Session 13: Printing Inks II
Chair: Ulrich Ott, Clariant, CHIn the second session on printing inks, environmental aspects of the industry will be discussed first. Further presentations will deal with new materials for printing inks, focusing raw materials for organic pigments, new effect pigments and the global rosin situation. In addition to the materials, technology is an important factor for the industry. In this context two examples will be introduced: a differential maximum bubble pressure technique and fountain solutions for offset printing.

Tuesday Afternoon 14.00 – 17.30 h
Room Istanbul
13.1 14.00 – 14.30 h Going green in inks Jack Baarends, Hexion, BE We have global challenges for climate, water, energy, communications, health and food. There is a growing need and a growing demand for improvement of our climate and our water resources, for the best use of energy sources, for safer and healthier products and we are more and more confronted with regulations and legislations. I like to discuss where ink makers and their suppliers should concentrate on to obtain sustainable print. I like to discuss different footprints, such as carbon footprint, energy footprint, ecological footprint as well issues on health, safety and regulations and where ink makers and their suppliers can make progress.  | ||
| 13.2 14.30 – 15.00 h Raw materials for Organic Pigments: Changing environment in highly volatile markets Heinrich Berger, Clariant, CH Considerable part of the value chain of raw materials for organic pigments has been moved to China and India in the last few years. By mid of 2007 the situation of raw materials for Organic Pigments and other Fine Chemicals started to change. Today, we are confronted with highly volatile global markets. While financial analysts mostly refer to the dependency of Crude Oil, it shall be presented that the reality of the market dynamics for many Fine Chemicals and Pigment Raw Materials is much more complex. | ||
| 13.3 15.00 – 15.30 h The global rosin situation Walter Jones, Pine Chemicals, US During the next few moments we will explore the three different types of rosin, gum, tall oil, and wood, and how each is derived. We will discuss a little about rosin chemistry and the component resin acids as well as commercial uses for rosin. As no presentation is complete without a history lesson, we will delve briefly into the colorful past of rosin. Next we will explore the “geography” of rosin and its current availability on a global basis. From a historic perspective we will review rosin pricing, and finally we will discuss a little about rosin’s “green’ nature as well as the future outlook for rosin. 15.30 – 16.00 h Networking: Refreshments & Coffee Break | ||
| 13.4 16.00 – 16.30 h A differential maximum bubble pressure technique Victor Janule, Chem-Dyne Research, US A unique dynamic fingerprint of any ink formulation can be generated in terms of surface tension versus surface age, from zero time to several minutes, using a differential maximum bubble pressure technique. This allows formulators and users to characterize ink performance under all possible conditions before the ink is used. | ||
| 13.5 16.30 – 17.00 h New effect pigments for printink inks Dr. Véronique Hall-Goulle, Ciba, CH Nowadays, effect pigments are widely used in decorative applications. Their effects rely strongly on flake geometry, including form (ranging from spheres to platelets), size (up to several 100 microns) and thickness (down to nanometer level). Producing highly intense effects in thin printed layers to obtain metallic, pearlescent or sparkle finishes, for instance, is a challenge. Effect pigments differ from classical organic pigments in that it is virtually impossible to reduce their particle size when dispersing them into their vehicles for printing without altering the ultimate desired effect. Challenges lie in formulating effect inks that combine suitable rheology, strong effect intensity and industrial printing applicability. Processes such as gravure, flexography and offset are less able to accommodate the particular geometries of inorganic materials than screen printing, which is highly suitable for large particles. This paper describes progress in effect pigments, enabling wider applicability in printing processes, substrates and different vehicles. | ||
| 13.6 17.00 – 17.30 h Fountain solutions - Important factor for offset printing Dieter Zang, Fujifilm Europe, DE Fountain solutions play an important role in the offset process. Building the correct ink-water balance, giving the right activation to the optimum protection to the printing plate are key factors to manage colour management and the quality required by the market. In the presentation different aspects of fountain solution starting from the used water quality and the composition to the need of reduce amount of IPA will be looked at. | ||
