I'm reading from pages 504-505 of the 2nd Ed of RWCM. Is the example of that
Dahlia representative of the kinds of high-end optimizations, after-the-fact
conversions to CMYK, you have in mind?
In the example you gave, you went from C0 M88 Y89 K0 to C0 M93 Y95 K2,
effectively increasing the red saturation while decreasing its lightness
somewhat. Yes, those are 'routine', subjective optimizations a trained
scanner operator is going to make because of experience, judgement and a
number of other things. But I'm not convinced that increasing the chroma by
1 unit, in this case, at least, is going to all that much difference on
press. You see, if I had to choose between accepting what an 'automated'
conversion the best output profiling packages gave me and the 1 extra chroma
unit gained by adding 5 magenta and 6 yellow, gained at the expense of extra
processing time, I think I would choose to leave the color as is. Don't get
me wrong, standards are as high as yours -- everybody wants nice colors.
And, yes, I agree it makes sense (businesswise and estheticwise) to pursue
this kind of repro excellence, and in many, many high-end imagery such as
for cosmetics, cars, gems, and what have you, I think those extra pampering
steps are warranted and welcome.
Come to think of it, the results of the above example looks a lot like the
difference between ProfileMakerPro v5+ and MonacoProfiler v4.7+...
