Ink-jet printing head and ink-jet printing apparatus and method |
摘要 |
The present invention provides an ink-jet printing head, and an ink-jet printing apparatus and method which enable not only larger-diameter nozzles but also smaller-diameter nozzles to be sufficiently recovered. In an ink-jet printing head according to the present invention, the number of smaller-diameter nozzles is larger than that of larger-diameter nozzles. Further, a plurality of ink channels include first ink channels in communication with the larger-diameter nozzles and second ink channels in communication with the smaller-diameter nozzles. The first ink channels and the second ink channels are mixed and arranged along an ink supply port so that a group of smaller-diameter nozzles composed of a plurality of the smaller-diameter nozzles is arranged between the lager-diameter nozzles.
