How Do you Mix Ink for Print Pads?

Step 1. Select the correct ink series

Depending on your substrate, it is important to choose the correct ink. Pad printing ink is available in a variety of series, each created for a unique solution. Whether it is better adhesion to plastic or a high-quality ink for glass, there is an ink available.

Step 2. Add the Catalyst (Hardener)

This next step depends entirely on the ink series. Most inks require the addition of a catalyst, also known as hardener. Hardener is added to the ink to increase adhesion and improve abrasion resistance. The ratio of hardener to ink is dependant on the series as well, typically it's about 10:1.

Mix well before adding the solvent.

Step 3. Add the Solvent (Thinner)

Solvent is an additive to pad printing ink. Solvent is mixed with ink to assist in the transfer and drying of the ink from the pad to the part.

Solvent is available in a variety of types. Certain solvents only work with particular ink series. Other solvents work with multiple ink series and vary be evaporation rate (speed). The evaporation rate is an important factor because climate, print speed, and application all play a factor in how well the ink will transfer to the part.

Step 4. Mix Well
