摘要： A inkjet recording apparatus includes a first inkjet head (12K,12M,12C,12Y) which ejects color ink having one of a hydrophobic property and an aqueous property; a second inkjet head (12T) which ejects colorless ink having the remaining the other property; and an ejection controller (32) which controls the first inkjet head to eject the color ink on. an image region and controls the second inkjet head to eject the colorless ink on an ejection region contacting the image region with a boundary therebetween. The ejection controller controls the first and second inkjet heads so that the colorless ink ejected from the second inkjet head reaches a second minute segment in the ejection region, the second minute segment adjacent to a first minute segment in the image region with the boundary interposed therebetween, before the color ink ejected from the first inkjet head reaches the first minute segment in the image region.

摘要： An aspect of the invention provides an inkjet printer including: an inkjet head and a controller. The inkjet head moves relative to a recording medium to perform printing. The inkjet head includes, a flow path unit (4) including plural pressure chambers (10) respectively communicating with plural ink ejection ports (8) that ejects ink droplets toward the recording medium, and a piezoelectric actuator (21) configured to take a first state and a second state. The controller supplies a drive pulse signal to the piezoelectric actuator in order to repeat an operation in which the piezoelectric actuator transits from the first state to the second state and returns to the first state, for enabling the corresponding ink ejection port to eject a plurality of ink droplets. The controller supplies the drive pulse signal so that timings of the transition and the return satisfy some relationships.

摘要： An ink jet printer (101) is provided with a passage unit (9), an actuator (21), and a pulse applying device (52). The passage unit (9) comprises a nozzle (108), a pressure chamber (110), and an ink passage (132) located between the nozzle (108) and the pressure chamber (110). The actuator (21) faces the pressure chamber (110) and comprises a first electrode (135), a second electrode (134) to which a reference potential can be applied, and a piezoelectric element (141) located between the first electrode (135) and the second electrode (134). The pulse applying device (52) is capable of applying a first voltage pulse to the first electrode (135) such that the nozzle discharges an ink droplet and a second voltage pulse to the first electrode (135) such that the nozzle (108) does not discharge the ink droplet. A voltage change on a leading edge and/or a trailing edge of the second voltage pulse is greater than a voltage change on a leading edge and/or a trailing edge of the first voltage pulse.

摘要： An ink jet printer (1) is provided with an ink jet head (2) and a controller (100). The ink jet head (2) comprises a nozzle (8), an ink chamber (El to E4) communicating with the nozzle (8), a pressure chamber (10) located between the nozzle (8) and the ink chamber (E1 to E4), and an actuator (20) that changes volume of the pressure chamber (10). The controller (100) controls the actuator (20) to perform a first performance. The first performance includes a first change in which the volume of the pressure chamber (10) increases and a second change in which the volume of the pressure chamber (10) decreases. A period from the first change to the second change is 2/3 x AL or below, or within a range between (2s - 1/2) x AL and (2s + 2/3) x AL. s is a positive integer. Discharging speed of ink discharged from the nozzle (8) is substantially maximum if the period from the first change to the second change is set to AL.
