Abstract

A method of communicating calibration data relates to a colour calibration article 10 having a number of coloured regions (color test patches) 20 and a calibration (pattern) element 30 for obtaining the calibration data, e.g., a 2D barcode or other image-encoded data; reference to a location for obtaining the calibration data, such as an Internet (cloud) URL; or an RFID tag device. The method comprises imaging the article with an imaging device (e.g. scanner, digital camera) to produce corresponding device data, automatically obtaining the calibration data from the calibration element and using the calibration data to obtain colour data representing the (true) colour of the coloured patch regions. The calibration pattern may be printed or photo-imaged; color patch regions may be formed from biological stain material.
