| Problem |
Reason |
Explanation |
| Hairline horizontal banding (<0.5mm) or ‘fuzzy’ text |
Poor nozzle alignment |
Check the test print for each colour and run a nozzle clean if necessary. Solid colours should print solid! |
Fine horizontal banding
(1 - 8mm at consistent spacing) |
Incorrect profile or incorrect media calibration settings. |
Check the profile. A function of too much ink too fast, ie: block colours on high speed settings. Check the media calibration. Try printing uni-directional, to prevent over/underlap of the ink pass resulting in consistent dark and light bands, spaced at the width of the ink pass. Exaggerated at each side of the roll when printing bi directional. |
| Wide horizontal banding (Approx 100 to 300mm at edges of print) |
Media bruising. |
This appears as watermarks, generally at the edges of the roll. Caused by the media being rested on the aluminium bars (which sag and hence put more pressure at the ends) or stored on its side. See pdf below |
| Other Horizontal banding |
Printer head issues, issues with image file |
Possible colour drop out. See pdf below. |
