Heat Curing of Permaset Aqua
|
With any water-based ink, including Permaset Aqua, heat setting is absolutely imperative.
Almost any method of applying the appropriate amount of heat will cure the ink. Note that drying and curing are two separate processes. Some examples of how to cure the ink are as follows:
- 1. A professional drying tunnel
- 2. Hand iron after air drying. Although the print will not melt like a plastisol ink, best to iron the back of the image.
- 3. Again after air drying, fold piece, wrap in aluminum foil and place in a warm oven (about 190 degrees).
- 4. After thorough air drying, place a sample print in a clothes dryer for say 30 minutes and test wash.
All these methods are subject to suit local conditions, moisture content of fabrics etc. Best advice is to do a test piece
(or better, multiple pieces). These can be cured with the proper print, then taken out and evaluated at various stages of
the curing or heat-set process to test washability.
We do our standard lab tests straight after printing, with the ink still wet into an oven at 300-320F for 2-3 minutes. If the wash
test does not work, we put it in for another minute and we’ve yet to see a failure.
However, remember that more does not always mean better. Too much heat runs the risk of
a) singeing the garment and
b) overcuring, which will actually compromise the wash-fastness and will crack the print.
