Color management

The color and tonal information in a digital document is stored as numbers. When we share these documents between devices, the device has to work out how to display the color. As not all devices can display the same color gamut it can lead to colors looking different on each device.

Color profiles

Documents without color profiles (or with unsupported color profiles) may not look the same across each device.

To ensure that the color looks the same on each device, we use color profiles to tell the device how to display or render the color information.

Color profiles

Documents with the correct profile for a calibrated device should closely match.

In Affinity Designer, an opened file's color profile is honored by default. You have the option to convert it to the current working color space. When placing images into an existing document, the image's embedded color profile will always be converted to the document's current working space.

On export, you can choose to embed the document's or a named color profile to ensure accurate color management. Alternatively, the exported file can be unprofiled by not embedding the document or named profile.

Assigning color profiles

Affinity Designer lets you choose global default color profiles, assign a color profile as you create a document, or at any point during your session.

To select default global color profiles:
To select a new document's color profile:
To convert the color space of file to be opened to the current working space:

Options exist to warn that a file's working space will be converted, or that an unprofiled file will be assigned the current working space's profile.

Move Tool To change your document's color profile at any time:
  1. From the File menu, select Document Setup.
  2. From the dialog:
    • Select the Color tab.
    • From the Color Profile pop-up menu, select a profile.
    • Select Assign or Convert.
      Assign adopts the new profile but leaves the values of the colors/pixels as is. Convert converts each color from the old profile to the new one—color/pixel values may change as a result.
    • Click OK.
To embed a color profile on file export:
  1. With Export Persona active, choose your Preset in the Export Options panel.
  2. (Optional) Select a different ICC profile from the pop-up menu. Otherwise, the document's color profile will be embedded.
  3. Check Embed ICC profile.

About soft proofing

Soft proofing simulates output as you design with respect to the color profile and the paper medium you intend to print on.

In Affinity Designer, this can be done by applying a Soft Proof adjustment to your design. You can then preview how your output will appear, preventing any nasty surprises at print time.

Because soft proofing is applied as an adjustment you can apply multiple adjustments, and therefore produce soft proofs for multiple output devices.

As an example, if you want to create several different output types, you might want to start with a color profile on document creation with a wide gamut (e.g., Adobe RGB 1998), and then change the profile to match the output destination. However, color information may be thrown away if changing to a smaller color gamut—simply changing back to a profile with a wider gamut will not restore the additional color information. By applying a soft proof adjustment you prevent this, allowing you to work in a wider gamut until you are ready to change to your chosen output profile.
