Re: tvi on plates
I feel that you'd want the color bar to be representaive of the live area of the press sheet, so yes, the control bar should have the same compensation as the rest of the job. That said, I know of other companies, some quite reputable, whose process control software alledgedly only works with typical screening, so even when they're using FM screeing, they utilize a linear AM 150 lpi color bar. However, in this scenario, its possible that there are proccess control issues that affect FM screeing before it would be noticed on an AM color bar, so its risky in my opinion.
In any event, I would also recommend that a plate control element be imaged that shows both the default exposure ("linear") response of the plating system, as well as the Rip compensation applied to the file, so you at least know what's what on the plate.
