Digital proofing technology to enhance and develop the characteristics presented

1. Standardization is the basic application of digital proofing

Color management technology is still the key to digital proofing applications. Due to the variety of printing materials such as ink and paper, there are differences in the printing process. The color profile that reflects printability also varies. The quality standardization of various kinds of printed matter is a basic condition for the smooth application of digital proofing. Therefore, in the process of digital proofing promotion, the dataization and standardization work involving the 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 capability

Digital proofing color management technology has greatly improved in the past few years. In recent years, the United States IPA (a professional organization for prepress design, printing and publishing, packaging, etc.) has analyzed a variety of digital proofing software in today's printing industry, and compared it with 30 different manufacturers' digital proofing products. Both 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 a smaller color difference, many software companies have introduced a new circular color correction tools, such as EFlBestColor introduced a closed loop correction tool using ICC technology standards, through this tool can be achieved in EFIColorProofXF RGB, CMYK or multi-channel high-fidelity color Cycle correction. At the same time, GMG also launched a color correction tool based on four-color printing. The major digital software companies have greatly improved the ability of color proofing.

3. Digital proofing spot color solution

Another development of digital proofing technology is to better support spot color 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 proofing software of the digital proofing software, major software companies have introduced color libraries that meet PantoTie's digital spot color standards, and have also developed multi-color high-fidelity color engine EFIColorProofxF to support the input and output of 6-color multi-channel images. The latest software released by ORIS and GMG can also complete the output printing of high-fidelity 6-color images. These functions have greatly met the needs of packaging and printing companies. There are two types of hardware used for digital proofing: general-purpose inkjet printers and specially developed digital proofing output devices. China is currently using a wide range of large format printers such as Epson, HP, and Canon. It has a complete coverage of the ink color gamut of 4-color printing, but in spot color proofing, certain colors (such as fluorescent orange, green, etc.) are outside the ink gamut of ink jet printers, and current digital proofing devices based on ordinary ink jets can To restore 80% to 85% of Pantone spot colors, EPSON Stylus Pro7910/99l0/7910 Professional Edition/9910 Professional Edition 11-color large format printers have expanded the color gamut. Other specialized devices, such as Kodak Approval XP4 and Fujitsu's FinalProof, have wider color gamuts, but such systems are more costly.

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

The expansion of digital proofing to screen soft proofing is a future development direction. In the United States IPA evaluation, many manufacturers have provided a new generation of screen soft proofing programs, DALIM's Dialogue, ICS's RemoteDirector system has a very good color performance, they can be accurately displayed on Apple or EIZO color display 4-color and spot color. Can be predicted. Screen soft proofing will become a new force for color proofing.

5. Color Standards and Optimizing Color Correction Tools

After digitalization is widely implemented in the printing industry, digital proofing systems for many companies face new challenges. That is, printing companies have larger work groups, the network environment is more complex, and more people are needed. The entire system needs to support the universal ICC color flow. Work more collaboratively.

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 unification, meet domestic and foreign color standards, and better complete overseas. The production of orders, better communication with customers, sub-printing points, and out-point processing points, and achieving digital color that conforms to international standards. In order to meet the needs of users, major software companies have also introduced optimized color correction tools that can realize the color uniformity of multiple printers. EFl's colorProofXF3.0 software directly supports the correction of color standards. At the same time, color uniformity and consistency adjustment of multiple printers can be accomplished through built-in tools, which greatly satisfy the higher requirements of color printing companies. Many companies use PDF files and ICC profiles directly to complete digital proofing. Therefore, support for PDF files and lCC common standards has become a major reference point for companies to choose a digital proofing system.
6. Custom modular products

Digital proofing is constantly changing as an essential part of modern printing to meet the needs of printing companies. Each user, whether it is prepress companies, agencies, printers, or the photography industry, has different requirements for software solutions. Major software companies have introduced modular products that are more convenient for printing companies. Customization will be a trend in the future of digital proofing systems.

7. Real Dot Proofing Technology

The biggest advantage of True Dots proofing technology is that it can directly use the lbitTIFF files of the imagesetter or CTPRIP for color proofing. The entire process does not go to the net, does not re-hook the net, really retains all the output information. This kind of proofing method greatly enhances the security of digital proofing. At the same time, it also incorporates digital proofing into the printing workflow of the printing company. Because the input file of the real dot proofing technology is the lbitTIFF file after the RIP, the user does not have to worry about various RIP output traps and directly proof the results of the RIP.

8. Digital proofing using digital presses

In recent years, digital presses have entered traditional printing companies one after another. The original intention of traditional printing companies to introduce digital printing should be to supplement traditional offset printing, and to use short, fast, on-demand, personalized and special-purpose printing, but the operating rate is insufficient. Therefore, digital proofing is the main application of digital printing in traditional printing companies and has improved in quality, efficiency, and cost.

9. Digital proofing improves versatility

The development of digital proofing technology will move towards streamlining, while improving versatility and simplicity is also a hot spot for major manufacturers. The new generation PDF 1.6 version of the document has better security and complete printing information, fully able to meet the requirements of modern printing. More and more people will use PDF for digital proofing directly.
