I see what you mean. Yes, the blockiness comes from the image having a very
wide gamut in the reds, much wider than can be represented on the screen.
Even just turning down the saturation with Hue/Saturation brings back the
detail. The detail is lost regardless of which CMM I use (Adobe or
Microsoft) or what I set the rendering intent to, which belies the myth that
the rendering intent successfully compresses the gamut to prevent the loss
of detail.
It's possible that some printer may have a wider red gamut than the screen,
and could represent the detail without desaturation, but my limited
experience is that inkjets don't excel in that area. However, what I
suggested in my previous post, using Hue/Saturation and selecting just the
red colors to desaturate, seems to work very well, without degrading the
greens.
