Abstract
A multidimensional heat-seal emblem having a digitally-printed image on one side in registration to a three-dimensional relief profile. The emblem has enhanced aesthetic impact, flex, stretch, durability and is suitable for soft goods. A method of production is also disclosed that provides 0.05 mm level relief detail with high profile features up to 6 mm in height.

A sheet or roll-fed process to create a printed flexible and stretchable heat transfer emblem having an embossed relief pattern on one side, comprising the steps of:
- coating a stretchable thermo-plastic film with an ink receptive layer;
- printing on one side of the stretchable thermo-plastic film using a digital printer to define printed areas and unprinted areas, the thermo-plastic film comprising a hot melt adhesive;
- using a sheet or roll-fed process, applying a polymeric protective layer over the printed side of the thermo-plastic film;
- using a sheet or roll-fed process, adhering the unprinted side of said thermo-plastic film to a moldable foam substrate by an adhesive-backing on one side of said moldable foam substrate to thereby produce a multi-layer substrate, the adhesive backing comprising a thermoplastic adhesive, wherein the thermo-plastic film comprises layers having graduated melt temperatures such that a side of the thermo- plastic film facing the ink receptive layer melts at a higher temperature than a side of the thermo-plastic film facing the moldable foam substrate;
- heating the multi-layer substrate to a compression temperature that allows the polymeric foam to remain compressed after molding;
- embossing the multi-layer substrate by placing the printed thermo-plastic film against a mold having a lower temperature than the heated moldable substrate and a surface relief profile until the multi- layer substrate permanently retains the relief profile with profile changes of up to 6 mm and profile details of at least 0.05 mm, the molded multi-layer substrate being capable of elastic elongation in one direction within a range of 2% to 75%;
- removing the embossed multi-layer substrate from the mold;
- and
- trimming the embossed multi-layer substrate to provide said stretchable emblem having an embossed relief pattern on one side.
A sheet or roll-fed process to create printed flexible and stretchable heat transfer emblem having a three-dimensional surface relief profile, comprising:
- coating a thermo-plastic film with an ink receptive layer;
- printing onto one side of the thermo-plastic film to define printed areas and unprinted areas, the thermo-plastic film comprising a hot melt adhesive;
- using a sheet or roll-fed process, applying a polymeric protective layer over the printed side of the thermo-plastic film;
- using a sheet or roll-fed process, adhering the thermo-plastic film to an adhesive-backed moldable substrate to form a multi-layer substrate, the adhesive backing comprising a thermoplastic adhesive, wherein the thermo-plastic film comprises layers having graduated melt temperatures such that a side of the thermo-plastic film facing the ink receptive layer melts at a higher temperature than a side of the thermo-plastic film facing the moldable foam substrate;
- heating the multi-layer substrate to a compression temperature at which the moldable substrate can permanently compress;
- embossing the multi-layer substrate using a mold having a lower temperature than the heated moldable substrate and a relief profile until the moldable multi-layer substrate takes on the relief profile with profile changes of up to 6 mm and profile details of at least 0.05 mm, the molded multi-layer substrate being capable of elastic elongation in one direction within a range of 2% to 75%;
- removing the molded multi-layer substrate from the mold;
- cutting the molded multi-layer sub in selected areas;
- removing the cut/selected areas to produce a flexible and stretchable emblem having a three- dimensional relief profile on one side.
