Embodiment 1

[0022] A laser printing method, characterized in that it includes: when the printing film passes through the fixing roller 4 of the laser printer, the carbon powder 5 transferred to the printing film is fused 3 together with the composite resin coating 2 on the surface of the printing film to form image.

[0023] The current world medical film market is mainly provided by five companies, AGF (Agfa), Kodak (Kodak), FujiFilm (Fuji Film), Konica (Konica), and SONY (Sony). Medical film consumables adopt dry laser imaging film technology and dry thermal imaging technology. The laser printing film provided by the present invention uses laser printing imaging technology when printing, which has different technical characteristics and principles from dry laser imaging technology and dry thermal imaging technology.

[0024] The principle of the current color laser printer fixing is: during the working process of the laser printer, the toner 5 (mainly composed of composite polymer resi...

Embodiment 2

[0029] A laser printing film, comprising a base 1, characterized in that the surface of the base 1 is coated with a coating 2, the coating 2 includes a composite resin, and the composite resin component and the resin component of the carbon powder 4 can Fusion occurs 3.

[0030] Therefore, using the above-mentioned laser printing film provided by the present invention has the following advantages: (1), the film coating does not contain silver salt, the production cost is low, and it is environmentally friendly; (2), it can output color images, and its extended application is wider , such as 3D reconstructed medical color image output, medical angiography color image output, medical endoscope color image output, etc., but also suitable for non-medical printing; (3), the output image is clear, the imaging is good, and the resolution of the output image is Not less than 1200Dpi, the grayscale reaches 16Bit, the printing speed (A3 format) is greater than 16 sheets / minute, and the ...

Abstract

The invention discloses a laser printing method. The laser printing method is characterized by including the steps that when a laser printing film passes through a fixing roller of a laser printing machine, carbon powder transferred to the laser printing film and a coating on the surface of the laser printing film are fused together to form images, and the coating comprises composite resin. The laser printing film used for the laser printing method comprises a film base and is characterized in that the film base is coated with the coating, the coating comprises the composite resin, and ingredients of the composite resin and ingredients of the carbon powder can be fused. The laser printing method and the laser printing film can be used for outputting color images, have wider extensive application such as 3D reconstructed medical color image output, medical radiography color image output and medical endoscope color image output, and can be suitable for non-medical printing.

Description

technical field [0001] The invention relates to a laser printing method and a film for laser printing. Background technique [0002] As we all know, laser printers have a wide variety of printing media, from ordinary printing paper, copy paper, to high-end color laser paper, cameras, coated paper, PE film, etc., but not all media are suitable for printing medical images. Because it has its own special requirements to reproduce high-quality medical imaging images. For example, the optical density value (transmittance), clarity, contrast, gray scale and level, and resolution of a photo all affect the image quality. In addition to meeting the needs of diagnostics, high-quality medical imaging photos should also have suitable density, good contrast, excellent clarity, minimal distortion and noise, and at the same time meet the usage habits of clinicians. Inferior photo media may result in missed or misdiagnosed clinical cases. [0003] Moreover, currently used printing media ...
