What You See on Screen Is Not What You'll Get in Print — Unless You Proof It.
Monitors display colors your printer or output device can't reproduce. Soft proofing simulates the output device so you can make corrections before printing a single sheet.

Soft Proofing for Print
Load your printer's ICC profile. See exactly which colors will shift or be lost on paper. Correct before you print.
🖥️
Soft Proofing for Screen
Proof to sRGB for web or Display P3 for modern mobile. Ensure color consistency across output devices.
💡Monitors display colors your printer or screen can't reproduce. Soft proofing simulates the output device so you can make corrections before you print a single sheet.
The Concept
What Soft Proofing Is
Soft proofing simulates how an image will look when output to a specific device — a printer, a paper type, or a display. It remaps the image colors to show only what that device can reproduce.
The Problem
Your monitor can display a wide range of colors (gamut). Most printers can only reproduce a smaller subset of those colors. Without proofing, you won't know which colors will shift until after you've printed.
The Solution
Soft proofing loads the output device's color profile and shows you the image as it will appear on that device. Out-of-gamut colors are visible so you can correct them before committing to ink or paper.
Analogy: Soft proofing is a rehearsal before the performance. You see the full show — including any problems — before the curtain goes up on the real thing.
Activation
Enabling Soft Proof
Soft proofing lives in the Develop module. Enable it and the display immediately simulates your output device.
1
Press S in Develop — or check the Soft Proofing box in the toolbar
The toolbar below the image (View > Show Toolbar if hidden). One keystroke toggles proofing on or off.
2
The image background turns white
Simulating paper white — the actual ground color you'll be printing on. A "Proof" badge appears in the Histogram panel header.
3
Profile and Intent controls appear in the toolbar
Use these to choose which device to simulate and how out-of-gamut colors are handled.
4
Compare: click the image to toggle the before/after
Clicking the image switches between proof view and normal view so you can see exactly what changes when proofing is applied.
Profile Selection
Choosing a Profile
The Profile dropdown in the soft proof toolbar selects which output device you're simulating. The right profile makes all the difference.
sRGB IEC61966-2.1
General web and screen proofing. Use when preparing images for client web galleries or digital delivery.
AdobeRGB
Professional screen and print proofing. Wider gamut than sRGB — used by professional print labs.
Printer ICC Profiles
Specific paper/printer combinations — e.g., "Epson_Premium_Glossy_2880". Download from your paper manufacturer's website.
1
Download the ICC profile for your specific paper/printer
Check the paper manufacturer's website (Epson, Ilford, Hahnemühle, etc.) — profiles are free downloads.
2
Install at the OS level (Mac: Library/ColorSync/Profiles)
Double-click the .icc file to install. Restart Lightroom if it was open.
3
The profile appears in LR's soft proof Profile dropdown
Select it and the soft proof instantly simulates that paper/printer combination.
Color Handling
Rendering Intent
Rendering intent controls how out-of-gamut colors are handled when the image is mapped to the output device's smaller color space.
Perceptual
Compresses the entire color gamut to fit the output. All colors shift proportionally — relationships between colors are preserved. Best for photographs with out-of-gamut colors throughout.
Relative Colorimetric
Only clips colors that are out of gamut, leaving in-gamut colors completely unchanged. Best for images with mostly in-gamut colors and only a few problem areas.
Recommendation: Use Perceptual for most photographs. Relative Colorimetric is useful when you have a largely in-gamut image and want to preserve those accurate colors exactly.
Finding Problem Colors
Gamut Warning
The Gamut Warning highlights every color the printer cannot reproduce — shown as a gray overlay on the image.
1
Press Shift+S or click the triangle icon in the soft proof toolbar
Out-of-gamut areas appear as a gray overlay on top of the image.
2
Identify which colors are causing problems
Reds, oranges, and cyans are the most common out-of-gamut colors in photographs. Vivid skies and saturated foliage also cause issues.
3
The goal: eliminate the gray overlay in important subject areas
Background sky gamut warnings are less critical than warnings on skin tones or the main subject.
Some out-of-gamut colors in non-critical areas (distant sky, background foliage) are acceptable. Focus your corrections on the main subject.
The Professional Approach
Making a Proof Copy
When you enable soft proofing, Lightroom asks if you want to create a Proof Copy — a Virtual Copy specifically for print corrections. This is the right answer.
Click "Create Proof Copy"
LR creates a Virtual Copy labeled "Proof 1". The original master image is completely untouched. Edit the proof copy freely — reduce saturation, shift hues, adjust tone.
One Master → Multiple Outputs
Original = your screen/web delivery version. Proof Copy = your print-corrected version. Both live in your catalog as separate virtual copies.
The Proof Copy is Labeled
In the filmstrip, the proof copy has a distinctive badge. You can create multiple proof copies — one per paper type or printer profile.
Proof Copy Editing
Correcting Out-of-Gamut Colors
Work on the Proof Copy with the Gamut Warning active. Watch the gray overlay disappear as you bring colors into the printable range.
1
Reduce Vibrance/Saturation globally
A modest reduction (–10 to –20 Vibrance) often clears most out-of-gamut areas without noticeably affecting the look.
2
Use HSL to target specific problem hues
Reds and oranges are most commonly out of gamut. Desaturate just those hues in the HSL panel — affects nothing else.
3
Slightly shift problem hue toward a printable neighbor
A +5 to +10 hue shift on reds toward orange, or on cyans toward blue, can move them into gamut with minimal visible change.
4
Adjust Highlights/Whites to recover blown highlights on paper
Paper has limited highlight range. Pulling back Whites by –20 to –40 on the proof copy recovers detail that would print as pure white.
Beyond Print
Soft Proofing for Screen
Soft proofing isn't only for print. You can proof for any color space or display profile — including web and mobile screen targets.
sRGB for Web
Proof with the sRGB profile to see how your image will look on standard sRGB monitors — the majority of screens used to view web content.
Display P3 for Modern Mobile
iPhones and modern iPads use a wider Display P3 gamut. If your clients view images on these devices, proofing to P3 shows the richer color they'll see.
For most photographers: sRGB soft proofing for web work is all you need. The print use case (with specific printer ICC profiles) is more specialized and matters most if you're doing gallery or lab printing.
Your Turn
Challenge + Recap
3-Part Challenge:
Enable soft proofing with the sRGB profile (press S) and compare the image to normal view — look for any visible color shift.
Turn on the Gamut Warning (Shift+S) and identify any out-of-gamut areas in the image.
Create a Proof Copy and make one correction — reduce Vibrance slightly and check if the gamut warning diminishes.
Soft Proof = Preview Output
Simulates any output device — printer, paper type, or display profile — before you commit.
Press S to Enable
In Develop module. Background turns white (paper). Proof badge appears in the Histogram.
Choose the Right Profile
sRGB for web, AdobeRGB for pro labs, specific ICC profiles for exact paper/printer combos.
Perceptual vs Relative
Perceptual for most photos. Relative Colorimetric when most colors are already in gamut.
