In fact, except for some special high-end cases, this is the way to go.
Although "Adobe Sheetfed Coated v2" is probably not a good choice (given the
unknown origin), and a GraCol profile would be better (for sheetfed).
And the terms "generic" or "canned" usually carry a "low quality"
connotation, but let me remind you that some good things come in cans too.
That "generic" can be a very high-quality construct.
A press can be manipulated more than anything else. It can be manipulated to
match a proof, as long as the proof is a realistic representation of offset
printing with inks and paper conforming to some standards (as most are).
If everyone were to go the "I profile my press" route, a customer would
never be able to print the same job accurately in different parts of the
country. Can you imagine Sports Illustrated being printed in several places
around the US, and everyone of them having it's own "press profile"?
What they do is establish a "standard press profile", be it one developed
internally (from averages, from a reference site, whatever), and then make
the proofs to that profile. And then make the presses all over the world (or
at least the country) that print for them, match those proofs. Exactly like
the situation you describe, except for the fact that they probably don't use
"Adobe Sheetfed Coated v2".
Profiling an individual press falls in four levels of "desirability":
- nonsense: it's nonsense to profile an individual press when it's not
particularly high-quality, when it's not tightly controlled (some printers
don't even use densitometers), when they change consumables brands every
month chasing price or availability.
- unnecessary: it's not necessary to profile an individual press when that
printer vows to adhere to a certain printing standard, such as ISO or GraCol
or SWOP. In that case, using the "canned" (in fact "standardized" is a
better word) profile for the standard should be enough, in fact even better,
than using individual press data. You can build your own profile from the
standardized data, if you want your particular flavour of max ink and black
generation.
- good idea: if you are willing to deviate from the 'standards' because you
can achieve a better quality by doing so, if you want a really perfect match
proof-to-press and have very tight press controls.
- necessary: if you print with techniques, consumables or practices that
differ from the standards; for example if you use special screening (such as
stochastic, hybrid, etc), if you use your own set of densities, if you use
special inks (high pigment, etc), if you use a special platemaking
technique, etc.
My 2 cents.
