Referring to fig. 1, in one embodiment of the present invention, a transfer method is provided for applying a ribbon 30 comprising a color coating 31 and a special coating 32.
The transfer printing method comprises the following steps:
step S100, obtaining a transfer image;
step S200, obtaining image area printing data and non-transfer area printing data according to transfer image processing;
step S300, printing the colored coating 31 of the ribbon 30 on the intermediate transfer medium 50 according to the image area printing data to form a first printing image;
step S400, transferring the surface layer component of the intermediate transfer medium 50 onto the special coating 32 of the ribbon 30 according to the non-transfer region printing data to form a second printing image, wherein the image combined by the second printing image and the first printing image corresponds to the transfer image;
step S500, the first print image on the intermediate transfer medium 50 is transferred to the print medium 40 according to the image area print data.
In this embodiment, since the intermediate transfer medium 50 cannot directly contact the printing medium 40 and sticks to the printing medium 40, the isolation of the intermediate transfer medium 50 from the printing medium 40 during transfer is achieved by the special coating 32.
The print to the intermediate transfer medium 50 is a first print image of the print data of the corresponding image area formed by the printing of the colored coating 31 of the ink ribbon 30, and the position of the intermediate transfer medium 50 corresponding to the print data of the non-transfer area is transferred to the special coating 32 of the ink ribbon 30 to form a second print image without any coating on the intermediate transfer medium 50, i.e. the second print image on the intermediate transfer medium 50 is actually a blank image on the bottom layer of the intermediate transfer medium 50, without the surface layer component of the intermediate transfer medium 50 nor any coating of the ink ribbon 30. The first printed image of the intermediate transfer medium 50 is transferred to the printing medium 40 by heating or the like, and the second printed image of the intermediate transfer medium 50 is not transferred to the printing medium 40 even by heating or the like due to the lack of the surface layer component, and a non-transfer region free of any component is formed on the printing medium 40.
The first printed image of the intermediate transfer medium 50 is transferred to the printing medium 40 by heating or the like, and the second printed image of the intermediate transfer medium 50 is not transferred to the printing medium 40 even by heating or the like due to the absence of the surface layer component, and the second printed image is retained on the intermediate transfer medium 50. Then for print medium 40, the only first printed image transferred thereto, the non-transferred area corresponding to the second printed image is devoid of any coating on ribbon 30, the non-transferred area facilitating the placement of the magnetic stripe placement site, the IC receiving site, and the signature column of the owner.
If step S400 is not performed, the intermediate transfer medium 50 is in contact with the print medium 40 during the transfer process, and when heated, the surface layer component of the intermediate transfer medium 50 corresponding to the second print image position may be transferred to the print medium 40, thereby affecting the arrangement of the magnetic stripe arrangement portion, the IC storage portion, and the signature column of the owner.
Further, for step S200, obtaining image area print data and non-transfer area print data according to the transfer image processing includes the steps of:
transforming the image area in the transferred image into first coordinate data corresponding to the thermal print head by image data analysis software or the like; in this step, the image area in the transfer image is scratched out and put on a two-dimensional coordinate system, each pixel point of the image area is represented by two-dimensional coordinates (x, y), and typically x and y take positive integers so as to correspond to a heating element of the thermal print head; the image area of the transferred image is an area of the transferred image corresponding to the image to be transferred on the printing medium 40 through the colored coating 31 of the ink ribbon 30, that is, an area of the transferred image except for the transfer area;
converting an image area having RGB as a color component in the transfer image into color data having YMC as a color component; in addition, the image area having Bk (black) as a color component in the transferred image is subjected to a dither transformation which is usually performed in the case where the ink of the Bk coating layer of the ink ribbon 30 is a molten ink, but the dither transformation is performed on the colored coating layer 31 even in the case where the colored coating layer 31 of the ink ribbon 30 is a molten type;
transforming the non-transfer region in the transferred image into second coordinate data corresponding to the thermal print head; in this step, the non-transfer region in the transfer image is scratched out and put on a two-dimensional coordinate system, and each pixel point of the image region is represented by two-dimensional coordinates (x, y) with the intersection position of the lower end and the left end of the transfer medium generally taken as an origin O (0, 0), and typically x and y take positive integers so as to correspond to a heating element of the thermal print head.
The first coordinate data and the color data together form image region printing data; the second coordinate data directly constitutes non-transfer area print data.
Referring to fig. 3, it should be noted that, generally, the colored coating 31 of the ink ribbon 30 includes a Y (yellow) coating, an M (magenta) coating, a C (cyan) coating, and a Bk (black) coating. Of course, in other embodiments, the colored coating 31 may take other colors according to different rules. In addition, in this embodiment, the special coating layer 32, i.e., the I-coating layer, is immediately behind the colored coating layer 31, and the special coating layer 32 is specifically made of polyester, and can be adsorbed by heating with the surface layer component of the intermediate transfer medium 50.
Further, the transfer printing method further comprises the steps of: when the non-transfer region in the transfer image is converted into second coordinate data corresponding to the thermal print head, edge enhancement conversion is performed. That is, the edge data of the second coordinate data is increased by 1 or 2 pixels, so that the heating area of the first thermal print head 13 is slightly larger than the non-printing area and the edge is outwardly expanded by 1 or 2 pixels, so that the surface layer component of the intermediate transfer medium 50 transferred onto the special coating 32 is slightly larger than the non-printing area and the edge is outwardly expanded by 1 or 2 pixels, and no image exists at the edge of the non-printing area.
