KoskiFlex Christmas card

Koskisen's Christmas card 2013

600 sheets of KoskiFlex – the thinnest birch plywood available in the market – an expert printing house, and a dash of creativity. That is the recipe for Koskisen’s Christmas card last year.

Our Christmas Card project was started up rather late last autumn, as our thoughts turned to the Christmas season and how we would remember our staff, customers and co-operation partners. Right from the start it was clear that, in addition to expressing the company’s gratitude, Koskisen also wanted to give the recipients a memento of the company. So it was only natural to print a Christmas card on the company’s own product.

Flexibility offers many possibilities

As the name implies, KoskiFlex is a thin and flexible material. Koskisen’s Christmas card is printed on 0.4-mm thick 2-ply sheets, but the product is available up to a thickness of 2.5 mm. The advantages of its flexibility are best displayed in thicknesses of less than 2 mm. The wide range of thicknesses introduces many possibilities for different end uses. KoskiFlex can be used to make lamp shades, scale models, and, of course, labels and cards, such as business cards.

“In Finland, sales of KoskiFlex have been growing in recent years, especially for lamp shades and business cards. It’s great that customers have found such a unique product,” says Raimo Kämppi, Domestic Sales Manager for Koskisen’s Birch Products unit.

The advantages of KoskiFlex are also the product’s eco-friendliness, water and heat resistance, and the possibility to colour, wax or lacquer it. In addition, KoskiFlex can be machined using wood machining tools, which means that, for example, waterjet cutting and laser cutting are possible.

Unique printing surface

KoskiFlex was the clear choice for the Christmas card right from the start, as the birch plywood brings the feel of genuine wood to printed products – something that cannot be achieved with board materials. It also brings the printed image to life on the plywood.

“The printing result can even be astonishingly good. The sharpness and colour reproduction can be maintained even in smaller texts and details,” says Tuomo Honkavaara, Markprint’s Product Manager.

Markprint has decades of experience in demanding printing jobs, and this was one challenge the printing house was eager to take on. The Koskisen Christmas card was digitally printed, but Markprint also offers two other alternatives that can be used to print on KoskiFlex: traditional printing and UV offset.

Important aspects to pay attention to when printing on KoskiFlex are the correct temperature and air moisture to ensure the material does not curl. Markprint has a humidifier system in its production areas to ensure the printing material maintains its shape.

When making Koskisen’s Christmas card, one problem that arose was that the material would curve too much, but Markprint was able to offer an alternative printing method. All in all, Honkavaara considers KoskiFlex an interesting print material.

“Printing on it is challenging, but fun. For a project such as this one, it is important to ensure proper scheduling and to begin planning well ahead of the deadline, as KoskiFlex does not conform to the same printing rules as those for regular paper or board,” explains Honkavaara.

The Christmas card will not be the last project Koskisen and Markprint co-operate on with KoskiFlex: they are already working on Koskisen’s business cards, which are expected to be ready within a couple of weeks.

The standard sizes of KoskiFlex are 1200 x 1200 and 1450 x 1450 mm. The delivery time ranges from 4 to 6 weeks. More information is available from Heikki Kiesilä at +358 50 516 8923
