Probably not, but you surely need an organised, consistent and repeatable printing system.
If I look for a nut suitable for an M4 screw, I just have to look for an M4 nut to make sure I have the right nut.
An organised and repeatable system has a better economic and quality yield. This is why it is necessary to organise the production system in an optimal, efficient and effective manner.
A system is under control when we are able to know its dependencies, relationships and its result. For this it is necessary to calibrate our flexo production system in order to be able to determine the result.
