Calculating area coverage values and ink consumption for paper only

In practice, there are cases in which picture information (3) is also present on the printing plate (1; red frame) outside the paper to be printed (2; yellow frame). For example, plate control elements which are not printed. In order to calculate the ink consumption correctly in these cases, only the part of the sheet in which the paper (2) is also present may be taken into account in the calculation. The paper information must be transferred correctly from the prepress system in order to produce a cor­rect calculation. As this is not guaranteed on all prepress systems, this function must be specifically activated.
