The characteristics of the promotion and development of digital proofing technology

1. Standardization is the application basis of digital proofing

Color management technology is still the key to digital proofing applications. Due to the wide variety of printing materials such as ink and paper, the printing process is different. Color profiles that reflect printability are also different. The quality standardization of various prints is a basic condition for the smooth application of digital proofing. Therefore, in the process of digital proofing promotion, the dataization and standardization work of traditional printing process management needs to receive sufficient attention. Only in this way, digital proofing will have practical application value.

2. Digital proofing color correction ability

The color management technology of digital proofing has been greatly improved in the past few years. In recent years, the US IPA (a professional organization for prepress design, printing and publishing, packaging and other fields) has analyzed various digital proofing softwares in today's printing field. After comparing digital proofing products from 30 different manufacturers, it found that Can achieve a small color difference, visible color difference is no longer the main problem of today's digital proofing technology. In order to achieve smaller chromatic aberrations, many software companies have introduced new cycle color correction tools. For example, EFl Best Color has introduced a closed-loop correction tool using ICC technology standards, which can realize RGB, CMYK or more in EFI ColorProof XF. Cyclic correction of channel high fidelity colors. At the same time, GMG also launched a cycle color correction tool based on 4-color printing. All major digital software companies have greatly improved the color-catching ability of digital proofing.

3. Digital proofing color solution

Another development in digital proofing technology is better support for spot colors and multi-channel high fidelity digital proofing. In packaging and printing companies, digital proofing will face the test of strict spot color proofing. First of all, in the color engine of the digital proofing software, major software companies have launched a color library that meets the PantoTie digital spot color standard. At the same time, the multi-color high-fidelity color engine EFI ColorProofxF has been developed to support the input and output of 6-color multi-channel images. The latest software from ORIS and GMG can also output and print 6-color high-fidelity images, which greatly meet the needs of packaging and printing companies. The hardware used for digital proofing is roughly divided into two categories: general-purpose inkjet printers and specially developed digital proofing output devices. China's current widely used series of large-format printers such as Epson, HP, and Canon. It has an ink gamut that completely covers 4 colors of printing, but in spot color proofing, certain colors (such as fluorescent orange, green, etc.) are outside the ink gamut of inkjet printers. Currently, digital proofing equipment based on ordinary inkjet can Restore 80% to 85% Pantone spot color, Epson's latest Epson Stylus Pro 7910/99l0/7910 Pro/9910 Professional 11-color large format printer expands the color gamut of reproduction. Other specialized devices, such as Kodak Approval XP4 and Rich±'s Final Proof, have a wider color gamut, but such systems are more expensive.

4. Screen soft proofing is the new force of digital proofing

The expansion of digital proofing to the soft proofing of the screen is a future development direction. In the US IPA evaluation, many manufacturers have provided a new generation of screen soft proofing solutions. DALIM's Dialogue and ICS's Remote Di rector system have very good color performance. They can be used on Apple or EIZO color monitors. Accurately express 4 colors and spot colors. Can predict. Soft proofing of the screen will become a new force in color proofing.

5. Color standards and optimized color correction tools

After the digitalization of the printing industry, many companies' digital proofing systems face new challenges, that is, printing companies have larger working groups, the network environment is more complex, and there are more people. The whole system needs to support the common ICC color flow, many people. Work together in multiple locations. At the same time, with the development of inkjet printing technology and digital proofing materials, printing companies have new requirements for the color of digital proofing. Many customers hope that their products can achieve color uniformity, achieve color standards at home and abroad, and better complete overseas. The production of orders, better communication with customers, sub-printing points, and out-of-process points to achieve digital color in line with international standards. In order to meet the needs of users, major software companies have also introduced optimized color correction tools that can achieve color uniformity of multiple printers. EFl's colorProof XF 3.0 software directly supports color standard calibration, and can achieve color uniformity and consistency adjustment of multiple printers through embedded tools, which greatly meets the higher requirements of color printing companies. Many companies use PDF files and ICC profiles directly to complete digital proofing, so support for PDF files and lCC common standards has become a major reference point for enterprises to choose digital proofing systems.

6. Custom modular products

As a necessary part of modern printing, digital proofing is still changing to meet the needs of printing companies. Every user, whether it is a prepress company, an agency, a printer, or a photography industry, has different requirements for software solutions. Major software companies have introduced modular products that make it easier for printing companies to customize. Customization will be a trend in the future of digital proofing systems.

7. True dot proofing technology

The biggest advantage of the real dot proofing technology is that you can directly use the lbit TIFF file after the imagesetter or CTP RIP for color proofing. The whole process does not go to the network, does not re-hang the network, and really retains all the output information. This proofing method greatly enhances the security of digital proofing, and also incorporates digital proofing into the platemaking workflow of the printing company. Because the input file of the real dot proofing technology is the lbit TIFF file after RIP, the user does not have to worry about various RIP output traps and directly proof the result of RIP.

8. Digital proofing with digital presses

In recent years, digital printing machines have entered the traditional printing enterprises. The original intention of traditional digital printing companies to introduce digital printing should be to supplement the traditional offset printing. It is used for printing short, fast, on-demand, personalized and special jobs, but the operating rate is insufficient. Therefore, digital proofing, as the main application of digital printing in traditional printing enterprises, has improved in terms of quality, efficiency and cost.

9. Digital proofing enhances versatility

The development of digital proofing technology will be streamlined, and the improvement of versatility and simplicity is also a hot spot for major manufacturers. The new generation PDF1.6 version of the document has better security and complete printing information, fully meet the requirements of modern printing. More and more people will use PDF to directly perform digital proofing.
