alternative to using emulsion (coating)

Posted on Wed, 10 May 2006 at 19:28



Does anyone know of an alternative to using emulsion for screen printing small run coroplast signs. All of my runs are 25-200 signs, 1 or 2 colors. Going to the process of purchasing positives, coating screens, drying screens, exposing screens etc. seems a bit much when running 25 2-color signs. Any info would be greatly appreciated.

Why can you not create your own films inhouse? You don't need extravagent films usually for coroplast. I have printed out gradients that look great on coroplast. Of course the dots are a lot larger than normal CMYK.

Coating screens should only take seconds, but do you have a dehumidifier for the drying process. That helps for some people.

How long is your exposure time? Mine is about 140 seconds.

Are some signs designed so you can make one film and tape over the other color to save screens? I have done that for many political/real estate signs. Can you turn the signs another way to fit both images on the screen?

I am new to this forum, and this is my first post, so I don't know what other sugestions you might have received.
