Hi recently we have been running into an issue of dtf inks not drying on t-shirts. Specially on black prints, requiring additional 3-4 press (which in some cases helps drying up while some dont)
The print can be smudge with a piece of cloth after doing a double press. While both at luke warm and cold state of the print on the tshirt.
The issue started 1-2days back, We already had done some of the process below to identify the issues (unsuccessful).
1) change the inks (white and colored) completely.
2) used a different powder.
3) Tried different temperature of curing (oven 100-150 Celcius).
We had no problem doing a double press for our previous tshirts and no pre heating of tshirts. We keep at least 30-60 seconds before putting in the powder.
I have been reading the forum posts and keep reading about static and moisture, is that causing the issue (if so how do I solve that issue)?
or is it an ink, powder or film issue (have not tried a new film)?
We have a chinese 24inch dtf printer, while the film is a roll.
Thankyou for any responses
