I've been using my Viper for about 6 weeks. After lots of trial and error, shirts are coming out okay, but there's still room for improvement. Biggest problem is fibers showing through when printing on dark colored shirts. I am doing all the "tricks" suggested here and elsewhere, but I'm wondering if there's a particular shirt that people have found prints best. I am using Gilden 2000, but I've heard ringspun cotton is better. What brand and style do you use.
I have found mixed results with Gildan as it is difficult to get the fibers to stop "peaking" thru the white ink. However the best results came from pressing for 10 secs, then pre-treating, then pressing for 15 secs with silicone sheet, then printing, "hover" cure for 15 secs then press as normal. Johnny Bobbin are very good shirts for digital textile printing.
Okay so I made my own template in Corel, but can anyone tell me why the ink looks like it's bleeding into each other? Using color layer, light cotton, White highlight setting at 30%, Viper gap narrow. t-shirt is 100% Hanes tagless. Any suggestions?

after you use the pretreat and spray it do you use a foam rollar on it before you heat press?
sounds like you are missing a step

Okay I got the bleeding to stop, now I can't get the black to come out black enough... It's a beige shirt not white. I'm printing straight from Corel and use white highlights. Yes I use a foam roller after pretreating but again I got it to stop the bleeding.
Again thanks FatKat that worked now a different problem. I think I saw something about this somewhere but the white ink layer is off to the side a little anyway of getting it lined up again?
Here is a picture it is hard to see on the biege background
Hello Damdesign,
you have to adjust the feeding parameter for the second ink layout very precisely. to do so you have to do some test prints with changing the feed adjusment like +/- 0,100 mm or even 0,050mm to obtain the best result. Each printer has a different parameter, so you have to find it by yourself
