Abstract
A method for correction of a trapezoidal distortion of images in image processing for improved medium-image registration and also for controlling a printing device by performing the method for correction of a trapezoidal distortion of images in image processing for improved medium-image registration. Also included is a printing device comprising a controller for performing the present methods.
Claims11
A method for correction of a trapezoidal distortion of images in image processing for improved medium-image registration, comprising the steps of:
- A) determining the trapezoidal distortion of an image to be registered,
- B) calculating a pattern of linear arrays of image pixels to be omitted or to be added to correct for the trapezoidal distortion determined under step A), which pattern comprises an amount and a positioning of the linear-arrays, and
- C) registering the image onto a medium , wherein the multiple linear image pixel arrays calculated under step B) are omitted or added,
- wherein pixels reproduced by means of a half-toning technique are used to register the image during steps A)-C).

- C) registering the image onto a medium, wherein the multiple linear image pixel arrays calculated under step B) are omitted or added,
- wherein the linear pixel arrays to be omitted or to be added have a length up to the width of the image to be registered during step C), and wherein the lengths of the linear image pixel arrays are mutually substantially different and oriented substantially randomly.
