Ulano LX 892 emulsion holds up very well under strenuous shop conditions. Ulano Low Cost EZ-FILM™ for Plastisol. The factors that effect exposure time are the thickness of the emulsion or capillary film coating on the screen, chemistry of the emulsion/capillary film, manufacturer of the emulsion/capillary film, and color of the mesh. Ulano Orange exposure time. 3) more uv light means faster exposure. Any my answer is, That depends. I felt like reclaim was tough.
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. EZ-FILM-50 (50 microns) is recommended for use with mesh counts ranging from 86 - 196 threads/ inch (33 - 77 threads/cm. Pink Color - Ulano QTX Screen Printing Emulsion is a ready-to-use, ultrafast-exposing SBQ photopolymer direct emulsion formulated for imprinted sportswear applications. For example, if the exposure time determined with the EXPOSURE FILM & RESOLUTION FILM was 100 seconds, the optimal exposure time is likely to be slightly above or below that time. Ulano FX88 and Diazo is an abrasion resistant, general purpose emulsion for use with solvent based poster or enamel inks. Also, the exposure time is shorter. If you were burning in 18 second increments, the correct exposure time would be 126 seconds (18x7=126). or 0.
Thick Emulsion Build-Up PFX HV, Tex Coat HS QTX Stainless Steel Wire Mesh Tex Coat MSP-2 * These SBQ-Photopolymer's can be made water resistant with the addition of diazo for long runs.

Ulano Orange Emulsion - Quart- Ulano Orange is a ready-to-use SBQ-photopolymer direct emulsion formulated for imprinted sportswear printing. 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.
Just pick the one that washes out the best and there ya go. For those who are comfortable using emulsions and understand the exposure time, pure photopolymers or dual cures are the way to go. EZ-FILM is intended for standard textile printing, and priced to be an economical alternative to direct emulsion in material cost and because it offers significant savings in labor and production time. Take a Step Wedge Test to determine the optimum exposure. My exposure time for a 6. After each coating, rotate the screen 180°. This reusable test should be used any time you change your emulsion, coating thickness, films, or exposure lamps.
