Digital Proofing Development Process and Process Flow (3)

Epson introduced the Epson Stylus PRO7800/9800 eight-color printer specifically designed for digital proofing, and has greatly improved speed, ink and even media based on the original four series printers. HP introduced the new concept Designjet Z2100/Z3100, in addition to the introduction of the twelve-color ink color gamut technology, but also innovatively embedded the use of the Greiner i1 spectrophotometer measurement equipment to improve color management efficiency.

Canon introduced the imagePROGRAF5000/9000. The most prominent feature of Canon is the adoption of the twelve-color ink color gamut technology, and the number of nozzles up to 30,720, enabling high-precision printing.

In order to seize the market of digital proofing, equipment manufacturers are striving to improve technology, reduce costs, so that printing companies to enter the digital proofing threshold is reduced, digital proofing technology to improve and promote the digital proofing further development.

·monitor. Need to screen proofing operation, the performance of the monitor can not be ignored.

For screen proofing, the most important thing for a monitor is its wide color gamut and high stability. So far, the most frequently used screen proofing monitors are Apple and EIZO. The reason why they chose these two major businesses is because their monitors have indeed achieved a large color gamut and high stability. On the other hand, it is due to this. A series of displays of two merchants has passed the authoritative SWOP certification, which means that the use of this monitor for screen proofing is approved, which also gives customers and companies a basis for evaluation.

The monitors currently recommended by Apple as screen soft proofing are APPLE20” CINEMA DISPLAY, APPLE23” CINEMA DISPLAY and APPLE30” CINEMA DISPLAY. These monitors are all high-definition, jitter-free, wide viewing angle, fast response, all-digital connectivity, and perfect integration with PowerMac G4. The outstanding feature is Apple's new technology to meet the needs of the screen for soft proofing.

EIZO's EIZOCOLOREDGECG220, EIZOCOLOREDGECG210 and EIZOCOLOREDGECG21, CG series monitors are mainly used for artwork reproduction, high-end printing and screen soft proofing. Therefore, different types of monitors in the series are suitable for screen proofing. In addition, there are also some big brand businesses such as Sony, which are also starting to enter the soft proofing market.

·measuring equipment. A key step in the success or failure of the digital proofing system is whether the color management is done well, the color management is able to get accurate bit color reproduction, the proofing simulation printing effect is good, if the color management is not done enough, despite the high performance of the digital printer or the display How beautiful the proofs come out, but it still cannot be matched with printing. The importance of color management is indisputable, and the accuracy of measurement equipment affects the effectiveness of color management. Therefore, measurement equipment has become another important object to be improved by merchants.

The measuring equipment that is currently used is X-Rite (it would have been Gelinger, but it is now acquired by X-Rite). The commonly used measuring equipment is the Eye-One spectrophotometer (with different versions), DTP70, The 500 series spectroradiometers also have the latest Eye-One Isis. In addition to a great improvement in accuracy, these devices have also made a series of improvements in terms of color difference formulas, color spaces, etc., making the measurement more accurate and using a wider range of data.

Although there are not many changes in the core of the hardware update, but in many aspects are more complete, to a large extent, adapted to the development of digital proofing.

2, software

Software configuration as a digital proofing system refers to color management software. Currently the most popular color management software is EFI (acquisition of Best, extension of Best's core), GMG, BM, StarProof and Founder photo. Each of these softwares has its own core technology and has its own set of operating methods. However, the purpose is the same. It is to establish the correspondence between the original and printed materials. No matter which software is used, it is very powerful as a color management function, and it also realizes the need for color reproduction.

Regardless of whether it is international or domestic, digital proofing has been used as a new technology to penetrate the internals of many companies. Regardless of how long it takes, digital proofing can always successfully replace traditional proofing, lead printing proofing to a more advanced era. (Finish)
