Application of Ceramic Doctor Rings for PAD Printing

SCERAM is one among the first suppliers of ceramic doctor rings for use in the pad printing process technology. The company manufactures ceramic and tungsten carbide standard doctor rings for all the major pad printing machine brands, including MICROPRINT, KENT, and TOSH. SCERAM also supplies products to the end-users of pad printing machines.

Pad Printing

Pad printing (Figure 1), also known as tampography, is a printing method capable of transferring a two-dimensional image onto a three-dimensional object. This is achieved by utilizing an indirect offset (gravure) printing process, wherein an image is transferred from the cliché onto a substrate through a silicone pad.

Pad printing is applied for printing on otherwise difficult-to-print-on products in a myriad of industries, including automotive, medical, electronic objects, apparel, promotional, as well as toys, sports equipment, and appliances. Functional materials such as conductive inks, lubricants, dyes, and adhesives can be deposited using this process.

Ceramic Doctor Rings

Ceramic doctor rings (Figure 2) bring significant benefits over regular steel blades. The estimated lifetime of ceramic ring is 10 folds longer than regular blades. SCERAM provides an extensive list of ceramic and tungsten carbide rings for use in the pad printing process. The company is capable of producing any kind of doctor ring as per the requirements of customers.

Ceramic Pad Printing Clichés

SCERAM manufactures ceramic clichés (Figure 3) for pad printing applications. Ceramic pad printing clichés is an advanced solution compared to regular steel clichés. Ceramic clichés are immune to any scratches eventually caused by abrasive components of paints used during the pad printing process. This quality of ceramic clichés significantly reduces the number of maintenance operations.

SCERAM now supplies Alumina ceramic clichés for use in the pad printing process. With remarkable resistance to abrasion, wear and corrosion, Alumina ceramic cliché exhibits much longer lifetime compared to regular steel clichés. The hardness of Alumina is 1800HV, a much higher value than the hardness of steel of 700HV. The development of new etching techniques enables engraving intricate images on Alumina ceramic clichés.


SCERAM constantly takes efforts to get familiar with latest technical improvements in the world of advanced ceramics. This application-oriented way of thinking helps the company deliver ideal solutions to meet the requirements of customers.
