Heat sublimation printing ink at the time of printing, because the plate cylinder presence neutral gear, product ink easily cause phenomenon of front dark rear light.
Cause this phenomenon is because when the ink roller rolls over the plate gap, the inking roller savings portion of the ink, with the inking roller scrolling plate from the bite edge to the tip side, Inking roller first lap the amount of ink will be more than later, lead to the phenomenon of front dark rear light. To solve this problem, we need to adjust the starting point of string roller.
