Abstract

A thermosensitive recording sheet includes a support and three thermosensitive coloring layers overlaid on the support. A print is produced by image recording to the recording sheet. A colorless gloss indicia is recorded by thermal recording, and discernible according to a glossiness difference. In a preferred embodiment, an image reading device comprises an image reader for reading an image from an original. A glossmeter unit measures glossiness of respectively unit areas in the original. An arithmetic operation unit obtains an average glossiness of the glossiness of respectively the unit areas. An indicia discriminator checks existence of a gloss indicia according to a glossiness difference between the glossiness of respectively the unit areas and the average glossiness. A controller allows the image reader to operate if the gloss indicia lacks, and generates an alarm signal if the gloss indicia exists.
