A second software application is needed to convert the percent coverage in an ink zone to the correct key setting. There is a direct (but not linear) relationship between coverage and correct key setting. Presetting software uses this relationship together with the zone coverage data to calculate the required setting for each key on each fountain. Because fountains are not identical, most systems provide a means to account for these differences in the calculations. Some systems also provide a means of adjusting the key settings based on the characteristics of the material being run.
