All exercise books were produced at the Ökodruckerei Plöchl GmbH. This printing company is a pure
family business, which was founded in 1889 by Friedrich Plöchl. The current owner is Bernhard Plöchl.
Apart from the Junior Edition Oboe (staple binding), all exercise books were produced with a high-quality thread binding.All exercise books were produced by the eco-printing company Plöchl in
Austria (Freistadt), thus guaranteeing the longevity of this product when handled properly. In addition, a special "soft glue" is used on the spine so that the exercise book can lie
straight on the music stand. The surface of the cover is cellophane-coated, which means that it can even be wiped clean with a damp cloth.
The layout of the exercise books was designed by Gernot Daucha: Gernot Daucha
