In Action: Dye Migration Protection With Gamma Blocker Black
When it comes to printing on dark polyester, dye migration is enough of a beast to worry about without adding the complications of printing with thin water based inks. But what about when you want to create bold and bright bright spot color prints?
As usual, there are screen printers out that throw caution to the wind and go for those difficult prints headstrong. Danny Gruninger from Denver Print House falls in that category. He’s always pushing the boundaries of screen printing so that others can learn from his print successes and I wanted to share a recent job Danny attempted on Royal Blue 100% Performance Poly using Green Galaxy Gamma Blocker Black and HSA Water Based Inks.

Speed: “I ran the press myself as I did this after hours one night…I was casually printing 325 pieces per hour with this setup.”
Curing: “With the ROQ Tunnel set to 3 minutes retention time and 311 degrees.”
Final Thoughts: “Gamma has been really good so far, at least 50% longer open times compared to the other HSA inks I have tested.”
