2. Open the image. Accept the embedded color profile if there is one: Color Otherwise accept the default that Adobe Photoshop proposes: 3. Once you have defined the color space in which you are going to work, you can if you like make a soft proof, which means emulating on the screen how the image will look when printed. To do this, you will need an ICC profile for your monitor. Select View > Proof Setup > Custom. Use the following information to select options in the Proof Setup window. ● Profile: choose the profile based on the printer model and paper type you intend to use. ● Preserve Color Numbers: this checkbox tells the application how to simulate the document's appearance without converting colors from the Document Space to the Proof Profile Space. It simulates the color shifts that may occur when the document's color values are interpreted using the Proof Profile instead of the Document Profile. This option is not recommended. ● Intent: this menu allows you to choose a rendering intent for the conversion from document space to simulation space, letting you preview the effects of different renderings. See Set the rendering intent on page 69. ● Use Black Point Compensation: this option is recommended if you have chosen the Relative Colorimetric rendering intent. See Perform black point compensation on page 68. ● Paper White: this checkbox emulates the whiteness of the paper on the monitor. The effect is the same as using the Absolute Colorimetric rendering intent. ● Ink Black: this checkbox turns off the black point compensation for the rendering from simulation to the monitor. So, if the simulation space black is lighter than the monitor black, you will see the washed-out blacks on the monitor. This option is not recommended. ● Preview: if this checkbox is enabled (recommended), the changes you make in this window are reflected in the image immediately.

Once you have defined the color space in which you are going to work, you can if you like make a

. Use the
following information to select options in the Proof Setup window.
Profile
: choose the profile based on the printer model and paper type you intend to use.
Preserve Color Numbers
: this checkbox tells the application how to simulate the document's
appearance without converting colors from the Document Space to the Proof Profile Space.
It simulates the color shifts that may occur when the document's color values are interpreted
using the Proof Profile instead of the Document Profile. This option is not recommended.
Intent
: this menu allows you to choose a rendering intent for the conversion from document
space to simulation space, letting you preview the effects of different renderings. See
Set the
rendering intent
on page
69
.
Use Black Point Compensation
: this option is recommended if you have chosen the Relative
Colorimetric rendering intent. See
Perform black point compensation
on page
68
.
Paper White
: this checkbox emulates the whiteness of the paper on the monitor. The effect
is the same as using the Absolute Colorimetric rendering intent.
Ink Black
: this checkbox turns off the black point compensation for the rendering from
simulation to the monitor. So, if the simulation space black is lighter than the monitor black,
you will see the washed-out blacks on the monitor. This option is not recommended.
Preview
: if this checkbox is enabled (recommended), the changes you make in this window
are reflected in the image immediately.
