Two Misunderstandings of Color Printing Color Management

Myth #5: There are no big differences between different color management tools

In the current situation, although most of the color management systems are based on ICC files, they may also be different.

(1) Color management software may have different accuracy in color conversion. For example, when creating a property file, some software samples are calculated using only dozens of color samples. Some systems may require thousands of color samples to be calculated. This may result in different color conversions due to the sampling of the color samples. degree.

(2) Color management software may use different methods to perform color conversion between color spaces of different color related devices. In this way, even if the same color sample is used, different color conversion results are likely to be produced.

(3) There is also a big difference in the efficiency of software. When the color management module in some software packages performs color conversion, some close-up special positions need to be selected in the color space to read the color samples to increase the color conversion efficiency; in some software, the color management module may not only obtain color at these positions. If you want to read more color samples in other locations, it is likely to reduce conversion efficiency, but it may improve the accuracy of color conversion.

(4) The accuracy of color measurement equipment is also not the same. When a color measurement device reads a color sample used to create a color device profile, this factor may affect the created profile to a large extent, and this factor may greatly affect the quality of my documents created and Ultimately affect the device's color data ingest or copy effect.

(5) Software packages in some color management systems are designed for the study of experts or researchers. There are more and more complex and specialized settings; some are designed, set up, and used by general users for production. It's easier.

Misunderstanding 6: The device properties file does not have to be changed once it is created
A device profile is a file that describes the performance characteristics of a color-related device that ingests or reproduces colors, and is used in the device to achieve better color ingestion or copying effects. From the front-end scanners, computer screen printers, photo-composing machines, and CTP devices that have emerged in recent years, to printing machines, excellent color management is required to create separate profiles. Once the profile of a color-related device has been established, it does not need to change. It may affect the use of a certain period of time, changes in device performance, changes in printing materials such as ink and paper, and changes in the production process. The established characteristic file is no longer consistent with the actual situation. This requires that the equipment's characteristic file be rebuilt in a timely manner or based on changes in the production conditions, so that the characteristic file is closely linked with the actual situation to ensure the effect of color management.

Myth #7: Color Management System Can Copy Colors Completely
Color management is not a panacea. Even if color management is carried out, copying the original color completely is still not possible in most cases. The purpose of color management is to make the colors between the original and the printed product as consistent as possible. It is determined by the inherent contradiction that the color of the color output device is always less than the color gamut of the color input device. Although the color management system cannot complete the complete reproduction of the color, the proper use of the color management system can ensure the stability and accuracy of the color reproduction of the same manuscript in large quantities, and more importantly, it can ensure as much as possible under different printing situations. The color consistency of prints.

Myth #8: The use of color management systems can extend the range of colors the device can ingest or copy
The color management system generally completes the tasks of color management by calibrating, characterizing, and using the color management module in the software to perform color space conversion in three steps. This process only calibrates the equipment so that it can accurately ingest, duplicate colors, or make the color information as consistent as possible between devices. The range of colors the device can ingest or reproduce does not change and does not increase the color of the device. range.

Misunderstanding 9: The cost of a color management system can only be afforded by large companies
Color management is first and foremost a concept. It needs to be implemented in production, but also related hardware and software tools. It is more important to be recognized by users. However, color management systems do not necessarily need to be affordable by large companies. Huge investments require the establishment of a complete modern color management system, which accounts for only a small fraction of the output of a small company. On the other hand, the color management tools are also different because of the simplicity and price. On the other hand, with the continuous development and maturity of technology, the cost of hardware and software of color management systems is gradually reduced to more users. Affordable limit. If you are worried about the cost of running a color management system, you can make full use of existing employees. Through related training, it is entirely possible that you do not need to introduce special color management personnel, and you can also improve the overall quality of employees. From the perspective of total quality management, Can steadily improve product quality. In this way, the cost needed is affordable for small companies. In addition, the color management effects brought by the color management hardware and software systems at different prices are not necessarily limited to large differences. This depends to a greater extent on the relative quality of the employees using this system. Of course, color management does not necessarily require purchasing color management software and hardware systems. For example, professional companies that provide color management services can also provide color management services on a regular basis.

Of course, the understanding of color management is still deepening, promotion and application of the road is still very long, out of the misunderstanding on the understanding, color management can better serve the enterprise.
