The production of printed materials often requires accurate colour matching, for example when a brand has trademarked a colour, eg Cadbury's purple and Tiffany's turquoise blue. But even in the absence of trademarks, some companies take great pains to ensure that their logos are consistently reproduced in just the right shade.
And more generally, why wouldn't you want accurate colour reproduction?
The self-calibrating Epson SD-10 spectrophotometer was designed to allow anyone to easily measure and quantify colours without specialised knowledge traditionally needed, Epson officials said.
The SD-10 uses nine light sources, and readings are said to be unaffected by surface variations or the external environment.
It can be connected to an Android or iOS device via Bluetooth, and used with the Epson Spectrometer app, which displays measurements in formats including LAB, CYMK, LCH and RGB. The app can be used to compare approximate colours and numerical values, and to compare the colour differences between two measured colours and display the difference numerically.
The app also identifies similar colours to measured colours (including similar Pantone colours) and complementary colours, and provides sample colour schemes.
Wired and wireless connections to PCs are also supported, and the SD-10 has a high-capacity lithium ion battery.
Combining the SD-10 with Epson's Epson Edge Print and Epson Edge Print Pro software delivers the exact colour required with any Epson large-format inkjet printer.
