This small, light weight portable spectrophotometer is designed for easy operation and high precision for a variety of functions. It measures the wavelength and output interval of light sources in your screenmaking area - both the exposure equipment and ambient lighting

SAATI’s 21 Step Guide is a day one priority for every screen printer across every application. This small tool is applied to the stencil material prior to exposure, and when developed tells you whether the stencil has over or under exposure, or is dialed in for the best print quality. Count the number of progressively darker steps of the calculator that have adhered to the mesh, and make one simple calculation to prepare a second test and confirm perfect stencil curing.

Take it one step further and apply the calculator to every screen you produce - you will know with certainty that every screen going to press is dialed in for high resolution and durability.

This handy guide is fixed to emulsion prior to exposure and upon developing reveals resolution and definition for 4 progressively shorter exposure times – 70%, 50%, 33% and 25% of the actual test. Compare the results between steps to make an informed decision about what result matches your exact needs.
