Title:
LASER MARKER
Document Type and Number:
WIPO Patent Application WO/2015/152231
Kind Code:
A1
Abstract:
Provided is a laser marker which enables efficient determination of an optimum condition for a printing pattern of a two-dimensional code and simplification of the evaluation operation of the printing pattern of the two-dimensional code.
A printing pattern regarding a cell to be printed in each of reference cells of a two-dimensional code is generated (S11, S18). The two-dimensional code is printed in this cell printing pattern (S12). The recognition rate of the two-dimensional code is calculated on the basis of the reference cells (S13, S14). When the recognition rate is a predetermined value or more, a present printing pattern is stored as an optimum condition (optimum printing pattern) in a database (S19). In contrast, when the recognition rate is less than the predetermined value, the size of cells constituting the present printing pattern is changed (S16-S18). The two-dimensional code is printed in the changed cell printing pattern (S12), and the recognition rate of the two-dimensional code is calculated again (S13, S14).
