Welcome to the world of screen printing, where achieving the perfect exposure time is the key to unlocking exceptional print quality. In this friendly guide, we’ll take you through the essential steps to help you dial in the ideal screen exposure time for your screen prints.

Utilizing A Screen Exposure Calculator

One of the handiest tools in your screen printing arsenal is the screen exposure calculator. This nifty tool takes the guesswork out of determining the right exposure time for your prints. Simply input details like your emulsion type, mesh count, and light intensity, and voila! You’ll get the precise duration needed for a flawless exposure. No more worrying about under or overexposing your screens!

The Saati 21-Step Sensitivity Guide

Meet your new best friend in the quest for the perfect exposure: the Saati 21-Step Sensitivity Guide. This handy film positive comes equipped with a grayscale strip ranging from see-through to fully opaque, divided into 21 steps. It’s like a roadmap to exposure success!

How To Use The Screen Exposure Guide

Getting started is a breeze. Begin with an initial test exposure based on your emulsion and light setup. Then, after exposure, simply wash out the screen. The steps that wash out cleanly on the guide indicate your exposure level. Easy peasy, right?

Fine-Tuning Your Screen Exposure Time

If you find too many steps washing out, it’s a sign of underexposure. Give your screen a bit more time under the light. On the flip side, if too few steps wash out, you’re dealing with overexposure. Dial back the exposure time a tad until you find that sweet spot.

Factors To Keep In Mind

Remember, not all emulsions and mesh counts are created equal. Adjustments may be needed based on these variables. And consistency is key! Keep your coating thickness and drying times uniform for accurate results.

Documenting Your Screen Exposures

Don’t forget to keep track of your exposure times, emulsion types, and other important details. This documentation will be your trusted guide for future projects, ensuring consistency and top-notch results every time.
