These are water soluble archival printing inks. My preference is to hand apply using brayers or rollers, found objects for texture, and brushes for other effects. A very freeing way to use the medium. The normal way is to draw image onto lino or wood and cut or chip away the excess. The ink is then rolled over the image, the ground or paper is placed in a large printing press and the cut image in placed over the paper. Much like a humungous credit card imprint, the inked image is then pressed onto the paper. My method of direct application gives me freedom to texturise, and saves my fingers from the too-early gnarling from which some seasoned cutters suffer.
