Abstract
A sub-controller (), controller (), fluid supply system and apparatus for printing and a method for printing. Provided is a processor controlled sub-controller () for controlling the fluid pressure in one or more droplet ejection heads (); wherein said controller () is configured to receive a droplet ejection head movement profile for each of said one or more droplet ejection heads (), determine a respective induced fluid pressure profile at one or more predetermined locations for each of said one or more droplet ejection heads () using the respective droplet ejection head movement profile; and generate respective pressure correction data for each of said one or more droplet ejection heads based on the respective induced fluid pressure profile and a predetermined pressure window to be maintained at said one or more droplet ejection heads (). Also provided is a method of printing using one or more droplet ejection heads () fluidically connected to a fluid supply system wherein said method comprises the steps of receiving droplet ejection head movement profile(s); determining a respective induced fluid pressure profile at one or more predetermined locations for each of said one or more droplet ejection heads using the respective droplet ejection head movement profile(s); generating respective pressure correction file(s) at said one or more predetermined locations based on said induced fluid pressure profile(s) and said predetermined pressure window.
