The Stouffer 21-Step Transmission Sensitivity Guide #T2115 is heralded around the world as "the screenprinter’s choice" for establishing proper screen printing emulsion exposure. It serves as a gauge to evaluate the variables encountered in the exposure and processing of lithographic plates,photopolymer plates and photographic materials by contact. It indicates the direction and magnitude of exposure or processing adjustments necessary toachieve the desired results. It is also used with contact positives, silkscreen, printed circuit boards, and most other photographic applications for judging results, determining speed and contrast of emulsions, and hardness of coatings.

There are many different ways to expose screens. There are an abundance of different exposure systems and processing techniques. Bulb selection, bulb configuration, temperature, bulb distance from vacuum table, glass quality, and the color of the vacuum table all play a pertinent role in determining the correct exposure time required for processing a desirable screen.

The one constant is the Stouffer 21-Step Transmission Sensitivity Guide. Use the Stouffer21-Step Transmission Sensitivity Guide as a benchmark for all exposures to achieve accuracy and repeatability.
