Digital Proofing Competition Advantages and Methods of Operation

First, the competitive advantage of digital proofing

In the printing field, proofing plays two important functions. First, it allows customers to confirm their proofs with a certain degree of satisfaction. Second, the printing company prints out products that meet the customer's needs according to the proofs the customer signed. The products that can be delivered to customers with high quality and short cycle are the service tenet of the company and an important guarantee for occupying market share. In the development and competition of the market, digital proofing stands out. It not only meets the needs of the development of the printing industry, but also has the advantage of competition in the industry today. The advantages of digital proofing compared with the traditional version of proofs are as follows:

1. Digital proofing equipment is cheap and has low investment.

2. Digital proofing covers an area that is small and no noise contributes to environmental protection.

3. Digital proofing quality is stable. It is not affected by environmental factors, and is not influenced by human factors such as the operator's experience, emotion, etc., and is not affected by the length of the printing process, temperature change, ink K value, saturation, etc. .

4. Digital proofing is easy to operate and saves labor. There are few variable factors in digital proofing. After a good linear calibration of color, one person can operate according to a certain operating procedure (the person in charge can be part-time).

5. Digital proofing costs are low and the cycle is short. Digital proofing supplies only paper and ink, eliminating the need for output film and drying PS version, while at the same time facilitate the customer to modify, eliminating the need for traditional proofing to modify the time and cost of a copy of the first copy of the film and repeat the time. And because BESTColor facilitates the processing of RGB or CMYK picture files, whether it is TIFF, TEPG, EPS, PS and other formats can save the print task, and do a number of times to calculate the output, reducing the error rate, reducing the rework rate. Once the customer confirms proofs, they are issued, printed, and printed, reducing production costs, shortening production cycles, and increasing production efficiency.

6. Adapted to market demand, to achieve off-site proofing. BESTColor Digital Proofing System uses standard ICC-based color management technology. The ICC has the advantage of being able to print-related data, such as ink hue, dot expansion, paper color, etc., can be stored in a very small file, and the CC file can be named as required. This file is very small and can be disseminated by e-mail to any part of the production process. The user who obtains this file can easily produce high-precision color proofing and can maintain the exact same color as the final print. This new technology adapts to the development of the market, promotes the cooperation of communication and digital printing, and realizes off-site proofing and off-site printing.

7. Digital proofing color management is intuitive, and the most important thing is that digital proofing proofs are proofs on the print. Digital proofing uses six-color inks. It has wider color gamut than printing inks in the color gamut. The color range is relatively large. The ink color is stable, the printing effect is delicate, the color saturation is good, and the texture of proofs is strong, especially digital proofing. After many years of development and improvement, the color management system has basically matched the printability. The Epson-BESTColor Digital Proofing System we use uses the advanced level of ICC color management technology as the core of the system. Users can accurately copy the printed colors through the colorimeter and ICC file generation software, relying on BESTColor. Control the color transfer throughout the plate making process and provide standard proofs for the printing process.

Second, the digital proofing operation method

1. Driven by the digital proofer BESTColor, the digital proofs are printed using the electronic documents recognized by the Global Color Alliance. The digital proofs are then measured by the Spectrophotometer under the PrintOpen Color Extreme software.

2. Using the electronic document accepted by the Global Color Consortium, a laser image-setter was used to print a piece of paper. The conventional proofs were printed on an offset press in accordance with standards, and then the traditional proof data was measured by a Spectrophotometer under the PrintOpen color correction software.

3. The data curve of the digital printing sample and the data curve of the offset printing proof are placed in the BESTColor, and the ideal digital image (digital proof) is obtained by calculation of the proofing. This digital proof is basically the same as the offset proof. Note that the adjusted data curve is stored.

Digital proofing can mimic offset proofs of different papers. The key point is that the offset proof data to be tested must be accurate.

Digital proofing must have strong technical support, not only the application of computer technology, but also the application and mastery of color management technology. The digital proofing machine itself is suitable for the color management system of special paper and special ink. It may not be suitable for the situation of our company. Therefore, we should do two kinds of tests: one is standardized test of printing; the other is the color management system through digital proofing. Combining the output effects of various color devices, and testing out their own digital integration files on this platform, organically combining all parts of the production process of printing plate making, printing out proofs suitable for their own printing process requirements.

Digital technology instead of traditional technology is the direction of development. The foundation of CTP technology is to solve digital proofing first, and color proofing is no longer just used to check the quality of the plate-making film, at the same time, the task of design proofing, color proofing, and plate proofing is frankly accepted. The subject of digital proofing and the subject of imitation are printed matter, and the production of good prints requires strict printing process support (standardized printing), combining the experience of traditional printing processes with modern digital technologies and color management techniques. The opportunity to promote the development of traditional printing technology is the mission that history has given us. With the gradual withdrawal of traditional proofers, digital proofing will soon be recognized by people. The spring of digital proofing has come.
