ABSTRACT:
An improved sublimation transfer process for printing color images on elastomer-coated fabric such as woven nylon is disclosed. The improved process includes a preliminary step in which a transfer sheet having sublimable dyes placed thereon is subjected to a pretreatment to condition it so as to avoid ghost images or haziness that would otherwise result when applying such process to elastomeric coated material. The pretreatment is carried out by placing the dye-containing transfer sheet in contact with a sheet of absorbent paper and heating this assembly under specified conditions to cause excess dyes to be conveyed into the absorbent sheet. The resulting dye-containing absorbent sheet is then removed, and printing may be carried out using known process conditions. The improved process is particularly useful for printing multicolor images on the back side of Velcro hook and loop tapes.
