Abstract

A method for determining a perforation matrix includes selecting a trial value for a number of matrix increments across a length and a width of a first major surface of a substrate, selecting a trial value for a number of rows and columns in the matrix, calculating a row spacing value and a column spacing value, comparing the calculated row spacing and column spacing to the target row spacing value and the target column spacing value in the matrix to determine if the values are within a predetermined tolerance of the target row spacing value and target column spacing value, if the values are not within the predetermined tolerance of the target spacing values, repeating, and, upon calculating values within the predetermined tolerance, selecting the lower of the row spacing value and the column spacing value as the final matrix spacing value of the perforation matrix.
