Many people told us that print the matt ink on EBG material is not a good way, because of that the adhesion is not good. But usually the membrane keypads need use the EBG material which is anti-scratch. In order to solve this problem and also prove that it can be printed matt ink on EBG material, LUPHI ELECTRONICS did some experiments. Bellow are the details:
We tested 5 different types clear varnish ink on EBG PET material.
UB-1, UB-2, B-15, 09-CL2KG and 09-CL5KG
We found that:
1) The adhesion capability of B-15 is the worst.
2) UB-1 and UB-2 are much better;
3) 09-CL2KG and 09-CL5KG are the best, no any dropping of the ink after did various kinds of testing;
Through UV oven parameters:
Three light tubes be lighted together, rotation speed set 35, pass through twice;
Testing methods: scratching testing, embossing testing and cutting testing
