CTP (computer to plate) plus digital proofs provides a finer resolution and added color control, through the use of ICC Color profiling and state of the art digital proofing which provides a very close color match to the actual piece. Downsides of CTP + digital proofs are reduced recognition of spot color and color overprint issues, color shifts or show-through due to the choice of paper or other substrate. It also is associated with a more expensive overall procedure, and will have an effect on the project cost. We recommend CTP for coffee table books or projects requiring exact color matching and super-fine resolution.
CTF (computer to film) plus wet proofs offer the opportunity to see how your piece will look in real printing ink on the real paper selected for your project. You can easily evaluate spot color effects and overprint areas, test paper opacity and sensual results. Wet proofs are the closest possible match to the final piece in terms of material effect. Downsides of CTF + wet proofs are an inability to implement ICC Color profiling and a need to disregard minor proofing flaws such as slightly loose registration or heavy density due to the nature of the proofing process. We recommend CTF for most projects we execute.
