Gold foil printing process common problems:
① fly gold stamping fine line there is the phenomenon of how to do?
(1) The cold wave, oblique tear.
(2) Select the release layer tight foil paper.
(3) the temperature should not be too high, the low temperature will be better.
(4) The pressure should not be too heavy.
② hot out of the color, dark or blue-emitting how to do?
(1) should pay attention to control stamping temperature, if the temperature is too high, easy to produce mist, paste version, brightness difference and blistering and other ills.
(2) selecting the stamping pressure and time, pressure and heat press machine each time has deviation, flexible commissioning.
③ stamping effect how to do good flatness
And bronzing pulp constituent, about the thickness of a hot melt powder, the finer powder particles melt, flatness better; printing bronzing pulp dry nor too flat, to grasp the rare dryness.
④ not washable, easy to fall off how to do?
the reason:
(1) whether the wrong gold foil paper
(2) gold foil paper and bronzing pulp does not comply
(3) temperature or pressure is not reached
Solution:
(1) Replace foil paper
(2) Replace or bronzing pulp gold foil paper
(3) to adjust the temperature, pressure
⑤ hot when there is a blank spot large area or have trachoma how to do?
(1) Pressure uneven mattress; increase the pressure or temperature adjustment.
(2) bronzing pulp does not brush well, adjust the printing process.
(3) bronzing pulp is too dry, the printed often enough; bronzing pulp is not thick enough.
⑥ Quebec to washable good performance, good gloss, smoothness and smooth?
The correct manner, master temperature, pressure, time, high-quality pulp and foil paper bronzing.
⑦ when folded flat hot foil paper
(1) The paper is not tile well.
(2) the pressure is too heavy, the appropriate debugging.
⑧ flat iron out irregularities (peeling in some places better, in some places stripping incomplete)
(1) heat transfer machine uneven floor, the bottom surface of the pad level.
(2) the pressure is uneven, adjust the pressure (lighter or heavier).
(3) bronzing pulp no good brush, transfer time no master.
