Calculating area coverage values and ink con­sumption for paper only

In practice, there are cases in which image data (3) are also present on the printing plate (1; red frame) even outside the paper to be printed (2; yellow frame) (see illustration below). For example, there can be 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.
