Abstract
Abstract A device for indicating a quantitative change in dot area of an image in a printing process and the method of making the same. The apparatus includes a square matrix array on a substrate. Four square members are provided in the matrix array on the substrate. The square members are each equal in size and have certain of their corners in juxtaposition with certain corners from other square members to form a square center opening bounded by a side from each square member. The device also includes five circular shaped members, provided in the matrix array on the substrate. The circular members are each equal in size. One of the circular members is positioned in centered, spaced relation in the center opening and the other of the circular members are each positioned in adjacent and centered, spaced relation to a pair of adjacent sides provided by the juxtaposition of the corners of the square members, with one side of the pair of adjacent sides being provided by one square member and the other side of the pair of adjacent sides being provided by another square member. The circular members are each spaced a preselected distance from an adjacent side of an adjacent square member to form a gap therebetween so that an increase in area of the squares and the circular member to the extent that the periphery of the shaped member is in juxtaposition with the sides of the squares is indicative of a predetermined change in dot area.
