Inserting Barcodes and 2D Codes into a Job
When creating a Job that contains either 1D barcodes or 2D Datamatrix
codes, the following guidelines should be followed to ensure optimal code
quality and readability.
All 1D and 2D codes should be printed using a vertical resolution of
240dpi (100% density).
Note: For more information, refer “How to Adjust Print Resolution” on
page 5-17.
1D Barcode Optimization
1D barcodes (i.e. UPC-A) consist of a pattern of bars (ink) and spaces
(substrate) that must be printed a specific widths to be properly decoded
by a scanner. The width of the narrowest bar/space is referred to as the "x"
dimension (1x) and the increasing larger bars/spaces are some multiple of
the "x" dimension (2x, 3x, etc). The "x" dimension of a barcode is controlled
by setting the "Magnification (%)" value in the Properties window for the
barcode in CLARiSOFT.
Due to the range of potential Magnification settings and the inherent
ability to print in different horizontal resolutions, it is possible for a given
combination of these values to result in a lower verification grade, or
possibly not scan at all. While the printer will always preserve the vertical
height of the code, it can happen that depending on the horizontal
resolution configured in the printer, the optimal "x" dimension would
require a fractional drop of ink. As this is not possible, the printer will
round up or down to the next amount of complete drops, causing the
barcode to be longer/shorter than the programmed Magnification.
To keep this issue from occurring, it is recommended to always print 1D
barcodes at a Horizontal Print Density of 100% (240dpi).
Note: For more information, refer “How to Adjust Print Resolution” on
page 5-17.
2D Datamatrix Code Optimization
Datamatrix codes should be dimensionally as square as possible. Codes
where either the x (length) or y (height) dimension are unequal can result
in less-than-optimal bar code grading scores due to axial non-uniformity.
Due to the range of potential module sizes and the inherent ability to print
in different horizontal resolutions, it is possible for a given combination of
module size and resolution to result in a lower verification grade due to
axial non-uniformity. While the printer attempts to preserve the vertical
height of the code, it can happen that depending on the horizontal
resolution configured in the printer, the optimal module size would
