As the family of four setout to buy some warm coats in a sports shop, they discoverthat modern printing processes are helping to createsurprisingly individual products.In Hamburg, at just after 8 o’clock, Tim Wegmüller wakesup in his hotel room and opens his eyes. The previousevening, he had arrived by train with his sister Anna,father Florian and mother Gloria. The week’s holiday innorthern Germany is a reward for passing his probationaryperiod at the grammar school. Tim jumps out of bedwith excitement and pulls the curtains open. Instead ofseeing the blue skies and warm rays of springtime sunshinethat he had hoped for, he scowls in disappointmentat the dreary clouds. After a glance around at the swayingbirch trees in the hotel courtyard, his suspicions are confirmed:it’s still rather gusty outside. “If only I’d packedmy warm jacket,” he thinks.Half an hour later, he meets his family in the breakfastroom. “I’ve got a bad feeling that the weather forecastfor pleasantly warm weather was merely a ploy by thetourist board,” says Gloria Wegmüller. “I’ve just been fora walk around the hotel, and it’s extremely cold.” FlorianWegmüller takes a sip of his coffee. “We don’t have theright clothes for this kind of weather. I think we’ll have tosort out something a bit more appropriate.” “Fortunately,having to go clothes shopping isn’t the worst thing in theworld,” Gloria jokes, winking at her daughter. And so, theWegmüllers set off for the shops.Scarves of all coloursA short walk later, the family comes across a large sportsshop. But before they get to the warm jackets, Tim turnshis attention to a shelf stocked with multi-functional,tube-shaped scarves. “These are so in right now,” heshouts. “All my friends at school have a scarf like this,even the English teacher.” “Mine too!” says Anna. “Youcan wear these scarves in lots of different ways, like ascarf or a bandana. My friend Martina wears hers as ahairband. We could all do with a scarf with this wind.”Gloria and Florian briefly look at each other in agreement.“You can both pick one out of them,” says Gloria, adding“but if everyone’s wearing one, doesn’t it get boring?”“Not at all. Look, Mum. There are so many colours anddesigns – no two are the same,” explains Tim. Suddenly,Florian starts to take an interest. As a Purchasing Manager,he knows how important production output is tothe price of a product. “How can the manufacturer offersuch diversity but sell them at an attractive price?” hewonders.
Digital Imaging25Digital printing brings benefits for customers andretailersA member of staff at the sports shop, who overheardthe family’s conversation, comes over. “It’s to do withthe printing,” he explains. “These products are printedusing what’s known in the industry as a digital sublimationprocess; this helps to create a large range of diverseproducts in small quantities. For us as a retailer, thismeans we don’t need to keep as much stock and canorder more very quickly if there is high demand. And asyou can see, customers benefit from an extraordinarilywide range.” “When I think of ’printing’, I think of paper,not textiles,” says Gloria sceptically. The sales assistantreplies, “You’re not far off. Actually, so-called sublimationpaper is used in the process – the pattern is printedonto this paper and then transferred to the material usingheat.” “Clearly, digital printing is now conquering the textileindustry,” Florian Wegmüller concludes, and thanksthe knowledgeable assistant.Digital sublimation printingWith digital sublimation printing, a design ismirror-inverted and printed on sublimation paperusing special inks and an inkjet process. Theprinted paper, together with the material to beprinted on (polyester fabric or polyester-coatedhard substrates), is subsequently inserted into atransfer press. At a temperature of between 160and 210°C, the printing process turns the ink intogas. The dyestuffs are released from the paperand fuse with the polyester fibres. The result is apermanent, colourfast, razor-sharp printed image,without a colour application that is noticeable tothe touch.In the meantime, Tim and Anna have picked out a scarfeach. “Come on Florian, let’s get one too,” says Gloria,choosing two designs for herself and her husband. A fewminutes later, the Wegmüller family leaves the sportsshop – complete with new warm coats and a cool scarfeach around their necks.“We can offer our customers maximum diversity, while keepingstock levels low, thanks to efficient digital printing processes.”
