[For some reason, the post showed up blank. Trying again as plain text.]
We used to use ColorBurst X-Proof with our old Epson SP 4800 for CMYK
proofing, but it is not supported on our new SP 4900.
I see that the Overdrive RIP works through the Epson printer drivers, to
which it passes RGB data. For an InDesign workflow, that means
generating CMYK PDFs, which it converts internally to RGB data for the
Epson driver.
So I'm wondering if, without its also having any controls for ink
limiting or linearization, if there could really be any advantage
compared to sending the same PDFs direct to the Epson, using Acrobat
Color Management.
The potential areas of difference that I can see might be:
* A different CMYK conversion. I don't know what engine Overdrive uses
to convert CMYK to RGB.
* A potentially different RGB color space that is passed to the driver,
though since I believe the Epson driver is optimized for either Adobe
RGB or sRGB input, that it would be Adobe RGB.
But what else? Is there really any need at all to spend $795 for that?
Thanks in advance for any clarification.
