Digital proofing efficiency

The extensive use of computers and various software in the pre-press field has promoted the rapid development of pre-press school operations. The transition from DTP to CTP is getting faster and faster. Printing has also become an important way of copying and disseminating information. As electronic publishing and other information dissemination methods of online publishers are bound to be fully digitalized and networked. Digital technology will not only change the printing process and workflow, but also redefine the function of proofing, because regardless of the development of prepress and printing technologies, color proofing is required as a credential between customers and printing companies as prepress and printing. The exchange between us is also inseparable. Therefore, the concept of proofing is not a new concept, but it injects new technologies, new connotations and new solutions.
First, the competitive advantage of digital proofing In the field of printing, proofing plays two important functions. First, it allows customers to confirm their proofs at a certain degree of satisfaction. Second, the printing company prints in accordance with the customer's proofs. The product to come. 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. Digital proofing has a small number of variable factors. After a good linear calibration of color, one can operate according to a certain operating procedure.
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 graphics files, TIFF, TEPG, EPS, PS and other formats can be used to save the print job and achieve multiple calculations at once, reducing the error rate and 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 core of the world-leading ICC color management technology. Users can precisely copy the printed colors by using the colorimeter and ICC file generation software, relying on BESTColor. To control the color transfer throughout the plate making process and provide standard proofs for the printing process.
Second, the digital proofing method of operation 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 King's 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.
