Patent number: 8955939Abstract: An ink jet printing method includes providing an ensemble of dots to be printed. A current run is made of through the ensemble of dots to be printed, which includes, for each of dot of the ensemble of dots, deleting all neighboring dots from the current run having a distance less than at least one predetermined value and keeping non-deleted dots as remaining dots in the current run. The remaining dots are assigned to a certain layer corresponding to the current run. The remaining dots of the current run are then removed from the ensemble of dots. The foregoing steps are repeated until there are no further dots in the ensemble of dots.Type: GrantFiled: December 30, 2010Date of Patent: February 17, 2015Assignee: SICPA Holding SAInventors: Serge Cattarinussi, Ana Dimitrijevic, Yves-Julien Regamey

Patent number: 8824013Abstract: An image processing method suitable for a printer unit, includes an error diffusion halftoning process arranged for quantizing and diffusing each pixel of an image including a set of subtractive primary colors (C?, M?, Y?), in an image including a quantized printer image including a set of ink drops (DC, DM, DY, Dc, Dm) of respective ink channels to be printed. The method comprises the step of determining, 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 colors (C?, M?, Y?), and of inputting the determined input variable value (S) in the error diffusion halftoning process together with the values of the corresponding pixel. The invention further relates to the apparatus embodying the method.Type: GrantFiled: September 3, 2007Date of Patent: September 2, 2014Assignee: Sicpa Holding SAInventors: Rosa Maria Figueras I Ventura, Ana Dimitrijevic, Kevin Fine, Serge Catarinussi

Patent number: 7988251Abstract: A method of printing from a printhead includes virtually dividing a nozzle array of the printhead into first and second nozzle sections. N print masks associated with the first and second nozzle sections govern the deposition of ink drops on a print medium. The N print masks are associated with one swath and are defined as a mask grid. The mask grid is arranged as a series of vertically extending adjacent mask columns and a series of horizontally extending mask rows. The vertically extending mask columns comprise enabling mask columns comprising first mask elements and disabling mask columns consisting essentially of second mask elements. The N print masks are associated with the first and second nozzle sections for printing an input image. Each print mask is defined as a mask grid arranged in an N series of vertically extending adjacent mask columns and a series of Z horizontally extending mask rows.Type: GrantFiled: July 3, 2006Date of Patent: August 2, 2011Assignee: Telecom Italia, S.p.A.Inventors: Ana Dimitrijevic, Serge Cattarinussi, Taha Baroud
