Change neither artwork nor several parameters at once.
Leave the sheet flat without stacking printed faces. Check a waste area for no ink transfer before the back, cutting or sleeving. If the defect persists, keep observations and seek advice for the exact combination rather than continuing the batch.
Questions about this guide
Must I wait a fixed number of hours?
No universal duration is validated here. Follow media instructions and check actual drying; an unsuitable ink combination still needs correcting.
Will an ICC profile remove smudges?
It does not replace checking ink, coating and media settings. Resolve drying before working on colour accuracy.
