Security band, has points printed by impression on space, and symbol defined to predict that points of plot are distributed geometrically and dimensionally, where space between points simulates continuous bottom

摘要

The band (1) has sectors having a discontinuous bottom, where the discontinuous bottom consists of a plot of points (2) that are printed by impression on a space (3). A symbol (4) is defined to predict that the points of the plot are distributed geometrically and dimensionally. The space between the points simulates a continuous bottom.
