Lawrence Hereford Printmaking Pads are designed for wood engraving and letterpress but can also be used for intaglio and other printmaking techniques. They feature sheets of Hereford 145gsm acid-free natural white paper which has a very smooth surface for excellent results when hand-burnishing relief prints. Hereford paper is machine-made, part cotton rag, and is sized internally and externally with vegan gelatine.
