Question:
I have a Colorsun model DTF printer, and my white ink isn’t consistent. After shaking the ink and thoroughly cleaning, the first two or three prints look solid, but the white ink weakens by the fourth or fifth print. I have to clean the printhead again and use a cleaning solution, but the cycle repeats. It’s frustrating. What could be the issue?
Answer:
Based on your description, it sounds like there may be an issue with ink flow, particularly for the white ink supply. Here are two recommendations to improve your setup:
First, I strongly suggest rolling your white ink before each printing session. Shaking the ink alone isn’t always enough to keep the pigment evenly distributed throughout the ink tank, leading to inconsistencies. I have a video showing how to retrofit a rock tumbler into a DTF ink roller, which can be a game-changer for maintaining even ink consistency. You can check it out here: DTF Ink Roller Video (https://youtu.be/khto7DkPKyg).
Second, consider adding a secondary ink tank closer to the printhead. Your printer’s current setup might be struggling to supply enough white ink during extended print runs, causing the printhead to starve for ink. A secondary tank can help stabilize the ink flow and reduce the frequency of cleanings, keeping your prints more consistent over longer runs.
Addressing printer issues can be a complicated affair due to the hands-on nature of the problems. So, we cannot provide remote troubleshooting, suggestions, or support for printer repairs.
