I've been using Fruit of the Loom Performance T shirts for sublimation for a while. Recently I've had a few where a blueish shadow is being left on white shirts which coincides with the heat press plate size.
I'm printing for 60 secs at 190 degrees as recommended.
Has anyone else come across this issue and if so what's the solution?
Problems with Fruit Performance Ts

The background is white but this is appearing on the part of the shirt not covered by the sublimation paper.R.Prints;132997 wrote:Make sure the background is white and not off white.

That will be dye from other shirts, pressed previously.
Have you been pressing any blue (ish) coloured garments? Either 100% poly or poly/cotton.
When polyester is dyed the dye works in a very similar way to sublimation ink. When it gets to about 160c and upwardes it turns to gas and will stain the platen.
Hivis and performance fabric/sportswear are the biggest offenders, but it also happens to a lesser extent with poly/cotton.
The way aroungd it is to use a sheet of pressing paper between the garment and the platen. Xpres sell some but they are to small to cover the entire platen. Best bet is to get some from Novachrome. Theres ( chip wrap) is big enough to cut in half and still cover a 15 x 20" platen.
