Thickness Gauge???

Ok I bought this thing now how do I use it.

What is the right thickness and what is not?
how do you figure out the percent of EOM?
Is it different on 160 mesh than 230?

Do you guys really use this or is it a play a trick on the new guy thing.

Thanks in advance for the very detailed step by step instructions on how to use this. You really didn't have to spend that much time on it.

Thanks Jon

measure a section of uncoated mesh.  then measure a section of the same coated mesh.  That will instantly tell you how much thicker the stencil is than the mesh.  then take the difference of the 2 numbers and divide it by the thickness of the uncoated mesh.

I use ours all the time.  I tend to shoot for a 12-50% EOM, all depending on what I want the screen to achieve.  Standard 156 mesh being used for plastisol on a regular garment, I'd use a 156 with a 20% eom ratio.  A white print on a black shirt, I'd use something that has a thicker stencil, 30% or even more.  Those percentages I'm throwing out there equal anywhere from 10 micron stencils on higher mesh counts to 200 micron stencils for lower mesh counts used for special prints.

I spent a couple of days scouring the internet for the White papers from the ink and emulsion manufacturer's and could not get a precise answer, but my conclusion was that the sim process should be in 7%-10% range and the spot color work around 20%. There are reasons to adjust these numbers and the best example is the white ink on black that Alan is doing. I have some of his samples and they look great. Since talking to him we started coating our 110's (used for single color white on darks) much thicker and are getting significantly better results than before. Additional contributing factor was the 55 triple duro squeegee in combination with the high EOM stencils.

Thanks guys. I look forward to using this thing. It is always nice to be able to measure what you’re doing so you can correct it. Can you guys post what some of your screens are at. Micron thickness for a few mesh counts?
