Appendix C: Bar codes
The bar code was developed as an automated identification system
for simplifying warehouse and stock taking procedures. The quali-
ty of the bar code is superior to OCR-A and OCR-B, as the quality of
OCR-A and OCR-B may be affected by external influences.
The following factors may influence the readability of bar codes:
●
the print process and the sharpness of the stripes.
●
the status of the printer and of the print head.
●
the quality of the pins and the pin mechanism.
●
use of a multicoloured ribbon, its age and colour intensity.
●
functionality of the device used.
Furthermore, the following characteristics of the labels influence
the readability of bar codes:
●
reflection
●
smoothness of surface
●
transparency
●
surface´s consistency
●
colour
●
age of labels
