After the tobacco leaf has been prepared, it is put into moulding presses where it is put under tremendous pressure usually by means of hydraulics, here it is pressed into what is commonly known as Cakes. The Cakes are then placed into retaining presses, depending on the colour required of the tobacco it is cold or heated. The amount of pressure and heat will determine the final tobacco color. Flake tobaccos can be recognised through the slices that are sold, there are a few exceptions such as ready rubbed flake and partly broken flake. Plug and Bar tobacco is produced by moulding under pressure.
