The full name of the C-Fit software is i-ColorQc C-fit, which is a software used by Fujifilm to apply color conversion. It was mainly used in the Japanese market with a market share of more than 40%. After a great success in the Japanese market, Fuji Starlight introduced it to the domestic market, and also expects it to bring about a new pre-press technological revolution. At the Shanghai All India Exhibition held in November last year, the scene was a bit deserted because not all pre-press equipment vendors participated. Software has also become a new highlight of the exhibition. The main functional modules of C-Fit are RGB picture color optimization, lossless conversion of RGB picture to CMYK picture color vision, automatic management of PDF file content color conversion output and so on. As a trial company of this product, I have realized the powerful functions of the software in advance, and then let us feel the magic of C-Fit's color conversion.
On the main interface, there are General, Settings, and Syetem function menus, and there are many function modules under each menu. We will not introduce them one by one. Here we mainly introduce several major feature modules of C-Fit software.
1. Image optimization module: to achieve automatic optimization of RGB image quality
The Imageoptimization module contains the Image Intelligence technology that Fujifilm has long used in the printing industry. Like the digital camera settings, it can intelligently analyze the scene where the picture is located and make individual color adjustments according to different scenarios. Through the use of Face Detection, Skin Smoothing, Light Source Recognition, Exposure Correction, White Balance Adjustment, Sharpness Enhancement and others With some processing, you can optimize the quality of the image, and all this is done automatically.
Second, RGB to CMYK conversion module: to achieve visual lossless conversion of RGB images to CMYK images
For the conversion of RGB images to CMYK images, it has always been a problem in the industry. Fujitsu has developed Perceptual1 and Perceptual2 compression modes for this problem. The use of Color Appearance Mapping technology allows users to convert RGB images into CMYK images. At the same time, the visual perception of the RGB image is kept to the maximum, which ensures that the color of the image is always kept in the best state when the source file is converted into a printed image.
3. PDF document processing module: analyze the elements in the PDF document and finally convert it into the printing color space
1.RGB to CMYK
â‘ The processing of RGB images in PDF files uses Fuji's unique compression technology to convert the images from RGB source space to CMYK target space.
â‘¡ The processing of the text in the PDF file uses Fuji's unique compression technology to convert the RGB text to CMYK space.
â‘¢Limiting the total ink volume The black ink starting point and total ink volume are limited and the black channel curve is set for printing characteristics.
2.CMYK to C'M'Y'K '
â‘ Processing of CMYK pictures in PDF files (Device Link)
Use Fuji's unique compression technology to convert pictures from CMYK source space to C'M'Y'K 'target space for Device Link matching.
â‘¡The processing of the text in the PDF file uses Fuji's unique compression technology to convert the text into the CMYK color gamut space, and can preserve the colors such as monochrome, K100% and RGB100%.
â‘¢Limiting the total ink volume The black ink starting point and total ink volume are limited and the black channel curve is set for printing characteristics.
4. Setup Tool: Pre-judge the result of image conversion
Browse the pictures through the Setup Tool tool, you can pre-judge the effect of the pictures that need to be converted in Preview, and you can directly see the results of RGB optimization and RGB conversion to CMYK by calling different work subpoenas. In addition, the changes in RGB picture values ​​can also be seen at a glance. For the pictures that have not yet met the requirements after conversion, you can adjust the color by calling Tone Curve channel curve adjustment and Color Correction.
The above are the main functions of the C-Fit software. The software is used in the form of Server and Client connection and does not limit the number of Clients. All file submissions are processed in a hot folder way, which improves the image quality while improving Image processing efficiency. In 2007, C-Fit won the American PIA / GATF (American Printing Industry Association and Graphic Arts Technology Foundation) Technology Innovation Award, which is also the highest praise for pre-press software, looking forward to C-Fit bringing the technical revolution of image color conversion.
(Note: The PIA / GATF "Inter Tech Award" was founded in 1978 to make people pay more attention to and understand advanced printing technology, and to commend technological innovation with outstanding performance in the printing industry. The selection of the winners is made by a complete (Completed by an independent, anonymous anonymous jury composed of celebrities in the printing industry).
