The Effects of Humidity on Screen Printing

screenAnother recent article published in ‘Printwear‘ by John Levocz. It’s that time of year again when everything in your shop seems to be wet due to high humidity, and this humidity can cause several problems in your shop that you should be aware of.

First, screens will take a lot longer to dry after degreasing and also after coating with emulsion. Do not rush the coated screens. Make sure they are dry all the way through the emulsion coating. If they are tacky to the touch, they need more drying time. Rushing the screens can cause pinhole and emulsion washout issues.

Second, when using plastisol inks, the moisture in the garments need to be driven out before the curing process can start to take place. Shops with smaller dryers and very little airflow can expect to see their cure time increase, so it is important to re-check your cure before blaming the ink.
