Abstract:
A method of inkjet printing in a high efficiency production of hygienic articles, having a print image, on a converting line including at least two inkjet print heads, the method comprising the steps of:(a) providing a substrate moving in a web direction at a first velocity; (b) printing on the substrate a first plurality of images by a first inkjet print head disposed in proximity to the substrate, the images being separated from each other in the web direction at a pitch interval; (c) switching from the first inkjet print head to a second inlet print head while the substrate continues its movement; and (d) printing on the substrate a second plurality of images by a second inkjet print head disposed in proximity to the substrate, the images being separated from each other at the pitch interval, wherein the first plurality of images is separated from the second plurality of images by an unprinted region in the web direction, wherein the unprinted region is no greater than 50 times the pitch interval.
