Abstract
A method and an apparatus for identifying mapping of a paper machine by means of a mapping test. The invention comprises forming a mapping model which takes the linear and non-linear shrinkage of a paper web into account. The mapping test result is analyzed to form a non-linear shrinkage profile and a linear mapping error from it. The linear error and the non-linear shrinkage profile thus obtained are used in the mapping model.
