The SD-10 is an ultra-compact high-precision spectrophotometer. Small in size but big in features, it is designed to be your constant print companion. It lets you determine the exact color of a test item and compare it with another or with a known standard such as Pantone. You can scan a series of items and compare the colors as a group. Data can be stored for subsequent recall, analysis and export. Small enough to fit in a jacket pocket, it has a high capacity lithium ion battery so you can take it wherever you need to be; out with a customer or a supplier, over with a designer or down on the production floor. Most importantly the readings you take are accurate and consistent. Accessory Type: Spectrophotometer; For Use With: Epson SureColor S-Series Printers.
