Ghosting compensation in relief images for directional prints

摘要

It is a kind of for combining the attack of the camegraph in two source images to there is structural detail at least two principle surface to be orientated, so that the first direction of observation observed in the first image and the second image observes direction of observation immediately. The method reduce ghosting effects to include the following steps: one kind) printing test burr includes that piece and structural detail there is the surface of the first primary colours to have be orientated on the first principle orientation and the second primary colours and the second principle, primary colours are colorant of the color with predetermined amount; Step b) is measured per a piece of 1 first color observed and the second color is observed in the first direction of observation in the second visual direction; Step c) scales the first source images and makes each pixel have the structural detail of a corresponding size in camegraph with the second source images; In step d), each position camegraph structural detail is selected to test convex image from patch, the pixel calibration second source image of color difference between wherefor between the first proportional source image of the pictorial element of the sum of color difference and one first color observed and the second color for observing become minimum, e) camegraph is constituted from selected structural detail.
