Hi! If you don't have a Donut Probe then you learn to extrapolate data and do more testing to find what reflective temperature read equates to full cure. Hopefully with the data shown in the video you will have a stronger starting point for your testing.
When we gel the ink under the flash for an underbase, is it supposed to still come off your finger a little bit? Every time I do it to where it doesn’t come off, it ends up being over flashed. If I leave it a bit wet, then I’m fine. S
270° - 280° for 20-30 seconds. Light to medium pressure. Wash test to confirm. You can test for lower temps, but always perform a wash test to confirm cure has been reached. Heat absorption should happen at 270° for 20 seconds, but not all heat presses show temp the same and re-heat at the same rate. Does that help?
Hello there. Yes, a flash dryer is used to flash inks or can be used to fully cure. When dealing with 100% poly, you will want to use either a low cure ink or a poly specific ink in order to combat the dye migration that happens when printing on polyester garments. Hope this helps! Please reach out to us via phone or through the chat on www.screenprinting.com if you have any other questions. Thanks Nick from Ryonet & www.screenprinting.com
Hi @Tammy Saldana. if you are referring to the tee that Colin is wearing in the video. I believe that tee is a print he did for internal testing. If you wondering about the blank, it most likely was an Allmade blank. hope that helps.
"I'm going to demonstrate with both of these flashes, the difference between power output, how fast things come up to temp, and how stable, how quickly things become stable [...]" ... but you only demonstrated on one of the flashes. 🤔
