The wind velocity of the air injected by the air-blow dryers 7a, 7b is lower than that of the air injected by the air-blow dryers 7c, 7d. That is, since a large amount of moisture remains on the front surface M1 of the printing medium M passing through the air-blow dryers 7a, 7b, the printing medium M is dried while the flow of the aqueous inks is suppressed by injecting the air at a lower wind velocity. On the other hand, the moisture decreases on the front surface M1 of the printing medium M dried by the air-blow dryers 7a, 7b and the fluidity of the aqueous inks is reduced. Accordingly, the drying of the printing medium M is promoted by injecting the air at a high wind velocity to the printing medium M passing through the air-blow dryers 7c, 7d.

A printhead is provided having an elongate support having a plurality of internal webs protruding from a base section to define a plurality of parallel fluid supply channels, a shim supported by the support and defining a plurality of rows of openings through which fluid from respective supply channels is supplied, and a plurality of elongate printhead modules supported serially on the shim. Each module defines a plurality of fluid supply passages through which fluid passes to fluid ejection nozzles from respective rows of the openings. Either end of each module defines complementary formations such that adjacent modules nest together.

In some examples, a piezoelectric printhead assembly can include a plurality of piezoelectric micro-electro mechanical system (MEMS) dies, and application-specific integrated circuit (ASIC) dies electrically connected to the piezoelectric MEMS dies.

A liquid ejection head, including: a first head unit; a second head unit shifted with respect to the first head unit in both of a first direction in which nozzles of the head units are arranged and a second direction orthogonal to the first direction and disposed so as to overlap the first head unit in the second direction; and a first wiring member having flexibility and drawn from the second head unit in the second direction toward the first head unit, wherein the first wiring member includes a large-width portion on which a drive circuit is mounted and a small-width portion having a width in the first direction smaller than a width of the large-width portion in the first direction, and wherein the small-width portion passes through a space existing next to the first head unit in the first direction and extends in the second direction.

A flow path structure which forms a flow path of liquid, includes: a light absorbing member (first substrate) having absorbing properties with respect to laser light; a light transmitting member (second substrate) which is joined to the light absorbing member and has transmitting properties with respect to the laser light; a first flow path (flow path) which is surrounded by a welding interface between the light absorbing member and the light transmitting member; and a second flow path which is formed in a flow path pipe (flow path pipe) which protrudes from a front surface opposite of the welding interface in the light transmitting member, and communicates with the first flow path, in which the flow path pipe is included in a region of the first flow path in a plan view from a direction orthogonal to the welding interface.

A system (20) and method for printing on clear polymeric film web (24) are disclosed. A first stationary inkjet print unit (44, 60, 70, 82) has first ejection nozzles that span a width of the clear polymeric film web and a second stationary inkjet print unit (44, 60, 70, 82) has second ejection nozzles that span the width of the clear polymeric film web. A web transport conveys the clear polymeric film web past the stationary inkjet print units. First and second print controllers operate the first and second and stationary inkjet print units to deposit drops of a first and a second material on the clear polymeric film web at a first and a second resolution, respectively. In addition, dimensions and position of a page element to be printed on the clear polymeric film web are adjusted to compensate for distortion that may occur to the printed page element due to shrinking of the clear polymeric film web.
