<h2 id="howto">How to read this document and give feedback</h2>
<p>This draft of SVG Print is a snapshot of a work-in-progress.</p>
<p>The main purpose of this document is to encourage public
feedback. The best way to give feedback is by sending an email to
<a href=
"mailto:public-svg-print@w3.org">public-svg-print@w3.org</a>.
Please identify in the subject line of your message the part of the
specificationto which your comment refers (e.g "Print compositing"
or "Print render formats"). If you have comments on multiple areas
of this document, then it is preferable to send several separate
comments.</p>
<p>The public are welcome to comment on any aspect in this
document, but there are a few areas in which the SVG Working Group
are explicitly requesting feedback. These areas are noted in place
within this document. There is also a specific area related to the
specification that is listed here:</p>
<p class="note">Interaction with other print standards. The SVG
Working Group believe that some design decisions would be best made
in collaboration with other print standards bodies, and would
welcome liaison statements in this area.</p>

<h2 id="introduction">1 Introduction</h2>
<p>This document lists features that may be used in the context of
printing. The various usage scenarios are listed in the SVG Print
Requirements document.</p>
<p>This document is normative.</p>
<p>This document contains explicit conformance criteria that
overlap with some RNG definitions in requirements. If there is any
conflict between the two, the explicit conformance criteria are the
definitive reference.</p>
<p>This document contains conformance criteria for a number of
different entities:</p>
<ul>
<li>The Content (ie. conformance criteria on the document
author).</li>
<li>A User Agent for Printing.</li>
<li>A User Agent for Print Preview.</li>
</ul>
<p>Some conformance criteria allow or require the User Agent for
Printing and the User Agent for Print Preview to communicate with
each other.</p>
<p class="note">The conformance criteria have awkward names - any
suggestions for replacing "A User Agent for Printing", "A User
Agent for Print Preview", and "A User Agent for Printing or Print
Preview" would be welcome.</p>
<div class="note">
<p>TODO: The above terms will probably be replaced as follows:</p>
<dl>
<dd>SVG Print Preview Device ---> Print Preview Agent (PPA)</dd>
<dd>SVG Printing Device ---> Print Reproduction Agent (PRA)</dd>
<dd>SVG Printing or Print Preview Device ---> Print User Agent
(PUA)</dd>

<p>Note that by default, color <em>interpolation</em> occurs in the

provided, unless the <a href=

"prop-name">'color-interpolation'</span></a> property is set to one
of the CIE Lab color spaces. If an sRGB color interpolation space
is specified, all ICC-based colors used for the interpolation must
be converted into the sRGB interpolation colorspace.</p>
<h4 id="sRGBcolor">5.2.1 sRGB colors</h4>
<p>As with SVG Tiny 1.2, colors may be specified in the sRGB color
space (see <a href="http://www.iec.ch/nr1899.htm">[sRGB]</a>).
Since all SVG Print and SVG Print Preview User Agents are color
management capable, the rendering requirements are more strict than
for SVG User Agents [SVG11] where color management is optional.</p>
<div class="requirement" id="assert_sRGB">
<p>When an sRGB color is used - because it is the sole color
specification, or in a permitted fallback situation - a conformant
SVG Print or SVG Print Preview User Agent shall render it in

</div>
<h4 id="icc-colors">5.2.2 ICC colors</h4>
<p>As with SVG Full 1.1, SVG Print content may specify color using
an ICC profile (see [<a href="#ref-ICC42">ICC42</a>]). For
resiliency and for compatibility with SVG Tiny 1.2, an sRGB
fallback must still be provided.</p>
<div class="requirement" id="assert_ICCColorPrecedence">

<p>SVG Print introduces the ability to specify a color using a
'Named Color Profile'.</p>
<div class="requirement" id="assert_ICCNamedColorPrecedence">

</div>
<h4 id="device">5.2.4 Uncalibrated device colors</h4>
<p>SVG Print also introduces a method of specifying uncallibrated
device colors. This is sometimes useful in print workflows. This
feature utilises the <a href="#deviceColor-elem"><span class=
"element">deviceColor</span></a> element and the <a href=
"http://www.w3.org/TR/SVGMobile12/painting.html#SpecifyingPaint">device-color</a> keyword.</p>
<p>As these are uncalibrated, any interpolation or compositing
occurs using the fallback sRGB color space</p>
<p class="note">TODO: Need feedback on this feature. Looking into
the possibility of having ICC or Name ICC fallback for Device Color
as well. ICC or Named ICC should have priority over an sRGB
fallback if both types of fallback are specified.</p>
<h3 id="ColorProfileDescriptions">5.3 Color profile
descriptions</h3>
<h4 id="ColorProfileDescriptionsOverview">5.3.1 Overview of color
profile descriptions</h4>
<p>The <a href="http://www.color.org/">International Color
Consortium</a> has established a standard, the ICC Profile
[<a href="http://www.color.org/ICC-1A_1999-04.PDF">ICC32</a>], for
documenting the color characteristics of input and output devices.
Using these profiles, it is possible to build a transform and
correct visual data for viewing on different devices.</p>
<p>A <span class="SVG-Term">color profile description</span>
provides the bridge between an ICC profile and references to that
ICC profile within SVG content. The color profile description is
added to the user agent's list of known color profiles and then
used to select the relevant profile. The color profile description
contains descriptors for the location of the color profile on the
Web, a name to reference the profile and information about
rendering intent.</p>
<h4 id="ColorProfileAlternatives">5.3.2 Alternative ways for
defining a color profile description</h4>
<p>Color profile descriptions can be specified in either of the
following ways:</p>
<ul>
<li>a <a href="#ColorProfileElement"><span class=
"element-name">'color-profile'</span></a> element</li>
<li>an <em>@color-profile</em> rule within a CSS style sheet (only
applicable for user agents which support using CSS [<a href=
"http://www.w3.org/TR/REC-CSS2/">CSS2</a>] to style the SVG
content)</li>
</ul>
<div class="requirement" id="assert_colorProfileCSSBeforeElement">

identified by both a <a href="#ColorProfileElement"><span class=

<em>@color-profile</em> rules within a CSS style sheet, then the
user agent MUST first attempt to locate the profile by using the
specifications in the <em>@color-profile</em> rules first.</p>

<h4 id="ColorProfileAtRule">5.3.4 <strong>@color-profile</strong>

<p>When the document is styled using CSS, the

profile description. The general form is:</p>

@color-profile { <color-profile-description> }

given explicit values in the rule take the initial value listed
with each descriptor in this specification. These descriptors apply
solely within the context of the @color-profile rule in which they
are defined, and do not apply to document language elements. Thus,
there is no notion of which elements the descriptors apply to, or

<h3 id="deviceColor-elem">5.4 deviceColor Element</h3>
<p>Certain print applications can improve printing quality by
specifying colors by name or in an alternative color format. This
is commonly referred to as using 'spot' colors, device colors or
inks, and usually means that a particular ink will be used for the
color when it is printed. Furthermore, there are applications in
the printing press industry where presses can be set up with
different inks for different jobs. This means that the content
creator will need to create content tailored to the particular
press setup in order to obtain the best results.</p>
<p>The <span class="element">deviceColor</span> element can be used
to indicate an alternative color for a particular paint. This
element will be mostly used in closed workflows, since the names of

This example <span class="attribute">value</span> attribute
provides the definitions of colors or inks to be interpreted in the
context of the URI specified. It is in a private namespace so that
content and context authors can use any understood format to convey
the necessary information. When the particular <span class=
"element">deviceColor</span> element is referenced later by a
<span class="property">device-color</span> keyword specification,
it is generally expected that the number of parameters following
the name reference (1st parameter) in the function-like
representation for the value of <span class=
"property">device-color</span> alternate in a fill or stroke
attribute (for example) will have an understood one-to-one
correspondence with the information specified for the value
attribute in the the <span class="element">deviceColor</span>
element. The interpretation of the parameters is implied
specifically by the context set by the URI.</p>
