摘要:
A reaction solution that is used for image recording with an ink containing a coloring material in a dissolved or dispersed state to destabilize the dissolved or dispersed state of the coloring material in the ink in contact with the ink to provide high quality and abrasion-resistant images, wherein the reaction solution contains at least a polyvalent metal ion and a nonionic polymer, the Ka value according to the Bristow method is from 1.3 mL·m−2·msec−1/2 to 3.0 mL·m−2·msec−1/2 inclusive, and the viscosity is from 20 mPa·s to 150 mPa·s inclusive.
摘要:
An ink jet recording apparatus has a pressure limiting mechanism between a gas-liquid separator and a source of negative pressure required to suck and supply ink for refilling an ink tank, to prevent a fixed amount or more of negative pressure from being exerted on the gas-liquid separator.
摘要:
An ink-jet recording apparatus, it is possible to assuredly execute replenishment of ink into an ink tank and control of a pressure within the ink tank during ink replenishment by a simple configuration, and reduce the size and the weight of the apparatus, and improve reliability of the apparatus. The ink-jet recording apparatus includes an ink tank for receiving ink from an ink intake, an ink supply unit for receiving ink from a replenishing tank into the ink tank by a negative pressure introduced from a suction port of the ink tank in the inside of the ink tank, and a negative-pressure controller for causing the negative pressure within the ink tank to remain in an ink supply channel from the replenishing tank to the inside of the ink tank, so that the negative pressure within the ink tank does not return to an atmospheric pressure while receiving ink.
摘要:
A residual ink container comprising laminated members for absorbing residual ink not used for recording, wherein the laminated members are laminated with a gap between adjacent ones of the members; and a covering member covering such that non-contact portion is provided between the covering member and a topmost one of the laminated member so as not to press against the topmost one.
摘要:
An ink set which comprises a black ink containing an aqueous medium and a pigment dispersed in the aqueous medium by an action of an ionic group, and at least two color inks each containing a coloring material and an aqueous medium, wherein (i) respective images formed with the respective color inks have the same &Dgr;E or have the difference in &Dgr;E that is 10 or less in a CIELAB color space display system in a fading test under conditions that cause fading corresponding to pseudo-indoor sunlight fading through a window for 3 years or more, and (ii) at least one of the color inks contains at least one of a coloring material and an additive that destabilize dispersion stability of the pigment in the black ink. The ink set can provide a high quality multicolor image keeping color balance after long preservation and showing less bleeding between black and color regions.
摘要:
For the sake of achieving both the size and weight reductions of a printing apparatus and increasing the reliability thereof, an ink tank is provided with a gas-permeable member that permits air to pass without permitting ink. The ink tank is capable of introducing ink through an ink inlet by negative pressure introduced in the ink tank through a common suction port.

Provided is an inexpensive vehicular communication apparatus capable of transferring image data containing a record of an accident to a safe, external location, the apparatus being usable in an ordinary automotive vehicle. The apparatus includes an image sensing device, a data storage device for storing image data that has been captured by the image sensing device, a sensor for sensing impact, a portable-terminal holding device in which a portable terminal is capable of being placed, and an operation controller which, if impact has been sensed by the sensor, is for notifying a prescribed party via the portable terminal unless the portable terminal is removed from the portable-terminal holding device within a predetermined period of time.
摘要:
An ink-jet printing apparatus, an ink-supplying apparatus, and a method for supplying ink are configured so that a mode of ink supply is changed to another mode, for example the mode of supplying ink to an ink tank is changed to another in accordance with a fact that a next page is intended to be printed or not, when an ink tank that requires the supply of ink is detected, with the result that the printing speed is increased.
