Kevin’s Screen Making
Tip of the Week
The team has been in Las Vegas for The Printing Untied Expo, October 19-21, here is another great tip from guest writer Marty Medvetz.
Emulsion:
“High Viscosity = High Solids.”
WRONG! There are two primary components to photoemulsions, PVAc and PVOH. Emulsion manufacturers can choose each of these with any combination of low or high solids with low or high viscosity. I could make for you a very thick emulsion with only 20% solids. On the other end, I could blend a water-thin emulsion with 60% solids. Conclusion: solids content is NOT a direct correlation to viscosity.

In screen making, multiple variables will influence your optimum exposure times. By controlling what you can, you’ll make better screens. To start, print out this Exposure Guide pdf. Then run step wedge or exposure calculator tests on each of your emulsion/mesh/coating combinations. List each combination with its optimum time in its own row on this Exposure Guide. You’ll then have a more optimum exposure time posted for anyone stepping-in to expose screens.
