Screen Printing Ink

In printing, the most significant changes have come in the ink department. Ink is constantly changing to fit the needs of changing material. As the material of the substrate changes, so must the ink (typically through additives). For example, fabric manufacturers change dye, finishes, and processing procedures, which can have an adverse effect on the printing.

When trying a new product, be sure to follow the manufacturer’s recommended procedures and run your own tests. Watch for secondary problems along the way. For example, photopolymers don’t mix well with lacquer thinner, which sets the emulsion and makes its nearly impossible to reclaim. A change in one area may necessitate a change in another.
