There are a lot of variables that go into exposing a screen for screen printing. The opacity of your film positive, your emulsion, the type of exposure unit you’re using and even the age of your exposure unit all will affect the amount of time you need to expose your screens and the success of your stencil.

Before you can create high quality prints, you have to create high quality stencils. However, this is often easier said than done. There are many, many variables that go into creating the right stencil for the job, and some of these factors are easy to overlook. First, you need to right emulsion, then you need to apply it correctly.

Most screen prints involve laying down simple designs with finite borders, one color at a time. But every screen printer has to deal with more complex prints from time to time, whether it’s a four-color process job or a print with gradient tones for special effects.
