the washability of the nal print on light shirts that do not have white ink in the image by using
FastCOLOR pretreatment. For information on pretreatments and applying pretreatment, refer to Chapter
11 - Advanced Printing With White. Poor washability ON DARK SHIRTS may be caused by too much
pretreatment or from drying the pretreatment with a slick Teon sheet or silicone treated baking pan liner.
The slick surface may not allow the ink to adhere properly.
Humidity Concerns
For areas of greater humidity or where shirts are very damp after printing, try pre-pressing the garment for
a few seconds using a heat press. Doing this will also atten the bers giving a smoother print.
Variables such as climate and the amount of ink used can extend cure times. Certain garment fabrics may
also require more time. Even seasonal changes may effect already established times and temperatures.
Temperature Tests Vs. Wash Tests
Before doing a major production run, ALWAYS DO WASH TESTS and verify your dryer temperature.
For Heat Presses, the most accurate method of checking the temperature is with Paper Thermometer heat
tapes available from all screen print supply companies. Infrared ray guns do NOT always give accurate
readings on heat presses. For conveyor dryers, use Paper Thermometers or temperature “donut” probes
available from screen print supply companies.
Slight Discoloration
Some shirts might show a slight discoloration if using a Heat Press to cure the print. (This is most often
seen in Red and medium to dark garment colors other than Black.) This discoloration will usually go
away when the shirt cools or when washed.
Red dye is the hardest to control for discoloration because heat can permanently change the red pigment.
