Ribbed Base Sheets

Ribbed Base Sheets

RIBtype base-sheet is used on marking devices to hold type. It is affixed to hand stamps, coders, self-inkers, print wheels, and print heads. Base sheet can be ordered with adhesive back and/or 1/8" sponge to meet your requirements. Standard base sheet thickness is .155". Base sheet can be ordered in large sheets or cut-to-size to suit your application. When cutting-to-size, cuts are always made between ribs. Length tolerance is +/ 1/32" or 2%, whichever is larger. Smaller tolerances, when necessary, are available by quote.

Base sheet is readily available in natural rubber and buna, but can also be made in other materials.


Red/Gray Natural Rubber is best for general purpose use with alcohol and water-based inks. RIBtype natural rubber type has a red-orange face with gray ribs. It is available in standard 50 durometer or soft 30 durometer.

Black Buna is oil and acid resistant and is best for use with oil-based inks or when the type is exposed to petroleum products. It is available in hard 90-durometer, standard 50-duro or soft 30-duro. Hard buna works well in recipricating air/electric powered printers. Soft buna helps in printing large, bold characters on uneven surfaces.


Black Neoprene is very similar to buna. It is oil and acid resistant and makes excellent imprints. It is frequently used in place of 50-durometer buna.

Green PVC is flexible plastic material that provides greater durability in some applications. It is oil and acid resistant and is sometimes recommended for printing small text on plastic or film and for printing on abrasive surfaces such as Tyvek or brake shoes. Because PVC transfers less ink imprints may dry faster. Excellent for air/electric-powered recipricating printers.

Silicone This blue-and-white (blue face/white ribs) material is used primarily with thermal ink-transfer printers and for hot stamping. It has a high heat tolerance, making it a low cost alternative to metal type.
