HP Didi Newsprint Color Digital Proofing Solution

The timeliness of the news determines that the production time of newspapers before printing is usually very short. Traditional platemaking does not have the time for mechanical proofing, but the printing speed is fast. The dot gain during the printing process is unpredictable, and the effect of printing image and arrangement design is often inconsistent. The printed newspapers did not reach the result of editorial expectations.

In view of this status quo of newspaper printing, with reference to the success of offset printing quality management, Hewlett-Packard and Rainbow Dijet launched a digital proofing system using newsprint as the proofing paper—the HP Dijon newsprint color digital proofing program.

The newspaper digital proofing program uses the same paper-newsprint printing as newsprint to print digital printing. It can simulate the dot gain in the printing process, simulate the final print vividly, and provide the basis for color reproduction for the newspaper in the printing process. The expected effect of plate making. The Hewlett-Packard and Rainbow DiJie newsprint color digital proofing solution solves the problems caused by the printing press before printing without color newsprint. The editing department of newspapers can first review the newsprint proof and then deliver the printing.

The HP Dijon newsprint color digital proofing program consists of three parts:

1. HP 1000 Series Color Inkjet Printers;
2. Support color management system CMS applications, such as Best's ColorProof software;
3. Rainbow Dijet Color Management Data Integration Module CMM.

Its components have their own advantages:

1. HP 1050 Printer * A new generation of printheads using JetExpress technology, with 512 nozzles per inch, prints a four-page newsprint newsprint for approximately 5 minutes.
* Built-in hp JetDirect10/100 base-TX EIO network card, network integration is quick and easy.
* Printing ink is especially suitable for newspaper newsprint printing

2. Applications that support the color management system CMS 1) BEST's Color Proof, which has the following features:

* Friendly operation interface * Print results can be previewed before printing * Print color correction through ICC files, high color correction accuracy * Built in a variety of ICC files to adapt to different proofing conditions * Multiple channels can be set up to suit different requirements Proofing

2) Jin Hao's Express RIP, which features:

* Support Postscript Language Level 3
* Support PDF, TIFF, PS, EPS and other formats of file output and processing * Realize the dream of a set of RIP can drive up to 4 output devices

3) Color Tuner of CGS

* Supports all Windows-enabled printers * Strong color correction

4) Black Magic

* Supports RIP output, printable AM ​​outlets * High color correction accuracy

5) Founder digital proofing can be used in addition to the other party's system software to do digital proofing, other software can also be used.

6) Lab Proof is specifically designed for use with digital processes.

3. Rainbow Dijet Color Management Data Integration Module CMM

The color management technology based on ICC is adopted as the core of the color management system, and the ICC Profile is a color characteristic description file generated based on the ICC standard. Through ICC color management technology, the exact color characteristics and compensation methods of the printer and the color printer are determined. Based on this, accurate color conversion is performed to achieve the best color simulation effect. Ensure that the gamut space of the color printer in the workflow can be accurately converted to the printed gamut space.

Rainbow Dijon color management module CMM is the use of professional digital proofing software combined with other color management software, fine-tuned color space conversion data integration. The data integration includes an ICC profile that accurately reflects the suitability of the printer and the printability of the color printer, and also includes a combination of data that edits and corrects the ICC file based on the deviation of the physical measurement value and the deviation from the human visual observation. These data centered on domestic commonly used printing materials and processes, including offset printing, gravure printing, newspaper printing, etc., and conducted a large number of in-depth color space model experiments to simulate the printing and proofing results under simulated production conditions. The data was measured accurately. And comprehensive.
