At Professional Imagemaker, the cover is always proofed for reference
Proofing
One of the reasons that RIPs are so expensive is because they have to cover so many possibilities and permutations. Thus the Fiery RIP includes facilities for around 128 different printers and for each of these there may be 10 or more media types - and this is just the input side! On the output side all the common printing press situations have to be simulated, adding another level of complexity.
To be a contract proof the print must have the data label stuck firmly to it, without a label it is invalid.
Verification
It is the verification process which provides security to a commercial photographer who passes their work onwards to an outside service provider. There are a number of flavours to this process but we will concentrate on one of the most popular in Europe, the Fogra V3 patch set and standard. This has to be printed and then measured to a set of defined tolerances before a proof can be classified as a contract proof.
The standard is high and almost certainly unobtainable from a non-RIP workflow, especially in the dark tones. This is not even to say that the non-RIP workflow off a quality modern printer is inferior, sometimes it is too good and represents a quality that a printing press cannot achieve but is not therefore a representative output for a press. Typically this will show in the darker tones of an image, non-RIP RGB workflows almost always fail on the dark colours because they are rendered too dense ie they are richer in shadow detail, but not representative!
