Even the experts who have treated the metal surface for a long time might find the term rather unfamiliar. This process includes deep etching of the metal surface, insertion of special resin into the etched parts, polishing and compressing printing paper for dye sublimation in the resin parts so that the dyes could penetrate into the resin parts.

1) Size of Resin
Lapping is impossible in the mirror polishing if resin is inserted in space that is too broad. So the unit size should not exceed 25㎟ .

2) Printing Pattern
Minimum charge is added in case the client wants a special printing pattern since there is a certain limitation for printing.
