<p>An apparatus for automatically collecting a plurality of color readings from a corresponding plurality of color patches (16) applied to a sheet (14), and for transmitting the plurality of color readings to a host computer includes: a color sensor (20) mounted on a carriage motorized for reciprocation along a predetermined carriage path; a feed (17) for feeding the sheet along a predefined feed path, where an exposed portion of the feed path runs in a direction substantially perpendicular to at least a sensing portion of the carriage path, and where the exposed portion of the feed path is substantially adjacent to the sensing portion of the carriage path to allow the color sensor to sense colors applied to the sheet fed to the exposed portion of the feed path, along the entire sensing portion of the carriage path; a carriage control (56) for controlling the position of the color sensor along the sensing portion of the carriage path; a feed control (58) for controlling the position of the sheet along the feed path; and interface (60, 62) for providing a data link (63) to a host computer; and a microcontroller (66) operatively coupled to the carriage control, the feed control, the color sensor and the interface, and including circuitry and/or programming adapted to operate the carriage control and feed control so that the color sensor is separately exposed to each of the color patches applied to the sheet, and for each separate exposure of the color sensor to one of the color patches, is further adapted to activate the color sensor, obtain a color reading from the color sensor, and transmit data corresponding to the color reading over the data link via the interface.</p> |
