Photos & spot color

[Nivrams]

Can a grayscale photo be assigned a spot color. That is, can the photo be printed using a color other than black in a two color job, for instance?

I can't see a way to do this. There should be a way.

1) Open the photo in Affinity Photo.

2) Use the menu: Document > Color Format > RGB to change the photo from black and white to color (even though it will still display as black and white).

3) Add an Adjustment Layer

     a] Use Recolor to get a rather vivid color to substitute for black. Moderate the saturation of the color to tone it down a bit.

     b] Use a Lens Filter to get a somewhat more muted version.

     c] Use a Gradient Map (although this will potentially lead to more than one color being added, depending on the gradient chosen).

I am looking to print the grayscale photo in a color, one color, other than black or CMY (or RGB).

I believe your process involves adjusting the 3 primary colors for an effect. What I want to do is use a pantone color instead of black— and not have the printer change the ink on the black plate.

 

Probably will get this when we get duotones (or tri-tones.)

If you were working with a greyscale image on its own then I would have thought you could simply add a new layer above the image layer, set its blend mode to 'Screen' and flood-fill it with the Pantone colour that you want. However, in your OP you mentioned a two-colour job, so I don't think my suggestion would help unless you were working directly on the separations.
