Hi, Wednesday (1 June 2005)
Below are some definitions for addition to section 2.2 of the PWG
Imaging System Counters spec, per our review at today's WIMS telecon.
Cheers,
- Ira

[delete the following incorrect definitions from section 2.2]
Blank, Full Color, Highlight Color, and Monochrome
------------------------------------------------------------------------
[boldface the the following term in its definition in section 2.2]
Work
------------------------------------------------------------------------
[add the following source for definition of Message to section 2.2]
Source: This document defines Message consistently with the OSI Basic
Reference Model [ISO7498-1].
[and add the following to Informative References]
[ISO7498-1] Information technology -- Open Systems Interconnection --
Basic Reference Model -- Part 1: The Basic Model, ISO 7498-1:1994.
------------------------------------------------------------------------
[revise the following definition in section 2.2]
change:
Impression: An Impression is the image imposed
^^^^^
to:
Impression: An Impression is the content imposed
^^^^^^^
[the term 'image' came from the IPP/1.1 definition, but it's circular,
as Bill Wagner has observed - the term 'content' preserves the meaning.]
------------------------------------------------------------------------
[add the following definitions to section 2.2]
Blank Image: A Blank Image is an Image requiring zero pixel colors to
represent.
Source: This document originates this definition of Blank Image by
analogy to Blank Impression.
Blank Impression: A Blank Impression is an Impression requiring zero
colorants (i.e., no marks are impressed on the media sheet side by the
processing Service). Pre-printed media do not affect Blank Impression
counters (i.e., it is the lack of any content marked by the processing
Service that distinguishes a Blank Impression).
Source: The document originates this definition of Blank Impression as
an extension of the other impression types.
Blank Sheet: A Blank Sheet is a Sheet with no Impression marked on
either side.
Source: This document originates this definition of Blank Sheet by
analogy to Blank Impression.
Full Color Image: A Full Color Image is typically defined as an Image
requiring three or more pixel colors to represent, but this MAY vary by
implementation.
Source: This document originates this definition of Full Color Image by
analogy to Full Color Impression.
Full Color Impression: A Full Color Impression is typically defined as
an Impression requiring three or more colorants, but this MAY vary by
implementation. In any case, the value of a Full Color Impression
counter MUST increment by one for each media sheet side that is marked
in full color, not by the number of colorants used.
Full color takes precedence over monochrome or highlight color on a
given media sheet side (i.e., the most complex process MUST be counted).
Source: This document imports this definition of Full Color Impression
from the Job Monitoring MIB [RFC2707].
Full Color Sheet: A Full Color Sheet is a Sheet with a Full Color
Impression marked on one or both sides.
Source: This document originates this definition of Full Color Sheet
by analogy to Full Color Impression.
Highlight Color Impression: A Highlight Color Impression is typically
defined an Impression requiring a black colorant plus one other
colorant, but this MAY vary by implementation. In any case,
a Highlight Color Impression counter MUST increment by one for
each media sheet side that is marked in highlight color.
Full color takes precedence over monochrome or highlight color on a
given media sheet side (i.e., the most complex process MUST be counted).
Source: This document imports this definition of Highlight Color
Impression from the Job Monitoring MIB [RFC2707].
Highlight Color Sheet: A Highlight Color Sheet is a Sheet with a
Highlight Color Impression (but not full color) marked on one or both
sides.
Source: This document originates this definition of Highlight Color
Sheet by analogy to Highlight Color Impression.
Monochrome Image: A Monochrome Image is an Image requiring a single
pixel color (typically black, but this MAY vary by implementation).
Source: This document originates this definition of Monochrome Image by
analogy to Monochrome Impression.
Monochrome Impression: A Monochrome Impression is an Impression
requiring a single colorant (typically black, but this MAY vary by
implementation). In any case, a Monochrome Impression counter MUST
increment by one for each media sheet side that is marked in monochrome.
Full color takes precedence over monochrome or highlight color on a
given media sheet side (i.e., the most complex process MUST be counted).
Source: This document imports this definition of Monochrome Impression
from the Job Monitoring MIB [RFC2707].
Monochrome Sheet: A Monochrome Sheet is a Sheet with a Monochrome
Impression (but not full color or highlight) marked on one or both
sides.
Source: This document originates this definition of Monochrome Sheet
by analogy to Monochrome Impression.
Media Sheet: Synonym for Sheet (see definition of Sheet below).
Source: See definition of Sheet below.
