Uv printer hit pvc board why a scraping off
Before the scraping is very good scraping off, and now a nail plan, plans to fall out
I have found this problem. It is estimated that you buy is to strengthen the hardened PVC board, the recent market there have been. This PVC board surface is very hard, pinch and draw with nails can not get printed, resulting in UV ink with the combination is not very good. Before the market flow of PVC foam board surface density is relatively small, playing to the firmness is very good.
The solution to this problem is very simple to treat him as a print glass, before wiping the glass coating before printing, the firmness is quite good. Of course, if you use UV printer to print ordinary PVC foam board, you can not do any pre-treatment.
Can be analyzed from two aspects:
Ink and coating problems (this can only be resolved through the sale)
PVC board problem (this can ask the supplier, the board and before there is no difference, because the higher the density of printed materials, UV ink adhesion worse)
Uv printer hit pvc board a scraping off, the reason for the two:
1, uv ink itself is not very good quality, need to replace the new ink;
2, led light curing device power is not enough, need to improve.
In addition, some are also affected by air humidity.
