For traceability, authenticity, and critical identification, more industries are turning to ID matrix codes to replace barcodes.
For traceability, authenticity, and critical identification, more industries are turning to ID matrix codes to replace barcodes.
Primarily the electronic, automotive, aerospace and medical industries have the greatest needs.
Because of its small size and large information capacity, 2D matrix symbology is leading the way in these industries.
Such codes can be printed directly onto product or product packaging in a variety of ways, but probably the most flexible is laser.
Laser marked codes have the added advantages that they tend to be very permanent, highly resolved and add no inks or labels.
Rofin is a market leader in the design and manufacture of laser marking and coding solutions.
The matrix code, unlike regular codes or stacked barcodes, is made up of individual elements or cells of equal size.
These cells form a matrix similar to a checkerboard.
Most often this matrix is square, but elongated rectangular codes are sometimes used if the space available is restricted in one dimension.
The information is stored in the matrix by the selective placement of the black and white (or dark and light) cells.
Because this matrix can be made very dense, a large amount of information can be held in a very small area.
A two-dimensional reading device employing a CCD camera is necessary to read the symbology.
Such readers are available off the shelf from a wide variety of sources.
Rofin-Baasel supports a wide array of error correction code formats with square and rectangle data matrix codes, including the automotive code ECC200 (data matrix with up to 2335 alphanumeric characters in a field of 1in2 in a matrix of 144 x 144).
This allows customers to incorporate a greater amount of data into a smaller footprint than was possible with barcode technologies.
Where mark quality, marking speed and reliability are of key importance, the Rofin Multiscan VS laser marking system offers the ideal solution.
With dual axis scanning technology the Multiscan can mark both small and large characters at speeds in excess of 1000 containers per minute.
Exceptional mark appearance and legibility is maintained at all speeds.
As well as 2D matrix codes, complex graphics and traditional barcodes can also be marked within the Multiscan's large 105mm square scanning field.
At the heart of the system is Rofin's proprietary diffusion cooled carbon dioxide laser technology.
This high power laser coupled with its flexible beam delivery system allows marking of most commonly used packaging materials, including curved or irregular shaped containers.
Operator friendly software allows variable or fixed codes to be marked under local control or via a plant computer.
Lasers provide an indelible, permanent mark without the need for any routine consumables such as inks or solvents, they are easily integrated into the production environment and can operate continuously without frequent maintenance, cleaning or adjustment.
In addition to the Multiscan, Rofin manufactures a wide range of laser marking systems, both CO2 and YAG based, and continue to be the market leader in the area of laser marking.
