BAR-CODE LABEL SPECIFICATIONS
4.6 BAR-CODE LABEL SPECIFICATIONS
General
The LH 700 Series System supports the use of of up to 16-character bar-code labels. A
bar-code consists of black lines (bars) and white lines (spaces), which are called elements.
There are narrow elements (NE) and wide elements (WE); their arrangement is determined
by the code.
Optical Characteristics at 880 nm ±10% and 633 nm ±10%
r
Print Contrast Signal (PCS): 80% min.
r
Reflectivity of Media (RW): 80% min.
r
Reflectivity of Ink (Rb): 16% max.
r
No spots or voids; no ink smearing.
r
Edge roughness is included in the bar and space tolerances.
Measurement method is according to American National Standards Institute's
MH10-8M-1983.
Printing Method
Photographic, or thermal transfer.
Label Thickness
Maximum label thickness must be such that:
r
The tube's outer diameter including the label is not greater than 13.3 mm.
r
The label including adhesive = 0.006 ±0.003 in.
NE/WE Ratio
Must remain constant over code length.
IMPORTANT
1. DO NOT use the following characters # @ [ \ ]
`
{ | } ~ in Specimen or Patient identifiers.
There is a potential for Specimen or Patient misidentification to occur. The system will substitute or omit
these characters when the system in configured in a language other than English or Chinese.
2. Risk of misidentification. Use of poor quality, dirty, improperly placed or damaged bar-code labels could
keep the instrument from reading the bar-code labels. Ensure the bar-code labels are undamaged. Ensure
the bar-code labels conform to the specifications provided in Chapter 4 of the Reference manual.
3. DO NOT use leading or trailing spaces in the ID.
IMPORTANT Possible misidentified results. For accurate reading by the scanner, it is important that
bar-code labels for specimen tubes adhere strictly to the specifications given in this section. Labels that
meet these specifications are available from Beckman Coulter.
