Measuring and defining colors
Visible colors can be composed of: hue, saturation, and brightness. Hue The intensity of one or two colors of light with the largest amount of RGB trichromatic light. When the RGB amounts are equal, the color becomes unsaturated, appearing gray or white, and the luminance is the RGB light wave stimulating the intensity or wave height of the eye-sensing cell. These characteristics can be stacked by some "discs" out of a three-dimensional color model, and the change in the circumference of the disc is described as the hue moves from the bottom up to increase the brightness of the disc. Each disc moves outward from the center to increase saturation. This model is - irregular, because the eye is sensitive to different colors.
Each device has its own gamut space, and some colors can be seen on the screen but cannot be represented by the output device. This is because of the inconsistency in the public space of the screen and the output device. Agfa CMS can connect and match two public spaces to solve the problem of color conversion. When the screen color is used to simulate the printing color, a method can reduce the incapable color space to a representable color space, change the color of the surrounding environment, and utilize the relationship between the eyes and the brain to simulate different color gamuts. Between the results, so the latter is more a winning method that can make all color output devices have a certain color simulation capabilities.
Digital Proofing Application
Existing digital proofing technology has been able to meet most of the general users. They mainly pursue speed, stability and cost effectiveness. These three aspects of performance digital proofing are obviously much better than traditional proofing. Examples of users include general books, magazines, and textbook printing.
For high-end users, although the above three major advantages can not fully meet them and color quality is the most important requirement, precisely because of the stringent requirements of these users, a layout usually requires multiple modifications in the production process, and many of these A variety of users, such as advertising agencies, have begun to use digital proofing as a TESTPROOF (draft). In the process of modification, digital proofing has been used until the modification is completed and then a traditional proofing is done. This is to save a lot of repeated proofing costs.
Is it possible to draw a conclusion in the final part of this introduction: Is digital proofing mature? How to choose equipment? Different users will have different answers depending on the importance of each feature of the digital proofing described above to individual users. The above introduction hopes to provide some references for everyone. The last thing to be pointed out is that today's digital proofing technology has reached a certain degree of practicality, but users must pay attention to the cooperation of software and hardware in selecting equipment, in order to achieve the best results.

A teapot is a vessel used for steeping tea leaves or an herbal mix in boiling or near-boiling water, and for serving the resulting infusion which is called tea. Dry tea is available either in tea bags or as loose tea, in which case a tea infuser or tea strainer may be of some assistance, either to hold the leaves as they steep or to catch the leaves inside the teapot when the tea is poured. Teapots usually have an opening with a lid at their top, where the dry tea and hot water are added, a handle for holding by hand and a spout through which the tea is served. Some teapots have a strainer built-in on the inner edge of the spout. A small air hole in the lid is often created to stop the spout from dripping and splashing when tea is poured. In modern times, a thermal cover called a tea cosy may be used to enhance the steeping process or to prevent the contents of the teapot from cooling too rapidly.
