Embodiment 1
[0134] (1) Modulation of fluorescent latent image image offset printing ink
[0135] "Product Information Code Printing Ink" (b-2-1) for printing the fluorescent latent image (B-2-1) of the product information code was prepared. A red fluorescent luminescent dye-1 (organic europium complex dye) was prepared as a fluorescent dye that is colorless to the naked eye and emits red light when excited by ultraviolet rays. Fully knead 78.0 parts of varnish for offset printing ink, 5.0 parts of polyethylene wax and 7 parts of ink solvent, knead 10 parts of the above red fluorescent pigment-1, and prepare red fluorescent offset printing ink-1. Among the above, the blended varnish for offset printing ink is made by using rosin-modified phenolic resin, vegetable oil-modified isophthalic alkyd resin and soybean oil as main components, and adding ink solvent and aluminum chelate. In order to observe the optical properties of the red fluorescent pigment-1, the above-mentioned red fluorescen...
Embodiment 2
[0147] (1) Preparation and printing of fluorescent inkjet printing ink
[0148] Prepared red fluorescent light-emitting ink-jet ink b-2-1, it comprises 6 parts of red fluorescent light-emitting pigments-1 used in the above-mentioned embodiment 1 (1) and 10 parts of acrylic resin (methacrylic acid) as binder Methyl ester - butyl acrylate - methyl hydroxyethyl acrylate, 60:30:10), using butanone (hereinafter referred to as MEK) and propylene glycol monomethyl ether acetate (hereinafter referred to as PGMA) (1 : 1) as a solvent.
[0149] Similar to Example 1 (3), four-color offset printing was performed using the "commodity image printing ink" (a-1) of Example 1 (2). A piezoelectric inkjet printer connected to a personal computer is prepared. The barcode of the product information code is printed on the text near the product image and on the white background part using the above-mentioned red fluorescent inkjet ink b-2-1 according to the product information code screen prepared...
Embodiment 3
[0153] (1) Printing of printed matter linked to IT shopping
[0154] We prepared printing plates for offset printing this IT shopping linkage print. Since one side of the division of a product is about 5 cm, a product information code printing plate with a side of the QR code representing the product information code of 20.5 mm and a cell size of 0.50 mm was made. As the printing plate of the photo image of the product, three printing plates of blue, red, and yellow were made with a screen line count of 175 lines. The plate is made in such a way that the printed portion overlapping the light-emitting portion of the QR code unit is inconspicuous to the naked eye, but the fine parts that are not printed are scattered, so that the QR code can be reproduced during image processing. Set the above blue, red, yellow printing plates and the printing plates of the two-dimensional code on the four-color offset printing machine. Using the ink for three-color offset printing of the blue...
