Abstract
The present invention relates to a method of classifying print substrates for printing, to a print process, a method of estimating the print properties of print substrates and a novel use of ink requirement. In the method, a parameter describing the structure of the print substrate is measured and one of a number of print substrate classes is selected for the print substrate at least partly on the basis of the measured structure-describing parameter. According to the invention the parameter describing the structure is ink requirement, which has been found to well describe dot gain. The invention produces an efficient way of classifying paper on the basis of its colour reproduction properties.
