AUTOMATIC INK CARTRIDGE DISPENSER

摘要

A method of dispensing ink that includes installing a cartridge having an ink-filled chamber into the dispenser of a web fed or a sheet fed offset printing press, with the chamber being defined by a tubular body, a fitment at a dispensing end having an outlet port closed by a valve, and a plunger slidably disposed in the open end of the tubular body opposite the dispensing end. The method includes weighing the cartridge in situ with a weighing device positioned within the ink dispenser to determine an initial weight of the cartridge prior to dispensing ink, dispensing ink from the cartridge throughout the print job, and weighing the cartridge in situ to determine an ending weight of the cartridge prior to removal from the ink dispenser. The ending weight is then subtracted from the initial weight to determine the weight of the ink dispensed during the print job.

1. A method of calculating the amount of ink used in a printing press during a print job, the method comprising:
removably installing a cartridge having a chamber containing ink into an ink dispenser of a printing press, the chamber being defined by a tubular body, a fitment at a dispensing end having a least one outlet port closed by a valve, and a plunger slidably disposed in a open end opposite the dispensing end; prior to dispensing ink from the cartridge, weighing the cartridge in situ to determine an initial weight of the cartridge containing a first quantity of ink; dispensing ink from the cartridge during a print job until the print job is complete; prior to removing the cartridge, weighing the cartridge in situ to determine a ending weight of the cartridge containing a second quantity of ink; and subtracting the ending weight from the initial weight to determine the weight of the ink dispensed into the printing press during the print job.
