inkpad

An inkpad is a porous pad saturated with ink used to apply color to rubber or clear stamps. It is typically constructed from felt, foam, or cotton fibers and set in a shallow tray or pad holder. When a stamp is pressed onto the pad and then onto a surface, the raised image is transferred in ink to the target material. The design of an inkpad aims to provide even ink coverage and minimize blotting.

Inkpad formulations vary by intended use. Water-based inks are common for bright colors and quick drying, while pigment inks offer stronger opacity and longer fading resistance; however, they may take longer to dry. Re-inking pads with compatible ink is routine to maintain consistent impressions, and pads may be refillable or replaceable. Some pads are labeled for archival or acid-free applications, and professionals may choose inks with specific lightfastness or pH characteristics. Proper storage and cleaning of stamps and pads extend their life.

In addition to traditional stamping, the term inkpad is occasionally used as a brand or product name for digital writing devices or note-taking products. In those cases, Inkpad refers to a device or software line rather than a universal standard, with specifications and features varying by producer.
