A securing method for securing an object comprising the following steps: a) establishing a device independent colour coordinate system with variables (s 1, s 2,...,s n) n>=2 being the number of coordinates of said system with the variables (s 1, s 2,...,s n) defined in the physically feasible colour domain, b) establishing a pair of variables A, B from among the coordinates (s 1, s 2,...,s n) from the space of coordinates of a colour space, with A and B being different coordinates, c) establishing a region D in the two-dimensional space of coordinates (A, B), d) establishing a discretization in the variables A, B of the region D, e) establishing a function f(A,B) the functional image of which is a positive integer value, f) establishing a region DO in the physical space of coordinates (x, y) corresponding to a surface area of the object, g) establishing a discretization in the variables x, y of the region DO, such that the number of discrete points m of the region DO is at least the sum of all the values f(A, B) for all (A, B) of the region D, h) providing a colour list according to the following sub-steps: h.1) establishing a colour with the value of the colour coordinates corresponding to the variables A and B by taking the value A and B, for each discretization point with coordinates (A, B) of the region D; and, repeated in the list as many times as indicated by the function f(A, B) the list making up a total of m elements h.2) assigning values to the rest of the coordinates (s 1, s 2,...,s n), different from A and B, in the m elements such that the colour is physically feasible, i) assigning the group of the m elements of the colour list to the m discretization points with coordinates (x, y) of the region DO, j) providing the object with the resulting image on the region DO of its surface. a) establishing a device independent colour coordinate system with variables (s 1, s 2,...,s n) n>=2 being the number of coordinates of said system with the variables (s 1, s 2,...,s n) defined in the physically feasible colour domain, b) establishing a pair of variables A, B from among the coordinates (s 1, s 2,...,s n) from the space of coordinates of a colour space, with A and B being different coordinates, c) establishing a region D in the two-dimensional space of coordinates (A, B), d) establishing a discretization in the variables A, B of the region D, e) establishing a function f(A,B) the functional image of which is a positive integer value, f) establishing a region DO in the physical space of coordinates (x, y) corresponding to a surface area of the object, g) establishing a discretization in the variables x, y of the region DO, such that the number of discrete points m of the region DO is at least the sum of all the values f(A, B) for all (A, B) of the region D, h) providing a colour list according to the following sub-steps: h.1) establishing a colour with the value of the colour coordinates corresponding to the variables A and B by taking the value A and B, for each discretization point with coordinates (A, B) of the region D; and, repeated in the list as many times as indicated by the function f(A, B) the list making up a total of m elements h.2) assigning values to the rest of the coordinates (s 1, s 2,...,s n), different from A and B, in the m elements such that the colour is physically feasible, h.1) establishing a colour with the value of the colour coordinates corresponding to the variables A and B by taking the value A and B, for each discretization point with coordinates (A, B) of the region D; and, repeated in the list as many times as indicated by the function f(A, B) the list making up a total of m elements h.2) assigning values to the rest of the coordinates (s 1, s 2,...,s n), different from A and B, in the m elements such that the colour is physically feasible, i) assigning the group of the m elements of the colour list to the m discretization points with coordinates (x, y) of the region DO, j) providing the object with the resulting image on the region DO of its surface.
