WATERSLIDE |
|
HEAT RELEASE |
Porous paper with a water soluble coating on one side. This coating consists mostly of dextrin or starch. |
Paper |
Rigid non-porous based paper with a wax or silicone coating on one side. Wax coating can be as thin as 4 g/sq.m and as thick as 12 g/sq.m. |
The decal must be soaked in clean warm water for 30-45 seconds to allow the decal to release from the paper. The decal can then be placed on the ware by sliding it off the paper or picking it up off the paper and placing it on the ware. The water and dextrin must then be squeegeed from the surface and underside of the decal. The decal then must be dried with a lint-free cloth and air dried. |
Transfer |
The decal is transferred from the paper to the ware by machine. For indirect transfer, heat is applied to the backside of the decal on a heated plate (150-200 °F). A low durometer silicone pad (heated 190-320 °F) picks the decal off the heated paper and places it on a pieces of ware at room temperature. For direct transfer, the decal which is reverse printed, is applied directly to the substrate. |
Overnight recommended |
