Problems solved by technology

However, this technique is based on the so-called solid inkjet recording method and is not applicable to ordinary inkjet recording methods
[0010] Assuming that even if this technology can be applied to a general inkjet method, in order to form a film over the entire image surface, the amount of transparent resin used will be very large, resulting in an increase in cost, while in the ink container of a general inkjet recording device If the liquid substance of the transparent resin cannot be placed, there will undoubtedly be problems such as remodeling the device and increasing the size of the device.

Embodiment 1

[0147] (1) Modulation ink set

[0148] An ink composition composed of the following components was prepared as an ink set. Each ink composition was prepared in the following order. That is, the pigment, dispersant and water are mixed, placed in a sand mill (manufactured by Yaskawa), and dispersed with glass beads [diameter=1.7mm; dosage: 1.5 times (weight) of the mixture] for two hours, and then Take out the glass microspheres and prepare a pigment dispersion.

[0149] Next, mixing ingredients other than the pigment and the dispersant as an ink solvent, and while stirring the above-mentioned pigment dispersion liquid, the above-mentioned ink solvent was slowly added dropwise, and stirred at room temperature for 20 minutes. It was filtered through a 5 μm membrane filter to prepare an ink composition for inkjet recording.

[0150] The compounding components of each ink composition are shown below.

Embodiment 2

[0207] In an inkjet printer (PM-770C; manufactured by Seiko Epson Co., Ltd.), an ink cartridge containing five pigment ink compositions (all five colors) and one clear ink composition composed as shown below was installed. Adjust the ejection amount of the transparent ink so that when the ink coverage of the pigment ink composition is low, increase the ejection amount of the transparent ink composition; when the ink coverage of the pigment ink composition is high, reduce the ejection of the transparent ink composition Specifically, adjust the ink coverage ratios of the two ink compositions to the values ​​(10 modes) shown in Table 4, and form the corresponding ink coverage on the recording medium (dedicated glossy film; manufactured by Seiko Epson Co., Ltd.). rate printed images. In this process, the pigment ink composition and the transparent pigment composition are ejected from the print head to form an image during the same process. The glossiness of the obtained image was...

Embodiment 3 and comparative example 3

[0281] In addition to changing the single-color pigment ink composition to a mixed-color (multiple) pigment ink composition, the recording methods of Example 2 and Comparative Example 2 were used to obtain the gloss ratio. The results are shown below. At this time, as in the case of using a single-color ink composition, when printing, when the ink coverage of the pigment ink composition (all mixed color ink compositions) is high, reduce the ink coverage of the transparent ink composition; when the pigment ink composition When the ink coverage of the transparent ink composition is low, increase the ink coverage of the transparent ink composition. And the gloss ratio at this time is the maximum / minimum value of the gloss when the ink coverage ratio of the printed pigment ink composition is 1:1 (dual-color) or 1:1:1 (three-color) in one pass. value.

Abstract

The present invention provides an ink jet recording method and an ink set, capable of easily providing a printed matter excellent in weatherability and greatly reduced in glossiness unevenness without involving a cost increase, and a modification to or size increase of an ink jet recording device, and an ink jet recording method and a printed matter using this, capable of providing a high-quality image small in duty-dependent glossiness ratio (maximum value / minimum value). An ink jet recording method which jets a pigment ink composition and a resin-component-containing clear ink composition for recording on a recording medium, characterized in that the jet amount of the pigment ink composition and / or the jet amount of the clear ink composition are regulated so that a practically uniform glossiness is given to the entire recording surface of the recording medium after recording.

Description

technical field [0001] The present invention relates to an inkjet recording method capable of providing an image with substantially uniform gloss, an ink set, and a recorded matter using these. In more detail, the present invention relates to an inkjet recording method, an ink set, and a gloss ratio (maximum value / minimum value) based on a duty (duty) that can obtain a high-gloss record that is excellent in weather resistance and has low gloss defects. An inkjet recording method of high-quality images and a recorded matter using the same. Background technique [0002] The inkjet recording method is a method of flying ink droplets and attaching them to a recording medium such as paper for printing. In recent years, with the innovation and development of inkjet recording technology, the inkjet recording method has been applied to the field of high-definition printing that could only be achieved by silver halide photography and offset printing in the past. As a result, inkjet...
