Hi Karl.
But, on the other hand, using different black generation policies for images
on a single signature may have the *positive* effect of preserving the
integrity of images in that signature that we want to *protect* against
possible color shifts on press, while allowing other less critical ones to
shift as they may.
For example, if you have some images on an individual signature that are in
full color and others that also use all 4 inks but are meant to look
neutral, you may want to separate the latter using a stronger black
generation (not "Max K" necessarily) to provide added protection against
loss of neutrality, whereas the former can still be separated with a lower
black component.
