Analysis: ICC characteristic curve and RIP color management

The function of RIP software is to reproduce the digital pattern on the fabric. As mentioned earlier, color management is a combination of software and hardware, automatically and uniformly manage and adjust colors in the system to ensure the consistency of colors throughout the process. For RIP software, color management is also essential. The color management of the RIP software is mainly realized by embedding the ICC profile. The ICC characteristic curve file provides the color management system with the necessary information needed to convert a device's local color data (such as the color gamut that a device can generate or obtain) into a device-independent color space.

Generally, RIP software manufacturers preset some ICC characteristic curve files in their own software, and the color management is performed by the ICM color management module. But this can only meet the needs of general users, far from meeting the requirements of professional users. In addition, some companies or enterprises have produced specific ICC characteristic curves in order to print satisfactory results, and added them to the printer driver, but this is only the calibration and characterization of color management, and the most critical Convert.

A complete color management system should include printing images, displays, inkjet printers, inks, fabrics, software, etc. To obtain accurate colors, color management, linear calibration, and the generation of ICC characteristic curve files for specific fabrics, models, and RIP software are required. Changing any of these factors will change the output. Color effect. Therefore, an excellent RIP software can be embedded in the customer's ICC characteristic curve file, but also requires customers to be able to make their own ICC characteristic curve file.

The production of ICC characteristic curve files requires special hardware and software, such as X-rite's DPT41 colorimeter and its Monaco Proof software. After making the ICC characteristic curve, it should be imported into the output profile of the RIP software (Output Profile) to achieve the purpose of color management. However, it should be noted that after the color management is done, items related to color management must not be modified at will, such as the resolution in the print mode, the ink channel (such as CMYK, CMYKLcLm, CMYKOrGr, etc.), ink droplet size, and ink output Volume, print pass number, print speed, etc.
