Description
Technical field
The utility model relates to medicine equipment, particularly a kind of hot transfer printing colour film for medical image thermal transfer printer.
Background technology
The civilian printing technique of existing routine mainly contains inkjet printing, stylus printing and laser printing.Stylus printing is mainly used in bill etc. and need to prints by multilayers such as carbon paper, and printing technique is main by little the having an injection of a plurality of intensive discharges on printhead, under the driving of motor, beats on carbon paper one by one.This carbon paper has a colour band in other words between printhead and carbon paper so, by the process dyestuff on colour band being printed on target paper, completes a stylus printing.The second is inkjet printing, and the raw material that inkjet printing print media used is printed is in other words mainly ink in fact, by the not mixed colour print of having taken target paper of color of the same race.The civilian printing of our routine is that three looks are printed or four looks are printed in general, it is by three primary colors or add a black and complete all colors and print, it is relatively abundant that the figure that this printing generates is imitated color level, but can't reach RGB level completely.The printer that is 13 kinds of colors for aim colour is to see on the market at present that best color is mixed to take maximum printers, and this printer is also used in other the print procedure of some papers rubber sheets at present.The third is laser printing, it is by printer processes, these graphical symbols to be formed to electrostatic coating on the surface of the laser drum of a special material making by a series of graphical symbol of computer export, forms in other words the static figure layer of different electric charges by certain voltage by the surface of this laser drum.When the toner cartridge of these laser drums has been experienced in the process of all static, if these static are sprayed onto any point, tiny powder all has adsorptivity, utilize this principle, carbon dust is placed on to the upper image that forms of laser drum, by paper package, around laser, rouse again, by power-off, allow carbon dust from laser drum watch crystal again, such process has just completed an electric transfer process doing carrier by laser drum.Above-mentioned three kinds of printing techniques are applied to the medical upper uncertainty that all has.The first stylus printing at all can not be for medical, prints, so it can not splice multiple color or with the figure of multiple intermediate color because it is a simple monochrome.Although the gorgeous degree of the second inkjet printing print colors is enough, but along with the consumption of carbon dust and the consumption length of ink-jet printer time with do not print the dry or wet degree of wait state China and Mexico machine under parse state in being exposed to air, the blocked degree of spout can cause image unstable of printing target paper.And for laser selenium drum printing technique, from the angle of transfer printing, its speed is very fast, produce electric charge, absorption carbon dust, shift carbon dust, this is a process very fast, but its shortcoming is because all powder are all solid-state, so it can not recall the very full color of level in last toning.
Present medical film printing technique is mainly divided into two classes, one class is called temperature-sensitive technology, the another kind of laser technology that is called, these two kinds of technology are all on conventional plastic-based film, to coat different coatings, thermal printer is by the method for heating, when having the film of dyeing coating layer through heating drum, the real time temperature that heating drum produces moment changes, and has caused finally and has formed color according to merging after these are ceaselessly destroyed by heat sensitive pigment above destination media.This is the film imaging of temperature-sensitive technology.For laser imaging, on the basement membrane of film, be coated with the solvent that one deck contains silver halide ion, laser head is strafing line by line in a horizontal manner, at point that should sensitization, give different strafing the time, cause length sensitive time of diverse location different, and then the sensitization of formation film, then through another one heating platform or heating drum, those are not finally vapored away by the residual solvent of sensitization, complete developing process.By current laser or temperature-sensitive technology, printing current film level is perfectly clear, but they have a defect is exactly the impact that they can only print GTG, for more and more requiring in the market colored image, comprise three-dimensional reconstruction, comprise and send the diagnostic techniques that special CT etc. is new all to depend on color diagnostic techniques, and current film printing technology can not be accomplished this point, if in conjunction with above-described civilian printing technique, image that can printing color, but very unstable, and there are a lot of drawbacks, and although laser film printing technique precision is very high, but can not form chromatic image, and not environmental protection.
