GMG full-flow color management system ColorServer introduction

Increasing digital prepress operations have forced us to automatically convert data from one gamut space to another, and to automatically sharpen and scale images. GMG, a leader in high-end color management processes, has always dedicated itself to the entire process of color management, creating many unique color management technologies. Today, GMG launched the full-process color management system - GMG ColorServer, which integrates the original automatic color separation technology, automatic color gamut space conversion technology, three-dimensional sharpening technology and proportional scaling image technology, fully supports the PDF file format, also The original GMG other color management software can be integrated in the system. At the upcoming China International Print Exhibition in 2006, GMG will fully promote ColorServer, bringing all-process color management concepts and solutions to users in China.

Second, ColorServer main functions and advantages

1. CMYK to CMYK conversion

One of the outstanding features of the GMG ColorServer is the fully automatic CMYK color conversion. It converts CMYK data from one industry standard (such as GRACoL, PSR, ISO, and 3DAP) or one internal standard to another industrial or internal standard to achieve accurate color delivery.

2. GMG 4D color management technology ensures consistent printing

The GMG ColorServer is based on GMG 4D color management technology developed by GMG in cooperation with major European printers and publishers. The software calculates the original and target values ​​directly in CMYK mode without having to pass Lab values. In the conversion process, the black channel attributes of the original data always maintain a very balanced transition, ensuring the consistency of the visual effects output in the target CMYK color space.

3. RGB to CMYK conversion

The pre-pressed RGB data is often in an unedited format. These images are scaled to the final size. The file needs to be sharpened according to the changed resolution, and then the data is separated in the required CMYK color space. GMG ColorServer's hot folder technology enables full automation of these steps. The RGB data put into the hot folder is scaled, sharpened, and color-coded according to the parameter settings of the hot folder. The color separation generated by the GMG is more accurate than the color separation generated using the ICC, and there are fewer problems in printing.

4. RGB to RGB conversion

RGB data can be optimized using the GMG ColorServer. The three initial and target color space spaces, Adobe 98 RGB, sRGB, and ECI RGB, are available and can be freely combined. This is very useful for the standardization of RGB data in prepress.

5. PDF to PDF conversion

The GMG ColorServer also handles CMYK to CMYK conversions and RGB to CMYK conversions of PDF files. When converting a PDF file from one color space to another, the RGB images in the PDF file can be automatically scaled, sharpened, and color-separated. This eliminates the need to turn to image and layout applications during file creation.

6. Accelerate job processing and achieve significant cost savings

In addition to the excellent quality, the main advantages of the GMG ColorServer are the incredible speedup and high-speed automation that is very precisely achieved through the hot-folder technology, and the result is a huge and continuous cost savings.

7. Broad application areas and industries

The flexibility and versatility of the GMG ColorServer have been fully demonstrated by different types of customers, including its own pre-press advertising agencies, export centers and prepress studios, various types of printing companies, and newspapers and magazines. And book publishers.
Third, the typical workflow of GMG ColorServer

PDF files produced by the production company or production department can be imported into the GMG ColorServer for processing. The software can skillfully process the CMYK to CMYK conversion or RGB to CMYK conversion of the images in the PDF file. When converting a PDF file from one color space to another, the RGB images in the PDF file can be automatically scaled, sharpened, and color-separated; the RGB or CMYK images acquired before printing can also be automatically generated by the GMG ColorServer. The conversion, optimization and color separation; while the traditional offset, gravure, digital printing, etc., the final manuscript file can be automatically converted to different color space through the GMG ColorServer to achieve consistent color reduction with different printing processes. For example, if the foreign orders get Chinese printing, the printing machine's color gamut space is different due to the different printing dot enlargement rates. After changing the printing conditions, the color reproduction is quite different, and it cannot meet the requirements of foreign customers for color consistency. GMG ColorServer collects the printing color gamut of two kinds of printing conditions through printing the sample, and then carry on the gamut space to change automatically, can realize the consistency of color reduction easily. The unique and powerful function of GMG ColorServer solves many color problems of printing companies in the face of outside orders.

Third, the actual application of GMG ColorServer

Shanghai Long Ying Color Plate Co., Ltd., as one of the most powerful subsidiaries of Shanghai Jie Long Group, is one of the largest professional platemaking companies in China. The company has digital proofing, CTP direct plate making, digital printing and digital photography and other international advanced technology and plate making equipment. Shanghai Long Sakura is not only responsible for the pre-press design and production tasks of its printing subsidiary's printing business, but also often receives foreign orders from customers in Japan and the United States. Due to the difference in the color space and the printing dot enlargement rate of the company's offset press compared with that of foreign offset presses, the color difference between the halftones of the printed products is large, which requires the prepress staff to perform complicated color adjustment work, sometimes even requiring the original Make a remake. This not only requires high-quality professional and technical personnel, but also consumes a lot of manpower and material resources. At the end of 2005, in the process of purchasing GMG Digital Proof, a GMG digital proofing product, Shanghai Long Sakura learned about GMG's new product, the GMG ColorServer, and tested it with great interest. The test results show that GMG ColorServer can solve the problem that has been plaguing Shanghai Dragon Cherry - the inconsistency of the color reproduction of foreign orders. Therefore, at the beginning of 2006, Shanghai Long Ying Color Plate Co., Ltd. officially introduced the GMG ColorServer. The automatic function of GMG ColorServer is convenient, quick and easy to operate, effectively saving manpower and material resources for Shanghai Dragon Sakura. At the same time, GMG ColorServer's full-flow color management concept integrates the existing workflow and simplifies the entire prepress process.

GMG ColorServer's unique superior features are also regarded by many large-scale plate-making companies and printing companies. They have obtained more mature applications in foreign countries, and are suitable for printing, video, art reproduction, fast printing, printing color space conversion, etc. . GMG ColorServer, as the main product of GMG in 2006, will make its debut at the 2006 China International Print Exhibition from June 14th to 17th, bringing the whole process of color management concept and practical solutions to users in more industries in China. The joy of color management goes on!
