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.

    Spot On.

    I recently switched to the DC Pink emulsion and this thing helped me dial in exposure time. I got a solid 7 on my second try. I knew I was right on the money. Shipping was super fast and early even in the middle of the holidays. I now buy all my supplies from direct. Super happy.

    Not for me... yet

    I've seen miracles spoken of this exposure calculator for dialing in exposure times. However, it assumes that you are printing your designs on transparencies with ink. I haven't made the investment in a good photo printer yet, so I'm still printing on vellum with my old laser printer. If I use the exposure calculator with that, I end up with very overexposed screens because the toner lets way too much light through. Once I step up to ink on film, I'm sure this will be incredibly useful.
