but of differing size in a single job.
For Monochrome impression I propose the first part of the definition read as
" A Monochrome Impression is an Impression imposed using [versus
requiring] a single colorant.....
Disagree strongly. An accidentally monochrome image from a color source
(that is, a color image that happens to contain only one non-blank color
channel) is processed very differently from an image that contains only one
channel of color data. The halftoning done by the printer RIP, for
instance, is very different for images with different color channels, and
produces very different results.
We should continue to specify a monochrome image as one that *requires* only
a single colorant. A color image that accidentally consumes only one
colorant is still a color image, albeit with impoverished color saturation.
(It took me several hours recently to explain the difference to an expert
photographer who was baffled by the interaction between his Photoshop
actions and his color and monochrome printers. The differences were easily
visible to the naked eye, but I had to show him the reason for the
differences with a microscope.)
[gwp] Ok, my mistake, I took a single colorant to mean a single "dye,
pigment, ink, or paint" versus a colorant's (color) value.
