“Weakening of white ink coverage” suggests that the white ink applied during the DTF process is not providing the desired level of opacity or coverage. Here are some steps you can take to address this issue:
1. Check for bends in the white ink tube
Bending of the white ink tubes can lead to poor white ink flow, which in turn leads to poor white ink coverage.
2. Change DTF Printer’s Damper
In addition to the common clogged nozzles, there is also the possibility of clogged dampers.
3. Test Different Films
The type of DTF PET Film you use can affect ink coverage.
Please try different DTF PET Films to find the best match with the machine you are using and the DTF consumables.
4. Replacement with new DTF Ink
After replacing the ink, shake the cartridge slightly (the ink may have been sitting too long).
5. Try changing to another RIP software
RIP software plays an important role in the printing process. It determines the color, screen pattern, and resolution of the final print, ensuring reliable color reproduction. (Sometimes problems with print colors come from incorrect RIP software settings.)
6. Cleaning the print head
The print head may be clogged, or there is air in the tube, etc.
7. The recirculation pump is not working properly
Turn on the circulation pump to check for proper operation.
8. Modify or replace the ICC profile with a different one.
