ISO/DIS 12641-1 Graphic technology — Prepress digital data exchange — Colour targets for input scanner calibration
Part 1: Colour targets for input scanner calibration
In the field of graphic technology, color management is the controlled conversion between the different color models. This article discusses the standard ISO 12641-1 for colour targets used in input scanner calibration.
ISO/DIS 12641-1 Graphic technology — Prepress digital data exchange — Colour targets for input scanner calibration — Part 1: Colour targets for input scanner calibration
The ISO/DIS 12641-1 standard specifies requirements for colour targets used to calibrate input scanners. The standard includes three types of colour targets:
- Reflective targets: These are intended for use with reflective originals such as printed matter, photographs, and transparencies.
- Emissive targets: These are intended for use with originals that emit light, such as computer monitors and LCD displays.
- Transmissive targets: These are intended for use with transmissive originals such as film negatives and positives.
The standard also specifies the minimum number of measurement points that should be used for each type of target, as well as the minimum and maximum densities that should be measured.
ISO/DIS 12641-2 Graphic technology — Prepress digital data exchange — Part 2: Advanced colour targets for input scanner calibration
The ISO/DIS 12641-2 standard defines colour targets that can be used to calibrate input scanners. These targets are designed to produce accurate results when scanning different types of materials, including printed documents, photographs, and artwork.
There are three types of colour targets defined in the ISO/DIS 12641-2 standard: grey balance targets, primary colour targets, and secondary colour targets.
Grey balance targets are used to ensure that the scanner is able to accurately reproduce greyscale images. Primary colour targets are used to calibrate the scanner for the three primary colours (red, green, and blue), while secondary colour targets are used to calibrate the scanner for secondary colours (cyan, magenta, yellow, and black).
The ISO/DIS 12641-2 standard also defines how thesecolour targets should be printed and measured. This information is important for ensuring that the results of the calibration process are accurate.
What are the benefits of ISO/DIS 12641-1 Graphic Technology
ISO/DIS 12641-1 is an international standard that provides guidance on the use of colour targets for input scanner calibration. The standard is designed to help ensure that scanner input devices are accurately calibrated, so that the colours reproduced by the scanner match the colours of the original document or image.
There are a number of benefits to using ISO/DIS 12641-1 targets for input scanner calibration. Firstly, the standard helps to ensure that scanners reproduce colours accurately. This is important for a number of reasons, including ensuring that printed documents look as close as possible to their original versions, and making sure that scanned images can be edited without introducing unwanted colour artefacts.
Secondly, using ISO/DIS 12641-1 targets can help to improve the efficiency of scanning processes. This is because the standard provides guidance on how to generate targets that are optimised for use with specific scanners and scanning software. This can help to reduce the time taken to scan documents or images, and can also help to minimise the risk of errors occurring during the scanning process.
Finally, using ISO/DIS 12641-1 targets can help to improve the quality of scanned images. This is because the standard includes requirements for targets that are designed
It facilitates the exchange of information between different systems and software used in construction projects.
