Hereinafter, the present invention will be described in more detail with reference to Examples. First, the ink used will be described. 365nm wavelength
Or, by irradiating ultraviolet light of 254 nm,
As fluorescent pigments r, g, b that emit green and blue light, respectively,
Use the following. Red fluorescent pigment r; Y 2 O 2 S: Eu Green fluorescent pigment g; Zn 2 GeO 4 : Mn Blue fluorescent pigment b; Sr 5 (PO 4 ) 3 Cl: Eu 35 to 40 weight of these fluorescent pigments %, Add a binder,
A red light emitting ink R, a green light emitting ink G, and a blue light emitting ink B are produced. In addition, by combining these fluorescent pigments r, g, and b, a binder composed of rosin-modified phenol wax, vegetable oil, etc. is added in an amount of 60 to 70% by weight to produce a yellow light emitting ink Y, a magenta light emitting ink M, and a cyan light emitting ink C. I do. Yellow luminescent ink Y; red fluorescent pigment r + green fluorescent pigment g magenta luminescent ink M; red fluorescent pigment r + blue fluorescent pigment b cyan luminescent ink C; green fluorescent pigment g + blue fluorescent pigment b In order to produce each ink having the optimal balance, various compounding values of each fluorescent pigment were tested, and a table test was performed. An example of a good result is shown below. Yellow luminescent ink Y; Red fluorescent pigment r; 60 g Green fluorescent pigment g: 290 g Binder: 650 g Magenta luminescent ink M; Red fluorescent pigment r: 280 g Blue fluorescent pigment b: 60 g Binder: 660 g Cyan luminescent ink C; Green Fluorescent pigment g: 260 g Blue fluorescent pigment b: 80 g Binder: 660 g Next, plate making will be described. When printing with the red light emitting ink R, the green light emitting ink G, and the blue light emitting ink B (R, G, and B methods), the color negative is separated into normal colors, the yellow plate is turned into a blue plate, and the magenta plate is turned into green. And a color separation plate by combining the cyan plate with the red plate. When printing with yellow luminescent ink Y, magenta luminescent ink M, and cyan luminescent ink C (Y, M, C method)
Is subjected to normal color separation to obtain a color separation plate. Then, printing is performed as follows using the above-described ink and printing plate. Here, the printing paper is made of a material that does not contain a fluorescent whitening agent, and black color printing is difficult. Therefore, solid black printing is performed on the entire surface. On the paper, R, G, B or Y, M,
The picture is offset-printed by the C method. When the book is viewed under a fluorescent light, it looks as if the picture is printed with a medium-like transparent ink on a black paper. Irradiation of black light with ultraviolet light in a dark place reproduces a luminescent image.
