Principle of AlphaTack measurement

Tack measurements usually provide a tack value which includes the film splitting force
combined with contributions from the elastomer roller elasticity, ball bearing friction and
forces for ink film formation.
Owing to its innovative technical design the AlphaTackPlus overcomes all the principle-
based difficulties of the usual tack measuring method. A solid state force sensor is
embedded seamlessly into the surface of driving metal roller. This sensor measures the
complete pressure profile in the roller nip and transfers this data to the PC after each nip
passage.
