Abstract
A scanning densitometer is disclosed for obtaining color density measurements from colored samples, such as color bars and the like. The scanning densitometer includes a densitometer head (100) and a densitometer head transport system (101) having transport bars (102, 103). A sample sheet is positioned under the transport bars (102, 103) and the self-propelled head (100) moves over the sheet along the bars (102, 103) toward an end limit stop (105). During a return movement from the end limit stop (105) to a docking end housing (110), color measurement data is obtained. Upon docking at the docking end housing (110), an optical communications interface is provided so that data from the densitometer head (100) can be transmitted to a host computer.
