Abstract (en)
[origin: US6715867B1] A method for producing blocks on a support that are designed to be removed by scratching. An ink jet printing technique is used to produce the blocks. The ink used is of the type with phase change. The method can be used to form a support containing an information or a graphic design on its surface and a scratchable block masking the information or graphic design. The scratchable block consists of juxtaposed and/or superposed dots of material. The method is particularly applicable to smart cards.
