Evaluate color measurements against your standards and tolerances, indicating pass or fail status of each measurement with the large display and colored LED 4. On-board storage holds thousands of color reference standards and measurements from press sheets, proofs and other color samples 5. 3-year warranty 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 industrys 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.
