Ink Selection

Selection of the correct printing ink for a particular application depends on the demands of that application.

Examples of this would be adhesion to substrate, abrasion requirements, or whether the image should appear glossy or matte.

Single Component Pad Printing Inks

In many applications single component inks can be used. These inks have a longer pot life and are easier to process than two component inks. They may also be cured either by air drying or a heat source.

Two Component Pad Printing Inks

Two component inks are used for applications that need to have high mechanical resistance. For example, these inks are used on radio dials, computer parts and typewriter key pads. These inks chemically bond with the material on which they are printed after the thinner in the ink evaporates.

UV Pad Printing Inks

In addition to the standard solvent based inks, we have UV-curable inks. These inks are cured by ultra-violet light, this process changes the inks' molecular structure by forming macro-molecules. UV inks have several advantages over the standard inks such as reduced curing time, reduced solvent emissions, and a constant ink viscosity. However, because these ink use UV light to decrease curing time, special precautions must be followed when used. For example, the light source must be enclosed with direct contact avoided. Also, because such precautions are necessary, and because of environmental concerns (ozone is created during the drying process, therefore the dryer must be in a ventilated area), the process can be expensive.

Color Mixing System for Pad Printing

In addition to our standard pad printing inks, we are also able to provide mixing inks that, when combined, can reproduce all Pantone or RAL colors. This inexpensive and easily used kit comes with the twelve basic color tones and is available in one or two component inks.

Proper Pad Printing Ink Conditioning

Teca-Print pad printing inks are ready to use. However, the ink must be conditioned to reach proper viscosity levels, this will depend on your application and process requirements.
