Frequently Asked Questions

Frequently Asked Questions

What pad printing ink should I use for plastics like ABS, polycarbonate, or polypropylene?

Selecting ink for plastics depends on the material’s surface energy and application requirements. Materials like ABS and polycarbonate typically accept standard industrial inks such as those from Marabu, while low surface energy plastics like polypropylene often require surface treatment (flame or corona) before printing. Ink selection should also consider durability requirements such as abrasion resistance and chemical exposure. In many cases, a two-component ink system with the proper hardener provides the most reliable adhesion.

Rubber and silicone are among the most difficult substrates to print due to their flexibility and low surface energy. Standard inks will not properly bond. For these applications, a dedicated silicone ink system is required, such as Automark’s specialty silicone printing ink. These inks are designed to flex with the part, resist abrasion, and maintain adhesion under repeated use. Cure method (room temperature vs. heat cure) should be selected based on production speed and performance requirements.

A hardener is used when increased durability, chemical resistance, or adhesion is required. Two-component ink systems (such as many industrial inks from Marabu) rely on a chemical reaction between the ink and hardener to fully cure. This is especially important when printing on metals, coated parts, glass, or components exposed to solvents, cleaning agents, or outdoor environments. Without a hardener, the ink may appear dry but will not achieve full performance.  Marabu H1 hardener also has a UV inhibitor built-in to prevent yellowing of white ink for outdoor applications.

Improving adhesion typically involves a combination of proper ink selection, surface preparation, and process control. For low surface energy materials like polyethylene or polypropylene, surface treatment (corona or flame) is often required. Adjusting ink viscosity, selecting the correct hardener ratio, and ensuring proper drying conditions are also critical. In some cases, switching to a different ink system entirely is necessary to achieve consistent results.

Medical device printing often requires inks that meet strict regulatory and performance standards, including biocompatibility. Many manufacturers use specialized industrial inks such as Class VI-compliant systems from Marabu, depending on the application. These inks are commonly used for catheter tubes, syringes, and other medical components where durability, traceability, and safety are critical. Ink selection should always be validated based on the specific regulatory requirements of the product.  Marabu offers three Class VI medical inks including TPU, TPR, and Maraprop PP.

One-component inks air dry and are typically used for less demanding applications where high durability is not required. Two-component inks require a hardener and undergo a chemical curing process, resulting in significantly better adhesion, chemical resistance, and mechanical durability. Most industrial and medical applications rely on two-component systems for long-term performance.

Pantone matching in pad printing is achieved using base color systems and precise mixing ratios. Both Marabu inks and Automark silicone inks can be formulated to match Pantone, RAL, or custom brand colors. Factors such as substrate color, ink opacity, and print thickness can affect the final appearance, so test prints are typically recommended to ensure accuracy before full production.  Marabu has the entire color guide online and available for free with registration at Marabu Color’s Manager site online here.  For the Automark silicone ink series, we can match any Pantone color and even offer our silicone inks in metallic colors.

Poor ink transfer can result from incorrect viscosity, improper pad selection, or environmental conditions such as humidity and temperature. Ink that is too thick may not release properly, while ink that is too thin may not pick up cleanly from the plate. Adjusting thinner levels, selecting the correct pad hardness, and ensuring proper plate depth are all key factors in achieving consistent transfer.

Pad printing inks can cure through air drying, heat curing, or chemical reaction (in the case of two-component systems). Air drying is suitable for basic applications, while heat curing accelerates production and improves durability. Two-component inks cure chemically over time and often reach full performance after 24–72 hours, depending on the system.  Automark AM-Si silicone inks are offered in two variants, a room temperature cure and an oven cured variant.

The correct ink depends on several factors including substrate, durability requirements, environmental exposure, and production process. Because of these variables, many manufacturers rely on testing and expert guidance to determine the best solution. Automark works directly with customers to recommend ink systems, optimize print parameters, and validate performance before full production.
