Technical information
Columns on porous plastic technology: what open-cell porous plastic is, marker nib types and flash stamps.
What is porous plastic? Porous materials have a three-dimensional network of pores, or cells, inside them. When the walls between adjacent cells are partially open, the material is called open cell. Air and liquids pass through it, while particles are trapped. Sponges, pumice stones, wood and paper are all open cell materials in everyday life. Open cell porous plastics use that structure for...

Alcohol markers, also known as art markers or graphic markers, mainly used for illustration, sketching and design purposes which are popular among artists, illustrators and designers, and are classified as marker pens. These markers have reservoirs inside of their bodies filled with alcohol ink, which are drawn into the marker nibs by capillary action. 1. Kinds of nibs for Alcohol markers Nibs of...

What is “Flash Stamp”? A flash stamp, also known as a pre-inked stamp, is a type of stamp that incorporates an ink pad within its construction. Unlike traditional stamps that require a separate ink pad, flash stamps have the ink reservoir built directly into the stamp itself or a foam die of the stamp already absorbed ink in itself.
