Calculator-Saati-21 Step Exposure
This is the exposure guide of choice for accuracy,
ease of use and all-purpose application. with the Saati
guide, there is no guesswork or complicated interpretation.
it is a more precise tool than the gelatin/density type
exposure calculators, and unlike competitive products, it
can be used on all stencil types and all mesh counts.
(other exposure guides are not compatible with pure photopolymer stencils, and do not perform as well on coarse mesh.)
Our 21-step guide is also much smaller (1⁄2” x 51⁄4”), that it
can be used on all production screens. the Saati Sensitivity
guide is a film containing a transmission type density scale
with 21 steps ranging from transparent to opaque.
(1 = zero density. 21 = solid black.)
Place the Saati 21-Step Sensitivity guide on the screen when exposing. Optimize your exposure so that when washing out the image, you are left with 7 solid steps.
