One stroke has a ELT-s white ink that is great for comfort colors straight print with no bleed blocker as it is a low cure ink, I've used it and also bleed blocker grey from wilflex when I use other white inks for top color..hey thanks Jason for the tip on adding white to the grey blocker I have some now from international coatings that seems a little to dark for top colors, I'll try that. I like the vintage look style print when I print comfort colors and If I can and the customer approves I like the bleed look.
