is a special technique in printmaking
in which the image is transferred to a surface that is bonded to a heavier support in the printing process. The purpose is to allow the printmaker to print on a much more delicate surface, such as rice paper
, which pulls finer details off the plate. During printing, a glue
is applied to the back of the paper (a paste made of rice flour
and water being traditional), and then the heavier support (typically, the heavyweight paper normally found in printmaking) is placed on top. In the pressure of the press, the lighter surface is glued to the support simultaneously with the image printing on it.
