As we all know, sublimation transfer paper is a coated paper, made up with two important parts : the base paper and the sublimation coating, which all have contains moisture. When you put the sublimation paper in a environment of dry air and high temperature, the moisture will evaporate. At this time, if the moisture of the base paper and the coating evaporate inconsistently, the paper will curl. The process of the moisture evaporation, we call it ‘scalability’. Once crimped, paper can scratch and damage the printer’s sprinkler head.
