Screen Printing Chemicals – My tip of the week is about properly applying chemicals in the screen print shop. This is a very simple but very effective tip. By effective I mean both easier and saving dollars. And I must credit 2RG’s friend Dave Gehrich from Atlas Screen Supply with this suggestion. Dave is a chemical guy and he knows his stuff, so pay attention! When applying chemicals such as press wash, most users will fill a shop rag with chemical and wipe the screen. By spraying the chemical directly on the screen, squeegee onto a rag shirt or pellon, and then wiping, you’ll use a fraction of the chemical.
