carbon/carbro is

though this may be important with half-tone separations.

Well, there are at least two of us who don't understand.

Luis, could you perhaps explain what you mean in the paragraph above.
I don't understand your last sentence.In my opinion 4-color
separations are not necessary in most cases with color carbon and carbro
processes. Also, one of the huge
differnces I have noticed in comparing 4-color prints (both EverColor
and Ultra-Stable) with conventional carbon and carbro prints is that
the former lack the dimensional quality (from relief) of the latter. As
memory recalls you predicted this in some of your earlier writings, or
do I confuse myself?
