Inkjet recording device

Abstract

In an inkjet recording device using ink, the phase of which changes between a gel state or a solid state and a liquid state depending on temperature, when a recording medium fixing means is applied in which a recording medium is sucked and fixed by air suction via adsorbing holes contacting the recording medium, it is prevented that the pattern of the adsorbing holes appears on an image. The recording medium fixing means (2) for sucking and fixing a recording medium (M) by air suction via adsorbing holes (61) contacting the recording medium has: a recording medium holding layer (6) in which adsorbing holes are formed and a temperature by which ink becomes a gel state or a solid state is maintained; and a supporting layer (7) configured with at least one layer for supporting the recording medium holding layer and having suction holes (71) formed so as to communicate with the adsorbing holes. The opening area at the opening end of the adsorbing holes, which contacts the recording medium, is made smaller than the opening area at the opening end of the suction holes, which contacts the recording medium holding layer. This reduces the difference between the temperature above the adsorbing holes and the temperature above the member around the adsorbing holes and prevents the pattern of the adsorbing holes from appearing on an image.

Description

technical field [0001] The present invention relates to an inkjet recording device. Background technique [0002] In recent years, the inkjet recording method, which can record high-definition images with a relatively simple device, has been rapidly developed in various aspects. In addition, there are various uses, and therefore, a recording medium or ink is used according to each purpose. In particular, in recent years, a significant increase in recording speed has also been found, and development of an inkjet recording device having performance that can also withstand light-weight printing applications is also progressing. [0003] In order to eject ink smoothly from the fine nozzles of the inkjet recording head, it is preferable that the ink has a relatively low viscosity. [0004] However, when ink with a relatively low viscosity is ejected and lands on a recording medium, there is a problem of image quality degradation as follows. [0005] First, in the case of a rec...

Problems solved by technology

[0004] However, when ink with a relatively low viscosity is ejected and lands on the recording medium, there is a problem of image quality degradation as follows

[0005] First, in the case of a recording medium with low ink absorbency, a phenomenon called bleeding occurs in which colors are mixed between different colors, and a phenomenon called beading occurs in which the color shades of the same color become beaded. Phenomenon that causes image quality degradation

[0006] In the case of paper media such as plain paper with a fast ink absorption rate, a phenomenon called bleeding occurs in which irregular penetration occurs along the fibers of the paper, and a phenomenon called bleed-through occurs in which ink permeates to the back. , it becomes a big cause of image quality drop even if it is plain paper
