The recognition rate for the barcode varies depending on the media type, barcode reader's performance and so on. The barcode rank may decline due to missing dots or curving on the ink drops, making the barcode unreadable by the barcode reader. Thus, we recommend that you try printing HRI characters and so on. 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 2 pixels and increasing the blank space by 2 pixels (Bar width adjustment). • Synthetic label Barcode type Printing direction Code39 Codabar(NW7) Code93 Code128 GS1-128 ITF GS1 DataBar Omnidirectional GS1 DataBar Truncated GS1 DataBar Limited GS1 DataBar Expanded UPC-A UPC-E JAN13(EAN) JAN8(EAN) Fence Ladder Fence Ladder Fence Ladder Fence Ladder Fence Ladder Fence Ladder Fence Ladder Minimum Module [by 600 dpi] ANSI Grade C or higher ANSI Grade B or higher 5 6 5 6 5 6 5 6 5 6 5 6 5 6 5 6 6 6 6 6 6 6 6 6 7 7 7 7 The recognition rate for the barcode varies depending on the media type, barcode reader's performance and so on.
