How to solve the uneven color of printed pictures with DTF pigment ink?

In DTF printing, for the problem of fast printing 4 heads, uneven color of printed pictures, like a “cloud”—especially magenta and cyan color.

1). Key problem is the mainboard control system makes ink droplets not jet in the right place.

Hosonsoft is currently the best motherboard for the Epson i3200 DTF printer, but it cannot avoid this problem, uneven color of printed pictures. So we need whole market technology to improve, we have to wait.

2). Now we have some methods to improve:

A). Use better DTF pigment ink, more fluent, higher density.
B). Use better film, thicker, better absorb. And the coating layer is more uniform, each ink drop absorbed well.
C). Lower the speed.
D). Use more “feather” settings, 40%, 80%, and 90%.

About Epson T3200 and Ricoh G6, we look at the advantages and disadvantages objectively.

Epson T3200 and Ricoh G6 have started fierce competition in the market, but how do we look at the advantages and disadvantages objectively.

  1. Epson T3200 supports 4 colors, 2 colors, can be spliced, 4.8-5PL. Compared with Rioch G6, it can be configured with fewer printheads under the condition of colors and white high-speed printing.
  2. T3200 price is good, the price is about RMB 13000 (USD 1890 ), currently, there are only about 7-10 printer factories (Flora, Docan, GZ, JHF, Liyu, Kingt, etc) authorized by Epson T3200.
  3. Epson T3200’s jetting power is not as strong as Ricoh G5/6, so the printing accuracy is relatively low.
  4. Compared with Ricoh G6, the color of the picture printed by T3200 is lighter, so need more pass.
    One head with 4 colors needs 6 pass, and 1 head with 2 colors needs 8 pass.
    One head with 4 colors (1 printhead), 6pass printing speed is about 16 square meters/h, 1 head with 2 colors (2 printheads) print speed is about 24 square meters/h.
  5. T3200 prints solid color and 100% C, M, Y, and K is flawed, and there is some gap compared with G6 now.
  6. The Epson T3200 motherboard has some BUG current, but I think as the T3200 more and more popular, there will be a better matching motherboard.
  7. Epson T3200 has high requirements for UV ink, and it is not easy to match ink.

EPSON T3200-U3 Details

EPSON T3200 launched in 2021 with 4.8-5PL. Printer brands JHF, Docan, Flora, GZ, etc. have begun promoting flatbed UV equipped with the EPSON T3200.

The EPSON T3200 single-head production capacity is about 15-20 square meters per hour, and it supports 4 colors in one head, which is faster than Ricoh G6. But our technical department said that according to their experience, Epson print heads are easy to fly ink, especially when the temperature is low or the printing height is high. And Epson heads have less jet pressure than industrial heads.
