High Precision Pad Printing Services

Liberty Clark, Inc. provides high-quality precision pad printing services for the industrial and medical device and diagnostics markets. The core of our business is focused on medical device pad printing.

Medical device standards are extremely high. Precision, repeatability, and documentation is key. Certified ISO 9001:2015, Liberty Clark is committed to continual process improvement. Our 20 plus years of expertise and state of the art equipment is uniquely suited to meet specifications for all types of industrial and medical devices.

Furthermore, our pre-treatment and post-treatment process dramatically improves adhesion on substrates such as PP, Nylon, PC, Acetal, and Silicone. Our equipment also allows us to print on irregular shaped surfaces for products such as catheters, syringes, and hypo tubes.

Class 7 Cleanroom

Our certified Class 7 cleanroom is a special-use room reserved for pad printing jobs which require a very low particle count environment.

Before starting a pad printing job for medical devices, we filter all the air out of the Class 7 clean room to remove contaminants.

Throughout the pad printing process, air is continuously recirculated through High-Efficiency Particulate Air (HEPA) filters.

Benefits of Pad Printing

Pad printing is a gravure-printing process that makes it possible to transfer a 2-d image onto 3-d objects.

Unlike other printing processes, pad printing has the ability to print on nearly any shape or surface including concave, convex, curved, uneven and hollows. For medical devices, this means accuracy and precision on devices such as syringes.

Pad printing is also capable of printing on almost any material including plastic, metal, glass, ceramics and even food.

Lastly, pad printing offers better resolution than other printing processes. Resolution is key for printing on medical devices for obvious reasons.
