It's time to step up your game.  Manually coating screens is strenuous, exhausting and often inconsistent. The G-Coat 406 allows your growing shop to eliminate a key variable in the printing process without breaking the bank. Consistent screen coatings allows for consistent stencil thicknesses, consistent exposure times and ultimately, consistent print results.


The G-Coat 406 is a single screen, fully automatic coating machine for both manual and auto press screens. Are you limited on space but still require reproducible results while maximizing your production efficiency? With a small footprint, the G-Coat 406 will revolutionize the way you are able to coat screens and have control over one more variable in your process.


The included stand allows you to work at a comfortable height.  Once it's assembled, the coater is simply "plug & play."
