From Manfred Breede:
This app calculates the total creep and the distance that image areas of each page in a saddle-stitched product have to be moved progressively toward the spine, in accordance with their position relative to the center of a book block. In addition, a "Creep Tweak" function can be used to compensation for variable folding machine adjustments.
This update has been internationalized for people in different parts of the world who use the period or the comma as a decimal mark. When users enter their preferred decimal mark the app will automatically replace a comma with a period.As well, the app icon has been redesigned to better reflect its utility.
