胶头太软,或是胶头太平没有弧度,字压印在胶头的高处。图案面积太大没有挂网点。还有油墨品质不好,可适当的加点消泡剂
出现这种情况有两种可能,一:胶头有问题!二:油墨有气泡,在油墨中加入消泡剂就行了!
我是做丝印、移印油墨的
My summer vacation of this year was very enjoyable. I went to the countryside to spend my summer holidays. It is very beautiful there. There are green plants, clear rivers, lovely animals kind people. I spent two weeks helping my grandfather do some farm work there. I wrote down what happened in my diary every day.Besides that, I helped the children in the neighbourhood with their lessons. I helped them read English improve their spoken English. Their parents thanked me for this.
