<p>There is provided a thermal transfer printing method capable of forming a screen on a photographic paper without providing a margin between the screen and a screen adjacent thereto, and of maintaining an image quality of the screen. In the thermal transfer printing method according to the present invention, a photographic paper 2 is firstly unwound from a photographic paper roll 3 and the photographic paper 2 is sent. Then, with the use of an ink ribbon 14 having a yellow layer 15, a magenta layer 16, and a cyan layer 17, a screen 6 having an image is formed on the photographic paper 2, by transferring a yellow colorant, a magenta colorant, and a cyan colorant onto the photographic paper 2 by sublimation by means of a first heating means 10, without providing a margin between the screen and a screen adjacent thereto. Then, the photographic paper 2 is cut by means of a cutting means 19 at a rear edge 6a of the screen 6 so as to manufacture an individual photographic paper 4 on which the screen 6 has been formed, and the individual photographic paper 4 is conveyed to a second heating means 20. Then, with the use of a screen protective ribbon 24 having a screen protective film 25, a screen protective layer 24 is formed on an overall surface of the screen 6 formed on the individual photographic paper 4, by thermally transferring the screen protective film 25 onto the overall surface of the screen 6 formed on the individual photographic paper 4 by means of the second heating means 20.</p> |
