Photoshop Soft Proof Settings for Paper Profiles

Soft-proofing in Adobe Photoshop allows photographers and printmakers to preview on-screen how an image will look when printed on a specific printer and paper combination. By configuring the correct Proof Setup options using ICC profiles, Photoshop accurately simulates color shifts, tonal compression, and paper brightness. This guide explains the exact settings required in Photoshop's Customize Proof Condition dialog to simulate target printer paper profiles effectively.

To configure soft-proofing, navigate to View > Proof Setup > Custom to open the Customize Proof Condition dialog box. The following settings are required:

1. Device to Simulate

Select the specific ICC profile created for your exact printer, ink set, and paper stock (for example, Epson P900 Premium Luster). Do not select a generic working space like sRGB or Adobe RGB (1998), as this defeats the purpose of simulating a specific substrate.

2. Preserve RGB Numbers

Ensure this box is unchecked. Checking this box forces Photoshop to display how colors appear without converting them to the printer’s color space, which is only used to see how an image looks if sent to a device without color management. Leaving it unchecked enables the proper color conversion simulation.

3. Rendering Intent

Choose between Relative Colorimetric and Perceptual:

• Relative Colorimetric: Preserves all in-gamut colors exactly and shifts only out-of-gamut colors to the closest reproducible hue. This is the standard choice for most photographic prints.
• Perceptual: Compresses the entire tonal range of the image to fit inside the printer’s gamut, maintaining visual relationships between colors at the expense of absolute accuracy. Use this if the image contains severe out-of-gamut gradients.

4. Black Point Compensation

Enable Black Point Compensation (BPC) by checking the box. This maps the darkest black of the image to the darkest black the printer and paper can physically produce, preventing shadows from plugging up or clipping completely.

5. Display Options (Simulate Paper Color and Black Ink)

These two checkboxes are critical for true paper simulation:

• Simulate Paper Color: Checking this box adjusts the on-screen white point to match the physical base tint and brightness of the paper. Bright white glossy papers will look different than warm-toned, unbleached cotton rag papers.
• Simulate Black Ink: This automatically activates when "Simulate Paper Color" is selected. It simulates the dynamic range (Dmax) of the paper, softening deep blacks to reflect how light absorbs into real ink and paper rather than the bright, backlit display of a monitor.

Once configured, click OK to apply the soft proof, or click Save to store the profile preset for future use. You can toggle the soft-proof preview on and off at any time using the keyboard shortcut Ctrl + Y (Windows) or Cmd + Y (macOS).
