AFAIK CX screening was shown (e.g. at Drupa and at customer events) - but never released as a product. Maxtone always allowed the customer to configure the min and max dot sizes but "CX" would have extended that capability to FM. So Kodak was going to have had a unified screening suite: Maxtone for AM and Staccato for FM - both being customer configurable - hence the "CX" designation would be appended to both. But as I said, AFAIK, that did not happen which is why the "CX" designation is not included in the Maxtone product info.
Maxtone Cx Screening released in Kodak Prinergy Evo 5.1.6.11
maxtone screening like hybrid.
but in AM screening and it use on termoflex
Yeah, it's just a naming change not a technology change or introduction.
The CX means configurable.
Maxtone was always configurable. It is the basic Creo/Kodak AM screening (Creosettes, Cadence, etc (different names same AM screening product) with the ability for the customer to configure the minimum dot size. So, the names Creosettes, Cadence, etc. was to become Maxtone CX. I.e. dial the option one way and it's basic AM screening. Dial the option another way and you change the minimum dot size.
Put another way:
Old names - Creosettes and Maxtone.
New name - Maxtone CX
But I didn't think that Kodak had actually changed the Maxtone name to Maxtone CX - there web site does not show this name change (is your Maxtone is actually named Maxtone CX in EVO?). Remember it's just a name change to unify the screening names.
