Trying to Figure Out What I Am Doing Wrong
Posted: Mon Oct 08, 2018 10:41 pm
Hello Jonathan and All,
I recently got into screen printing. Up until now I've mostly cut vinyl stencils for smaller less intricate jobs but it's definitely a pain for detailed ones, however, the results have been perfect for what I've needed. Now that I have a more intricate job, I need to do an exposure.
I have this presensitized emulsion and did a 1-4 minute step test and had some issues with blowout. It's that HXT blue presensitized stuff. I have an exposure unit with 4 bulbs (one of those Lincoln ones) and adequate pressure. Everything done in a light safe environment.
The manual says 2 minutes should be good. All screens were coated and left to dry for 24hrs. 160 mesh coated 1:1. Washed out with cold water medium pressure from hose on flat.
Thank you all in advance for any insight you could provide. I have attached a photo of my attempt at the step test.
