Matrix Print Data Storage and Method for Encoding the Data
First Claim
1. Object such as, in particular, paper having applied thereon a matrix print for the storage of encoded data of high data density, the printed surface of the object being sub-divided into mutually adjoining matrix cells of pre-designed configuration composed of matrix points, and in each matrix cell at least two different patterns R, I, . . . being imprinted, characterised in that each of the patterns R, I, . . .i) is selected from pair-wise isohedric, non-overlapping patterns (Ro, R1) respectively (Io, I1),ii) borders by way of at least one matrix point onto another pattern of the same matrix cell andiii) occupies different matrix points in the matrix cell.

Abstract
The invention relates to an item, particularly such as paper, with applied matrix printing, for the storage of encoded data with high data density, whereby the printed surface of the item is divided into matrix cells, comprising matrix points with a given form and at least two different forms R, I, are printed in each matrix cell. Each form R, I, is selected from pairs of non-overlapping forms (R0, R1) or (I0, I1), having the same area adjacent to at least one matrix point of another form in the same matrix cell and occupying various matrix points in the matrix cell.
