- RAL, Pantone, HKS
Frequently used special colours are compiled in these colour scales.
- Read/write devices
In many applications, the transponder must remain on the object to be identified when data on the transponder is saved or modified. Transponders with this function can be re-programmed and are called read/write transponders, memory cards or storage modules. Read/write devices are used to call up the information from tags and save information in the tag store. In this, a general differentiation is made between stationary read/write units (e.g. in a gate) and mobile read/write devices (MDE, handheld).
The reading device which records the data on the transponders, for example. This occurs via radio waves.
The decoding, extraction and depiction of the actual data content which is transmitted by the transponder in addition to the bits for format definition, monitoring and error management.
- Reading device
Also called a reader, send/receive unit or read/write device. Antenna which transmits to the transponders and reads its data. Most reading devices are also writing devices. They can use radio signals to save data to writable transponders.
- Reading range
This is the maximum distance over which the antenna of a read/write device and a transponder can communicate effectively. The reading range can be influenced by the alignment to the antenna and by ambient conditions, for example.
- Reading rate
The maximum speed at which data can be read from a transponder, expressed in bits or bytes per second.
When the individual colours in multicolour printing are printed exactly on top of each other or the printed labels are cut fitting exactly.
- Rejection level/separating force/release
The release value is determined by the adhesive and the siliconisation in particular. Especially when the labels are dispensed mechanically, easier repellance has been proven in the past. It is measured as the separating force needed to pull off the silicone paper behind the adhesive-coated upper material.

Marginal perforation (transport perforation) in the substrate. (cf. Perforated edge labels)
In self-adhesive labels, this refers to the condition under which the labels can be removed from a substrate.
- Removable adhesive
Self-adhesive with relatively low final adhesion. Adheres strongly to the adhered surface, but can be removed again within a short period.
A parameter which shows how many points can be created on a specific area. Printer resolution is measured in dpi and can be different in the X and Y directions, depending on the type of printer. In scanners, however, resolution (known as optical resolution) is a parameter for the readability of a barcode. In code pens, distance scanners and slot readers, the optical resolution (related to a standard distance), can be for example 0.15 mm, 0.25 mm or 0.38 mm
RFID is a technology for contactless data transmission on the physical basis of electromagnetic alternating fields, i.e. radio waves. The core of RFID technology is an RFID transponder. This tiny computer chip with an antenna is applied to various objects and contains a numerical code, such as the electronic product code (EPC, see entry). The numerical code is read using a reading device.
- RFID tags
RFID tags are also called transponders. They consist of a chip with a simple integrated processor, antenna and associated memory. A wide range of forms is possible, e.g. as coins, discs, labels, stickers, plastic cards, keyrings etc. RFID tags are divided into active and passive transponders.
- Rotating cutting die
All tools which rotate and are used for cutting in label printing machines.
