Abstract
A method and device for producing a target image having pixels (2) juxtaposed in a substrate (1) presenting thickness and producing an image presenting thickness such that each pixel (2) produces a shadowing effect on its neighboring pixels. The method includes: determining a production setpoint from the target image; and producing an image made by the device using the production setpoint. The determining operation replaces the production setpoint with an improved production setpoint that is determined by modeling the image production device using a transfer function for transforming a production setpoint into a predicted image; and determining an improved production setpoint in which the image produced by the transfer function is as close as possible to the target image, so as to reduce the consequences of the shadowing effect in the resulting image. Also included is the image produced by such a method.
