Color management

(Color Management)
In 2001, color management technology advanced by leaps and bounds, and its use was simpler and more users accepted it. The following content briefly summarizes various advancements in software, test instruments, and processes.

Available software
Apple ColorSync: ColorSync is a Mac system-level color management software based on the open standards developed by the International Color Consortium (ICC). John Zimmerer, Apple ColorSync product manager, said: "ColorSync is strictly compliant with Mac OS X to ensure that every pixel processed by Quartz can get color management from start to finish, from capture to display To print, the same architecture is used by both general users and professional users, the only difference being that the difference in color accuracy requirements will determine the quality of the profile.

Monaco Systems: At Print 01, Monaco Systems announced the upgrade of their MonacoProof and Monaco Profiler color management systems to version 3.5. Both versions have improved color quality and are able to support LCD displays. MonacoProof is used in handheld devices that work with profiles, printing equipment, development and scanner profiles, and MonacoProfiler works with an automated spectrophotometer. The new version of MonacoProfiler has some new features: use Macbeth ColorChecker DC to generate profiles for digital cameras, use Don Hutcheson's new HutchColor color code to generate scanner profiles, and also to use PANTONE Hexachrome's six-color separations, using standard IT8. 7/3 Extended Data Generation Printer Profiles.

Heidelberg: Heidelberg has introduced version 4.0 of its three color management software, Scanopen (for scanners and digital cameras), Viewopen (for displays), and Printopen (for output devices). The new version of Printopen enables conversions from CMYK to CMYK profiles, editable profiles, and high-quality profiles. The processing of shadow details in Scanopen 4.0 has been improved to support the G4 Apple Computer. Viewopen 4.0 supports Sequel's Chroma IV monitor colorimeter. All three software can be run on Macintosh system9, OS X, and Windows operating systems.

Pictographics: Probably Pictographics International is best known for its ColorSynergy profile software, and recently they introduced version 3.0 of the icorrect Professional Image Enhancement Plug-in for Adobe Photoshop. iCorrect is designed to enhance the color of digital photos. Earlier this year, the company also introduced inCamera, a professional software that uses Macbeth ColorChecker and ColorChecker DC to generate digital camera profiles.

Praxisoft introduced version 3.5 of its profile software, Compass ProfilePro 3.2. Compass ProfilePro 3.2 is based on MonacoPROFILER 3.5.

The company's spot color management software, VectorPro, now supports up to eight colors of HIFI color. VectorPro is software that allows copying of vector colors such as PANTONE analog colors, Focoltone, and custom spot colors.

Praxisoft's server-based color management feature file software, ICC AutoFlow, supports HiFi color in 2002.

GretagMacbeth announced their ProfileMaker 4.0 program at Print01, where the upgraded software can describe scanners, digital cameras, monitors and printers. Version 4.0 redesigned the interface to support up to eight colors of HiFi color, including Pantone Hexachrome.

The company also introduced iCColor, a new x/y-axis scanning spectrophotometer that scans a color patch with 288 patches in two to three minutes. ICColor scans reflection and transmission color marks for use in the printing industry in prepress and image processing applications.

At the Seybold Symposium in Boston, GretagMacbeth launched the Eye-One (One-Pass) Color Management System, which is sold to creative workers including designers, art directors, and digital photographers. The Eye-One uses a hand-held reflectance, emission spectrophotometer, which can be used to describe printers, displays, and LCD displays. Eye-One works with Eye-One Match feature software and Eye-One Share Palette software to create and share colors in various applications.

X-Rite introduced the DTP32 QuickCal, an inexpensive handheld scanning densitometer designed to calibrate color output devices such as copiers, large format printers, and more. In addition, the company also announced that it will upgrade its 530 spectrophotometer series of products, the new product will have a color matching function, able to store the received color information. The new model also takes full advantage of X-Rite's proprietary ColorMail technology to enable the sharing of rigorous color data between desktop PCs and test instruments. X-Rite also announced that their Spectrofiler 2 software for automated tracking of spectrophotometers can read color patches as small as 1/16×3/16 inch (1.6×5 mm). Typical color management test images and color patches (6 x 6 mm) require a significant amount of time and cost to run the press in order to produce an ICC profile. In contrast, Spectrofiler2 software can get color management feedback from any color matching machine.

Desktop color proofing

With the continuous advancement of ink-jet printers and toner printer technologies, many printing companies are faced with explaining to customers why the effect of offset printing sheets does not look like proofs. One of the current trends in desktop proofing is the use of profiles based on ICC color management to simulate printing conditions such as: SWOP, SNAP, GRACol, and other user-specific printing parameters. HP introduced the HP Designjet 10ps/20ps/50ps series of inkjet proofers, while Epson's 3000, 5000, 7000, and 9000 proofers also use ICC color management to perform RIP processes. Xerox's Tektronix 7700 chose the Phasermatch characterization application software to implement printer color management to achieve user-specific or pre-set parameters. Other companies also choose this ICC-based proofer to easily match the printing conditions, thereby avoiding customers explaining why the final printed product is not proofed.

Remote proofing
RealTimeProof is a set of web-based solutions for remote soft proofing or hard proofing. Service providers and customers can work together to achieve on-the-spot observation of proofs through the Internet, similar to online interactive chat rooms. Users can simply create a free, downloadable plug-in on their browser on a Mac or PC, allowing them to proof-read their files anywhere at any time.

At the Seybold Symposium in Boston, RealTimeProof announced a cooperation agreement with Imation, which will provide a visual proofing system for Imation Virtual Matchprint. At PRINT01, the company announced that Heidelberg will supply HDPROOF, which uses color management and DeltaRIP technology from Heidelberg.

At PRINT01, Global Graphics (formerly known as Harlequin) launched the Remote Director complete remote proofing product based on Lotsadots observation technology.

Peder Nelson, president of Color Management Consulting at Chromaticity, said: “The printing and publishing industry has come to realize that color management is a process, not a product. It is an open technology that can be integrated into a unique The process goes to provide users with multiple functions.Color management technology is currently used to improve the process, improve productivity, reduce the time and cost of waste.A color management workflow can accept a variety of technologies, such as: digital Proofing, remote proofing, CTP, digital resource management, soft proofing, etc. These technologies can drastically reduce the time and costs associated with print production."

The future of color management There will be no major breakthrough in color management in the coming years. However, it will become a mature technology, and it is also a hot topic of concern. We will see the rapid progress of the corresponding software (better characterization quality, use a simpler interface). This can be seen in the software that has emerged in recent years, such as: GretagMacbeth ProileMaker Pro4.0, ColorBlind 4.0, MonacoPROFILE3.5.

Another trend we will see is cheap, easy to use, fast color measurement instruments. More users this year are interested in a monitor (emission) colorimeter capable of reading LCD displays and CTR (Cathode Ray Tube). Instruments that can read LCD screens are GretagMacbeth Spectrolino and Eye-one, SpectroStar Spectrocam. An example of a fast automated instrument is GretagMacbeth's iColor x/y-axis scanning spectrophotometer.

Today, color management has been well understood by people. It is a mature technology used in different applications, such as: scanning, digital photography, digital proofing, and output for offset, flexo, gravure, and other processes.
