Disclosed is a method of inkjet printing of tone and/or color images at a high efficiency production of hygienic articles. The method provides a reliable system of combining inkjet-printing operations with converting operations on a converting line producing hygienic articles having tone and/or color print images. The method utilizes at least two-inkjet print heads capable of switching between the print heads during malfunctions or maintenance procedures of one of the print heads to provide production continuity at a minimum production loss of hygienic articles.

1.

1. 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. 2. The method of claim 1, wherein the unprinted region is no greater than 10 times the pitch length. 3. The method of claim 1, wherein the unprinted region is no greater than 1 time the pitch length. 4. The method of claim 1, wherein the step of switching further comprises the steps of:a. initiating a second start signal to a converter controller for starting the second inkjet print head;b. ceasing sending a first output signal from the converter controller to the inkjet controller; andc. sending a second output signal from the converter controller to the inkjet controller. 5. The method of claim 1, wherein the step of switching further comprises the steps of:a. ceasing sending a first OK signal from the inkjet controller responding to a fail mode of the first inkjet print head;b. ceasing sending a first output signal from the converter controller to the inkjet controller; andc. starting sending a second output signal from the converter controller to the inkjet controller. 6. The method of claim 1, wherein the first velocity of the moving substrate is at least 2 meters/second, at least 3 meters/second, at least 4 meters/second, at least 5 meters/second, or at least 6 meters/second. 7. The method of claim 1, wherein the first inkjet print head or the second inkjet print head prints at least 600 images/minute. 8. The method of claim 1, wherein the substrate is a film, a non-woven material, a woven material, a foam material, or any combination thereof. 9. The method of claim 1, wherein the substrate is part of a topsheet, a secondary topsheet, an insert, a backsheet, an absorbent core, or any combination thereof. 10. The method of claim 1, wherein the hygienic articles are feminine hygiene articles, baby diapers, baby pull-on articles, baby swim articles, adult incontinence articles, and dining bibs.
