6.2.2 What is barcode?
A barcode is an optical machine-readable representation of data relating to
the object to which it is attached.
Originally, barcodes systematically represented data by varying the widths
and spaces of parallel lines, and may be referred to as linear or
one-dimensional (1D.
Later they evolved into rectangles, dots, hexagons and other geometric
patterns in two dimensions (2D).
In M a g n u m Slit-cut creaser, we use only
1D
barcode in near future,
which is based on
code39
.
6.2.2.1
Code
39
Code 39 is one of the protocols that define symbols as barcodes. The
definitions are as following:
Each code consist of 9 bars,5 in black, 4 in blank.
In 9 bars, only 3 are wide, others are narrow.
Left drawing is an example of barcode. 9 bars,
rightwards, are coded from 1-9,
As we can see 5 black bars (Nr. 1 3 5 7 9) , 4
blank bar(Nr. 2 4 6 8)
3 bars (Nr. 2, 5, 7 are wide and other 6 are narrow.
If this bar is read, system will take it as star symbol “
*
”
In Magnum barcode, Wide bar is 1mm wide, narrow is 0.5mm
wide.
