Claims20
An article having a surface marked by a pulsed laser comprising a predetermined grid pattern:
- wherein the predetermined pattern comprises a logo, drawing, artwork, UPC code, QR code, and combinations thereof;
- wherein the grid pattern comprises a plurality of locations positioned in two or more rows, wherein the two or more rows are parallel, each adjacent pair of locations of the plurality of locations along any of the two or more rows is separated by an X-distance and each adjacent pair of the two or more rows is separated by a Y-distance;
- wherein consecutive marks are formed in the predetermined pattern by constant surface velocity (CV) bitmap marking and wherein a beam of the pulsed laser moves across the rows at a constant surface velocity greater than 8 m/s as the consecutive marks are formed;
- and,
- wherein the predetermined pattern has a Y-Distance standard deviation less than 0.040.
