// Plates for CMYK and a spot; an RGB photo converts through FOGRA39, the logo prints on its own plate.
Egami.Colors.InkSet inks = Egami.Colors.InkSet.FromProfile(Egami.Colors.ColorProfile.Fogra39)
    .WithSpot("PANTONE 186 C", Egami.Colors.InkAppearance.Cmyk(0, 1, 0.81f, 0.04f));
using InkRaster page = new(inks, 300, 200);
using (InkCanvas canvas = new(page))
{
    canvas.Clear(Egami.Colors.InkColor.None);                                   // paper
    canvas.FillRect(new RectF(0, 0, 300, 120), new Rgba8(80, 140, 200, 255));   // RGB: converted to CMYK
    canvas.FillCircle(new Vector2(150, 100), 40, new SolidPaint(Egami.Colors.InkColor.Spot(inks[4], 1)));
