Subject: PDF: Is this going to be a problem in the future?
Just got this e-mail off of the PDF listserv. I'm not sure what the
full ramifications are...but I'm still a little worried that it is
now March and are friends at Adobe still have not released their
PDF/Acrobat beta code for print disability access....

PDF FORMAT CHOSEN FOR GRAPHIC ARTS EXCHANGE
The Committee for Graphic Arts Technologies Standards (CGATS) has announced
that Subcommittee 6 of CGATS has selected Adobe System's Portable Document
Format (PDF) as a basis for a standard to address the industry requirement for
digital distribution of printing data.
CGATS formed SC6 in response to a need to develop standards to permit
transmission of digital ad data electronically.
According to Gerd Koehler, Chairman of SC6: "The Digital Distribution of
Advertising for Publications (DDAP) Association has been lobbying for the use
of industry standards to allow digital ad distribution for some time. SC6, in
response to this need, is developing standards that will allow for digital ad
distribution as well as facilitate digital data exchange of composite page
data for other print applications."
SC6 is finalizing the user technical requirements to summarize the needs of
the industry. Based on these requirements, two standards will be written.
One will focus on the exchange of raster data based on the work of IT8 and ISO
TC 130. TIFF/IT-P1 (ANSI IT8.8-1993 and ISO 12639) will be the basis for this
work which will allow the exchange of rendered pages targeted to a variety of
printing processes in a transport-independent format.
The challenge of transferring a combination of object-oriented data and
raster data concurrently has been more difficult to resolve. The solution
will be a second standard, titled "Graphic technology exchange of digital page
data in final form using PDF". The standard will detail a transport
independent exchange mechanism based on Adobe's PDF data exchange format. The
PDF format is open-ended and allows TIFF/IT-P1 raster data objects to be
packaged within a PDF file and linked to PDF objects.
Application software that accepts PDF, such as Adobe Acrobat, could view the
TIFF/IT-P1 information with an appropriate TIFF/IT viewing plug-in.
Steve Zilles, Manager of Standards for Adobe Systems, said: "Adobe is
delighted that SC6 has chosen this path forward. PDF was developed to meet
the needs of many industries transferring, in a device-independent form, data
targeted for rendering on a variety of different rendering engines from
personal computer screens to printing presses. We are working closely with
SC6 to define a process that fits this specialized application."
PDF is a file format used to represent a document in a manner independent of
the application software, hardware and operating system used to create it.
PDF, the Portable Document Format, has been published as a publicly available
specification by Adobe Systems.
Some of the key elements to be included in this CGATS standard:
#007# Fonts will be included with the PDF to assure rendering with the
exact
same font and font metrics.
#007# Raster data will be accommodated by incorporating or calling external
files, including TIFF/IT-P1.
#007# Data to be exchanged will include single colors or CMYK process
colors
with colorimetric characterization data to assure correct color
rendering.
The initial requirements for these standards are based on The Digital
Distribution of Advertising for Publications (DDAP) User Requirement
Specification - Version 3.2, published by the DDAP Association. SC6 is seeking
additional input and participation from the industry as it finalizes these
standards to assure a process that can be utilized by the printing industry
with as broad an applicability as possible.
CGATS was formed in 1987 following a year-long assessment of the need for an
umbrella standards committee by the Image Technology Standards Board (ITSB) of
the American National Standards Institute (ANSI), and received ANSI
accreditation in 1989. CGATS' responsibility is to coordinate the entire
scope of printing and publishing technologies in one national standardization
effort, while respecting the established activities of existing accredited
standards committees and industry standards developers.
CGATS writes standards only where the need exists and no other committee is
undertaking the writing. Thus, in addition to developing standards for the
industry, CGATS also provides a vehicle for other industry organizations who
have specifications to work under the CGATS "umbrella" to move their work into
the standards arena, and have the work further developed and approved as an
American National Standard.
The committee works to improve the efficiency of national standards
development, facilitates information exchange, coordinates multi-discipline
standards activities and provides liaison for international
standards development. The committee currently has more than 65 members, with
over 100 organizations represented in the various CGATS subcommittees.
NPES The Association for Suppliers of Printing and Publishing Technologies
serves as Secretariat to CGATS. Information on CGATS activities and how you
can become involved can be obtained by contacting Mary Abbott, Director of
Standards Programs; Voice: 703-264-7200; Fax: 703-620-0994;
E-mail: 70732.2023@compuserve.com. Information on standards development is
also available through the NPES site on the World Wide Web:

NPES is a national trade association representing more than 300 member
companies engaged in the manufacture, sale and distribution of equipment,
supplies, systems, software and services for printing, publishing and graphic
communications. NPES is a co-sponsor of the GRAPH EXPO and PRINT
shows, the leading exhibitions of printing, publishing and graphic
communications technology in the Americas, and CONCEPPTS , The Prepublishing
Conference and Exhibition.
