Abstract:
1. A method for simulating the function of an image conversion device wherein said image conversion device is an inkjet printer and wherein said method comprises steps of a. reading input image data; b. recording the physical transformations of the base elements in at least one process step; c. emulating a predetermined number of processes; d. recording the final states of the base elements; e. collecting the base elements states following the last simulation step; f. transforming said collection into the simulation file; and, g. printing or displaying said simulation file; said method further comprises the steps of: h. reading the original image data; i. processing said original image data according to the data interface of the print heads and the printing flow; j. transferring print pass data to a data structure representing the print heads array; k. simulating the static structure of the print heads array; l. simulating the relative motion between said heads array and the substrate; along the slow axis with respect to the start position of the coming print pass; m. simulating the relative scanning motion between said heads array and the substrate along the fast axis; n. recording the XYZ position and velocity of each nozzle in said print heads array each time drops are ejected during the motion along the fast axis; o. calculating said drops trajectory to the substrate; p. selecting a predetermined ink-substrate interaction model; q. calculating parameters selected from a group consisting of position coordinates, shape, size and colour of said ink dot on said substrate at time that ink is fixed on said substrate; r. repeating steps j through q until the whole image is reproduced on said substrate; s. generating an output image file from the final appearance of said ink on said substrate thereby making up a complete image from individual dots; t. storing said output file on disk or other media; and, u. displaying or printing said file.
