Abstract

The invention provides a printing sheet, it is desirable that a print sheet be provided which can be smoothly inserted between a thermal head and a platen which are in contact with or almost in contact with each other. A print sheet which is transported by transporting means and inserted between a thermal head and a platen which are disposed to oppose to each other in a printing unit of a printer, which is to be used for printing, includes: a chamfered portion to decrease the sheet thickness of at least one surface of the front and rear surfaces and which is formed at the end portion in the supply direction of the printing unit. The chamfered portion forms tape shape, which has a dimension in a thickness direction y equal to or less than t / 2 mm in the case where the sheet thickness is t and a dimension x in a longitudinal direction in the range of 0.05 to 0.5 mm from the end in the feeding direction, and an inclination angle [theta] of a cut-off imaginary line is equal to or less than 30[deg.].

Description

technical field [0001] The present invention relates to a kind of printing paper suitable for printing without leaving blanks on the edge and transferring desired characters and images on the entire surface of the paper. Background technique [0002] In recent years, in order to meet the requirements of high resolution, multi-grayscale or high-speed printing, color printers mostly use thermal printers equipped with thermal heads. components to form. [0003] The thermal head of the thermal printer is arranged on the printer body by mounting the substrate on the thermal head mount. When recording, by rotating the above-mentioned thermal head installation platform, the printing paper can be directly touched when printing on thermal paper, and when printing by melting transfer and sublimation, it is separated by substrate materials such as transparent PETP film and PEN film. The ink film that forms the ink layer on one side and printing paper such as plain paper and OHP paper...
