Hint
Always test stones, materials, and
the heat press together before
starting full production of a motif
embellished garment or accessory.
All guidelines in this manual will
not work as described in every
situation.

Heat Press Guidelines

Ioline has collected and tested heat press processes that improve
results when transferring flat-back-hotfix Rhinestones and crystals
from motifs to garments and accessories. General guidelines and
advice are included below. There is no 'right' answer for all materi-
als, brands of stones, or heat press models. Always use the following
information as a starting point and test both the stones and materials
with the heat press before starting full production of a design.

Heat Press Settings

1. Optimal Temperatures are between 120° C (250° F) - 170° C
(340° F) depending on material and press time. The goal is to
get the glue hot enough to absorb into, and bond with, the ma-
terial but not to get absorbed completely away from the crystal.
a. If the adhesive soaks into the fabric, shorten the application
time first then reduce the pressure or temperature.
b. Larger stones require longer times OR increased tempera-
ture and pressure.
c. Mixing stones with large size differences, 30ss and 6ss for
example, may cause problems. The glue melts much faster
on the small stones and may get completely absorbed into
the material by the time the glue on the large stone is melted.
d. When applying stones to thicker fabric (pile knit, artificial
fur, denim, etc.), increase the pressure and application time.
e. When applying stones to delicate fabrics, decrease the pres-
sure and application time. Also test whether a Teflon® sheet
is required between the stones and heating element.
2. Arm Pressure set to LOW. Excessive pressure may damage the
stones or cause an undesirable finished product.
3. Press Time (heat press closed on design) depends on the tem-
perature and the material. The table below provides generic
combinations to start testing with.
