Miniaturization of Dot Pattern by Metal Forming for Direct Marking of 2D Barcode Symbols
- 1.8k Downloads
To create information delivering ability on metal surfaces by microforming, a direct marking system of 2D bar code symbols (Data Matrix) on a metal plate as surface microcavities using a dot impact forming machine is developed via symbol images. Miniaturization of dot pattern was further enabled by introducing an x-y microstage to reduce the pitch of dots from 119 m to 30 m, resulting in 2D symbols at 840 DPI with successful rapid decoding by a PC-based optical system compatible with direct marking.
