Abstract

A method of coating an image-recorded surface of printing paper, which surface is formed by attaching a coloring agent to the printing paper in accordance with a recording signal. A coating agent comprising a hot-melt material is supported in the form of a thin film on a surface of a porous support member, and the coating agent in the form of the thin film is brought into contact with the image recorded surface and heated so as to transfer the hot-melt coating agent to the image recorded surface through pores of the support member in an amount corresponding to that used for coating.

Claims

1. A method of coating an image-recorded surface of printing paper, which surface is formed by attaching a coloring agent to the printing paper, in accordance with a recording signal, comprising the steps of:

supporting a transparent coating agent made of a hot-melt material, in the form of a thin film, on a sheet-like member to oppose the image recorded surface;

forming a linear heating region elongated in a widthwise direction of the printing paper;

forming a two-dimensional coating region by moving the printing paper and the sheet-like member towards the heating region; and

bringing the coating agent, which is in the form of the thin film, into contact with the image-recording surface, while heating the coating agent, thereby transferring the hot-melt coating agent onto the image-recorded surface.
