Abstract
A proofing substrate includes a proofing sheet layer of a lightweight paper and a carriage layer of a heavier weight paper attached to the proofing sheet. The proofing sheet can be yellow page stock that is used to print “yellow pages” portions of telephone directories. The proofing can alternatively be newsprint paper. The weights of the first and second layers are selected based on an aggregate weight of the two sheets. The carriage layer has a weight selected so that it can feed the proofing substrate through a desktop printer or copier. The proofing substrate has at least one adhesive layer to hold the carriage and the proofing sheet together.
