摘要： Present invention relates to an ink jet printing method implemented in a computer system comprising the steps of providing an ensemble of dots to be printed, running through the ensemble of the dots to be printed, deleting, for each dot of the ensemble of the dots, all the neighbouring dots whose distance is less than at least one predetermined value (Dmin) and keep non deleted dots as remaining dots, assigning the remaining dots to a certain layer corresponding to the run, removing the remaining dots from the ensemble of the dots, and starting again at the running step for a further run if there are further dots in the ensemble of the dots or stop so as to have all dots assigned to printing layers corresponding to the number of runs done.

摘要： Present invention discloses an image processing method suitable for a printer unit, comprising an error diffusion halftoning process (230) arranged for quantizing and diffusing each pixel of an image including a set of subtractive primary colours (C, M', Y'), in an image including a quantized printer image including a set of ink drops (Dc, DM, Dγ, Dc, Dm) of respective ink channels to be printed. The method comprises the step of determining (220), for each pixel, an input variable value (S) representing a measure of solvent quantity that should be ejected by the printer unit for each pixel, the input variable value being computed on the basis of the value of a corresponding pixel of the image including the set of subtractive primary colours (C, M', Y'), and of inputting (225) the determined input variable value (S) in the error diffusion halftoning process (230) together with the values of the corresponding pixel. The invention further relates to the apparatus embodying the method.
