We have recently noticed pinholes in our screens. Not entirely sure how long it has been going on, because they are so incredibly small. We haven't actually had any ink going through them, but they are EVERYWHERE.
They show up after drying, but before exposure, so it is not a film or exposure issue. We dry our screens horizontally, print side down, in a cabinet with a dehumidifier and filtered airflow. We have tried two different emulsions and different scoopcoaters.
We are in Richmond, VA and it is very humid here. Could this be the problem?
We usually coat 1and1 or 1and2 because we print a lot of detailed work.
