Quality Control Devices

Yellow LED Safelights permit you to brightly illuminate the areas where you store, transport and prepare screens for exposure. With a light “airlock” it’s possible to work comfortably without compromising stencil quality. SAATI Yellow LED Safelights are the preferred solution

Safe light goggles are an essential tool for every screen printing business. Safe light goggles ignore the wavelengths that are safe for unexposed stencil material and only allow the wearer to see in the wavelengths that do affect them. Instantly verify the presence or absence of unsafe light wavelengths in the areas where you store, transport and prepare to expose unexposed screens, so you can take decisive action with Safe lighting as needed.

Accurately count the number of threads per inch within +/-2 in mesh counts ranging from 22-528 TPI.

This is accomplished by placing one of the 2 included films (22-276 TPI and 274-528 TPI) onto your fabric and rotating the film until the moire pattern appears next to the mesh count.

Confirm the tension of your mesh during stretching, and at all subsequent stages to avoid printing with under-tensioned screens

The ISPS Thread Direction/Mesh Angle Gauge is a quick and easy way to reference the mesh angle on any screen, eliminating the guesswork caused by unmarked screens especially in 4-color process printing. In addition, the gauge is very helpful in diagnosing moiré issues caused by screens or films. Can be used on both coated and uncoated screens, as well as film.

Use gauge by laying it directly on the screen or film. A moiré pattern appears on the tool at the angle it sees.

The only analog tension meter in the world with all stainless steel hardened gears, and shock-proof industrial-grade internal gear movement

Use this digital gauge to measure the EOM of your screens prior to exposure so that your exposure program and eventual ink deposits will be correct

Use this digital gauge to measure the EOM of your screens prior to exposure so that your exposure program and eventual ink deposits will be correct

Use this digital gauge to measure the peaks and valleys of your stencil surface to understand if the surface is too rough or too smooth to create precise ink deposits

When diazo/dual-cure stencils are moist and are exposed in that condition, they suffer from loss of resolution, and any moist screen can also stick to vacuum glass. With a Moisture Meter, it is simple and quick to confirm that a coated screen is fully dried before subjecting it to an exposure program.

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.

A compact and simple to read tool that confirms squeegee hardness for blades without a stated value, it also helps you identify squeegee that have softened, so you always go to press with the right blade for accurate printed results.

This powerful handheld microscope allows you to check your halftones on substrates, to check whether details have narrowed or closed prior to printing, and to check the quality of the edge definition with up to 200x magnification
