trouble heatsetting 4 color print

Hi, Am looking for help. Did a full back 3-color logo on a ash tee-shirt. No problems. Customer wanted same logo on black. Printed a white underbase, flashed with infared dryer, printed 2nd color flashed and third flashed...so far so good. Printed final black outline, all looked good until I did final heatset. I use heat strips to determine cure time , usually 40 seconds or so. I'm doing final cure with flash dryer. Black ink becomes "transparent". I can see white through it. The other colors look fine, except the black. It almost looks like the black is burning. Black is opaque over the other two colors, just not over the white underbase. What am I doing wrong? Over-flashing between colors? Thanks for any/all input. Great youtube video's.

Thanks for watching my videos. I’m glad I can help out through them. Thanks for watching and you’re very welcome.

Yes, it sounds like the black ink is getting too hot perhaps. I have never seen this particular situation before with only one ink being an issue like that. Try using less heat for flashing and making sure not to over cure on the finishing. I might also suggest trying a different black ink maybe or when printing the black shirts, "knock out" the black in the design so it's not ink. Instead the black in the shirt will be the black in the design. Follow?
