The present invention concerns an inking for a flexographic or a rotogravure press. The inking system uses a very small amount of ink coupled with an ink source made of two tanks with two different inks. Thanks to feedback given by measuring the output directly on the printed support, the system mixes the ink in the optimal proportions to ensure an optimal printing quality at any time. It can compensate any effect due to environmental changes like the humidity or the temperature. This system, coupled with a seven colours press allows for the replacement of spot colours in most cases thereby saving times and costs.

The invention discloses an inking system for a rotary printing machine, like a flexographic or rotogravure press. The inking system uses the nip area between two cylinders of the machine as the sole source for inking the printing cylinder. This results in an inking system with very little ink, thereby gaining in reaction time and ink waste.

This document discloses a system to dispense a precise and continuous amount of ink for a large printing press. The dispensing system can be judiciously combined into a more elaborate dispensing system that uses two chambers with ink having a different density to dispense ink with a precise, adjustable and stable ink density. The dispensing system can be used to compensate the drifts in quality observed in presses when the speed, or any environmentable parameters vary.

This invention discloses an ink dispensing system for a printer using the nip area between the inking cylinder and the gravure/anilox cylinder as the sole source of inking. Our solution solves the problem of reducing the amount of ink present in the inking buffer, i.e. the nip area, of such printing machines, thereby accelerating the reaction time of an ink replacement and reducing the amount of waste and the cleaning time. The idea behind the invention is to provide ink to the nip area at selected locations when needed by using a dispensing apparatus that moves along the nip area.

A rotary machine is disclosed, which includes a rotary shaft having a rotation axis, a first shaft end, and a second shaft end; a first bearing arrangement at the first shaft end; a second bearing arrangement at the second shaft end; a coupling flange mechanically connected to the first shaft end. The coupling flange is mechanically connected to the first shaft end by means of a first axial-contact coupling.

An ink station assembly is for a can decorator machine structured to decorate a plurality of cans. The ink station assembly includes a first oscillator roll and a second oscillator roll each having a longitudinal axis and being structured to oscillate back and forth along the longitudinal axis, a printing plate cylinder including a printing plate, and only one single form roll cooperating with the printing plate cylinder to apply a supply of ink to the printing plate, the single form roll cooperating with the first oscillator roll and the second oscillator roll.
