We guarantee that the print will stay on your shirts. If a screen printed image doesn't stay on the garment it is because the printer fails to properly monitor the final product as it rolled of out the dryer. A printed image must get to a temperature of 350 degrees all the through the image. If you have a thicker ink deposit on the tshirt the tshirt will require a longer time in the dryer. When a print cracks and peels on a tshirt it is because the screen print was not allowed to be fully cured. Each job has to be monitored separately to have the highest quality image possible.
