Some embodiments of the invention relate to an article of manufacturing for printing on a foamed beverage comprising: an ink-jet cartridge; and a sugar-poor and unfermented-wort-based ink formulation disposed within the ink jet cartridge. The unfermented wort is the primary colorant of the ink formulation. In embodiments of the invention, (i) a ratio between the EBC number of the ink formulation and the 25° C. viscosity thereof is at least 400 (centipoise).sup.−1; (ii) the ink formulation is characterized by at least a EBC number of at least 1800 colorant units; (iii) the ink formulation comprises at least 10% wt/wt carbohydrates; (iv) the ink formulation is sugar-poor such that a ratio between a wt/wt% concentration of soluble sugars and a wt/wt concentration of carbohydrates in the ink formulation is at most 0.2 (e.g. ≤0.1 or ≤0.05); and (v) at least 60% of particles of the ink formulation are sub-400 nanometer particles.

The invention relates to a light-emitting element dispersing agent; a light-emitting element ink comprising the same; and a method for producing a display device. This method for producing a display device may comprise spraying an ink including a solvent, light emitting elements, and a light emitting element dispersant onto a target substrate provided with a first electrode and a second electrode, applying a voltage to the first electrode and the second electrode to generate an electric field on the target substrate, irradiating the ink sprayed on the target substrate with light to form a dispersant fragment in which the light emitting element dispersant is decomposed, and removing the solvent and the dispersant fragment of the ink.
