SPECTRAL MASTERING
With the adoption of software-based color management systems such as ColorSync on the MAC, Integrated Color Management (ICM) on PCs, and the wide use of the International Color Consortium's (ICC) data and file formats, color measurement using internationally accepted scientific standards is now an inherent element of mainstream operating systems. To take full advantage of this exciting new level of precision and accuracy, color data must be traceable to the Commission Internationale de l'Eclairage's (CIE) methodology and colorimetric information base. To comply with CIE standards, color images are analyzed with a spectrophotometer, a scientific instrument for measuring light, and the data that results is transformed using CIE provided tables and formulas. This is the Spectral Mastering process and a device that employs this process is known as a Spectral Scanner.

XYZ OBSERVER MODEL 5B
5B is the world's first spectral scanner, a scientific-grade light measuring system optimized to analyze and digitize images used in publishing, prepress and graphical applications. It is designed to make reproducible observations and generate colorimetric information of the highest quality.

FEATURES The system exhibits excellent spatial, photodynamic and colorimetric characteristics and repeatability, and allows the user to select colorimetric measurement conditions. Final output, CIELAB encoded image files, are saved in the industry standard TIFF format. An integrated Pentium-based computer acts as system host and automates or greatly simplifies system setup, routine measurement procedures, device calibration and communications with network-connected systems. The 5B also creates CD-ROMs containing its distortion free, premium quality spectral masters.

BENEFITS 5B allows the graphical supplier to offer a new and unique high value product, spectral masters. 5B crosses a significant technical threshold by complying with CIE measurement standards and this separates 5B from all other image capture systems or methods. CIE-traceable data opens new markets like artwork identification and authentication and image archiving and preservation. 5B colorimetric output is compatible with and greatly enhances the performance of all color management systems.
