output such as total ink limits, GCR/UCR, and so forth. Once you get
reasonable acceptable color appearance, you should convert that CMYK
document to your preferred RGB working space and
then
reconvert back
to CMYK with the proper conversion settings for the job the image will
be printed.
Tutorial #8: The Photoshop Soft Proof
The Proof Setup in Photoshop is the area where you load your specific
ICC profiles to produce a soft proof on screen of the eventual output from
your documents. The real power of the soft proof is when using the
Custom
submenu found in
Proof Setup
. Here you can pick any ICC
output profile that resides on your machine and save these settings to
quickly produce a soft proof. To see how this all works, let's do a step-
by-step and set up a soft proof.
1.
Open the
Printer_Test_File.tif
found on your CD. If your Color
Settings are such that you get an
Embedded Profile
Mismatch
, pick the radio button
Use the embedded profile
(instead of the working space)
to preserve the color space of
the document, thus allowing the document to open in
ColorMatch.
2.
Under the
View
menu, select
Proof Setup
and then the
Custom
submenu. The dialog seen in Fig. 9-8-1 will appear (the
actual profile seen may not match what you see in this figure;
don't worry).
3.
Click on the
Profile
pop-up menu and notice that all the ICC
profiles installed are listed on your computer but grouped in
such a way that all the working space profiles found in the Color
Settings (Working RGB, CMYK, and Gray) are toward the top of
the list. Below that are all the profiles that Photoshop has
installed on your machine, followed by all additional profiles
(grouped by color space). Choose
Euroscale Coated v2
, which
is a CMYK output profile.
4.
Notice that the background
Printer_Test_File.tif
image actually
changes its appearance as Photoshop produces a soft proof with
this profile. In a pop-up menu called
Intent
you can see the
effect of the various rendering intents on the preview. Choose
Relative Colorimetric
.
5.
For this part of the tutorial, we will save these settings. Click
Save
and when the
Save
dialog appears, name this
Euroscale
coated RelCol
and click
OK
. Photoshop will default to save this
setting file in the right location (the proofing folder) and as a .psf
