Grayscale image has various RGB values and a color cast
Grayscale image has different RGB values
If a grayscale image in the color space RGB does not have identical color values, a color hue may occur in the image.
This can be corrected by adapting the image accordingly.
The color dropper can be used to check whether the image has identical RGB values, if they differ only slightly from one another, a coloring can occur.
Please follow these instructions:
First, convert the image to a grayscale image: In Photoshop: Edit >Convert to Profile...> Profile: Grayscale workspace space - Dot Gain 15% (settings see screenshot).
Since the files always have to be transmitted to us in the RGB color space, and not in the grayscale color space, the image must then be converted back into the RGB color space:
In Photoshop: Edit >Convert to Profile ...> Profile: RGB working space - sRGB IEC61966-2.1 (see screenshot for settings).
Now the RGB values are identical R 167 / G 167 / B 167 and the file has no color stitch and can now be ordered from us.
