The A to Z of Pryor is our clossary of terms . A handy guide of what everything means and the only glossery or marking and traceability terms you’ll need.
Unlike a 1D barcode that stores data in a line of black and white bars, a 2D barcode stores a lot more data in a grid of black and white squares that can be arranged in either a square or a rectangular pattern. They look a bit like very small crossword puzzles and are often found on packaging, posters and on manufacturing parts. Data is stored both horizontally and vertically, resulting in significantly greater storage capacity than a 1D barcode. 2D barcodes are machine readable and can pass on text or numeric data in the blink of an electronic eye.
A Data Matrix code is the name given to a particular type of 2D barcode as defined by the ISO/IEC 16022 international standard. Each Data Matrix has 2 solid adjacent borders that form an ‘L’ shape. This ‘L’ is called a “finder pattern” and ensures that the code can be read regardless of its orientation.
Data Matrix codes are formed by a series of equally sized squares and so are ideal for marking with dot-peen machines.
Each Data Matrix can store up to 3116 numbers or 2335 alphanumeric characters from the full ASCII range, and this data can even be encrypted for security purposes.
Another key advantage of a Data Matrix is error proofing. Codes can be designed to ensure that even when partially damaged or obscured a majority of data can be recovered from them.
A QR code (Quick Response Code) is another type of 2D barcode, first developed in the Japanese automotive industry, but has since become widely used in advertising applications. The amount of data that can be stored in a QR code depends on the data type and the error correction level. There are four correction levels, the higher the level, the less storage capacity. A QR code is recognisable by three distinctive squares at the corners.
Pryor supplies a range of products for marking, reading and managing 2D barcodes. Data Matrix codes are believed to be the more secure (less hackable) codes and are favoured where high security is deemed important. Pryor’s dot-peen, laser, chemical etching and inkjet machines are all suitable for Data Matrix marking applications. Laser, Inkjet and chemical etching are suitable for marking QR codes.
Alphanumeric refers to alphabetic and numeric characters; the 26 alphabetic characters, A to Z, and the 10 Arabic numerals, 0 to 9

EN 9132 = European (English)
Having a perpendicular corner cut off at an angle to give a less sharp edge.
Chemical etching, also known as electrochemical etching, is a vital process in industries such as Aerospace, prioritizing surface integrity. Unlike conventional methods like hand tools or laser marking, electrochemical etching minimizes surface impact, particularly on softer metals and special steels.
Object for securing a work piece on a machine tool.
A collimator is a device used to align or straighten the path of light beams, particles, or waves. In the context of lasers, a collimator is particularly important. It helps in making the laser beam parallel, ensuring that the light rays travel in a straight line without spreading out.
Collimators consist of optical elements such as lenses or mirrors. These elements are arranged in a way that they effectively capture the divergent light from the laser source and convert it into a parallel beam. This is essential in applications where precision and accuracy are crucial, such as in laser engraving.
For lasers, using a collimator means that the emitted light can be effectively directed towards the target area with minimal divergence or spreading. This ensures that the laser beam retains its intensity and focus over long distances, making it suitable for various applications ranging from industrial processes to medical procedures and scientific research. In essence, a collimator enhances the performance and usability of laser systems by optimizing the directionality and coherence of the emitted light.
A collimator will normally be attached to the end of the delivery fibre of a marking laser, as it enters the scan-head.
The distance between the surface upon which you load your part (the base) and the marking head on a marking machine, or the collet on a press.
The use of male and female dies to create a sunken, readable mark on thin sheet material.
A diode is an electronic semiconductor device with two transmitting terminals; a cathode and an anode. This restricts the flow of current to one direction only.
DPM stands for Direct Part Marking. It is an industry term used to describe permanent marks which are made directly onto the surface of a component or product. All of Pryor’s marking products can be used to perform DPM, depending on the material being marked.
The alternative to DPM is to apply a mark to a label or sticker which is then attached to the component.
Dot Stress products create an impression of a character formed from dots, rather than a continuous line. This reduces stress levels in the component. Pryor offer both Dot Stress, low stress type stamps and Dot stress low stress metal hand stamps
The Dot Stress impression gives an even lower stress level than a Mini Stress impression. In both cases the impressions are made with a rounded edge rather than a sharp edge. This helps to avoid premature cracking, by eliminating the stress concentration at the bottom of the indentation.
The use of male and female dies to create a raised, readable mark on thin sheet material.

It is a Rolls-Royce global document that was compiled for new component designs and will be called out in place of the previous system of JES and EDI specifications. Find out more about the RRES 90003 Specification
Scribe marking is a method of marking whereby a stylus is dragged through the surface of the material to create a continuous line engraved mark.
Sharp faced impressions create a V shaped indent in the material being marked and are suitable for all non-stress critical materials. Due to the shape of the indent, sharp faced impressions are capable of creating a deeper mark with less force. The resulting impression is a sharp, crisp character.
In 1936 the ATA (Air Transport Association) was formed to represent the aerospace industry. The ATA Spec 2000 is an international standard that was subsequently developed to improve communication and information flow between members of the interconnected global supply chain network. Now renamed as Airlines for America, the ATA continues to promote a healthy airline industry in the USA.
This standard is a comprehensive specification that introduced the requirement to identify each part with a unique serial number that enables any part anywhere in the world to be identified as individual and distinct from any other part, however similar that other part may be. The identification method specified is a permanently marked barcode or 2D data matrix code that should remain on the part throughout its entire life. Read more about SPEC 2000
