The reasoning for using the term Black (vs Monochrome) sure seems 
identical in either case (Images or Impressions)... just that Images are 
scanned and Impressions are "deposited". If we have used both terms in 
past, normative definitions, I guess we'll have to live with them. If not, 
we should think seriously about converging on "Black" and making sure we 
embellish any explanations where needed.

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.
