The definition of "perfect" being good enough that no human could tell
the difference.

there are a lot of humans who can tell the difference between a canned
profile and a properly made profile for the printer/ink/paper combo you
are actually using.

however, the difference is usually minor and most people don't care.

It is not a case of "most people don't care" that makes
the difference. What makes a difference is the job.

If you, for example, get a contract with Nikon to
generate an advertisement, which makes more than minimal
use of the color yellow... it won't make a difference
to anyone of the poster stapled to a telephone pole down
the rode from your home is even close to the same color
yellow as is seen in the poster stapled to an alley wall
on the other side of town. Clearly if the two posters
are printed on different machines, using different paper
and different inks, all will be fine even if stock
profiles are used.

Now consider putting an insert into a magazine, between
two pages that also have Nikon's yellow. Two different
types of paper, maybe two different printers and sets of
ink. And stock profiles would probably produce a
product that almost everyone would see as two different
colors of yellow... because they are both right there
next to each other! And Nikon will reject your work,
not pay you, and never talk to you again.

those are not a 'most people' scenario.

You do see where I pointedly said that is NOT the
scenario that matters... Of course what does matter is
therefore a case of "those are not a 'most people'
scenario."

Think before you blabber so much.

i have been.

perhaps you ought to try it.

the reality is that most people do not care about accurate colour. they
were happy with 1-hour photo-processing and they're happy with whatever
they get from a printer, even *without* any colour management at all,
as long as it's reasonably close.

But the fact is that most people do care. That is why a
company like Nikon is very very careful about having the
yellow exactly the same on two page spread in a
magazine. Not close, not most of the time, but exact the
same every time.

*nikon* might care because it's their ad.

Signature colors are considered to be IP these days. Nikon might be
concerned about threespassing on let's say Cat's yellow...

If it isn't, people will notice and people will react
negatively.

no they won't. they'll just think it's a bad print run and move on.

to put it another way, grandma isn't going to complain that her
granddaughter susie's dress is not the exact shade of blue it's
supposed to be or if her skin is a bit too yellow. it simply doesn't
matter.

Because she can't compare them. It isn't that she just
doesn't care.

sure she can compare them. the grandkid is right next to her wearing
the very same blue dress she bought for her.

most people are happy if the photo is in focus. they're really not all
that fussy.

photogeeks are fussy, but they're the minority.
