With the full popularity of digital proofing applications, more and more users in the printing industry are benefiting from their high efficiency, low cost and high quality. At the same time, the demand for depth and breadth of digital proofing is increasing. It is expected to be a common commercial contract proofing, and includes a complete solution for layout proofing, blue paper proofing, newspaper proofing, screen proofing, remote proofing, and even packaging proofing.
The replacement of traditional proofing by digital proofing has become an irreversible trend, and many digital proofing system suppliers have seized this opportunity to continuously introduce a new generation of digital proofing technology to the market.
1. hardware
1 digital proofing machine. The market demand for digital proofing machines is fast, accurate and precise. Fast, is an important reason for enterprises to choose digital proofing. This requirement is not finalized. Quasi, that is, the accuracy of the color, the printing process is generally a color reproduction process. Fine, that is, the degree of precision, that is, the resolution is high, the resolution determines the clarity of the proof, and is also a key factor for the customer to judge the signature.
In response to the current market demand for digital proofing, well-known brands such as Epson, Hewlett-Packard, and Canon have introduced a new generation of digital printers. Epson has launched the Epson Stylus Pro 7910/9910/7910 Professional/9910 Professional 11-color large format inkjet printer for digital proofing. It is based on the original 4-color printers in terms of speed, ink and even media. Great improvement. HP introduced the new concept of the Designjet Z2100/Z3100 large-format inkjet printer. In addition to the 12-color ink large color gamut technology, it also innovatively incorporates a spectrophotometer measuring device using the Gringda il technology to improve color management. effectiveness. Canon's imagePROGRAF 5000/9000 uses a 12-color ink color gamut technology and uses a maximum of 30,720 nozzles for high-precision printing.
In order to seize the market of digital proofing, equipment manufacturers are striving to improve technology and reduce costs, thus reducing the threshold for printing companies to enter the digital proofing field.
2 display. For screen proofing, the most important thing is that the display color gamut is wide and stable. So far, most of the monitors used for screen proofing are Apple and EIZO products. Their monitors have achieved large color gamut and high stability, and since these two series of monitors have passed the authoritative SWOP certification, they are ready to use. Proofing on the screen is approved. In addition, Sony and other branded displays have also begun to enter the screen soft proofing market.
3 measuring equipment. Measuring equipment is the key to verifying the accuracy of digital proofing color reproduction, and the accuracy of measuring equipment affects the effect of color management. Therefore, measuring equipment has become another important object to be improved.
The measuring devices currently used are mainly X-Rite products. The commonly used measuring devices are Eye-One spectrophotometer, DTP70, 500 series spectrodensitometer and the latest Eye-One Isis. In addition to the great improvement in precision, these devices have also been improved in principle, such as color difference formula, color space, etc., making the measurement effect more accurate and the data used in a wider range.
2. software
The software configuration of the digital proofing system refers to the color management software. Currently the most popular color management software is EFl, GMG, BlackMagic, StarProof and Founder Photo. These softwares all have their own core technologies and operations.
At present, there are many digital proofing softwares in China, mainly introducing the following types.

The company uses closed-loop correction technology to provide users with a consistent color proofing solution.
2EFl Best ColorProof XF
In the current commercial printing field. EFl's Best proof color management software is the most widely used. Since 1999, Germany Best (acquired by EFI) has launched the Best Color digital proofing system based on ICC color management technology, the general inkjet printer also has the performance of outputting high-quality digital proofs, making the digital proofing system Performance has been completely changed.

4 Founder Photo 4.OC
Beidafang is the first in China to launch a digital proofing plug-in based on Founder Century RlP. The Founder Photo V4 0 Business Edition launched in 2007 is a true dot digital proofing software after RIP. Combining Founder's 30 years of experience in the RIP field, by reading the net data in lbit TIFF, it is possible to finely control the size of the printed dots, simulate the printed dots, and reproduce the printed colors.
5ICS Remote Director System
