Abstract: A lightweight digital printing medium has a basis weight of less than 100 grams per square meter and includes a base paper. The base paper includes a fiber mixture of hardwood pulp and softwood pulp where at least 5% by weight of total fiber in the fiber mixture is bleached, chemi-thermo-mechanical pulp. An internal sizing agent for neutral or alkaline conditions and a wet-strength agent that is a thermosetting resin are mixed with the fiber mixture. An amount of the wet-strength agent added to the fiber mixture is at least 0.1% total dry weight of the base paper.
