Dry transfers (also called rub-ons or rubdowns) are decals that can be applied without the use of water or other solvent. The decal itself is on a backing material such as paper or plastic sheeting much like a transparency. The dry transfer is placed in the desired location with the backing side up. The decal is then applied by burnishing the backing with a stylus or similar object such as a ballpoint pen. The contact side of the decal includes a pressure-sensitive adhesive; the combination of heat and pressure causes the decal to stick better to the new surface than to the backing. When the backing is removed, the decal remains. This allows for ink only where needed even if the pattern is delicate, because the backing supports the decal while it is being applied.
Dry transfers are used in manual technical drawing. Standard graphic elements such as title blocks, forms, patterned lines, shading, or piping or electronic schematic symbols are repetitively used. Use of a dry transfer reduces drawing time and standardizes appearance. Dry transfer lettering such as Letraset brand is used where hand-drawn lettering is laborious to apply.
Famous quotes containing the words dry and/or transfer:
“A medium Vodka dry Martini—with a slice of lemon peel. Shaken and not stirred, please. I would prefer Russian or Polish vodka.”
—Ian Fleming (1908–1964)
“No sociologist ... should think himself too good, even in his old age, to make tens of thousands of quite trivial computations in his head and perhaps for months at a time. One cannot with impunity try to transfer this task entirely to mechanical assistants if one wishes to figure something, even though the final result is often small indeed.”
—Max Weber (1864–1920)
