DMRE Datamatrix Rectangular Extension
What is DMRE?
Data Matrix Code with additional rectangular formats.
The example code below shows an extended rectangular Data Matrix with a module size of 8x64 fitting well in the available space on the object:
Message about DMRE from Dennis Priddy, one of the original Datamatrix developpers
"I love it! Your implementation of the Extension could not be more perfect in its simplicity, execution and effectiveness. And yes, it does make me a bit proud to know that Data Matrix can still help solve real-world problems – when in the hands of some very smart people.
Thank you!
Best regards and best wishes,
Dennis Priddy"
Message from Henri Barthel, ISO/IEC JTC 1/SC31 Chairman
"We have just published a new DataMatrix rectangular barcode (ISO/IEC 21471), which can be engraved onto very small medical instruments and equipment for hospital theatres and used to track them. We are also working on a similar approach for a rectangular QR code (ISO/IEC 23941)."

Current Data Matrix Rectangular Formats (not DMRE)
Data Matrix following ISO16022 ECC200 already features the following rectangular formats:
| Size | Numeric | Alphanum | Byte | Example |
|---|---|---|---|---|
| 8 x 18 | 10 | 6 | 3 |  |
| 8 x 32 | 20 | 13 | 8 |  |
| 12 x 26 | 32 | 22 | 14 |  |
| 12 x 36 | 44 | 34 | 22 |  |
| 16 x 36 | 64 | 46 | 30 |  |
| 16 x 48 | 98 | 72 | 47 |  |
Use-Cases for extended Data Matrix Rectangular formats
The following use-cases require additional rectangular sizes if higher data amount must be encoded:
Highly rectangular marking surface
Typically, the height of 8 modules is used and should be extended to a higher width if more than 13 alphanumeric characters are encoded. The upper example encodes a standard product ID following EDIFICE guidelines for electronic products.
Curved surface
Curved surfaces like tubes should have a code at minimum height (typically 8 modules) and an increased width. The example features a PPN code on a drug.
Code height limited by printing technology
Continuous InkJet technology is limmited in print height while print width may be extended.
In consequence, a maximum module height of 26 modules should not be extended. Nevertheless, the requirements on data capicity for pharmaceutical products exceed the capacity of a 26x26 symbol and thus rectangular symbols help to solve this issue.
Especially the various serialization projects with inline printing processes mostly by inkjet technologies have shown a clear need for these new rectangular formats.
ISO/IEC 21471 DMRE
The ISO/IEC standard is published 2020-02-03 and may be purchased here:
https://www.iso.org/standard/70947.html
DMRE was developped within the working group ISO/IEC 1 / SC 31 / WG 1 as project 70947
https://sd.iso.org/projects/project/70947/overview#
I want to thank the very active members of this group who made this possible.
The prior versions of DMRE published by AIM and within DIN16587 had another set of chosen formats. The column "Standards" below includes the document covering the format.
The formats 24x32, 24x32 and 26x32 were present in DIN16587 and are not adopted by ISO/IEC21471 due to not sufficient width to height ratio.
New formats with height of 8 and 12 were added, as a use cases are seen for marking of round objects, specially in the scope of UDI.
New formats with height of 20 and 22 were added to support contact inkjet printing with an additional text line below the code.
