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. ---------------------------------------------- Harry Lewis IBM STSM Chairman - IEEE-ISTO Printer Working Group http://www.pwg.org IBM Printing Systems http://www.ibm.com/printers 303-924-5337 ---------------------------------------------- <table width=100%> <tr valign=top> <td width=40%>"McDonald, Ira" <imcdonald@sharplabs.com> 04/25/2005 01:24 PM <td width=59%> <table width=100%> <tr valign=top> <td> <div align=right>To</div> <td>Harry Lewis/Boulder/IBM@IBMUS, William A Wagner <wamwagner@comcast.net> <tr valign=top> <td> <div align=right>cc</div> <td>wims@pwg.org <tr valign=top> <td> <div align=right>Subject</div> <td>RE: WIMS> Black vs Mono</table> <table> <tr valign=top> <td> <td></table> </table> <tt>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.

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 Lewis IBM STSM Chairman - IEEE-ISTO Printer Working Group http://www.pwg.org IBM Printing Systems http://www.ibm.com/printers 303-924-5337 ---------------------------------------------- "William A Wagner" <wamwagner@comcast.net> 04/25/2005 10:12 AM ToHarry Lewis/Boulder/IBM@IBMUS cc<wims@pwg.org> SubjectRE: WIMS> Black vs Mono 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.   Bill Wagner   -----Original Message----- From: owner-wims@pwg.org [mailto:owner-wims@pwg.org] On Behalf Of Harry Lewis Sent: Monday, April 25, 2005 10:21 AM To: William A Wagner Cc: wims@pwg.org Subject: WIMS> Black vs Mono   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. ---------------------------------------------- Harry Lewis IBM STSM Chairman - IEEE-ISTO Printer Working Group http://www.pwg.org IBM Printing Systems http://www.ibm.com/printers 303-924-5337 ---------------------------------------------- </tt>
