Embedded Profile Mismatch prompt appears inconsistently across team workstations

Standardize on Convert to Working RGB with the prompt disabled

For most web and mixed workflows, set every workstation to Convert to Working RGB and uncheck Ask When Opening: Profile Mismatches. This forces Photoshop to convert every incoming image to the team’s chosen working space (for example, sRGB IEC61966-2.1) automatically. No dialog appears, so behavior is identical on every machine that shares the setting.

Likely explanation versus confirmed facts

Likely explanation: The prompt appears on some machines because their Color Settings differ—either a different RGB policy is selected or the Ask When Opening checkbox is still enabled. Photoshop does not enforce a global default; each workstation stores its own policy.

Confirmed facts: The Ask When Opening: Profile Mismatches checkbox gates the per-document prompt. When it is unchecked, Photoshop applies the selected policy silently. When it is checked, the user sees the dialog and can override the policy per file. The policy choices are Convert to Working RGB, Preserve Embedded Profiles, and Off.

Steps to standardize

1. On a reference workstation, open Edit > Color Settings.
2. Set the RGB working space to the agreed standard (e.g., sRGB IEC61966-2.1).
3. Set RGB Color Management Policy to Convert to Working RGB.
4. Uncheck Ask When Opening: Profile Mismatches.
5. Save the configuration: Edit > Color Settings > Save and export a .csf file.
6. Import that .csf on every other workstation.

Validate before deployment

Open a test image with a known embedded profile—an sRGB gray ramp or a Lab reference patch works well. Use the Info panel to read the resulting RGB values. They should match the expected conversion into your working space. Repeat on two or three workstations to confirm the numbers are identical and no dialog appears.

Check	Expected result
Open sRGB test image	No dialog; values match working-space conversion
Open Adobe RGB test image	No dialog; values match working-space conversion
Open ProPhoto RGB test image	No dialog; values match working-space conversion

Paste Profile Mismatch

Yes, extend the same principle to compositing. Disable the analogous paste prompt so pasted layers follow the same automatic policy instead of interrupting the user. The exact label may vary by Photoshop version; look under Edit > Color Settings for a paste-related “Ask When” option and uncheck it after importing the .csf.

When the recommendation changes

If your downstream pipeline is exclusively print handoff or archival and you must preserve original embedded profiles for soft-proofing, switch the policy to Preserve Embedded Profiles and keep the prompt disabled. That keeps original numbers but may render differently across open documents. If your pipeline is exclusively print archival, confirm that—it changes the recommendation.
