ABSTRACT:

BACKGROUND
This invention relates to printing proofs on paper.
Printed materials such as newspapers and telephone directories are printed on lightweight paper. These printed materials often include advertising particularly with graphics. Usually proofs of an advertisement are produced before printing of the final product. These proofs are printed on conventional 50 lb. weight paper from a file that contains a bitmap or other type of digitized representation of the advertising graphics. The proofs are sent to the customer for approval. There may be some rework after the customer examines the proof. After customer approval or acquiesce of the customer, the file that was used to produce the proof or a reworked version of the file is used to print the finished product. When the product is printed there may be some problems in which a customer may seek monetary adjustment.
SUMMARY
According to an aspect of the present invention, 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 proofing sheet can have a weight in a range of about 20 lbs. to 35 lbs, preferably in a range of about 22.5 lbs. to 30 lbs. The color of the paper is selected based on the application of the proofing sheet layer. The carriage layer can have a weight in a range of about 40 lbs to 60 lbs. 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.
According to an additional aspect of the invention, a method of producing proofs of an image for paper printing applications includes printing an image on a proofing sheet portion of a proof substrate.
One or more of the following advantages may be provided by aspects of the invention. The proofing substrate is comprised of two layers, a proofing sheet layer and a carriage layer. Artwork is printed on the proofing sheet, while the carriage layer is used to guide the proofing substrate and in particular the proofing sheet through a printing process. Thus, rather than using conventional photocopy paper to print a proof, the proof is printed on the proofing substrate and in particular the proofing sheet. The proofing sheet can be removed from the proofing substrate leaving the finished proof. The proof is now on the same weight page stock that is used to print the finished product.
The finished proof can be sent to the customer for approval. At this point, however, there is an example of the advertisement as it would appear in a printed book, and it is less likely that there would be any cause to make an adjustment for a dissatisfied customer. Therefore, causes for dissatisfaction can be caught earlier in the process. Moreover, even prior to the stage of initial customer approval, the facility could make adjustments because they may find problems with the proof that would not appear on the conventional proof. Thus, there is opportunity for savings at initial customer approval and post print customer approval stages.
