Silk Screen Printing - Print Washed Out

01/05/2009 7:10 PM

I have a silk screen shop and make some prints on shirts. One of the shirts was washed and the paint got off pretty easily. It was previously dryed with a hot air gun but unsure if I over/under did it. It was a double print (white) in a navy blue shirt, I dryed up the first layer pretty rapidly and gave the 2nd layer a good dry.

Does anyone know :

1.- average time to allow drying off with hot air gun on cotton shirts or polyester to avoid washing the print off.

2.- Problems if you over heat the print and how do you know?

3.- Problems if you under heat the print

Thank you, this was really helpful. Turns out one of the paint layers was overheated and did not mix well with the second one. Ahh.... it's the little details that ruin your process..

Glad the info helped.

Sites like that always helped me in my searches for information when I was dealing with screen, off-set and bulb (tampon) printing issues.

Quite often the manufacturers of the inks that you use will also have some tips and answers for the use of their products.

Take care and good luck.
