StB Bar Coded Boarding Pass Implementation Guide In 2006 roughly 80% of the ATB printers can print 2D bar codes or can be upgraded to print 2D bar codes (see fig. 40). 2D bar code capability ATB printers (examples) Print 2D bar codes IER 567 Intermec PF4i Can be upgraded Fujitsu 9840 IER 557 Not 2D bar code capable Dassault BPR 600 IER 457 Installed base (estimation) 80% 20% Figure 42 - 2D bar code capable ATB printers installed base 5.6.4. Paper specifications Paper specifications for kiosks are described in Recommended Practice 1706e including: • Paper Grammage 1 • Thickness • Brightness • Thermal image optical density • Thermal image stability • Plasticizer resistance • Bar Code scanning • Print head residue Note: to identify direct thermal paper, just scratch the surface. If it scratches, it shows the direct thermal layer. If not, it means that the printer is using a ribbon with thermal transfer. 5.6.5. Bar code print quality The coding of the PDF417 requires several parameters. It is recommended to test the quality of printing with several test flights, on several readers and papers, before using the bar code in production. Here is some guidance on the main parameters: • Narrow bar (element) size: from 0.25 mm (0.010 in; 10 mil). • Height: minimum of 6.35 mm (0.254 in). • Ratio: Wide element to narrow element — not less than 3:1. • Quiet zone — as measured on the face material: o Minimum: 7 times narrow bar (element): 1.778 mm (0.070 in). o Preferred 10 times narrow bar (element): 2.54 mm (0.100 in). • Print Contrast Signal: not less than 80% at a wavelength of 633 nm. During the test phase, it is recommended to analyze the bar code print quality. ISO/IEC 15415 standard defines the “bar code print quality test specification – Two-dimensional symbols”. The test provides quality grades on various parameters, using scales with grades from 0 to 4 (see fig. 41). Codeword Yield Grade ≥ 71% 4 ≥ 64% 3 1 Paper grammage is a metric measure of paper weight based on the same square meter sheet of paper, regardless of paper grade. 58/128 27-May-2009
BCBP technical implementation ≥ 57% 2 ≥ 50% 1 < 50% 0 Figure 43 - Example of grading scale for measuring print quality of a PDF417 bar code The kind of parameters to be analysed are: codeword yield, symbol contrast, modulation, axial non-uniformity, grid non-uniformity, unused error correction. The result of a bar code check according to the test procedure would tell the grades for each of the parameters (see fig. 42).
