Hi,

I start to read infos about filmmaker znd other RIP, to replace our film output software and printer for a better one.
We may get an espon sc-p7000, now it is time to found a compatible RIP.

Could you please explain more about advanced AM/FM screening algorithm ?
Is that what is called an hybrid stochastic screening?

What kind of control do we have on the dots size in microns on the fm part ?
Who make the linearieation if I get it ?

Thank you !

The answer is a bit more complicated, in short yes it is a hybrid as it does use a stochastic (FM) and halftone (AM screen) in the screening process but its not the same as other traditional hybrid screens, hybrid screens are normally pre calculated based on certain dpi output, LPI requirements and angles. Because most of our customer base are not traditional offset users and have a wide range of halftone output requirements we developed a system that would work with any traditional halftone setting (so you can set LPI, Angle and spot function) and then apply the stochastic part to this screen. So its very different from anything else currently available from other manufacturers.
What we do is apply the stochastic screen on top of the AM screen and you can select how much to apply anywhere in the tonal range, so you can choose to apply this just in the midtones or only in the highlights / shadows and what it will do is start to break up the regularity of the halftone, if I applied in high value it will start to look like a stochastic.

What kind of control do we have on the dots size in microns on the fm part ?

As the FM part is applied to the traditional AM, it is the AM that determines the dot size.
Who make the linearization if I get it ?
We include a generic linearization and you can do your own with a densitometer.
