摘要:
A compact liquid ejection recording head capable of forming high-quality images at high speed includes large nozzles for ejecting large droplets, medium nozzles for ejecting medium droplets, and small nozzles for ejecting small droplets. The large nozzles are arranged on one side of an ink supply port, while the small nozzles and the medium nozzles are arranged on the other side of the ink supply port. The number of the small nozzles is larger than that of the medium nozzles, and that of the large nozzles. This allows high-quality and high-speed printing using the small nozzles, high-speed photo printing using the medium and small nozzles, and high-speed printing using the large nozzles.

A liquid-discharge recording head includes large nozzles for discharging large liquid drops and medium and small nozzles for discharging medium and small liquid drops that are smaller than the large liquid drops. The large nozzles are arranged on one side of an ink-supply opening and the medium and small nozzles are arranged on the other side of the ink-supply opening. The number of large nozzles is greater than the number of medium and small nozzles, and the liquid-discharge recording head performs high-speed printing using the large nozzles, high-speed photo printing using the medium and small nozzles, and high-quality photo printing using the small nozzles.

A first array state has a first nozzle group 50 provided with first nozzles 25a arranged at an array pitch d0, and second nozzle groups 51 each provided with first nozzles 25a arranged at an array pitch d1. The second nozzle groups 51 are disposed on both sides of a nozzle array, and the first nozzle group 50 is disposed therebetween. A second array state has a first nozzle group 50 provided with second nozzles 25b arranged at the array pitch d0, and second nozzle groups 52 each provided with second nozzles 25b arranged at an array pitch d2. The second nozzle groups 52 are disposed on both sides of a nozzle array, and the first nozzle group 50 is disposed therebetween. A diameter of each first nozzle 25a is set greater than that of each second nozzle 25b, and a volume of an ink droplet discharged is also greater. The array pitch d1 is set greater than the array pitch d2, and the array pitch d0 is set smaller than the array pitch d1 and the array pitch d2. This can prevent occurrence of a white stripe upon solid printing.
摘要:
An adverse effect of air flows occurring near the nozzle line with high print duty is reliably avoided by appropriately dividing and allocating the print data to a plurality of ink ejection nozzle lines. When the print head is scanning in a forward direction, a combination of a magenta ink nozzle line and a yellow ink nozzle line that do not adjoin each other is mainly used. When the print head is scanning in a backward direction, another combination of a magenta ink nozzle line and a yellow ink nozzle line that do not adjoin each other is mainly used.

摘要:
An ink jet recording apparatus and an ink jet recording method to prevent both of adjacent ejection orifice groups from operating at high duties. The method includes distributing image data such that the ejection duty of one of the adjacent ejection orifice groups is lower than a predetermined threshold in one scan and the ejection duty of the other ejection orifice group is lower than the predetermined threshold in another scan.
