Munich-based printer Gotteswinter und Aumaier GmbH produces an annual Streifenkalender, a vertical strip calendar, for their customers. The 2020 version ‘brings a lot of colour to the office’ says Bernd Weber, Gotteswinter’s head of sales and marketing. A spectrum of vibrant papers is interleaved with strips of Sirio Black that are printed with an array of intense coloured inks. ‘Black paper with black binding gives the calendar an exclusive look,’ says Weber.
