Having trouble dialing in those exposure times? This calculator is an easy way to ensure you're getting the proper exposure times. The size of this is 1/2" x 3 3/4" so you can place it on your screen while exposing your image without it interfering. 

How to Use:

Place the calculator on the screen as you would your regular image. And run the exposure time you think is correct. When you wash out your image, you want your step to have 7 solid steps left. 

Don't know where to start? Try plugging in these numbers go from there:
Pre-sensitized emulsion with 500watt halogen light.
Try starting with 10 minutes.
2 part diazo emulsion with 500watt halogen light.
Try starting with 15 minutes.
Pre-sensitized emulsion with multiple uv fluorescent bulbs.
Try starting with 3 minutes.
2 part diazo emulsion with multiple uv fluorescent bulbs.

Screen Press Direct - Solid!

I had the most surprisingly pleasant and helpful experience with their customer service rep, Lou. I called to check on delivery, and voila, order was right on time. I had some confusion on my order as there were various items, and he took the time to go through every single detail with me. I highly recommend Screen Press Direct!
