already manipulated images from another source and convert the imported
file into an EPS file) and Quark express to put the images onto a page and
output to an imagesetter. The marriage of Photoshop and Quark in this way
is magnificent. Photoshop can generate a five-file set of CMYK color
separated EPS files plus a 'master' EPS file that is used by Quark for
placement on the page. This is called the 5 file DCS ('desktop color
separation') format. It is truly wonderful. Each of the separate CMYK EPS
files is about one fourth the size of the original composite CMYK image.
The master EPS file is much smaller. Quark loads only the master file and
displays the low resolution image contained in it. The process is very fast
and transparent. Also, Quark can output a properly prepared DCS set very
rapidly.
It seems to me that Black Belt is in a position to create just such a file
standard right now with very little effort. Pgs and ProPage could benefit
from adopting the standard. I could see no reason for them objecting to it.
As a matter of fact, if they accepted it, they could use files output from
Photoshop in the 5 file DCS format.
One more comment (plea). Could IM be made to load an 8 bit gray scale image
without generating a 24 bit internal file? A great deal of graphic art
industry image manipulation still is and always will be of monochrome gray
scale (black and white) photos. The computer overhead that IM places on
black and white images is unnecessary. I appreciate the fact that the
program was conceived as a 24 bit image manipulator from the very
beginning, but I hope that you can see the need for manipulation of
high-resolution black and white images.
BTW, I haven't downloaded the latest version of IP in several weeks now.
That probably means that I am working with a hopelessly outdated version!
