Abstract
PURPOSE: To obtain a printed matter which is effective to protection against the the reproduction and forgery made by means of all color copying machines, by a method wherein two kinds of inks which have approximately equal color tone and a difference being more than a given value, in a deflection rate at a wave length range.
CONSTITUTION: There are used two kinds of inks which have an uniform tone of color but have a difference of 5% or more in a deflection rate at a wave length in one of wave lengthes within a wave length range of 650W700nm. Most part of a printed matter 1 is printed in a an ink B, and a part of it is printed in an ink A. If said printed matter 1 is copied by means of a color copying machine, a difference in a color phase and lightness between a part of portion 2 and a remaining portion is caused on a matter 1' to be copied, and thereby it can be visibly found that it is a reproduction matter.
