Our MacBook Sleeves are printed using a sublimation printing technique. This is an indirect way of printing: the design will be printed on special paper first, using sublimation inks. After this, the print is sublimated from the paper on to the product. We align the paper on the MacBook Sleeves. We use high temperature and pressure to start the sublimation process. The special material on the outside of the MacBook Sleeve absorb the sublimation inks.
