Application

Colors used in printing materials are formed by C (cyan), M (magenta), Y (yellow), and K (black)., and Tthe human eye identifies the light that reflects or absorbs specific wavelengths at each position as the color of the ink. In printing, the ink made of these four colors is overprinted, and the amount of each color and the overprint conditions are used to represent various colors. So "a certain color" seen in visual observation is found to beactually a collection of multiple ink colors when it is zoomed in. The color visible to the eye can differ depending on how each person perceives it, but is greatly affected impacted by the amount, scatter, and overprint conditions of the ink, and as well as the relation relationship between ink and paper (penetration) from a quantitative point of view. Microscopic observation is useful for confirming such color differences.

The Olympus’ solution

Olympus' DSX110 digital microscope uses DSX-dedicated objective lenses, which that eliminates minimize aberration and uneven illumination at a high level. With theThe optical zoom system that realizes up to 30xx magnified observation using 16x optical zoom plus digital zoom for each of these objective lenses (1Xx, 3.6Xx, and 10Xx), DSX110 enablesenabling fine magnification adjustments and covers a wide total magnification range from 7x to 1000x. A broad area that cannot fit in one view, even at low magnification, can be imaged using the speedy live stitching function, allowing enabling you to understand the whole image of a printing material from a macro view. Iif you want to focus on a particular area, you can seamlessly move to microscopic observation to confirm in detail how ink penetrates paper, how deep the ink is, or how colors are overlaid. AlsoIn addition, using the color highlight function that enables color-display of a necessary area foran observation area of interest and makes the other area monotone, in which area or at what percentage a particular color selected in the screen is used can be grasped.
