I have been using these fine-micron stochastic screens both for my work and in the workshops I teach with the polymergravure process for the past year. Available in three screen resolutions, they produce a full range of tones and contrasts: Fine (the softest contrast), Medium and Coarse (the hardest contrast).
If necessary, the screens can be cleaned with a soft cloth and film cleaner (PEC-12) or isopropyl alcohol.
Larger sizes are available - email for details.
Screens are shipped within the U.S. using USPS Flat Rate Priority. Please email me for international shipping options.
