WEPT is a week on electronic publishing and typography from Monday, April 11
to Friday, April 15, 1994. Two international conferences

_____RIDT94 Raster imaging and digital typography

_____EP94 Electronic publishing, document manipulation and typography

and two international workshops

_____PODP94 Principles of document processing

_____TEP94 Teaching electronic publishing and digital typography

are scheduled for the same week at the same place.

Tutorials are offered and may be visited by any participant. Registration
to tutorials or workshops can be made independently of any conference

WEPT discusses the current research topics in electronic publishing. It
brings people together who usually do not meet, although they work on
related topics. The week will be held at the Lufthansa Training Center,
at Seeheim, near Darmstadt, Germany, which will be the place for
lectures, demos, conferences, meetings, and also for accommodation.

RIDT94 Raster imaging and digital typography

Monday, April 11 - Wednesday, April 13

RIDT94 will be the third in a series of international conferences
organised to promote the exchange of novel ideas in the area of raster
imaging and digital typography. The first two conferences in the
series, RIDT89 held in Lausanne (Switzerland) and RIDT91 held in Boston
(USA), mainly concentrated on the rasterisation of outline characters
and on digital halftoning; RIDT94 will emphasise rendering and font

PODP94 Workshop on principles of document processing

Monday, April 11 - Tuesday, April 12

PODP94 will be the second in a series of international workshops
organised to promote the modelling of document processing systems using
theories and tools from computer science, mathematics, etc. Areas of
document processing presented in the first workshop in Washington, D.C.
were document formatting, document conversion, document representation,
document recognition, document retrieval, and hypertext, among others.

TEP94 Workshop on teaching electronic publishing and digital typography

Tuesday, April 12 - Wednesday, April 13

TEP is an EP workshop discussing the teaching of electronic publishing.
Some curricula and courses are described in terms of the areas to be
covered and also the experiences gained through running a course. More
specific issues are addressed concerning methods of teaching with some
examples of the types of projects engaged in and the skills that are
acquired. The teaching of multimedia is focussed upon as a form of
electronic publishing that presents its own challenges.

EP94 Electronic publishing, document manipulation and typography

Wednesday, April 13 - Friday, April 15

This conference will be the fifth in a series of international
conferences organised to promote the exchange of novel ideas in the
area of computer document manipulation. The first two conferences in
the series, EP86 held in Nottingham, England, and EP88 in Nice, France,
concentrated mainly on the specific aspects of electronic document
production, from composition to printing. EP90, which took place in
Washington, adopted a broader definition of the term Computer Assisted
Publication, and accordingly, extended its range of topics to include
hypertext and hypermedia systems, document recognition and analysis,
and application of data-base techniques to document handling. EP92,
held in Lausanne, Switzerland, confirmed the trend for documents to
affect more and more areas in computer science; EP94 follows this

Tutorial 1 Designing and authoring hypertext documents

This tutorial is intended for those wishing to understand the many
forms and uses of hypertext documents and the various approaches to
their creation. Some rudimentary acquaintance with the technology will
be expected, but attendees need not be hypermedia implementors. This
tutorial is appropriate for anyone interested in creating educational
(academic or industrial), instructional, or creative electronic
documents or who wishes to survey real-world applications of hypertext
and hypermedia. The instructor will provide both paper and electronic
examples that those enrolled in the course can take away with them to
use as templates or practical examples of the issues discussed. Topics
to be addressed include:

1. Kinds of hypertext/hypermedia systems: Some basic forms such
as text-based systems, multimedia delivery systems, and
conceptual analysis systems, examples and demonstrations of
currently available systems.

2. Basic design and conceptual issues: Reference vs.
read-through texts: a valid distinction? - Single vs.
multiple-window systems - Adaptive (from print text) vs.
originally created for electronic environment - Axial vs.
network organisation - Stand-alone vs. networked systems.

3. Forms of linking, their uses and limitations: Document to
document - String to string, or string to document -
Many-to-one links, One-to-many links - Action or process links,
typed links - Problems with visual and sound materials.

4. Lost in hyperspace: problem or nonproblem? Orientation,
reading histories, and navigation - System- vs.
author-generated devices - Rhetoric of arrival - Rhetoric of

5. Authoring hypertext/hypermedia materials: Organising devices
for electronic media - Choosing electronic book vs. electronic
library model - Effective length of reading unit (chunk, lexia,
space, document) - Effect of hypertext upon reference notes -
Reuse or repurposing: materials for multiple access 6.
Hypertext modes and genres: Reference hypertext - Educational
hypertext - Literary, artistic, and experimental uses.

George P. Landow is Professor of English and Art History at Brown
University and Faculty Fellow at the Institute for Research in
Information and Scholarship. He holds the AB, MA, and PhD from
Princeton University and a MA from Brandeis University. Landow has
written and lectured internationally on educational computing and
computer hypertext. He has supervised, edited, and written various
large hypermedia documents.


Tutorial 2 SGML and databases

Various approaches for combining SGML and database technologies are
presented. Focus is set on introducing generic concepts and methods and
proposing a tool taxonomy, rather than presenting a catalogue of
available software tools (which are however mentioned as examples,
including some demos).The objective is to provide the audience with an
extensive and structured overview of SGML and database relationships,
and associated tools available for the development of SGML

Attendees should be familiar with the SGML concepts and
language and have a concrete interest for using database
technologies in the framework of SGML applications. Topics: -
Non-SGML databases: storing SGML data in databases - producing
SGML documents out of databases - SGML databases: representing
SGML documents as databases - SGML query languages - SGML
databases and large document manipulation - SGML-based
editorial engineering workbenches - SGML-based electronic
document distribution

Francois Chahuneau is managing director of BL/AIS, a French company
specialising in SGML-related technologies and providing consulting,
systems integration and software development services. F. Chahuneau is
a frequent lecturer in international SGML conferences and tutorials.


Tutorial 3 Multimedia and typography

The tutorial is intended for editors, graphic designers, and software
developers who are concerned with handling text in multimedia
presentations, on its own or in association with illustrations

First part: - Fonts: Differences in display objectives between
multimedia and desktop publishing - The display surface in
multimedia - Typographic function and the question of style
- Font production technologies: Rasterisation and hinting -
Algorithmic recognition of letterform structure - Binary and
greyscale fonts - Font quality - Font formats: Display software
- Metrics and kerning - Cross-platform working and display

Second part: - Layout: Principles of text layout - The reading
task in print and multimedia - Differences between paper-based
and electronic displays: Access mechanisms - Indexes and links -
Paging and scrolling - Dynamic formatting and graphic structure
- Design for print and design for multimedia: Relationships
between text and illustrations - Colour - Multimedia and
tradition in printing and publishing.

Richard Southall is a typographer and font designer with a
longstanding interest in the graphic and visual problems of
presenting text on electronic displays.


Tutorial 4 Introduction to desktop colour reproduction

Today's desktop computers and peripherals support the creation,
visualisation, and printing of colour documents. Nevertheless,
without appropriate calibration of input and output devices,
colour originals will not be rendered faithfully. Furthermore,
low-cost desktop colour printers may produce visible Moire
effects. This tutorial intends to provide an introduction to
colorimetry and to colour reproduction. It is divided into an
introduction to colorimetry, an introduction to halftoning and
colour reproduction and a survey of means for colour support in
commercial systems.

1. Introduction to colorimetry - Francoise Vienot The scope of
colorimetry is to provide the specification of colour. Basic
colorimetric concepts and the cie colorimetric system will be
reviewed: standard colorimetric observer - CIE standard
illuminants - calculation of CIE tristimulus values - use of
the chromaticity diagram - colour difference formulae. In
addition, the recent development by CIE of "a fundamental
chromaticity diagram whose coordinates correspond to
physiologically significant axes" will be presented.

2. Introduction to halftoning and colour reproduction -
V. Ostromoukhov, I. Amidror, Roger D. Hersch High-quality colour
reproduction can only be achieved by appropriately calibrating
input scanners and output printers. A method for the
calibration of input and output devices by using 3D tables will
be presented. Superimposed rotated grid layers may produce
Moire effects. A short analysis of Moire interferences in the
spectral domain will provide information about acceptable
solutions minimizing Moire effects. While solutions exist for
Moire-free reproduction at high-resolution, the generation of
Moire-free images at desktop printer resolution is still an
open problem. A brief review of current colour multi-cell
clustered-dot halftoning techniques will be given, based on
published patents and patent applications.

3. Colour support in commercial systems (Apple Colour Sync,
PostScript Level II) - Michael Hass Commercial systems start to
offer facilities and support for calibrated colour image
acquisition, display and reproduction. This talk will explain
and review the features offered by interfaces such as Apple
Colour Sync and PostScript Level II.

(Fogra, Muenchen)


Tutorial 5 Designing information for the computer screen

The overall goal will be to help participants see and
articulate the elements of good screen design. The purpose of
the workshop is as much consciousness raising about the value
and vocabulary of design as it is a collection of practical
tips. This tutorial is intended for computer professionals
responsible for or working with information to be read on the
computer screen.

No formal background (or talent) in design is required. The
tutorial will focus on fundamental aspects of visual
communication as they apply to presenting information on the
computer screen. A slide lecture will illustrate the issues
symbol and representation and how these channels of visual
coding are used when presenting information in two-dimensional
space. Historical examples will show how code and structure is
established in a wide range of cultures. These will be related
to current examples of computer applications and hypermedia
publication design. Much of the tutorial will be devoted to
techniques for developing computer icons.

Slides that illustrate icon language in several popular
computer applications will be discussed and analysed. The
participants will then be asked to work in groups on a simple
icon design assignment. The results of this assignment will be
shared and discussed.

Paul Kahn has been involved in the design of hypermedia
materials since 1985 at Brown University's Institute for
Research in Information and ScholarshipJ(IRIS). Krzysztof Lenk
has been professor of graphic design at the Rhode Island School
of Design since 1982, specialising in typography and
information graphics. In February 1991 they formed the
information graphics firm of Dynamic Diagrams Inc.


Tutorial 6 Modelling human vision

While the advent of digital imaging poses new and more complex
problems to the quantification of image quality, it also allows
more detailed modelling of the human visual system via image
processing. These resulting visual models can provide for more
accurate descriptions of image fidelity, which is the subset of
image quality that specifically addresses the visual
equivalence between two images. Such models are also making
headway into the more general field of image quality as well.

This tutorial will begin by describing fundamental properties
of human vision that relate to image structure. It will then
describe how these properties have been modelled as components
of the visual system by using digital image processing.
Demonstrations of the results of the cascade of these image
processing components will be shown for a variety of
distortions in various applications (including text and digital
halftoning). Finally, the performance of such image processing
models of the visual system will be quantified by explicitly
simulating psychophysical experiments.

Scott Daly is a research scientist in the Imaging Science
Division of the Eastman Kodak Research Laboratories. He has a
BS in electrical engineering from North Carolina State
University where he concentrated on image processing. After
working a number of years in industry in the fields of video
(RCA Corporation), photographic laser scanning (Photo
