Synthetic fabrics are not recommended for use with iron-on films. This means material such as nylon, acrylic and leather should be avoided.  Any man-made or synthetic garments, generally, will risk melting under heat pressure!

Avoid using HTV on anything such as paper, plastic, lace, satin as they will not be able to withstand the heat.

We do not recommend to use heat transfer vinyl onto knitted garments and materials with an uneven or rough surface.

As a general rule, we do recommend that you consider running a test print and press before you oversee a large production run.
