Q Flaking powder
A Reasons
The blank place powder around the pattern sticks the coating after heat transfer printing
Solutions
May due to the heat transfer printing pressure is too high, which makes the film ink absorbing layer damage peeling or fabric surface size easy to stick the coating. Generally, as long as the temperature and pressing time can meet the requirements of sticking firmly, it can be easily solved when adjust the pressure as small as possible down
-
Q Oily or damp
A Reasons
Baking dried patterns or pasted and transferred patterns become oily and damp
Solutions
It belongs to the phenomenon that the glue is not baked thoroughly, the water and glycerin in the ink cannot be thoroughly baked and then reversed. Generally speaking, single sheet operating version with 120 degrees low temperature for a long time through it best. As powder is limited by the length of the powder machine, so we can try to raise the connected board appropriate high temperature to make the water and glycerin evaporation in advance might also help

Q Powder holes
A Reasons
Ink water and glycerin boiling evaporation with high temperature and short time baking dried, which pulls holes out of the coating and film
Solutions
It' better to give priority to medium and fine powder, a little coarse powder or even no coarse powder, it works best when baking dried in the low and high temperature section for a long time, it works best when baking dried in the low and high temperature section for a long time, it can be gradual to dry oil and water and melt glue thoroughly, but no violent reaction. The resulting film is flexible, elastic, smooth and dry. If the powder machine begins with a slightly poor conditions, it's necessary to make use of the function of preheating chopping board to heat and steam away some water in advance to reduce the burden, dry them then shake powder.

Q Powder shaken unclear
A Reasons
Wet weather, humidity, strong static electricity, it needs to check when the edge of the pattern is unclean.
1、 Whether high humidity or low temperature
2、Whether the strength of powder shaking machine is insufficient
3、Whether the printing interval is too long without powder caused by drying glycerin diffusion
4、 Whether ink misting on heads
Solutions
If it is found that the pressure wheel position or large blank area shaking is not clean, it should be electrostatic influence or powder damp or too fine, you can take measures as appropriate.
Generally, increasing the temperature of the heating board after printing and shake powder machine connected board can reduce the edge powder shaken unclear.

Q Ink flow
A Reasons
1、It becomes easy to flow ink where has powder impurities or crush wounds
2、The heating board is not open after printing
Solutions
If the ink flow is due to the poor absorption, we can try 1, reduce the proportion of white ink setting, appropriate to reduce the amount of white ink 2, increase the temperature of the printer heating board can also improve the pass rate 3, board heating can help ink activation and then reduce ink flow phenomenon
