Abstract: 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. To this end, the liquid supply assembly employs a reusable cup, a disposable cup insert and a scraping element. As assembled, the reusable cup includes a reusable liquid reservoir, the disposable cup insert includes a temporary liquid reservoir holding the liquid within the reusable liquid reservoir, and the scraping element includes a conduit facilitating a flow of the liquid held by the temporary liquid reservoir through the conduit to the plate.
