Requirements for bar code printing

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.

Bar code scanners

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
