This calendar was designed for the lighting industry company ES-SYSTEM. With the motto “light impressions”, it emphasises the core of the products offered by the company. The contrast of light and dark achieves a surprising effect: the individual pages of the calendar are made of alternating white and black paper cards, into which daily dates, names of months and number of weeks are cut. The clear and transparent calendar does not need any further paper printing techniques. Thanks to the visual effect achieved by available light, it is clear, convenient to use and reminiscent of printed calendars.
