As an entry-level certified cosmetic packaging for printing standardization, G7 certification can easily and quickly calibrate the color of printing equipment by calibrating the gray balance in production practice, so it has been widely accepted and recognized by more and more companies in the industry. . At the time of initial certification, G7 certified companies will be recommended to purchase the officially developed G7 calibration tool Curve for calculating the RIP compensation curve, so companies that pass G7 certification will basically have a set of Curve software. Although there are more and more CTFs supporting G7 calibration on the market, the earliest officially produced software Curve is still the most accurate and popular G7 calibration software. CTP However, unfortunately, the interface and manual of the software in English make many people in the industry want to enter and not want to learn, but the G7 expert training course of Hong Kong APTEC as the source is rarely involved. The depth of the software is applied to paper packaging . In fact, quite a few G7 certification experts do not mention or understand how the software is applied. This way, a lot of enterprises have software does not use an objective or a bad situation, and if the bad Curve software, how about the popularization and application of good G7 technology? Events The author is a senior professional G7 certification expert, using the current industry's most popular Curve3 software as an example font , to share with you how to use the Curve3 software. Policies and regulations The interface first met the printer tour First, when the software is opened, the first panel is the settings panel, followed by ink, calibration, calibration and VPR virtual printing five panels, which are more commonly used to set and correct the panel. X-Rite In the "Settings" panel, the CD is printed . The default is to calculate and compensate the curve according to the G7 method. Therefore, if you use the G7 method, there is no need to modify it here; however, it should be noted that if you need to press the TVI (Tone Value Increase value) When adding the method of increasing the dot gain, you can select the TVI option. At this time, the six curve cuts specified by the ISO12647-2 standard will be popped out , from which we can select the corresponding curve as the target value according to different color plates. For example, ordinary coated paper printing generally selects C curve for CMY tricolor according to ISO12647:2007 standard; B curve for K (note that the dot value calculated by Curve software is based on CIEXYZ, and is calculated based on density based on conventional calculation. The value of the dot is different); Special Ink is mainly based on a simple and common calculation method of DeltaE to correct the color of non-CMYK, and the actual situation is less used. Lekai two glue Different calibration methods are selected, and the software in the upper right corner of the software will indicate the current software application mode. label If you need to archive, you can fill in the information panel below the die stamping creasing when times G7 tests, such as printing presses, ink, paper and printing types. rubber products Airbrush Zhongshan Okay Technology Co., Ltd , https://www.okaygroup.com
