Therefore, fence barcodes (when the barcodes from the start to stop are printed in a horizontal direction) are recommended to use. To use ladder barcodes, make consideration such as printing HRI characters. *2: Ink may penetrate the paper due to its characteristics, and bars of printed barcodes tend to become thicker. This tendency is more prominent with some papers. To maintain the barcode recognition rate, use methods such as reducing the data in a bar by 1 pixel and increasing the blank space by 1 pixel (Bar width adjustment). However, do not apply this method to 2-dimensional symbols. 92
