My reason for bring up this issue was due to the absence of highlight color for images.
When I discussed this with Peter, his view is that an image, other than full color, does
not have a colorant associated until it is processed by the printer.  To be consistent 
with this assumption, the term "black" should be replaced with "monochrome".  An
inconsistent solution would be to add highlightImages to the counters spec.

Harry,

 

I do not agree that the argument for using  "black"  for images is the same as using "black" for impressions. For example, you are not interested in colorant usage in image counters; indeed there is no inherent reason to believe that the image will ever be printed. But quite frankly, I don't feel that strongly one way or the other. Ron, how critically do you take this issue?

 

We do have significantly more far reaching issues that this. If we are dropping the counter MIB because we believe all counters should be fully defined in the counter spec, then I suggest we will have the same problem mapping to a schema. Without being able to map to a form that can be communicated as useful parameters, the  counter spec becomes useless.

Thanks, Ira. 

I was aware of the inconsistency (but not all the specific references). I think it is a result of a rather sloppy (on our part) mapping of marketing and technical terms into our standards and semantics. This shows the value of, now, having a common semantic model where definitions from parallel work groups must be reconciled (we didn't have this in the past). Throughout the past 20 years, it has been common in the MARKET PLACE to distinguish between "monochrome" and the emerging "color" market in printers. Monochrome (in my opinion) was basically a technical term used by marketing as a more concise (and "sexy") way to describe what the average public would otherwise refer to as "black and white". 

Of course, PWG members understand the term both technically and in it's market use. In the past, we got away with assuming our spec reader could also be as ambidextrous in their use of the terms. 

When we came to the Counter Spec, where we are actually wanting to measure the use of black colorant in exclusion of any other mixtures, I think we were right to choose the term BLACK as it is more explicit than monochrome.

Hi Harry,

The Job Mon MIB (of which you are a co-editor) uses
the term monochrome once in the (badly written)
definition of 'Impressions'.

Later in HighlightColorImpressions, it uses the term
black (to describe the black colorant).  There, it
does not refer to monochrome.

The Printer MIB uses the term monochrome once to say
"process color of 1 implies monochrome".

The Printer MIB uses the term black once to refer to
the colorant in prtMarkerColorantValue.


Cheers,
- Ira

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.
