Abstract:
1. A liquid supply assembly for use with a printing system of a type in which a liquid is deposited from the liquid supply assembly in a receiving region on a plate and any excess of the liquid in the receiving region is scraped from the plate by the liquid supply assembly, the liquid supply assembly comprising: a reusable cup including a reusable liquid reservoir; a disposable cup insert including a temporary liquid reservoir operable to hold the liquid within the reusable liquid reservoir wherein the disposable cup insert includes a hollow reservoir body having an open outlet and a closed base defining the temporary liquid reservoir and wherein the closed base has a flexible material composition to facilitate an expansion of the temporary liquid reservoir in response to an increase in gas pressure exerted by the liquid on the temporary liquid reservoir; and a scraping element including a conduit operable to be in liquid communication with the temporary liquid reservoir and the plate to facilitate a flow of the liquid held by the temporary liquid reservoir through the conduit to the plate, wherein the open outlet includes a flange operable to be physically aligned with the scraping element to thereby establish the liquid communication between the temporary liquid reservoir and the conduit, and wherein the flange includes a seat operable to support a seal ring between the flange and the scraping element.
