I am pressing white vinyl on both red and royal blue shirts. I am using Siser easy weed, Gildan 2000 shirts. I pre-pressed it for four seconds at 302. I then pressed my design on the back for 12 seconds and you can see the imprint of the lower platen. That part of the shirt is now a dark red.

I have done lots of shirts, mostly black and white, some light gray. This is a first for me. It was really darker at first, it has lightened up some. It's completely cool.

Any ideas what to do? I waited until the last minute for these, thinking they would be quick. I have a backlog of shirts to do and this is the first batch I started on.

I don't think you have a problem or that the siser easy weed changed the color of the shirts. Red shirts show the darker color more than others but I have seen other colors adjust slightly as well. The color of the shirt should return as the garment sits. I think the color change has something to do with pulling the moisture out of the fabric while it presses but don't really know for sure.

It finally turned back to the shirt color after about an hour. I was in panic mode. :) I wonder also if I should press the design on right after I pre-press or if the shirt should cool. I am going to search the forums to see if there are any posts.

Thanks!

You pre-press the shirt to remove any moisture. If you wait too long before you press and depending on the humidity, you may let moisture back which will change the color. I was also in a panic with some royal shirts after pressing but they did return to normal after about an hour or so.

Thanks everyone, the shirts were perfectly fine after a few hours. I think I will continue to pre-press and then apply the design right away. My shop is in my basement, but we have the air on and I have a dehumidifier in that room.

I just did my Relay for Life team shirts last night and they turned out so cute. I am so glad my confidence in building and I am okay doing shirts and selling them. For awhile I was making shirts and giving them away so I could so how they did.

Vinyl remains my favorite to use on shirts, I might try two colors when I can practice again.

I'm happy to hear your shirts turned out beautifully. Preheating is done mainly to smooth out wrinkles & remove moisture. Just a quick down & up will do the trick.

Happy Printing!
