Ross Loveday: Blue. - Carborundum, a technique where a mix of acrylic binders and carborundum grit are painted on to the surface of a plate and then inked as a intaglio plate. Its raised texture typically gives a deep tone, rich colour and strong emboss into the paper. - Drypoint is an intaglio technique where the image is drawn directly into the plate using a sharp drypoint tool. The resulting incised line has ridges of metal either side giving the characteristic rich blurred line.
