Start by burning the whole screen 1 minute less than the recommended time for your unit/emulsion. I am not sure if it is meant for wr emulsion. It is formulated with a “masking color” that reduces light scattering—the major cause of loss of resolution. Both are formulated to reduce stencil-making time (coating, drying, and exposure) in shops with high stencil throughput. EZ-FILM is pre-coated by Ulano to a tolerance of ±1 micron (0. EZ-FILM is ideal for mesh counts ranging from 110 - 156 threads/ inch (33 - 61 threads/cm. During exposure time, both of these components will be cured. ** These Dual Cure Emulsions can be made more water resistant with the application of Stencil Hardeners after image development. 328. It's high solids content ( 43%) allows a thick build per coat, reducing the number of coats over conventional emulsions, and facilitates quick drying; its exceptional photo-sensitivity reduces exposure time and will be of interest to low volume printers with weak light sources.


Method 3: Follow Method 2 (above). Louis, George Legh-Page did a Ulano Exposure Claculator Test Tutorial Video. When placed approximately 12" above the screen, this light will properly expose most emulsions in around 5 to 7 minutes depending on distance from screen.

Method 1: Apply one coat of emulsion on the printing side, then one coat on the squeegee side. Ulano Orange reduces stencil-making time—in coating (because of its high viscosity), drying (due to its high solids), and exposure (due to its high photo-sensitivity despite its “masking color. Ulano says the film’s compatibility with wet processing eliminates virtually all pinholes. The filters vary the amount of UV light that gets to the stencil in one exposure so you don't have to take the screen in and out of the vacuum frame every time you want to move the mask. With its manufacturing and corporate headquarters based in Brooklyn, New York, the Ulano corporation is recognized as a world-class leader in the screen printing and graphics arts industry.
