According to SignIndustry.com sublimation paper for use on textiles has a film coating that does not bind the dye. This allows the maximum release of dye on to the surface on which the image is being transferred.
Sublimation paper for rigid surfaces has the advantage of drying quickly, due to a silicate-based coating that allows vapor to escape. This type of paper may have a tendency to cockle or wrinkle.
High speed sublimation paper works well with high speed inkjet printers. This paper costs more than regular transfer papers, but dries faster, takes ink well, and does not cockle, according to SignIndustry.com.
