  • Up to 50% improvement in mounting accuracy in some instances


What are the differences between hot stamp and heat transfer dies?

Though the hot stamp and heat transfer decoration processes are very similar, a difference can be seen in the dies used. The molds used for hot stamp dies carry the image to be used. They are more complex than the molds used for heat transfer decoration where no graphic image is carried on the die (the image comes from heat transfer label itself).

Why should you look for a silicone stamping die supplier with deep expertise in artwork?

Ensuring high-quality hot stamp decoration depends upon having BOTH  artwork carefully designed for the application as well as Dies manufactured utilizing specifications tailored to the graphic’s requirements!  Click here to learn more about the role of graphic design and die manufacturing working together for superior decoration.
