Step Wedge Basic Emulsion Exposure Calculator

8 reviews

Our Exposure Guide is the easiest way to ensure durable stencils every time. In a single exposure, this 10-step guide tells you how to adjust your exposure time for complete stencil curing. Measuring only 1/2" x 3 3/4", it will fit on your production screen without interfering with other graphics.


Place the Ryonet 21-Step Sensitivity Guide on the screen. Optimize your exposure so that when washing out the image, you are left with 7 solid steps. If you see only 5 steps, you run the risk of pinholes or premature breakdown, and you should double the exposure time. If you see steps, you will have lost finer detail in the image, and you should halve the exposure time.

I recommend this product
Works like it should!

This has been the most helpful item I’ve brought into my shop. I never realized how much I’ve “under exposed” before purchasing this. Super helpful!!


Thanks Jeff! Yea, I stress getting one of these to every customer I ever talk to about getting a correct exposure time. They are a lifesaver!

Screen Printing Rookie Mastering The Art

I can't tell you how many hours of tutorials I've watched as a newbie! I was initially confused since each screen is different (right?!) but after contacting Ryonet's customer service, I learnt you essentially 'sacrifice' one screen from a batch to figure out your exposure time using this extremely helpful doodad. The directions are a little sparse and expect you to know what some things mean (optimize your exposure *shrug emoji*) but Ryan's 'how-to' video shows how to use the exposure calculator properly. Works great, correction table is accurate. My only remaining comment is put it in a safe spot so you remember where it went, coz this lil' gizmo has an uncanny ability to disappear.

This helps so much to ensure you are getting a proper exposure time on your screens. Every shop should have one! Easy to use and less time and material wasted!

best small investment.

Super simple to use, and has been one of the tools that have made our shop a lot more efficient, as we've been growing our need for efficient consistency has been key and the exposure calculator takes all the guesswork out of it. We use it on every one of our screens, allowing us to keep watch if things like the light potency or film density are changing over time so we can adjust accordingly, so not only has it removed our need for sometimes re-burning screens but it helps to keep a gauge on other supplies/equipment. Only wish we'd bought this sooner

New Printers Need This!!

This is the absolute best tool on the site. So many times new printers don't know where their screen problem is - bad positives? bad coating technique? or bad exposure time?This will eliminate one of the variables for you right off the bat. By seeing what number is the last number to be exposed, you read what the scale on the package says, and you adjust your exposure time accordingly. You'll never need to over or underexpose images again.BUY THIS.
