How To Properly Degrease A Screen

Posted by Dwayne Collins - Outside Sales on 7/1/2013

Degreasing your screen printing screens is a very important part of the screen preperation process. It's important to degrease your screens prior to applying emulsion or film because new screens or re-stretched screens need to be free of grease, oil and dirt to avoid problems with the stencil quality.

Your hands will leave an oily residue while dust and dirt can accumulate during storage. 
Using a degreaser removes grease, oil and dirt from the screen mesh fabric so that the emulsion adheres well.

Degreasing The Screen Process - 

   A. Place your screen into your sink and get it wet.

   B. Spray a small amount of degreaser onto the surface of the screen.   C. Using a white scrub pad, scrub from top to bottom and side to side on both sides of the screen. We recommend Chem 200, or Franmar D-Grease as the degreasing agent.   D. Change degreasing scrub pads often to keep from contaminating your screen and causing pin holes.   E. After scrubing down screen, flood rinse from top of screen to bottom and throughly wash all degreaser off the screen.
   F. If you will be applying Ez-Film or any another Capilary film you may proceed to apply the film while the mesh is still wet.
   G. Don’t touch mesh with your hands after degreasing or set fan in floor blowing onto the screen. Dust and lint can blow through fan and stick on wet screens causing pin holes.   H. If using emulsion to coat the screen allow the screen to dry in a clean, dry environment. It's important to make sure the screens are kept in a clean, dry environment until ready for use.
