摘要： The present invention is drawn to ink compositions and methods for ink-jet recording. The ink compositions can include a milled pigment, a surfactant, a non-aqueous co-solvent system, and at least 2 wt % resin solubilized in the ink composition. The non-aqueous solvent system comprises a main co-solvent system, where each co-solvent of this system has a surface tension less than 32 dynes/cm at 25° C. The co-solvent system also includes gamma butyrolactone and a second co-solvent system. The second co-solvent system includes one or more co-solvent(s), each having a surface tension of greater than 32 dynes/cm at 25° C. The second co-solvent system or other components can optionally act to increase the overall surface tension of the ink composition as a whole.

摘要： An ink supply system (10) is disclosed which comprises a holder (12) for receiving an inverted ink bottle (B), an ink reservoir (22) and a flow path (14, 16) down which ink can flow from the bottle (B) to the reservoir (22). Air flows along said path from the reservoir to the bottle to replace ink which has run down the flow path. The flow path terminates intermediate the upper and lower ends of the reservoir. There is an air breather (32) and an ink delivery pipe (34) for connection to the print head of a printer. The vessel (24) has a lid (26) through which the flow pipe, the ink delivery pipe and the breather pass. In one form the holder and the lid are moulded integrally with one another.
