Requirements for bar code printing
Bar code scanners

The quality and readability of printed bar codes will depend on several
factors that include:
• Texture and quality of the print surface on the selected surface of the
slide
• The color of the title block
• Bar code style (1D or 2D)
• Number and types of characters required in the bar code
• The quality and resolution capabilities of the bar code reader
As always, using Leica recommended print media will produce the highest
quality print. However, it is highly recommended that any bar code solution
be tested prior to implementation. Please check with your local representa-
tive for details on achieving the maximum number of characters with 2 D
bar codes.
The scanning results obtained not only depend on the correct bar code
creation and on the quality of the specimen slides, but also on the features
of the bar code scanner used.
Features to bear in mind are:
• Reading tolerance:
difference between actual bar width and nominal module size.
• Light color:
In order to obtain a high contrast with the specimen slides used.
• Optical resolution:
must be better than the module size.
Depending on the application, the following features should also be
considered:
• Maximum readable distance
• Maximum inclination angle
