Dry transfer graphics is a technique that was primarily used by graphic designers of early days to transfer graphics such as symbols, signs, letters, lines, colors, shades, textures, patterns, symbols, and signs from a transparent backing sheet onto a smooth surface, paper, or any other medium that the designer may use. It is also known as rub downs or rub ons. This is done by placing the decal backing side up in the desired location and then pressing or rubbing on the decal to transfer the pattern or design on to paper/or any other surface. Dry transfer graphics were mainly used in title blocks, forms, patterned lines, shading, piping, or electronic schematic symbols as a part of manual technical drawing. Computer graphics has almost replaced the use of dry transfer graphics.
