939 Color Reflection Spectrodensitometer
The Definitive Graphic Arts Color Solution
The X Rite 939 is the ultimate graphic arts Spectrodensitometer, designed to provide incomparable accuracy and usefulness in the most demanding printing, packaging, proofing and ink formulation applications.
Unparalleled Agreement
The 939 offers the industry’s premier accuracy and multi unit agreement for hand held spectrodensitometer solutions, improving upon the benchmark set by its forerunner, the X Rite 938 Spectrodensitometer. This unique capability enables only the 939 to excel in multi site or multi party agreement, giving users the ultimate assurance of matches, resulting in color consistency and confidence in product or brand color integrity. Rely on the 939 to effectively communicate color between print buyer, graphic designer, pre press and pressroom, or to exchange crucial color information with ink and paper suppliers.
Unequaled Portable Versatility
Not only does the 939 boast unrivaled inter instrument agreement, it adds the versatility of remote measurements and changeable aperture sizes. Only the 939 can quickly switch between 4mm, 8mm and 16mm apertures in the field. And with on board storage for thousands of color standards, tolerances and samples, you can make pass/fail decisions at press side or in the field with no need for an attached computer.Of course all data is time stamped and saved in memory, so ISO or vendor review reporting is a simple as connecting to any X RiteColor Master software solution and transferring your supporting data. In short, the 939 Spectrodensitometer is perhaps the most precise, intelligent QC tool for measuring and controlling color in your printing, packaging, converting or ink formulation or digital imaging operations.
Boundless Features
The advanced 939 can be used for quick evaluation of L*a*b* of an ink or substrate, Density or Dot Area measurements of a proof, and for full ink formulation when connected to X RiteColor Master software. The 939 also provides a unique spectral density and dot area function for use with special colors or HiFi printing. On board averaging gives summary information at a glance, and the graphing display can present density or spectral data graphically. Use these unique,multipurpose capabilities to minimize color mismatches and avoid costly errors by making clear decisions based on the right data, at any location in the prep or printing process.
Well Connected
X Rite can help turn your color measurement data into summarized information for use in quality reporting for ISO or other quality efforts, customer relations, vendor documentation or job history tracking. Our X RiteColor Master software solutions give you a complete picture of the measurements you make. From entry level QA Master I to advanced ink formulation with Formulation Master III, you’ll find information presented as colorful, easy to read charts, graphs and tabular data. In seconds, you’ll see how samples are measuring up to your color specifications or customer standards.
The advanced 939 Spectrodensitometer calculates dozens of color expressions including L*a*b*, Density, opacity, color strength and dozens of other useful metrics. Each one is presented using the large graphical display and intuitive 939 keypad.
