Method for printing substrate using anilox roll, ilox roll for printing method and printing apparatus

Abstract

The invention relates to an anilox roll for a printing apparatus. The anilox roll comprises a cylinder having a surface. The surface comprises a fluid distribution structure for receiving, distributing and transferring a fluid such as an ink. The fluid distribution structure comprises a channel formed in the surface having channel walls. This channel is arranged for distributing the fluid over the fluid distribution structure. The channel comprises channel parts, wherein the courses of connected channel parts are at an angle with respect to each other for preventing a linear distribution of the fluids to be received in a course direction of the channel, allowing a meandering distribution of the fluid to be received in the channel. Side walls of the channel are arranged for allowing a meandering flow of the fluid throughout the fluid distribution surface.

Description

technical field [0001] The invention relates to an anilox roller. The present invention also relates to a substrate printing method using an anilox roll. The invention further relates to a printing apparatus comprising an anilox roll. The invention also relates to the use and formation of anilox rolls. Background technique [0002] Anilox rolls have been used in the flexographic printing process in the printing industry. This printing method is generally used for printing different substrates such as paper, labels, tapes, (plastic) bags and boxes. Anilox rolls can also be used for printing methods other than flexographic printing methods, as well as offset printing and gravure printing. Anilox rolls used in these other methods are used to deliver ink precisely and consistently. [0003] Anilox rolls consist of a generally rigid cylinder with a steel or aluminum core. A thin ceramic layer is placed on top of the core. Small ink cells (hereinafter collectively referred ...
