How to use when developing:
Step 1
Place your exposure calculator anywhere on the screen. Note: You can use scotch tape to secure it in place.
Step 2
Run the exposure time you think is correct. Don't know where to start?
Try plugging in these numbers and go from there:
500 Watt halogen light
Pre-sensitized emulsion - 10 minutes
Two-part emulsion - 15 minutes
Multiple UV fluorescent bulbs
Pre-sensitized emulsion - 3 minutes
Two-part emulsion - 6 minutes
Step 3
When you wash out your image, you want your step to have 7 solid steps left. If you don't, refer to instructions on the packaging to easily calculate the correct time.

Easy to use. Quickly get the correct exposure timing.I think it's over priced for what it is however there's no one else selling this item.This only comes out when you need to try something new so it should last awhile.(Functional durable) to please A

This thing is invaluable. It's a must-have to dial in exposure time. Do some research (and trial & error if needed) to get yourself in the ballbark, then aim for the seven on the scale. Plenty of Youtube vids on how to use it, too.

This small strip has changed my print game dramatically! It has given me perfectly exposed emulsion (once I got it dialed in). I recommend this to anyone struggling with exposure.

The product makes dialing in the exposure time a breeze. $4.00 for shipping is a RIP OFF. Should not cost more than a postage stamp. It is small and will fit in a envelope. Weight is a few grams. A stamp on it and drop it in the mail box done.

In my shop I tried to use this, but it really didnt help. I had to figure out a diff emulsion for the humidity in Fl & a different exposure unit (def recommend a vacuum exposure unit, nothing else came close) and tried using it again, and it just really didn't help me dial in exposing. I just did trial and error of starting with one exposure time and tweaking the time until I had an actual exposed screen washed out, not under or over. Legit, once I stopped stressing about blowing out a perfect 8, I could figure it out on my own starting from scratch. Also, bolt screens dry with blue shop paper towels(less paper residue left on screen. Think of it like using toilet paper to dry screens when using regular household papertowels). If emulsion residue is on the towels when blotting- it's under exposed & add time depending on amount of residue.
