Bar Width - When you create barcodes, you have the option of
choosing a range of widths for your barcode.
Foreground/Background Colors - When you create a barcode,
you can choose a foreground color (the color of the barcode
itself) and a background color (the color of the surface behind
the barcode). Choose foreground and background colors that
print with sufficient contrast to be scannable. Black barcodes
on white backgrounds are commonly used because they scan
easily. It may be useful to test a few of your barcodes by
printing them out and scanning them.
UNDERSTANDING BARCODES
What is a Barcode?
Barcodes are symbols that store information. They simplify the
movement and sale of goods and the storage, movement, tracking
and use of information. Barcodes consist of a series of scannable
bars and spaces that can be printed on packages, cartons, bottles,
and other commercial products. The bars and spaces in each
symbol are grouped in such a way to represent a specific ASCII
character or function. In addition to the scannable part of a
barcode, many barcodes have readable numbers and letters that
appear below and surrounding the bars. With products in the
grocery store, for example, the barcode stores a number that is
associated with a product. Through the stored number, the barcode
can be set up to cross reference an electronic file with information
such as the price and on-hand inventory counts.
