The most frequently asked question that I receive is "why don't
my prints match the screen?" Generally it's down to poor monitor
calibration, but on other occasions it's down to the fact that the user
has unrealistically high expectations of what can be printed or worse,
they have made the wrong selection in the Photoshop Print dialog.
This section will discuss the new features and commands introduced
with Photoshop 6 that should go some way to answering the above question.
There will be many colours that simply cannot be printed accurately on
an inkjet; the secret is to figure out before hand what they are. With
Photoshop 5 there wasn't any simple way to preview on-screen how an RGB
image would print to an inkjet printer, although a few workarounds have
been published. Photoshop 6 has addressed this issue with the new
Proof Setup and Proof Colors commands.
Basically soft proofing is nothing more than using your monitor as a
proofing device, however, accurate proofing is dependent upon the quality
of the monitor profile created as described in Part 1 and a profile for
the printer. Note that when I write of printer profiles I mean those for
specific media. In order that we may get Photoshop in a state ready for
soft proofing we must set it up. This is done via the View > Proof
Setup menu as shown below.
Although Proof Setup will only affects the current or "active"
image on your desktop, you MUST configure the proof setup via the
Custom menu option with NO image/document open. If you attempt to
configure Proof Setup with an image/document open then the existing
Photoshop default Soft Proof profile will be retained as the default.
Before explaining how to configure Proof Setup I hope you also notice
the three RGB options towards the middle of the drop-down menu.
You can actually use these to preview how your image will look on other
platforms, e.g. Mac or PC and on your own computer outside
of Photoshop using the Monitor RGB option. . The Monitor RGB
option is effectively the same as switching OFF the "Display Using
Monitor Compensation" checkbox in Photoshop 5. Assuming that you are
NOT using a VERY wide working space e.g. EktaSpace or Adobes
Wide Gamut RGB the Monitor RGB option also provides an effective method
of checking the quality of your monitor profile. If on selecting
Monitor RGB, the image turns very ugly you can take it as read that
the monitor profile is messed up. By ugly I mean significantly different,
large colour shifts. Not just a bit brighter, darker or flatter (e.g.
whites turn yellow).
The screen grab below shows a typical view of the Proof Setup
dialog for printer output simulation. From this dialog you can easily
select, configure and save your own customised soft proofing setup for
any number of different printer profiles. Remember, make sure you have
NO images/documents open when going through the process of defining
your own default Soft Proofing profile.
We begin the process by choosing the Profile; in the example shown
above I have selected the Epson profile for Photo Paper. This choice will
be the profile for the media that you want to simulate on the monitor.
Preserve Color Numbers
This option will only be available if the image and printer profiles
are in sync, i.e. both are RGB or both are CMYK. Selecting the
Preserve Color Numbers checkbox will usually result in a quite awful
looking display, this is how it should be.
One purpose of this option is to enable you to see how the image
would print if the media profile had not been selected in the Profile
pop-up menu. There are apparently others, but these all well beyond my
understanding. Normally it is best the leave the checkbox unchecked.
I described Intent previously when discussing the
Conversion Engines. Typically, it will be best to stick with
Relative Colorimetric or Perceptual when printing
photographic type images.
There are two options (or checkboxes) shown in this section of the
Proof Setup dialog. In theory, the first Paper White allows
you to simulate the colour of the paper white. The second Ink Black
will enable you to simulate how dark black will appear on the media you
are printing to. Note that selecting the Paper White checkbox
will cause the Ink Black to be selected and greyed out. The
resulting soft proof display can be quite disconcerting in that the
overall tone of the image may tend to look compressed or slightly colour
shifted. This may especially be the case when attempting to use scanner
based profiles to soft proof the Epson 870/1270/2000 series printers. In
such circumstances it may be best to ignore the use of the Paper
White and Ink Black since it is VERY unlikely that
they are in fact providing an accurate soft proof. No doubt things will
improve as the suppliers of the profiling software update their programs
to be compatible with this new Photoshop feature.
At first the new Print dialog in Photoshop 6 will appear a bit
more complex than its predecessor. It contains a few new options and has
(on the surface at least) omitted an option that caused considerable
confusion in Photoshop 5, namely the Printer Color Management
When Print is selected from the File menu a dialog
similar to that shown below should appear. You should check to see the
image Source Space and the Print Space: Profile. You will
NOT be able to change the Source Space, nor do you really
want too. The Source Space tells us which one of the Photoshop
Working Spaces the image is actually in. If you were to leave the
Print Space: Profile as Same as Source then the resulting
print is likely to be less than optimal.
following 4 examples show how to configure the Print dialog and
driver if using an Epson printer if using the Mac OS and
Example 1 - Epson Recommended Automatic
Settings (Mac OS)
The image should be in a Photoshop Working Space such as
ColorMatch, Adobe RGB (1998), BruceRGB, etc.
Photoshop 6 Print Dialog
- Choose the media type (I show Photo Paper).
- Select Printer Space Pop-up menu and choose "Printer
Color Management". This ensures that the correct profile for the
image is embedded into the image file and that the printer will carry
out the correct colour space conversions. Do Not leave
the profile set for "Same as Source"
- Choose Custom Mode.
- Select Advanced, the following dialog appears.
- In Color Management choose either of the options "Color
Controls, PhotoEnhanced or ColorSync".
- Select your preferred Print Quality setting.
