Hexachrome

From Wikipedia, the free encyclopedia

Hexachrome was a six-color printing process designed by Pantone Inc. In addition to custom CMYK inks, Hexachrome added orange and green inks to expand the color gamut, for better color reproduction. It was therefore also known as a CMYKOG process. Hexachrome was discontinued by Pantone in 2008 when Adobe Systems stopped supporting their HexWare plugin software. While the details of Hexachrome were not secret, use of Hexachrome was limited by trademark and patent to those obtaining a license from Pantone. The inventor of Hexachrome was Richard Herbert, who is also the president of Pantone Inc.[1]

Richard Herbert

Richard Herbert is the COO and President of Pantone Inc.; these titles were handed down by his father, Lawrence Herbert. After realizing that graphics and printing would soon be completely taken over by computers,[1] Richard obtained degrees in Computer Engineering and business from Hofstra University, hoping to improve the digital application and printing of color.[2] He was responsible for many achievements of Pantone Inc.; such as digitizing the Pantone Matching System and incorporating the print and display data from the previously used CMYK model. Herbert continued to keep Pantone Inc. at a high standing in the field of color communications, as its matching system was used internationally.[2]

Software

In order to use the Hexachrome process in a digital printing process, Pantone produced a plugin for Adobe Photoshop that allowed the designer to work in an RGB color space more typical of computer work.[3] The plug in was called HexWare, which contained a set of Adobe plug-ins used by printers and designers who used the Hexachrome system.[3] Older versions of QuarkXPress and Adobe InDesign also came with the Hexachrome system already installed and enabled.[3]

Purpose

The main purpose of Hexachrome was to create a printing ink system that could depict brighter and clearer picture by being able to produce more accurate colors.[4] Using this system instead of the CMYK ink system prints also allows for more accurate skin tones and pastels.[5] The Hexachrome system, for the first time, lets users print the images from computer screens that were not able to be accurately duplicated before.[5] As well as producing overall better quality than previous systems, Hexachrome also increased efficiency as it produces many more spot colors.[4] Having more spot colors increases efficiency because it allows for the press to use one ink set for all jobs, rather than one specified ink set for each job. Keeping a printer configured for Hexachrome also eliminates the number of washes required on the printer; therefore saving times and simplifying printing production.[4]

Users

Some software companies that employed the Hexachrome system were Aldus (now Adobe), Adobe Photoshop, and QuarkXPress; as well as the printer manufacturers HP, Epson, and Xerox.[1]
