Pad Printing Inks
Solvent-based and UV-curable pad printing inks for decoration, marking and identification on three-dimensional parts.
Overview
Unique solutions for the toughest surfaces
Enhanced and fine-tuned over decades, pad printing has become a firm fixture in the printing landscape. The technique offers unique solutions for some of the toughest surfaces: closures, syringes, connectors, keypads, toys and cosmetics packs. Suitable for a wide range of applications and substrates, it ensures first-rate results for decoration, marking and identification.
Designed to work on all popular printing equipment, Uniform Industries pad inks achieve results even on difficult substrates. All inks are manufactured to the highest quality management standards.
The pad printing ink range
Five series covering everyday substrates through to medical-grade and untreated polyolefins.

Series detail
UNIPAD-10GP — general applications
An eco-friendly pad printing ink that adheres to ABS, lacquered surfaces, metal, natural fabrics, plasticised PVC, polyamide, polycarbonate, polymethacrylate, polystyrene, polyurethane and rigid PVC, plus the following treated materials: PETG, polyacetal, polyester, polyethylene and polypropylene, as well as wood.
UNIPAD-20HR — high resistance
High gloss, one- or two-component ink with the highest resistance against chemicals and gasoline, high opacity and abrasion resistance. Prints on translucent plastics, injection-moulded products, ice packs, medical devices, vinyl balls and cosmetic containers.
UNIPAD-11MD — medical grade
Medical-grade, highly opaque pad printing ink with high abrasion resistance. Prints on stainless-steel mugs, coated metals, pens, promotional items, automotive knobs and buttons, hard hats, containers and coins.
UNIPAD-12PP — untreated polypropylene
Speciality ink designed for untreated polypropylene, with high gloss and fast curing. Prints on stadium cups, frisbees, syringes, medical devices, measuring cups, cosmetics and industrial housings.
Owing to the production process, some polypropylene materials show lubricant residues on the surface which can reduce adhesion of the ink film. Preliminary trials are essential to determine suitability for the intended use.
UNIPAD-15LX — rubber-like substrates
Excellent adhesion to apparel and rubber-like substrates with high flexibility, gloss and opacity. Prints on stress balls, sporting goods, skateboard wheels, soft-touch surfaces, soft PVC, ID cards, binders, report covers and textiles.

Technical background: surface energy and adhesion
Pad printing puts a very thin ink film, typically 5–10 µm wet, onto plastics that range from easy to hostile. An ink can only adhere where it first wets, and wetting requires the surface energy of the substrate to exceed the surface tension of the ink by a margin — as a rule of thumb, substrate ≥ ink + 10 mN/m.
Pad-printing inks are formulated at about 28–32 mN/m. PVC, PC, ABS, PS, PMMA and PET sit at 39–46 mN/m and print directly. Polyolefins such as PP and PE sit near 29–31 mN/m untreated and need flame, corona or plasma treatment, or an ink formulated specifically for them. POM and silicone need treatment in every case.
