Heat Press Application Troubleshooting
1. Optimum heat transfer printing cannot be achieved unless the
temperature, pressure and time settings are accurately adjusted.
If the resulting color in your product is not acceptable, check
- Temperature: 380-410 degrees F.
- Pressure: 0 - MINIMUM PSIG
- Dwell time speed 3-5 feet per minute
If you continue to experience problems with color, consult with
the supplier of your plotter for proper calibration instructions.
2. "Ghosting" is a term used for double imaging. If you
experience this phenomenon, check the following:
- Make sure that your fabric is heat set prior to printing
- Excessive temperature can cause "blow out" of inks
in the gaseous state resulting in ghosting.
- Upon exiting the heated drum, the fabric and transfer paper
must be separated simultaneously.
3. If you experience wrinkling or uneven pressure in your fabric
or transfer paper during the heat transfer process check the following:
- Make sure the fabric and transfer paper have an even cut on
the leading edge prior to threading the machine.
- Thread the machine initially with fabric only. This will allow
you to preset the tension and insure proper alignment prior to
the heat transfer process. Next, place the leading edge of the
transfer paper face down on top of the fabric. Make sure the paper's
leading edge is even with the edge of the fabric. Apply pressure
downward so that the transfer paper will follow the same path
as the fabric into the machine.
- Make sure that your rolls of fabric have been supplied with
an even edge. Rolls of fabric that have "funneled" edges
will not track properly - resulting in wrinkling and uneven pressure.
- For optimum results, all pneumatic tensions controls on unwind
and rewind units should be set at 3-5 psig MAXIMUM.
- Check the belt for tears or rips. We offer a belt
welding repair kit for fixing teflon belts. Check our tips
for prolonging belt life.
