QTR-Quadtone RIP

Brian,

I'm pretty sure you can set the platen gap from the printer control panel and that setting will be applied unless it is overridden by a software setting. Since QTR does not have a platen gap setting, as Roy has confirmed, this should be the case here. It has worked that way for me over the last 8 years with 3880s and 3800s. Stated another way, I'm fairly certain that the setting QTR uses is whatever you have set at the control panel. There is no AUTO setting on the control panel platen gap.

As for color printing with the Epson driver, my understanding is that each media setting has a pre-defined platen gap setting as part of it's configuration. That doesn't mean you'll be able to figure out what it is. ;) But if you are consistently getting head strikes using Canson's recommended settings then why not create a special paper configuration with a wider platen gap? See pages 43-45 of the manual.

Cheers,
Keith

There's no option to set the platen gap, so one has to assume it's using the "standard" setting.  No head strikes.  But if I use the sheet feeder and the Epson colour driver then I do get head strikes.  I'm using the Canson recommended media setting of Premium Semi-Gloss and this sets the platen gap to "auto", whatever that means in this context, and the paper thickness to 3.  I'd like to know what setting QTR is using by default, so that I can use that for colour printing.  Any tips?
