In one example, a web press includes a web press station () and a convertible buffer () near the web press station, the convertible buffer being configured to convert to a platform () for accessing the web press station. A method for performing web press maintenance is also disclosed.

Convertible buffers for web presses

In one example, a web press includes a web press station and a convertible buffer near the web press station, the convertible buffer being configured to convert to a platform for accessing the web press station. A method for performing web press maintenance is also disclosed.

A printing device () has a first print engine (), a second print engine (), and a buffer device () disposed between the first () and second print engines (). The buffer () is configured to store a variable amount of web substrate () received from the first print engine () and feed the substrate () to the second print engine ().

In one embodiment, a method for controlling an ink supply system includes operating a pump of the ink supply system in a forward direction to supply ink from an ink reservoir to an ink tank, and subsequent to operating the pump in the forward direction, reversing the pump and operating the pump in a reverse direction to prevent or reduce formation of clogs within the ink supply system.

Self-cleaning ink supply systems

A method and apparatus for printing fluid on a substrate is provided. The method includes providing drops of the fluid on the substrate and spreading the drops of fluid to increase the surface area covered by those drops. The apparatus includes a printer having a print head for printing drops of fluid on the substrate and a spreader for spreading the fluid drops on the substrate.

Method and apparatus for printing fluid on a substrate

The present invention provides a digital offset printing method for producing a composite image on a substrate wherein the image is made up of a first plurality number of component images, each being formed from a different ink. The method comprises providing a first component image on a first surface, transferring the first component image from the first surface to an intermediate transfer module, repeating said provided and transferring steps for further component images until a second plurality number, less than the first plurality number, of component images has been accumulated on the intermediate transfer module, and transferring the accumulated component images from the intermediate transfer module to the substrate. The step of transferring the accumulated images from the intermediate transfer module to the substrate comprises applying a plurality of inks, which correspond to the second plurality number of accumulated component images, to the substrate, and repeating said steps until all of the first plurality number of component images have been transferred to the substrate.
