Printing method using ink jet recording and printing apparatus

Abstract

A printing method that uses ink jet recording with a water-based ink set to form an image on a non-ink-absorbing or low-ink-absorbing recording medium, the method includes a printing step including recording with a color ink and recording with a resin ink performed after the recording with the color ink; and a drying step performed during the printing step and / or after the printing step. In the printing method, the water-based ink set includes the color ink containing a water-insoluble coloring agent and the resin ink not containing a coloring agent. The color ink contains the water-insoluble coloring agent, a resin component, a water-soluble solvent, and a surfactant. The resin ink contains a water-soluble resin solvent, a wax, and thermoplastic resin particles as a resin component that are insoluble in water but compatible in the water-soluble resin solvent. A content of the thermoplastic resin particles in the resin ink is 4% by mass or more and 12% by mass or less, and a content of the wax in the resin ink is 0.5% by mass or more and 6% by mass or less.

Description

BACKGROUND[0001]1. Technical Field[0002]The present invention relates to a printing method that uses ink jet recording to form an image on a non-ink-absorbing or low-ink-absorbing recording medium.[0003]2. Related Art[0004]Ink jet recording methods are printing methods in which recording is performed by causing small ink droplets to fly through the air and causing these droplets to adhere to a recording medium such as paper. With the recent innovative progress of ink jet recording technology, ink jet recording methods have been used even in a field of high-resolution image recording (printing) in which film photos and offset printing have been adopted. Thus, for example, one characteristic required for ink used for the ink jet recording methods is that small ink droplets can be discharged in a stable manner for a long time without disturbing the image.[0005]In recent years, there has been a demand that an image is formed using ink jet recording on a non-ink-absorbing or low-ink-abso...

Benefits of technology

[0009]Accordingly, an advantage of some aspects of the invention is to provide a printing method using ink jet recording that achieves high speed printing on a non-ink-absorbing or low-ink-absorbing recording medium and good abrasion resistance and that does not easily cause clogging in an ink jet head.

[0015]The printing method that uses ink jet recording according to an embodiment of the invention can provide a printing method using ink jet recording that achieves high speed printing on a non-ink-absorbing or low-ink-absorbing recording medium and good abrasion resistance and that does not easily cause clogging in an ink jet head.

Problems solved by technology

However, since the non-ink-absorbing or low-ink-absorbing recording medium is a recording medium that does not have an ink absorbing layer or a recording medium that has a scarce ink absorbing layer, ink is not absorbed or is not easily absorbed compared with the case of printing on a high-ink-absorbing recording medium.

Therefore, there is a problem in that the dried ink is easily detached due to abrasion.

In this case, however, it is difficult to ensure discharge stability in high speed printing due to high ink viscosity.

In addition, clogging in an ink jet head easily occurs.

Therefore, the amount of a coloring agent and a resin component added to ink is limited in consideration of achieving high speed printing and preventing clogging in an ink jet head.
