Re: Need Advice: Paint Not Flowing Through Screen

4) Laid glass over them to hold them down
5) Applied 150W light at 12" for 45 minutes
6) Sprayed it off with warm water
The screen looks perfect. Completely see through on my logo, green everywhere else.
I lay the screen down on the fabric, spread the paint, lift the screen, and NOTHING.
If I press extremely hard, then leave the paint pretty thick across the logo, then it works ok. Anyone know where I screwed up?

You probably have emulsion haze blocking your image open area. If you look at an angle on the bottom of the screen you will see the haze. This can't be removed and you will need to start over. Suggest you thoroughly wash your screen after exposure with med temp water. . both sides, top to bottom. Then dry your screen horizontally with the ink side up. If you dry the screen leaning against something the emulsion will run into your image open areas. I also don't like your double positive idea. If you are using a laser printer go to Home Depot and get Krylon Matte Finish and put a light spray on the print. It will make the print much more opaque. If you are using an inkjet printer, put your print settings to indicate you are printing on Transparency Film at maximum DPI. Regards, . ThePrintinator.Com
