Special color-mixing method and special color-mixing equipment

Abstract

The present invention relates to a shaped colour-mixing method and its shaped colour-mixing device, in which between the colour-collecting roller and the roller closed to plate at least one shaped colour-mixing roller is set. The described colour-collecting roller can transfer at least more than two kinds of coloured printing inks to the described shaped colour-mixing roller, and any one point of the above-mentioned shaped colour-mixing roller surface can make relative movement of circular movement trace relatively to the surface of the roller contacted with it, and the radiuses of all the circular movement traces are identical. When the butt point of any two colour printing inks on the colour-collecting roller is contacted with the above-mentioned shaped colour-mixing roller, a circular colour-mixing zone using said butt point as centre of cycle and using radius as one-side axial serial quantity can be produced, and the butt line of above-mentioned any two colour printing inks is the colour-mixing zone formed from several above-mentioned circular colour-mixing zones.

Description

technical field [0001] The present invention relates to a special-shaped color mixing method and a special-shaped color mixing device, in particular to such a special-shaped color mixing method and a special-shaped color mixing device, in which a special-shaped color mixing roller is arranged between the color collecting roller and the forme roller of the ink supply system of the printing press , the special-shaped color mixing roller can form a uniform and gradual transition color between various color combinations of any shape passed down by the color collecting roller. Background technique [0002] In the field of printing, especially for printed matter (such as securities, banknotes, etc.) The use of instruments, such as fluorescent ink, microtext, magnetic ink, etc., has the advantage of high reliability, but the identification requires the use of instruments, and it is difficult to become a popular identification method. The second is the public anti-counterfeiting me...

Problems solved by technology

[0003] However, the currently known color mixing method is to add a color separation baffle in the ink fountain, then add two or more inks of different colors in the same ink fountain, and move the above two or Two or more inks mix colors, but this known color mixing method can only form a color mixing ribbon along the paper-feeding direction, and when the required color mixing area is any shape such as a circle, an ellipse, a curve, etc., due to the The inking roller moves in a straight line along the axial direction, so it is impossible to achieve uniform color mixing between various colors of arbitrary shapes
