It appears that bitmapped TIFFs get converted to RGB in PDF (which are destined for one-color printing). I'm no expert on image formats, but this surprises me a bit. Is there a workaround?

Thanks,

It should be grayscale, right? I think we handle this for PNG, perhaps we overlooked it for TIFF. I will investigate.

Actually, would you be able to email me a sample bitmap TIFF image that I could try here?

Just emailed you a file. Thanks!

Thanks, we didn't support 1-bit black and white TIFFs, but we do now!

Prince 10 is now available, and supports 1-bit TIFF images.
