Screentone is a technique for applying textures and shades to drawings, used as an alternative to hatching. In the conventional process, patterns are transferred to paper from preprinted sheets.<ref>Template:Cite book</ref> It is also known by the common brand names Zip-A-Tone (1937, now defunct<ref>Template:US trademark Zip-A-Tone: Registration Certificate – Manufacturer-supplied first use date</ref>), Chart-Pak (1949<ref>Template:US trademark Chart-Pak: Registration Certificate – Manufacturer-supplied first use date</ref>), and Letratone (1966, from Letraset<ref>Template:US trademark Letratone: Registration Certificate – Manufacturer-supplied first use date</ref>).
A dry transfer screentone sheet, sometimes informally known as a "tone", consists of a flexible transparent backing, the printed texture, and a wax adhesive layer. The sheet is applied to the paper, adhesive down, and rubbed with a stylus (also called a burnishing tool) on the backing side. The backing is then peeled off, leaving the ink adhered to the paper where pressure was applied.
