What is ISO 12641-2 - Scanner colour calibration about?
During scanner calibration, measuring tables help characterize the specific colour reading capabilities of a scanner. ISO 12641-2 defines a framework for advanced reflective and transmissive layouts and colorimetric values of targets for use in the calibration and characterization of image capturing devices.
ISO 12641-2 defines a framework for target creation and data reporting. This framework can be used for both ISO defined and custom targets for both reflective and transmissive use.
ISO 12641-2 defines the layout and colorimetric values of targets for use in the calibration of a photographic product/input scanner combination (as used in the preparatory process for printing and publishing). One target is defined for positive colour transparency film and another is defined for colour photographic paper.
NOTE: Self-emissive targets are not covered by ISO 12641-2.
Who is ISO 12641-2 - Scanner colour calibration for?
ISO 12641-2 on scanner colour calibration is useful for:
- Graphic designers
- Photographers
- Print media / publishing
- Software companies
- Industry designers
Why should you use ISO 12641-2 - Scanner colour calibration?
Scanners may contain singularities that make them unique from one another and create colour differences. Based on the demands for higher quality from scientific institutions, museums, art and cultural heritage archives, and special public administration applications for ID-documents, a need was recognized to achieve a better scanner colour characterization. Advanced target designs require more patches for an enhanced sampling of saturated and pastel colours (especially for archiving applications). They offer chances for improving the analysis of non-linear scanner performance. ISO 12641‑ 2 specifies the requirements for advanced colour targets for input scanner calibration.
ISO 12641-2 provides you with general requirements and provides exemplary transmissive and reflective targets. Self-emissive targets are covered by this document if they are designed to simulate the targets using transmission of light through an optical filter.
ISO 12641-2 targets are capable of calculating a larger colour spectrum, resulting in more measurement data being readily available, and increased target accuracy.
