Tips for Applying Emulsion During Screen Printing
A very important part of the screen printing process is the application of a chemical substance known as emulsion. It is an element that is light sensitive. It hardens on a screen and helps to block ink from passing over the screen and coming into contact with a printed medium. Emulsion creates a proper coating for allowing clean work lines. Emulsion must be correctly and evenly applied for it to work as it should.

There are some suggestions to aid in creating a proper screen using emulsion in the following.

• Be sure to use the correct type of screen for emulsion and the item to be printed. Make sure the screen is tightly stretched as well. A tighter screen will allow for the best printing and consistency in the printing.
• Always mix emulsion two hours before it is to be used. This allows time for any air bubbles caused during mixing to bleed out. If not, there may be pin holes left in the screen.
• If decreasing is needed, use a degreaser.
• Only coat a screen that is thoroughly dry.
• Use a scoop coater to coat the material facing side and a squeegee for the other. Each side will need only one single coat.
• Dry screen with t-shirt or material side facing down.
• After screen is dry completely, printing may begin.
