2. Open the image. Accept the embedded color profile if there is one:
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.
● Use Black Point Compensation: this option is recommended if you have chosen the
Relative Colorimetric rendering intent. See Perform black point compensation.
● 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.
