This is a dedicated app for the Epson SD-10 spectrophotometer. [Features] - The portable, compact, and easy to use SD-10 partnered with this app allows you to not only measure the color of indoor printed materials and Color Collections, but also measure outdoor signs and bulletin boards. - You can import measurement data to the app without complicated cable connections. - You can manage the colors imported to your app as reference colors, inspect them by comparing with a Color Collection, and check if the colors can be reproduced by the printer you are using. [Main Features] Color measurement: - Epson's original sensing technology realizes high-precision color measurement with a single tap in this app. Display: - Displays the measured colors in a variety of color spaces (Lab, LCh, RGB, CMYK, and LRV). - Searches and displays approximate colors from the PANTONE® Color Collection provided with this app. - Suggests colors that harmonize with the measured color. Comparison: - Compares measured colors to a Color Collection to determine the color difference. - Determines if the measured color can be reproduced by the printer you are using. Adjust: - Adjust color measurements to create a different color. Manage: - Add a variety of information (favorites, location, photos, and notes) to measured colors. - Create Color Collections (Color Palettes) to suit your needs. Linking features: - Create Color Swatch and Color Book files that can be imported into Adobe® Illustrator® and Photoshop®. [Notes] - The Epson SD-10 spectrophotometer is required to use this app. - This app connects to the SD-10 by Bluetooth®. - Emails such as "Send emails to developers" will be used for future service improvements.

Optical spectroscopy in the visible light spectrum is a commonly used tool in different fields such as health, manufacturing, art, and forensic research. OSpectrometer implements basic spectrometer functions using the built-in camera and screen without requiring external devices or programs. - Visible light spectrum is transformed and mapped to a function that generates RGB (Red Green Blue) color values - A specific light wavelength can be selected and used to illuminate a desired target (i.e., close to the screen) - The whole spectrum or a specific part of the spectrum can be selected and scanned - Front camera is used to sense the reflection from the target object - Consistent and repeatable reflection/absorption amplitude with respect to the color spectrum - The result can be saved and shared - Works offline, no need to connect to any network or internet Privacy-policy: https://software.nanorescenter.com/osprectrometer-privacy-policy Terms of use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
