[0255] 7. Examples 1-5, Comparative Examples 1-3, Reference Examples

[0256] Continuous printing was performed for 1 hour using the colored inks shown in Table 3 and Table 4 below. Thereafter, suction treatment and rinsing treatment by the capping operation were performed, and wiping treatment (cap cleaning) was performed using the wiping member containing the immersion liquid shown in Table 3 and Table 4 below. Next, when continuous printing and cap cleaning were performed again in this order for 1 hour, the following evaluations were implemented. Evaluation items and evaluation methods are as follows.

[0257] 7-1. Continuous recording stability

[0258] When printing 7 sheets of A1-size vinyl chloride film, 30 pieces of T-shirts, and 10m professional photo paper, observe whether there are missing ink dots and whether there is any drop deviation of the colored ink ejected from the nozzle. It should be noted that when the evaluation of the continuous recording stability i...

Abstract

An ink jet recording apparatus includes at least: a print head that discharges ink jet recording ink from nozzles which are formed on a nozzle forming surface toward a recording medium; a wiping mechanism that wipes out ink which is attached to a nozzle forming surface using an absorbent material having an impregnating solution; and a cap member that adheres closely to the nozzle forming surface in a state in which a space is included in an area facing the nozzles, and removes at least ink of the space, and further includes the following characteristic (1) or (2). (1) Ink jet recording ink composition includes a first resin having a heat distortion temperature of 10° C. or less. (2) Ink jet recording ink composition includes a second resin and includes substantially no glycerin.

Description

technical field [0001] The present invention relates to an inkjet recording device. Background technique [0002] Conventionally, in the printing method using the inkjet recording method, printing is performed by flying ink droplets and attaching them to a recording medium such as paper. In the field of high-definition image recording (image printing) using photographs and offset printing, inkjet recording devices using inkjet recording methods have also been used due to the innovative progress of inkjet recording technology in recent years. [0003] In an inkjet recording device, when water and other volatile components contained in ejected ink evaporate, the viscosity of the ink increases (thickening). The thickened ink causes clogging of the nozzles, resulting in poor ink discharge. In recent inkjet recording, in order to perform high-definition recording, the amount of ink droplets to be ejected is as small as several pL, the diameter of a nozzle ejecting ink is reduce...
