WHICH BAR CODES CAN THE IRISPEN READ?
Let’s discuss the IRISPen’s bar code reading capability in depth now that we
are familiar with its operation. Which bar code symbologies can the IRISPen
software read? What limitations does the IRISPen scanner have?
As far as color tones are concerned, the IRISPen works best on well con-
trasted bar codes. Black bars on a white background yield the best results. (We
repeat that you can use the image adjustment features to adapt the scanning to
your documents and that red and yellow are the IRISPen’s invisible or “drop out”
colors.)
Secondly, the printing quality is relevant: only laserprinters and inkjet print-
ers provide sufficient quality. Matrix printers should be excluded as they do not
produce sufficient sharpness - their resolution is mostly limited to 60 dpi - and
contrast - even when the brightness is adjusted. Here’s an illustration: this bar
code gives you the following black-and-white image when scanned.
Furthermore, you are recommended to scan on a flat, stable surface. Al-
though you will undoubtedly succeed in reading some bar codes on physical ob-
jects such as bottles, boxes etc., these are not part of the intended IRISPen bar
