Foil is formed after printing, so deformations should be accurately predicted. Popular and suitable for cost optimization, shrink sleeve packaging in the hands of a skilled designer can be a powerful weapon of marketing strategy. But if the basic rules of geometry and some of the crucial characteristics of the foil are neglected, sleeves can do more harm than good to the brand.
The prepress for shrink sleeves is very complex because the material is formed after printing under exposure to heat. In this process, the material adapts to the shape of the packaging and it is necessary to accurately predict and compensate for all the deformations in the artwork phase.
