Minimum code/basic commands
The minimum code is one mark in one line (insert).
However for reliability it is advised to use at least 2
marks.
The first line is the start mark.
A mark printed on the second line means insert. No
mark on the second line means accumulate.
Note
In some cases, on request of the customer, the reading of the basic commands can be
reversed by the service organization. This means that no mark is interpreted as an insert
command and that for the accumulate command a mark has to be printed.
Length
Above the first mark and below the last mark a
space of 8,5 mm (0.33”) must be kept without
printing. This means that the minimum code area
consists of 6 lines:
- 2 lines to print the (basic) commands
- 4 lines free space
Line distance may be 2,54 mm (0.1”) to 6,35 mm
(0.4”).
Code width, character spacing and pitch
The minimum width of the code area is 7 character spaces. From left to right:
- 2 characters space not printed (4,2 mm; 0.17”)
- track mark (3 characters or 6,3 mm; 0.24”)
- 2 character spaces not printed
Pitch 10 or 12 is accepted.
The track mark can be printed using the underline” sign (_), which must have a thickness
of at least 0,2 mm (0.08”).
