Photoshop: Understanding soft-proofing | lynda.com

September 4, 2019


In the last movie I showed you how to set
up the proper Color Management settings, and now I would like to show you how you can
put those settings to good use by applying Soft Proofing. It’s important to understand this concept
because then you can apply it as you are working with your images,
and preview how your images are going to look when they are output before you actually convert
them, and output them, and that’s what Soft Proofing
is. So what I would like to do is here in Bridge,
I am actually going to open up the exercise files folder, go into Chapter 2,
go into the soft proofing folder and we are going to double click on flower.TIF. That’s going to open up our image here in
Photoshop. Now next thing I want to do is I am actually
going to change to Standard Screen Mode by clicking
down here and choosing that from the fly-out menu. You can also do that by hitting the F key
three times, scroll through those different View Modes by hitting the F key. I am going to zoom in some by pressing Command+. So here we have our image, and notice we have
all these bright, bright yellow areas here; it is an RGB image in 8-bit mode. I want you to keep focused on these yellow
areas here because as we start Soft Proofing, we are going to see a change. But before we do, let’s take a look under
the View menu. You will notice under the View menu, we have
Proof Setup, Proof Colors and Gamut Warning. What these things can do here is allow us
to preview how the image is going to look using the Color Settings
that we applied in the Color Settings dialog box. Before we go ahead and Soft Proof, let’s say
that this image is ready to go, we are ready to output this image,
and we want to convert it to profile, meaning convert it to CMYK, in order to print it in
a four color process job. One way to do that, and probably the best
way to do that is to choose Edit, Convert to Profile. In this dialog box here, Photoshop is saying
the current profile that is applied to the image is the Adobe RGB Profile,
which is a good profile, it’s actually the widest gamut of the RGB profiles available. The Destination Space, which is what we are
going to convert to, is currently set to the Working CMYK option,
which we chose in Color Settings, in the Color Settings dialog box, which is U.S. Web Coated
(SWOP) v2, which is a very common CMYK Color Profile. This is what most of your printers are going
to probably tell you to convert to. That’s all fine. That means that if we convert this guy, this
is going to be the new profile and that’s going to be applied. But let’s say we change our minds, we are
not ready to actually convert this guy yet. We want to make a couple of more changes before
we do, but we would like to see what’s going to happen when we do convert it. So rather than committing to this and clicking
OK, we are going to click Cancel and this is where Soft Proofing comes in,
because if you look under the View menu, where it says Proof Setup; it’s currently set to
Working CMYK, which is the same thing that we just saw in
the Convert to Profile dialog box. Working CMWK is set to U.S. Web Coated (SWOP)
v2 in our Color Settings dialog box. If we wanted to change that, we could choose
Custom and choose a different device to simulate from this menu. Let’s say our printer wanted us to choose
U.S. Sheetfed Coated or Sheetfed Uncoded, we could choose one of those here,
or we can even choose a different RGB profile, like sRGB, if we are designing for Web. For now I am going to keep it set to our Working
CMYK, which is U.S. Web Coated (SWOP) v2. You could change this and have different Soft
Proof settings set up here in this dialog box. I am going to click OK. We are going to stick with our current settings
and notice that as soon I clicked OK, it’s already previewing in the Soft Proofing
Mode. One way to toggle back and forth between the
modes is to press Command+Y or Ctrl+Y. Notice if you choose View, Proof Colors, it
says Command+Y or Ctrl+Y. I am going to choose it again to turn it off. Look in the yellow areas, see what’s happening. What’s happening is that yellow color is out
of gamut for the profiles that we have chosen. So if I press Command+Y again, this is what’s
going to happen to the color when we output it and covert it
to that CMYK profile, U.S. Web Coated (SWOP) v2. Once again, this is the source, this is the
destination, and that may not necessarily be a good thing, which means that we may want
to change a few things about our image before we actually do convert it,
so this is where Soft Proofing can be very, very helpful to you. Also, something you can do is choose View
Gamut Warning, that will actually highlight any areas that
are out of gamut in your entire image. So you can see all these different gray areas? That’s telling us that these are the areas
that are out of gamut. So this kind of stuff, Command+Shift+Y to
turn off, this kind of stuff is very, very helpful to us. It’s helpful to understand how we can use
these Color Settings in Soft Proofing with our images, even before we get real involved
with making our edits, because we can turn on that Proof Colors Mode and see what’s happening
as we make our edits, and than can be very, very useful to us and
save us a lot of time.
