Blueprint in Burgenland involves the dyeing of fabric with the help of a special type of printing technique called Reservedrucktechnik (resist printing). Traditionally, wood patterns and paste are used to apply the requested design onto the fabric, which is subsequently dyed indigo. It is said that textile printing was probably discovered by chance and can now be traced back for centuries in countries such as Hungary, Turkey, the Czech Republic or Egypt.
In 1930, the Koó family purchased a roll pressure machine, which is still used today in its third generation for the production of double strike, the familys speciality. The wood patterns applied for printing are more than 100 years old. The Koó family has only a few written records on the composition of the paste; knowledge about its special components is passed down from one generation to the next.
