I suggested further replies be sent to PWG reflector ONLY (not IPP). The
topic is broader then just IPP but I wanted to capture IPP participants
attention.
As for the topic... I think the point is that these characteristics DO
affect printing... that is the whole point. But surface characteristics
which affect printing can be achieved via more methods than just coating.
I don't think we intended to write a separate list of surface
characteristics which might be achieved by each method. So, our use of
"coating" is colloquial. I have no problem with that. If someone were to
interpret literally, they would be left wondering how to describe
something like "glossy-non-coated".

RE: PWG> Media Surface characteristics
Harry,
This appears to be a reasonable suggestion. The only potential "catch"
would be if the
presence of a coating, rather than the surface finish, affects the print
characteristics.
(I am not aware of a situation that falls into this category, but I also
don't have much
experience with technologies other than laser.)
If the coating does matter, then the MediaCoatingWKV is deficient in
providing that
information, since I suspect there is more information necessary than is
currently
defined to define the coating characteristics.

Subject: PWG> Media Surface characteristics
In the IPP Production Print Attributes - Set 1,
ftp://ftp.pwg.org/pub/pwg/candidates/cs-ippprodprint10-20010212-5100.3.pdf
Page 47, 3.13.10 we describe Job Template attributes which augment the IPP
media definitions including "media-front-coating" and
"media-back-coating".
These are likewise reflected in the PWG Semantic Model v1.0
MediaWellKnownValues.xsd as "MediaCoatingWKV".
</xsd:simpleType>
<xsd:simpleType name="MediaCoatingWKV">
<xsd:restriction base="xsd:NMTOKEN">
<xsd:maxLength value="255"/>
<xsd:enumeration value="none"/>
<xsd:enumeration value="glossy"/>
<xsd:enumeration value="high-gloss"/>
<xsd:enumeration value="semi-gloss"/>
<xsd:enumeration value="satin"/>
<xsd:enumeration value="matte"/>
</xsd:restriction>
</xsd:simpleType>
Three questions to be considered
1. In use, it seems what we really wanted to convey is "surface
characteristics". By labeling the element "coating" and including the
value "none", there is an implication that coating is necessary and it
leaves NO WAY to represent surface characteristics of a NON-COATED media.
For example, in paper, it is possible to achieve a high gloss via high
pressure calendaring (no coating... but results in shiny surface". IS IT
ACCEPTED PROPER INTERPRETATION TO USE MediaCoatingWKV to mean media
surface characteristics, in general, coated or not?
2. If the answer to 1 is YES, then what is the semantic of the value NONE?
3. What is the accurate and preferred way to reference this "dictionary"
in another document. Is it more proper to reference 5100.3-2001(The IPP
extension which originally documented these values) or 5105.1 the Semantic
Model, or point directly to MediaWellKnownValues.xsd? I assume SM is
preferred.
Sorry for the double post. I think this is broader than just an IPP
question but the root document is an IPP extension.
