"He who marches out of step hears another drum." ~ Ken Kesey
Are you saying 6-8s (seconds?) on exposure?If not, I'm missing something.I use cryocoat (1 - 2) and my exposure times on a 6 blacklight bulb Lumitron unit takes me 2 minutes and 30 seconds.
Slime is definitely an indication of insufficient exposure. Many here have stated that they figure the coating is too thick. I am not too sure of this as I would have a hard time coating only 1/1 and having too thick of a coating without also having quite a mess. With the round side, I would find myself generally using two coats on the print side, and then one to finish on the inside.Of course, for plastisol, I use the glisten method to help me almost automatically get the optimum EOM on any mesh count. And, of course, practice helps.Our newbie friend would be well advised to read the article about this on the home page. http://www.theshirtboard.com/index.php/topic,2621.0.html. There is also an article about exposure.In fact, any newbie would be well advised to read any article there. Old, but still holding much validity, and good background. (Also, we may lose this page when the complete update takes place)As has been mentioned by others, questions are fine, but newbies are all advised to read, read, read. Take advantage of the years of knowledge stored here.

Thought it was because of my weak exposure unit not exposing all the way to the back/ink side of the screen.
Thanks guys. I coated a bunch of screens with diazo yesterday. I used the sharper edge this time and did a 1:2. I wish i waited til I read this, I would've done a 1:1 with the sharper edge seeing that everyone is stating my coat is too thick, but I thought the EOM would be too low if I did a 1:1 with the sharp edge. Maybe a 1:1 with the round edge would be perfect? I will also keep in mind to put less pressure to apply less emulsion moving forward. Let's see how it goes.Thanks guys
