Description
【発明の詳細な説明】 〔産業上の利用分野〕 本発明は新規の印刷方法に関するものである。[Detailed description of the invention] [Industrial application field] The present invention relates to a new printing method.
従来、印刷方法としては、オフセット印刷方式によるイ
ンク印刷方法等が知られている。Conventionally, as a printing method, an ink printing method using an offset printing method is known.
オフセット印刷方式は、湿し水を使用してインクの付着
を制御しているため、湿し水とインクの混合による画質
の劣化などの、湿し水使用による不利益が多いのが現状
である。The offset printing method uses dampening water to control ink adhesion, so there are currently many disadvantages due to the use of dampening water, such as deterioration of image quality due to mixing of dampening water and ink. .
本発明の目的は、安定して高画質な転写画像を可能にす
るような新規の印刷方法を提供することである。An object of the present invention is to provide a novel printing method that enables stable transfer images of high quality.
すなわち本発明は、画像形成基板のインク反撥性表面に
、画像情報に対応した電界パターンを形成し、インクを
接触させることにより該電界パターンに対応したインク

を特徴とする印刷方法である。That is, the present invention forms an electric field pattern corresponding to image information on the ink-repellent surface of an image forming substrate, forms an ink image corresponding to the electric field pattern by bringing ink into contact with it, and transfers the ink image to the transferred surface. This is a printing method characterized by transferring the image onto the body.
以下に本発明の基本的なプロセスを述べる。The basic process of the present invention will be described below.
（１）インク反撥性表面層の作成工程 まず、画像形成基板にインク反撥性表面層を作成する。(1) Creation process of ink-repellent surface layer First, an ink-repellent surface layer is created on the imaging substrate.
この際、インクが接触しても付着しないインク反撥性表

れない。At this time, the ink-repellent material used to form an ink-repellent surface that does not adhere even when ink comes into contact with it is one with a coating surface energy of 25 dyn Hcm-1 or less, such as silicone resin, fluorine resin, etc. can be mentioned. Surface energy is 25 d y n-crrL
If it exceeds -', the ink repellency decreases and the ink also adheres to non-electric field pattern areas, making it impossible to obtain a good image.

An electric field pattern corresponding to image information is formed using the ion implantation type disclosed in Japanese Patent No.-53537 and the like.

行なうことができる。(3) Ink image forming step The electric field pattern portion formed by the electric field obtained in accordance with the image information on the ink-repellent surface has polarity, thereby improving wettability to the ink. When ink is brought into contact with this ink-repellent surface, ink adheres to the electric field pattern that has become ink-adhesive due to electrostatic induction or the like, forming an ink image. On the other hand, since the area other than the electric field pattern portion on the ink-repellent surface has no polarity, ink does not adhere to the area. Various means can be used to deposit ink onto the electric field pattern. One embodiment of a preferred method involves contacting an ink-soaked sponge roller with an ink-repellent surface to form an ink image. With this method, the adhesion force of ink to the sponge roller is superior to the slight ink adhesion force in the non-electric field pattern area, so ink does not adhere to the non-electric field pattern area, and stains in the non-image area are extremely reduced. - (4) Printing process The ink image is transferred to a transfer target such as paper. By utilizing the difference in ink adhesion between the ink image once formed and the ink-repellent surface, that is, the difference between the ink adhesion on the ink image and the ink non-adhesion on the non-ink area, the ink that remains thinly on the ink image area is removed. Reprint printing can be performed by applying ink to the surface of the ink, forming an ink image again, and transferring it to the object to be transferred.
