    At some point, these color and imaging attributes should be considered for
    adding to the PWG Semantic Model. So it would be good for the SM folks to
    participate in review of them.

    Also since the IPP WG doesn't meet face to face at the PWG meetings, the
    Semantics Model WG may pick up the slack. That is the strategy with the IPP
    "-actual" proposal.

    On the other hand, if the Semantic Model WG doesn't want to review the Color
    and Imaging Attributes specification, we could hold a teleconference to
    review the IPP extensions.

    Please indicate your preferences for reviewing this Color and Imaging
    Attributes specification.

    availab le

    I've down loaded a first draft for an IEEE-ISTO IPP Color and Imaging
    Attributes standard to the PWG FTP site. Most of the attributes control
    color and imaging that is prevalent in the industry following industry
    standards. The files are available at:

    There are several groups working on color and imaging attributes. The CIP4
    JDF specification already has most of these attributes. This specification
    gives a simpler subset of those color and imaging attribute for use in IPP,
    the PWG Semantic Model, the Free Software Group (FSG) Job Ticket API, PODi
    Job Ticketing Prioritization project (a subset of JDF Job Ticket suitable
    for "High Value Digital Print Systems"), and CIP4's Digital Printing WG
    effort for a Conformance Subset of JDF.

    Here is the Abstract:

    Abstract: This document specifies an extension to the Internet Printing
    Protocol/1.0 (IPP) [RFC2565, RFC2566] and IPP/1.1 [RFC2910, RFC2911]. This
    extension contains color and imaging attributes defined for submitting print
    jobs primarily to (but not limited to) production printers. The color Job
    Template attributes permit a user to control and/or override instructions in
    the document content to perform the following: control black overprinting,
    adjust color cast, lightness, saturation and contrast, specify source and
    destination color space translations, emulate the color output of other
    printers, control color image trapping, color rendering intent for text,
    graphics, or images, color depth, highlight color, and User defined Tone
    Reproduction Curves (TRCs). The imaging Job Template attributes control
    bleed edge printing, image aliasing, color effects mapping, page rotation,
    reference (large) images and control their fetching and cleanup, and control
    halftone screens. There is also a Printer Description attribute to indicate
    the colorants which are currently in use by the Printer.

    I've attempted to faithfully copy the format that Ron Bergman used for the
    PWG Media Name Standard, IEEE-ISTO 5101.1. I've also produced an MS-WORD
    template that follows the IEEE-ISTO format with guidelines to what goes in
    each section. I'll post this template in the next day or so. I've taken
    the liberty of numbering this document IEEE-ISTO 5100.8, as that is the next
    available number in the PWG IPP series and the level of interest in color
    and imaging attributes is high given the number of groups working on it.

    Please send comments to the IPP DL:
