- (a) placing an insert/inserts into a mold in which a rubber object is to be cured, said insert having blades thereon having specific spacing and frequency unique for said rubber object;
(b) filling the mold with uncured rubber;
(c) curing said rubber and fixing the spacing and frequency of sipes corresponding to said blades in the cured surface of the rubber object; and
(d) using a zero contrast reading device to read the height and width of rubber bars between said sipes to provide information such as a serial number identification and/or part number identification for said rubber object.

Abstract
Siping, of a specific pattern, is used as a code to provide an identification number and/or a part number on a rubber object. The depth and width of the sipes, and the height and width of the rubber bars between the sipes, can be read using a zero contrast reading device, and the specific pattern of sipes and bars can be converted into identifying symbols such as letters and/or numbers. The identity of the object can be matched with a data base which may provide the history of the object.
