size of the barcode is known as magnification. Magnification
can vary within certain limits, and if the barcode is not between
these limits, it may not scan. It is the print quality of the
barcode symbol that determines the minimum magnification you
must apply, not a predetermined space on the packaging.
It is recommended that you use a magnification higher than the
minimum, in order to increase your barcodes reliability.
take into consideration that the designer must allow sufficient
space for the barcode, including a blank area called the light
margin or quiet zone before the first bar and
after the last bar, that enables the scanner to recognize the
beginning and end of the barcode symbol. The light margin is
included in our minimum size guides. But it is your printer who
must advise you of the minimum barcode size that will be able
to be printed on the product item. This is determined by measuring
the ink spread (print gain) and the extent of variation on the
ink spread during printing.
size of the barcode may only vary within certain limits. Generally
speaking, the barcode must be between 80 per cent and 200 per
cent of the standard or 'nominal' barcode size, as shown. EAN.UCC
barcodes should not be printed outside these limits as it can
reduce their ability to be scanned.
size guides will guide you to the minimum area required and tolerances
for standard magnifications.
