Harry,

 

I agree with your comments, and would argue that "Black" impressions is
preferable to "Monochrome" impressions. However, Ron did not refer to
impressions but rather to images. So this is not a question about what is
actually deposited on media, but what is defined in a job. If no color is
defined, then the image may be considered monochrome. A job where a cyan
image is defined would be treated as full color, even if it were the only
color.  If this is Ron's reasoning, I think it makes sense. The question
then is if the use of "black" with impressions and "monochrome" with images
adds to understanding or to confusion.

As background... we discussed Black vs Mono at the Tokyo f2f. There is an
intuitive question of whether we are really trying to count BLACK (only)
pages vs Full Color or Spot Color pages or whether we are using Black as a
synonym for Monochrome vs Full Color. The result would be nearly the same
except that with the later one could ask how to count a completely Cyan
(unlikely) page, for example. In Tokyo we concluded that, indeed, we are
counting BLACK (only) pages. Aside from being inherently monochrome, Black
has a unique role in printing as many printers have various contone
components (of which Black is one) and spot colors but Black (only)
impressions may be accomplished without engaging the contone features or
pathway in some cases. Also, Monochrome and Black really ARE synonymous,
Black being so much so the majority of monochrome that other cases (Cyan
only, Magenta only) become pathological. 

I know another thread ensued abut where and what documents already carry
these definitions but I wanted to share this "common sense" dialog which
occurred in Tokyo at the Last Call review also, prior to the next WIMS
teleconference.
