We are new to screen printing and we are printing on CDs using Marabu UV inks. When we wash the screens out, a thin haze is left in portions of the screen. This haze is just thick enough to block the screen. It is also fairly random and ends up blocking about 10 - 20% of the open fabric area.
If we rub on the scren long enough (a couple hours) it eventually comes out. If we then re-use the screen then it washes out normally.
We are using acetone as a washout which is recommended by the rep from whom we purchased the ink.
We are contracting out the screen making to another company who insists its not a problem on their end. If anyone has any suggestions as to what may be causing this I would greatly appreciate it.
