What causes the ink to wash out or crack when laundered?

The most common reason for wash out and cracking in the ink is undercure. Wash out will usually occur with thin deposits of ink, whereas cracking is common on thick, undercured ink deposits.

In order to achieve a total cure, the ink film must reach the temperature recommended by the ink manufacturer. Most plastisol inks must reach a temperature of 320 degrees F (160 C). It is important that the ink film itself reaches that temperature.

Dryer readouts and temperature strip readings from the garment do not ensure that the ink is reaching the required temperature. It is vital that you map your dryer readings.
