Soft proofs are digital proofs that simulate accurately how the finished publication will look, intended to highlight any future issues.The imposition proof, which is usually done by the printers, should also be printed out to check and adjust the printing press. The printer's proof should be printed out in high resolution and checked by the customer. Print-ready PDF files should be made after the layout using preflight at the printing house. In this part, three types of proofing should be checked and printed out: the print-ready PDF files, the printer's proof and the imposition proof.

Proofs in general can be done for all parts (images, illustrations, text and colors) of the print product. This serves as a bond between the printer and their customer that the final product meets an agreed-upon standard. Proofing involves creating an accurate copy of the artwork before beginning production runs.
