Bobst
Bobst was founded in 1890 in Lausanne, Switszerland. Meanwhile the company grew enormously. Nowadays Bobst has 11 production plants in 8 countries. Bobst started with the production of machines used for producing cardbord. Since the acquisition of Schiavi, Rotomec and F&K the company has also a wide range of machines for printing and producing flexible packaging.
Flexo printing presses
The first printing press was introduced in 1440. Those presses were used for printing paper and books. There have been a lot of improvements, especially during the industrial revolution when the first industrial printing press was designed. In 1890 the first flexo printer was invented in Liverpool, England.
Flexography, or flexo, is named after the flexible relief plate that is used to print. Flexo printing presses can be used for plastic, film, cellophane and paper. Flexo machines are the most common machines in food packaging. In 1952 the official name for this type of printing was announced: Flexographic process or short, flexography.
Last decades there were also a lot of improvements, especially in the digital printing field and the amounts of colors that a press can use. There are several types of flexo printing presses: CI presses, stack presses and in-line printing presses. CI stands for Central Impression. Those flexo printing presses have an impression cylinder. Stack presses are used for multi color printing. It is called stack because each color station is stacked vertically. Stack presses have two to eight seperate color stations, sometimes they have two parallel stacks of printing units. The third type of printing presses, the in-line presses, have seperate, horizontal color stations from front to back.
