1.01 Accessibility and Multi-Channel Publishing: Different Aims, Similar Solutions?

Ulrich Nikolaus

Accessibility, the attempt to make publications available for as many people as possible (especially for people with disabilities), seems at first glance to have little in common with (single-source) multi-channel publishing, the concept of using one single data source for the publication on different publication channels. However, both the technical solutions and the document structures used to achieve these goals sometimes turn out to be surprisingly similar. The similarities and differences between both concepts will be discussed, using the XML-based e-book standard “ePUB” and the accessible document format “DAISY 3” as an example. Furthermore, remaining technical issues and limitations that inhibit the seamless integration of accessibility in multi-channel publishing will be covered in detail.

Keywords: accessibility, single-source multi-channel publishing, XML, ePUB, DAISY

1.02 Using consumer preferences in setting the target for product development

Maiju Aikala, Mari Ojanen, Kaisa Vehmas

The need for market-driven product development in the paper industry has been realized. Traditionally, the product development in paper industry has focused on the production process and improving the existing products at competitive prices. However, the reason behind most of the unsuccessful product development projects has been the gap between product properties and the needs and expectations of the market. (Jokinen and Heinonen, 1987) The efforts to change the development strategies from product-oriented to customer-oriented have only recently intensified in response to global competition, market consolidation, overcapacity, price weakness and new technologies. (Lail, 2003)

Printing paper marketing is a typical example of business-to-business marketing. Although the decisions on the paper selection are made by the publisher or the advertiser, the final user is consumer - the reader. Thus, the preferences of the consumers are of the utmost importance also in paper development.

The objective of the study was to identify the required and attractive properties of silk coated papers in the end user point of view. The relationships between end use evaluations and sensory properties were also studied. The target was to find out how paper could be developed in order to differentiate positively from competitors within the silk coated paper grade.

1.03 Communication within the value chain of paper-print: visual perception and colour management on commercial publication paper grades

Luc Lanat

Paper and forest products are renewable, recyclable, sustainable, and bring emotions to end-user. Emotions and quality images are linked. This topic motivates active research.

In Communication within the value chain paper-printing, several misunderstandings appear:

  • Misunderstandings due to differences between printing equipments and papermaking equipments.
  • Misunderstandings due to differences in lighting conditions between papermakers and printers.
  • Misunderstandings between colour management prepress specifications and visual perception of white paper colour by itself.
  • Misunderstandings on printing relevant properties. Which paper properties are relevant for paper during printing?
  • Misunderstandings motivated by different interests between stakeholders: printing machine suppliers, papermakers suppliers, materials and software suppliers.

To clarify these misunderstandings, main conclusions of this paper are:

  • Perception of paper whiteness, evaluated visually through panels indoor, but close to Nordic daylight showed that Whiteness measurement is superior to Brightness.
  • Printing at constant target density, colour gamut, calculated as per C* sum reported in literature earlier, gave deceiving results. It is suggested that PPS roughness, although primitive, is more distinctive than shade references to select the right colour management profile, mainly linked to a paper type.
    Definitely, further work is here needed to come to any conclusion on Colour Gamut potential.
  • Colour Gamut discussions should integrate data made available by papermakers, as described in ISO NWI 15397 proposed standard and also detailed in this paper. Papermakers of Paperdam working group agreed to make available paper white point and publicly available characterization data to be used with their grades to their best knowledge. This is not a guarantee for “conformance” or “standardized printing”, but of course it is a preferred starting point and should bring printing consistency.
  • To reach targeted colours, ISO specified paper colour targets do not cover all market conditions. There is a clear need for evaluation of paper white point as a colour for best colour management calculations and avoid colour shifts versus targets.

Keywords: Quality, paper, printing, colour gamut, whiteness
