The aim of colour calibration is to measure and/or adjust the colour response of a device (input or output) to a known state. In International Color Consortium (ICC) terms, this is the basis for an additional colour characterization of the device and later profiling. Colour calibration is a requirement for all devices taking an active part of a colour-managed workflow.
Measure luminance and colour of white point and black point using an external sensor and adjustement of the LUT for white point, black point (or Red, Green and Blue point). Tuning of gamma curve (gray shade control).
Creation of a ICC profile for the operating system (PC/MAC)
ICC profile is a set of data that characterizes a colour input or output device, or a colour space, according to standards promulgated by the International Color Consortium (ICC). Profiles describe the color attributes of a particular device or viewing requirement by defining a mapping between the device source or target colour space and a profile connection space (PCS).
The 3D LUT Colour Emulation feature of the SpectraView Series can take the ICC profile of any device, e.g. printer, and through uploading via the MultiProfiler software application, define the monitor gamut to that specific ICC profile.
sRGB (Standard RGB)
C olour space for colour accurate large format display applications. Perfectly matched to NEC public displays
The L*a*b* system defines the colour space with a dimension ‘L’ for lightness and ‘a’ and ‘b’ for the colour dimensions based on non-linearly compressed CIE XYZ space coordinates. Changes in colours are similar to human visual perception abilities. It allows precise table profiling and is perfectly suited to exceptionally accurate 14-bit LUT hardware calibration capability of the SpectraView series.
Other RGB spaces
The integrated 3D LUT with colour emulation preset within the SpectraView and SpectraView Reference products, can be used to transform the colour space of the monitor to emulate that of the printer, or other colour workflow device. The 3D LUT is a three dimensional table that maps colours into a different colour space. The Colour Processing Engine in SpectraView monitors allows complex colour gamuts such as those of colour printers to be emulated on the monitor directly. This allows print previews to be performed with applications that do not support this feature directly. The MultiProfiler application can easily load ICC Profiles into the 3D Look Up Tables.
Experience the very best in colour image quality with the latest generation of state-of-the-art 10-bit P-IPS technology, with exceptionally wide viewing angle, widest colour gamut available (107% AdobeRGB colour space coverage and 98 % size) and absence of colour shift. The true benefit of a wide colour gamut display is particularly visible when combined with 10-bit panel, since potential colour banding or visible grayscale steps are eliminated.
The bundled calibration and profiling software package, SpectraView Profiler, allows precise and straightforward 14-bit per RGB channel, calibration of brightness, white point and luminance and the creation of 16-bit ICC profiles for Apple and Windows systems.
With 16384 tonal values per colour, the Profiler enables an almost step-less and, in turn, considerably more precise gradation adjustment than is the case with conventional software calibration. The finest gradations and grayscales can be displayed with extraordinary precision and clarity. This ensures that the colours seen on the screen match the printer.

SpectraView award-winning models featuring IPS panels have recently added FOGRA PreCert Class Aapproval to their many accolades which is the print industry benchmark for colour accuracy. As well as satisfying the print industry benchmark FOGRA PreCert requirements, SpectraView displays can also be used as part of ISO approved pre-press and soft proof systems. Two ISO standards have emerged to serve the soft proof industry in comparing colour proofs: ISO 3664:1996 and ISO 12646:2008
