INK USE INFORMATION THE PAD PRINTING PROCESS The basic principle of the pad printing process is that the ink becomes tacky due to evaporation, first in the cliché before ink pick-up and then on the pad. This effect is used to transfer the ink from the cliché to the pad and then from the pad to the workpiece. 1. Pre-treatment of polyolefines To obtain an optimum ink adhesion on polyolefine, polyethylen (PE) and polypropylen (PP), materials must be pre-treated. The surface tension must be at least 38 Dyn = 0.038 N / m. The surface tension can be tested using the test pen (see accessories list...

Highly opaque silk gloss pad printing ink for the printing of various kinds of plastic materials like hard and soft PVC, coated polyester and PET-G, polystyrene and its modifications such as ABS, ASA,SAN, acrylic glass PMMA and polycarbonate PC, pretreated polyolefine PP and PE, manifold coated surfaces and layers as well as cellulose acetate CA and CAB, papers and cardboard products. very highly opaque, excellent fluidity, may be applied for open and closed machine system, quick drying. Most universal pad printing ink, opaque suitable for thermoplastic materials as well as duroplastics,...

USING THE VISCOSPATULA Instructions: 1. Stir the ink to ensure thorough mixing of the pigments. 2. Place the Teca-Print mixing cup in the Teca-Print cup holder. 3. Pour the required amount of ink into a mixing cup. 4. Add thinner drop by drop whilst constantly stirring. 5. Dip the VISCOSPATULA into the cup so that half of the large / top hole in the VISCOSPATULA is immersed in ink. 6. Lift the VISCOSPATULA vertically out of the ink. 7. As the ink flows down the VISCOSPATULA, watch how the holes open up from top to bottom. The amount of time it takes for the ink to flow from the first small...

oven cured Hardener must be used in an appropriate ratio to the ink. Strong deviations from the noted ratios above can lead to problems. Some problems may take a while to show and can eventually affect resistance and adhesion. Thus, after adding hardener and then thinner – this order is very important – the mixture should rest for approx. 15 minutes so that optimum ink flow and adhesion are achieved. Hardener only to increase the chemical resistance. Pot life can be reduced by approx. half for metal colour tones. With some ink types, pot life depends on a direct relationship to...
