Miniaturisation in electronics is part of everyday life experience - but is it possible to print 3 pages of text on an area of 3 square centimetres?
This is logically conceivable in coded form, as binary information in a Data Matrix code. Yet it is only with the REINER jetStamp® printers that it becomes mobile!
For many years, REINER® mobile inkjet printers have been combining a Data Matrix generator and printer in a reliable, handy device. This offers a number of special features for Data Matrix code applications in industry and logistics:
• Direct printing of many DMC types on individual parts, products, packaging, cardboard boxes
• On almost all smooth surfaces made of paper, cardboard, metal, plastic, glass, curved surfaces, coated labels
• Print images can be transferred to the device via the supplied “PCset graphic” software or Windows based programmes such as Word, Excel or via a barcode label software or ERP system.
• Time saving due to fast print and transfer times
• Reliable marking and traceability in individual and series production

What is so special about the 2D Data Matrix code structure?
In the 1980s, a significant further development was achieved by encoding binary information not only one-dimensionally as a series of bars. The two-dimensional representation as square or rectangular "chessboard pattern" enormously expanded the storage capacity. This not only makes the Data Matrix code much more compact, but also more informative and robust. The data is coded as black and white boxes or as dots with gaps. This uniform symbol size makes reading the image for a scanner and subsequent decoding much safer.
In addition, the inventors of the DMC code have implemented a procedure for error correction which, with the help of the so-called "Reed-Solomon-Code", also enables the correct reading of a matrix code which is partially destroyed. The causes of such errors are quite common, e.g. scratches or soiling during the transport of packaging.
A further advantage is the lower demands on the black-and-white contrast between the screen areas: a barcode needs a contrast of 80% for a reliable readability by the scanner - with the Data Matrix code this is already possible with a brightness difference of 20%.
Today, 2D Data Matrix codes have established themselves as important identifiers for production control and administration, particularly in the industrial sector and warehousing, but also in postal dispatch and on tickets such as railroad tickets.
What does the Data Matrix code structure look like?
With the help of the boundary lines, the scanner software is able to "erect" the image again and correctly read out the actual data content - the matrix. The matrix size can range from 10x10 to 144x144 squares. The largest version of the matrix is capable of encoding up to 3116 numbers or 2335 ASCII characters.
The square DMC is visually similar to the QR Code (Quick Response Code), which is usually read with smartphones to call up websites, business cards or short text information.
Where is the Data Matrix code used?
In industrial production, the Data Matrix code enables semi- or fully automatic communication between the component and the processing machine, as well as complete documentation of the processing of all important individual parts into a product.
In logistics, the 2D Data Matrix code is particularly popular due to its robustness and storage capacity. When moving, loading and transporting packaging, abrasion and soiling are often unavoidable. The relatively high fault tolerance of the widely used Datamatrix ECC 200 nevertheless ensures secure information transmission.
Another advantage of the Data Matrix code structure is that it cannot be read by humans without scanners and software. It is therefore also suitable for storing discrete information in coded form, e.g. on letters, documents, stamp cards, personnel files, incoming goods checks.
What Data Matrix types are there?
Since the introduction of the two-dimensional data matrix code, the numerous development stages have been named primarily according to the method used for error correction. It started with the variant Error Correction Code 00 and led to the current standard ECC220. The International Organization for Standardization ISO defines the Datamatrix in ISO/IEC 16022:2006. The module size, i.e. the number of rows and columns of the 2D code, can be freely selected between 10x10 and 144x144, rectangular shapes are also permitted.
Various character sets are available for printing the binary information in coded form, ranging from pure numbers and ASCII codes to ISO/Windows codes and UTF-8.
GS1 Germany GmbH is the central commercial issuing authority for unambiguous Data Matrix codes in Germany and therefore names them GS1 Data Matrix. Globally unique codes are relevant, especially for GTIN article numbers. The GS1 Code is particularly common in the healthcare and automotive sectors.
Do I need a Data Matrix Code generator for a REINER® marking device?
Are Data Matrix Code labels suitable for professional everyday use or is it possible to print the DMC code directly onto a product?
The mobile REINER® marking devices are a smart alternative and generate the Data Matrix code at the click of a mouse using the supplied PC graphic set.
Now just place the device and apply the data matrix code to the goods at the push of a button - done!
The robust handheld inkjet printer models REINER jetStamp® 1025, jetStamp® graphic 970 or REINER® 940 do this job reliably and reasonably priced. Simply generate the desired Data Matrix code with just a few mouse clicks using the supplied software. If required, activate the function "continuous" (model jetStamp® 1025) and automatically generate serial numbers as DMC.
How can I print a Data Matrix code on metal, steel, glass and plastic?
For particularly smooth surfaces, REINER® has developed a quick drying ink that remains water and smudge-proof immediately after printing. The innovative technology of the handheld inkjet printer jetStamp® 1025 ensures an airtight closing of the ink nozzles when not in use. This prevents them from drying out and keeps these mobile marking devices functional at all times, even during long interruptions.
