4.10 Hybrid Media on Packages

Ulf Lindqvist, Maija Federley, Liisa Hakola, Mikko Laukkanen, Aino Mensonen, Anna Viljakainen

Abstract
The packages are expected to carry ever more information in a limited space. One solution is hybrid media, i.e. printing intelligent elements on the packages. The aim of this study was to find the best way to produce additional business to the value chain of packages via already existing technologies for hybrid media.

The approach included a technology survey about 2D applications, interviews with industrial experts from the package value chain, two industrial case pilots with user studies and a study tour to forerunner companies in Japan.

Hybrid media can give benefits in form of cost savings, new business opportunities, additional value to already existing business and increased customer loyalty to all players in the value chain. Available hybrid media technologies are 2D bar codes, digital watermarks, image recognition, fibre matrix, RFID tags and magnetic codes.

Pilot tests and user studies showed that additional hybrid media service should include detailed product data, recipes, nutrient need, user instructions and matching of user demand. Obstacles for use are costs, time consuming and complexity.

In Japan mobile barcodes are part of everyday life, well known to consumers and used on flat rate basis. The introduction was from the beginning based on consumers’ needs, not on early profit. Today it operates on a win-win principle with benefits for all the players in the value chain and several traditional printers have created completely new service concepts for their customers.

4.11 Ensure product longevity and quality at printing on balloons and other stress-deformed materials

Anna Vyacheslavovna Erofeeva, Alexander Petrovich Kondratov, Evgeny Borisovich Bablyuk

Abstract
One of the main problems of screen-printing on the deformed surfaces of elastic materials, in particular on elastic balloons, is a limited range of inks that can be used for working on elastic materials. It is explained by their low durability in stressed-deformed state and low resistance to solvents and other ink organic components, in which the balloon material (latex film, rubber, synthetic elastomer) intensively swells, or which can cause cracking of its surface. To increase technological capabilities and competitiveness of specialized printing companies dealing with printing on balloons and other products made of deformable elastomers, the following are essential: carefully selected formulas of the used materials, improved ways of screen-printing and research of the three-dimensional rubber deformation features. These problems can be solved by physical simulation of a three-dimensional rubber deformation processes in contact with aggressive liquids.

Keywords: screen printing, solvent, balloon, longevity, deformation limit, latex rubber.

4.12 Examination of the factors influencing the adhesion power between the layers of laminated plastic cards

Erzsébet Novotny, Ildikó Endrédy, Csaba Horváth

Abstract
Plastic cards are applied in many fields of our lives. They can be documents and bank cards, as well as club cards and loyalty cards. Their body is made of several plastic foil layers with lamination.

Our research focuses on the adhesion problems between plastic foil layers which can be influenced by several factors during the manufacturing process, including the type of ink, the quality of the foil and total ink coverage. The most important of them is the effect of the printed surface’s total ink coverage. The purpose of our investigation is to determine the maximum total ink coverage that provides a just appropriate layer adhesion after lamination.

We printed plastic card samples with different TIC values, using CMYK process inks. We established that from the point of applicability maximum total ink coverage can be 280-300% and individually the four basic colours show very good layer adhesion results.

The presence of black and cyan colours in high percentages adversely influences the adhesion force between the layers. The maximum total ink coverage can be increased if their proportions are reduced, this would, however, result in a lighter shade of colours not suitable for all card designs.

Keywords: plastic card manufacturing, total ink coverage, adhesion between layers
