In recent years, the printing industry's requirements for color have been paid more and more attention, and the importance of color processing processes such as special color ink production and printing has also increased. In order to meet the requirements of speed, quality and market value, the industry must carry out correct color management and transmission through accurate color evaluation.
The traditional ink industry and printing industry still mostly use human eyes to determine and manage colors, but the influence of the difference between the light source, working environment and human eyes often makes human eyes unreliable, so it must be Ding Qi to measure color samples and carry out color management. The filter-type color difference meter currently on the market has been gradually replaced by a spectrophotometer, because the former cannot avoid the problems of its own long-term stability and the exchangeability between machines, so it has been changed to a more advanced one. Spectrophotometer to measure the color. The high-tech spectroscopic technology can not only greatly improve the exchangeability between different models and different brands, but also have the same price and color difference meter.
In addition to the standardized colorimeter, a common color difference formula, such as CMC or CIE94, and a reasonable tolerance range should be used as a color communication channel between upstream and downstream. At the same time, with the latest fluorescent screen display and correction technology, the difference between different fluorescent screens can be controlled below CIE0.5, plus a digital color swatch system, users can create, change and transfer the images and colors And the processing manufacturer can also send the digitalized color samples for confirmation and get the correct instructions for color adjustment immediately. As a result, the desire for physical color samples can be greatly reduced or even not used to confirm the color.
With the rapid development of the electronics industry, information globalization is no longer out of reach. In particular, the trend of computer direct plate-making / printing is sweeping the global printing industry. In the future, it is expected to be used for transnational printing and publishing through computer information transmission. Therefore, accurate computer analysis of data is absolutely necessary. We believe that the ink and printing industry will also follow the trend of the times and move towards instrumented color management and color transmission and communication of data, thereby improving product quality and meeting the needs of international market orientation.
