    摘要： To prevent a deficiency of ink supply in a high drive frequency inkjet head operating at low ambient temperatures, and to reduce temperature dependent ink squirting variations, an inkjet head is driven at an ink jetting cycle that compensates for temperature. In particular, the ink jetting cycle of a drive waveform includes a period tl of constriction of the pressure generation chamber (4), a period t2 of holding the drive voltage, and a process t3 of expansion of the pressure generation chamber (4). With a decrease in the ambient temperature of ink, the sum of the periods t1, t2 and t3 is changed from a time period which is (n + 1/4) (where n = 1, 2, 3) times as much as the cycle of inherent oscillation T of the pressure generation means to a time period which is (n + 3/4) times as much as T or to a time period which is (n-1/4) times as much as T. As a result, a low ambient temperature ink supply deficiency can be prevented without the use of an ink heater or the like.

    摘要： In the bi-directional printing, a reference correction value is set for correcting printing positional deviation arising between forward and reverse main scanning passes with respect to specific reference dots. An adjustment value is determined, using at least the reference correction value, to reduce printing positional deviation arising between forward and reverse main scanning passes. The printing positional deviation between forward and reverse main scanning passes is adjusted using the adjustment value. In a first adjustment mode, the adjustment value is determined by correcting the reference correction value with a relative correction value prepared beforehand for correcting the reference correction value.

    摘要： The technique of the present invention prevents a variation in hitting positions of two different types of ink droplets (IPs, IPm) ejected in two pixels, which adjoin each other in a main scanning direction, in response to a first driving pulse and a second driving pulse. The process of the invention drives each piezoelectric element on a print head in response to a driving signal, which may selectively include two different driving pulses in one recording cycle. When one dot is created in each of two adjoining pixels in the main scanning direction, either a driving signal A or a driving signal B is generated to control the dot creation. The driving signal A includes a first pulse in a first cycle and a second pulse in a second cycle, whereas the driving signal B includes the second pulse in the first cycle and the first pulse in the second cycle. The process regulates an ejecting speed (Vm1) of a small ink droplet (IPs) corresponding to the first pulse, an ejecting speed (Vm2) of large ink droplet (IPm) corresponding to the second pulse, and a variation in time difference between the ejecting timing of the first ink droplet and the ejecting timing of the second ink droplet in the case of a driving signal A and in the case of a driving signal B, according to a platen gap. This enables a distance (S3) between the hitting positions of the small ink droplet (IPs) and the large ink droplet (IPm) in the case of the driving signal A to be equal to a distance (S13) between the hitting positions of the small ink droplet (IPs) and the large ink droplet (IPm) in the case of the driving signal B.
