FINAT Educational Handbook: Self Adhesive Labeling

Three completely re-written chapters on design, repro and press cover the critical early stages of a label’s evolution. Get it wrong at this stage and the results can be disastrous. The design process is extremely important to the success of a print job. There are many aspects which are interdependent and need to be brought together in a controlled way to ensure that the correct result is achieved. This chapter explores some of the issues that might be raised in the initial design stages of a label's development.

Repro is the process of finalising the artwork and producing working files from the design to the production specification with particular reference to colour separation, image quality, dot gain and image overlap which is known as ‘trapping.’ The repro process will ensure that the reproduction of the original label design, including the correct colour meets client expectations, within the tolerances of the chosen print process.

The pre-press procedure includes the creation of layouts, control and application of the step and repeat data, the imaging of films, the preparation and imaging of the printing plate ready for mounting into the printing press.

“It is important that designers, end-users and converters have a complete understanding of the design to print processes and the terminology used so that they can effectively communicate up and down the supply chain and ensure that each job consistency meets expectations”, Mr Shimmin continues.

Total Applied Costs

Often there is more than one way to decorate a product and each solution must be carefully evaluated before a rational decision can be made. Rather than looking at any one or more criteria in isolation a more appropriate approach is one that evaluates the total cost of labeling a pack to the required quality, performance and application speed, within a specified time frame. According to Mr. Shimmin, “some customers will continue to look at the price of the label and not the cost of the label, but it is clear that users are coming under pressure to consider a much wider range of cost factors when selecting the most appropriate method of decorating their product.”

Total applied costing includes a host of factors such as the cost and efficiency of label application, investment in capital equipment and machinery change parts, logistics and inventory control. This new chapter offers a new and invaluable perspective on the total cost of decorating a pack.

Substrates & Adhesives

A major advantage of self-adhesive labeling is its versatility, stemming from the range of materials and adhesives available. A completely re-written chapter on substrates and adhesives provides an overview of self-adhesive laminates and their characteristics, as well as the key issues involved in their production, selection and conversion. Adhesive and label substrate combinations must be compatible with the shape and surface characteristics of the item being labelled. It is important that both end-users and converters understand these relationships as they are key to making the right choices for product labeling.

Environmental Issues

The impact of packaging waste legislation and environmental concerns in relation to packaging is having an increasing impact on the selection of packaging components. The label as an integral part of the package must play a role in re-use, recyclability and disposal and must therefore be considered carefully during specifying process. This chapter provides an overview of the latest environmental legislation and its effect on the packaging supply chain.

“There is a need today to consider the total impact of labeling in the packaging supply chain and to develop co-operation across the supply chain to discover environmentally sound solutions,” says Mr Shimmin. “Schemes to recycle the liner used in self-adhesive systems as well as the introduction of linerless labeling are possible keys to its future sustainability. Readers will find these developments outlined in this new chapter on Environmental Issues.”

Continuous Learning

“With a thoroughly revised text and well-designed illustrations this latest Handbook will undoubtedly provide a regular reference source for all in the label and related industries and, in particular, a publication that should become necessary recommended reading for all new industry entrants and trainees. It’s thorough, comprehensive, well written, well designed and will certainly become a well-used resource for label industry suppliers, designers, label converters and all those that use labels on their day-to-day products and packaging,” says Mr. Fairley.
