We all want to know what the perfect exposure time is and what we have for you here is the best cheat sheet you will ever get in screen printing.
Achieving the perfect screen print starts with properly exposing your emulsion. The EcoTex Emulsion Exposure Times guide by ScreenPrintDirect breaks down everything you need to know about getting crisp, well-defined prints without under or overexposing your screen.
The exposure time for emulsion varies based on several factors, including the type of emulsion, light source, mesh count, and coating thickness. If the exposure time is too short, the emulsion won’t fully harden, leading to premature breakdown during washing. On the other hand, overexposing your emulsion can cause difficulty in rinsing out the design, resulting in lost details.
This guide provides step-by-step instructions on determining the right exposure time for your setup, along with troubleshooting tips for common emulsion-related issues. Whether you’re using a traditional exposure unit, LED light, or sunlight, the article offers best practices to help you achieve the ideal balance for your prints.
All Ecotex® emulsion exposure times have been tested by us but these are still approximate times. Everyone’s screen printing exposure times can vary depending on how many coats your screen has, how dense your Inkjet film was printed, and so on.
