Before adjusting the bar code scanner to the bar code label location on
the microplate, some general guidelines to the preparation and quality
of the bar code label need to be followed for optimum performance:
• The minimum height or size of the symbol bars will depend on
the code symbol and the density used. Try to keep the height of
the symbol bars to more than 0.12 in.
(3.0 mm).
• Do not change the aspect ratio required by the label printer. Do
not force the bar code symbol size to fit on your label space i.e.,
maintain the aspect ratio free of distortion.
• Align the bars horizontally (side-to-side) and vertically (top-to-
bottom) if possible, to keep space available on the bar code
label.
• Keep a few millimeters (2–4) of empty dead or silent zone on
both ends of the code-symbol lines. Keep all symbol lines away
from the label corners and lifted edges. Optimize your
characters so there is no need to cram a lot of lines on the label.
• Keep the longitudinal dimension of the labels/symbols to less
that 1.25–1.50 in. (30–40 mm).
• Choose the media (label substrate material or paper) print or
transfer ink to give good contrast and optimal reflection.
Metalized, very shiny or clear background labels may be less
reliable. Test a sample if using a new color or surface material.
