What is Maximum dot and Minimum dot is actually mean?
For my own interest, I would like to know what maximum and minimum dot is really mean in print world. Especially rotogravure world.
My assumtion for minimum dot is in what percentage of screen value can be achieveable when printed. For example, 3% of screen black will be engraved to rotogravure plate as small dot shape and ink can be transferred. if 2% of screen black is not printed then you minumim dot is 3%.
For Maximum dot can be where 92% black is engraved, however due to dot gain, your density is almost comes as 100% black.
Am I right on this assumtion or totally wrong track?
If you are press operator and need to find your mximum and minimum dot, how do you find the value in %?
thanks
