Digital decorators know that sublimation inks do not print white. In order for transferred images to appear vibrant, the substrate must be white or as close to white as possible to add opacity to the transfer so that the image stands out.
Unfortunately, many potential substrates that would make excellent decorated products are black or gray. For example, a piece of slate might make a lovely decorated award or photo gift, but without the proper coatings the transferred image would be very poor and commercially unacceptable.
In order to prepare a dark surface for sublimation imprinting, the item must first receive a White Base layer before application of Digi Coat Clear sublimation coating. The white layer will give opacity to the image. However, since heat is used in the transfer process, the white base coat needs to be able to withstand 200 degree heat without peeling or turning yellow. |
