What's up Tee Shirt World

I'm pretty new to the screen printing world. I've had experience here and there, but to the process as a whole, it's a new challenge.
I'm currently in the process of figuring out the whole emulsion process. I'm having troubles with exposure times and the emulsions breaking down during printing. Hoping that will change when I up the exposure times. Also, I am working on specializing in water based and discharge inks so I think that might play into the emulsion dissolving.

Otherwise, I'm just a little shop on the island of Nantucket. I'm specializing in a high end retail brand, Grey Clothing Co.
I'm redoing the website www.greyclothing.co but it will be up in the next month or so.
I am also on instagram, twitter and tumblr as greyclothingco
feel free to follow and I look forward to following back!

This is a crazy learning experience and I'd love to help when I can and accept it when I'm about to pull my hair out.

Welcome to the forums, as well as the screen printing world!

Here's a few pointers on exposure times:

- If you're using a fluorescent light exposure unit, then I recommend about 2 minutes 30 seconds for exposure time.

- If you're using a metal halide unit, I usually do about 30 to 45 seconds.

Exposure time can also vary depending on the type of film positives you're using - if you're using transparencies, the above times should be fine, but if you're using vellum in a laser printer, the exposure time may need to be lowered slightly because too long in the unit, and the sheet of vellum will begin to expose on to the screen. However, back when I was at the first screen printing shop I worked in, we used vellum in a laser printer and I exposed screens for 2:30 all day long with never a problem. Even rinsed them with a pressure washer.

Any questions, don't hesitate to ask! :)
