Title: Measuring Colour Densities for Printing
IPC: G01J3/51
Filed: 1980-01-17
Abstract: A system for controlling the inking unit of a printing press uses the color densities of a color teststrip 2, printed on paper along with other material, making use of a measuring head 1 with color filters 20-23. The head is moved smoothly along strip 2. The jumps in density intensity on moving from one test target, forming part of the strip, to the next is used for detecting the target boundaries. There is a filter wheel 18 with the respective colors of the strip continuously turning in the path of light reflected from strip 2. Photosensor 24 feeds an electronic switch 26 synchronized so that density signals corresponding to the strip colors are stored in respective memories 30-33. The boundaries are detected using double- differentiation of the respective color density curves. False indication of boundaries is prevented by an indication only being given when the first derivative exceeds a threshold. <IMAGE>
