Printing with Fabric Inks
For the most part, screen printing on fabric is the same as printing on paper. Use only fabrics that can be subjected to temperatures of at least 275 – 375° F. Do not use on non-porous fabrics such as nylon. Pre-test all fabrics. Fabrics with sizing must be washed prior to printing. This will assure proper adhesion of the fabric ink to the fabric.
Five Important Notes for printing with fabric inks:
1. The screen frame is usually detached from the base and used alone. Usually two (2) people should work on the printing process – one holding the screen frame tightly against the fabric, and the other doing the printing.
2. On articles like T-shirts, a piece of foamboard, cardboard or paper must be put inside each garment to act as a barrier.
3. To improve the lubricity (slipperiness) of the ink, you may add the Transparent Base. To slow drying or to prevent screen clogging, add the Retarder Base (1-2 tbs. to 8 oz. of ink).
4. Wash-up of screens and tools must be done immediately after use. If they are allowed to dry on your screen or tools, they are difficult or impossible to remove.
5. After the fabric ink dries on the fabric, set a household iron at the highest dry heat (no steam) that will not scorch the fabric and with a cloth or paper between the iron and printed material, iron on each side for 3 – 5 minutes. This will make the ink withstand repeated washings.
IMPORTANT: PRE-TEST SAMPLES PRIOR TO ALL PRODUCTION RUNS. If inadequate wash fastness occurs, the print needs to be heat seat longer.
