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.

1. A liquid supply assembly for a printing system, the liquid supply assembly comprising: a reusable hollow body having a first end and a first flange that laterally extends outward from the first end and extends around the first end;a disposable cup insert that defines a liquid reservoir for holding ink, the disposable cup insert having a closed base and an opposite open outlet that is positioned at the first end of the reusable hollow body, the disposable cup insert also including a second flange that laterally extends outward from the open outlet and encircles the open outlet;a doctor ring shaped to be positioned outside at least a portion of the disposable cup insert at the first end of the reusable hollow body and outside at least a portion of the first end of the reusable hollow body in order to define a conduit through which the ink flows from the liquid reservoir of the disposable cup insert to a cliché plate for applying the ink to one or more objects via the cliché plate; anda seal positioned between two or more of the reusable hollow body, the disposable cup insert, or the doctor ring,wherein the first flange of the reusable hollow body forms a seat in which the second flange of the disposable cup insert sits to secure the disposable cup insert to the reusable hollow body. 2. The liquid supply assembly of claim 1, wherein the seal prevents leakage of the ink in the liquid reservoir of the disposable cup insert outside of the doctor ring. 3. The liquid supply assembly of claim 1, wherein the doctor ring is shaped to be positioned outside of the at least a portion of the disposable cup insert and the at least a portion of the first end of the reusable hollow body such that the least a portion of the disposable cup insert is disposed between the doctor ring and the at least a portion of the reusable hollow body. 4. The liquid supply assembly of claim 1, wherein the disposable cup insert is flexible to allow the disposable cup insert to expand due to pressure increases within the liquid reservoir of the disposable cup insert. 5. The liquid supply assembly of claim 1, wherein the doctor blade is shaped to secure the disposable cup insert between the doctor blade and the first flange of the reusable hollow body in the seat formed by the first flange of the reusable hollow body. 6. The liquid supply assembly of claim 1, wherein the reusable hollow body is a single piece body having an exterior wall oriented in a first direction and the first flange outwardly protruding from the exterior wall in a second direction that is perpendicular to the first direction, and wherein the disposable cup insert is shaped to engage both the exterior wall and the first outwardly protruding flange of the reusable hollow body when the doctor blade is disposed outside of the disposable cup insert and the reusable hollow body at the first end of the reusable hollow body. 7. The liquid supply assembly of claim 6, wherein the exterior wall of the reusable hollow body transitions into the first flange to define the seat of the reusable hollow body at the first end of the reusable hollow body. 8. The liquid supply assembly of claim 1, wherein the reusable hollow body is a single piece body. 9. The liquid supply assembly of claim 1, wherein the disposable cup insert has the closed base such that the ink disposed in the disposable cup insert cannot pass through the closed base. 10. The liquid supply assembly of claim 1, wherein the laterally outwardly protruding flange of the disposable cup insert encircles the open outlet of the disposable cup insert. 11. The liquid supply assembly of claim 1, wherein the disposable cup insert engages both of opposite interior and exterior sides of at least a portion of the reusable hollow body at the first end. 12. A liquid supply assembly for a printing system, the liquid supply assembly comprising: a reusable hollow body having a first end with an exterior wall that transitions into a first outwardly protruding flange to define a seat at the first end, the first exterior wall oriented in a first direction, the outwardly protruding flange oriented in a second direction that is perpendicular to the first direction;a disposable cup insert that defines a liquid reservoir for holding ink, the disposable cup insert having a closed base and an opposite open outlet that is positioned at the first end of the reusable hollow body, the disposable cup insert having a laterally outwardly protruding flange encircling the open outlet and shaped to sit within the seat of the reusable hollow body; anda doctor ring shaped to secure the disposable cup insert between the doctor ring and the first exterior wall of the reusable hollow body at the first end, the doctor ring defining a conduit through which the ink flows from the liquid reservoir of the disposable cup insert to a cliché plate for applying the ink to one or more objects via the cliché plate. 13. The liquid supply assembly of claim 12, further comprising a seal positioned between two or more of the reusable hollow body, the disposable cup insert, or the doctor ring. 14. The liquid supply assembly of claim 13, wherein the seal prevents leakage of the ink in the liquid reservoir of the disposable cup insert outside of the doctor ring. 15. The liquid supply assembly of claim 12, wherein the doctor ring is shaped to be positioned outside of at least a portion of the disposable cup insert and at least a portion of the first end of the reusable hollow body such that the least a portion of the disposable cup insert is disposed between the doctor ring and the at least a portion of the reusable hollow body. 16. The liquid supply assembly of claim 12, wherein the disposable cup insert is flexible to allow the disposable cup insert to expand due to pressure increases within the liquid reservoir of the disposable cup insert due to evaporation of a liquid mixture disposed in the liquid reservoir. 17. The liquid supply assembly of claim 12, wherein the doctor blade is shaped to secure the disposable cup insert between the doctor blade and the first outwardly protruding flange of the reusable hollow body. 18. The liquid supply assembly of claim 12, wherein the laterally outwardly protruding flange of the disposable cup insert and the first outwardly protruding flange of the reusable hollow body have complementary shapes at the first end of the reusable hollow body such that the laterally outwardly protruding flange of the disposable cup insert is disposed alongside and engaged with the seat formed by the first outwardly protruding flange. 19. The liquid supply assembly of claim 18, wherein the laterally outwardly protruding flange of the disposable cup insert encircles the open outlet of the disposable cup insert. 20. The liquid supply assembly of claim 12, wherein the disposable cup insert has the closed base such that the ink disposed in the disposable cup insert cannot pass through the closed base. 21. The liquid supply assembly of claim 12, wherein the disposable cup insert engages both of opposite interior and exterior sides of at least a portion of the reusable hollow body at the first end.
