How Rainbow Color Management System Works

The primary task of digital proofing is to solve the accuracy of the digital proofs on the printed color simulation. Therefore, the color management data integration module that controls the print colors becomes the key to digital proofing technology.

In the digital proofing system, the rainbow color management data module is based on ICC, a cross-platform, open standard for color management, and takes the ICC as the standard color management technology as the core of our color management. In accordance with the ICC international standard format, using colorimetry knowledge, according to the actual production needs, using printing standardization process management control data, established a variety of different conditions, a large number of various printing equipment and printing equipment, the precise correction of the ICC Profile , Color feature description file, which determines the color characteristics and compensation methods of the accurate color space conversion of the printer and the color printer. Based on this, the color is accurately edited, calculated, and converted. Thus formed a rainbow color management data module.

The premise of rainbow color management is to use professional optical measurement equipment to help users accurately and accurately measure the printing process parameters, to obtain a complete and reliable printing characteristics of ICC files, and the paper properties of the printer on different digital proofing paper ICC files, through accurate editing And modify, to reduce the color difference between digital proofing and the actual print, rainbow color management of color reproduction index is the average ΔE value is less than 3.0, far higher than the average digital proofing average ΔE value of less than 4.0 indicators, rainbow color management data module has passed The demonstration of the printing industry experts was rated as the color management data module that really meets the printing industry.

Each set of data in the data module is the result of fine-tuning the color space conversion using professional digital proofing software combined with other color management software. Each group of data in the module includes an ICC Profile that accurately reflects print suitability and printability, and also includes a data set that edits and modifies the ICC file based on deviations from physical measurements and deviations from the human eye.

These data centered on commonly used printed materials and processes in China, including offset printing, gravure printing, newspaper printing, etc., are obtained from a large number of in-depth color space simulation experiments under simulated production conditions. The data is accurate and comprehensive, making rainbow colors possible. Management data modules have wide applicability in practical production applications.

Rainbow DiJie Digital Technology Co., Ltd. applies internationally advanced color measurement equipment, output equipment, and RIP for digital proofing. After two years of experiments and explorations, combined with more than ten years of experience in traditional plate making and proofing, we have introduced innovative digital products suitable for domestic printing conditions. Proofing color management data module, combined with a variety of current universal proofing RIP, provides a convenient and practical proofing system for design, advertising, plate making, printing and other users.
