I want to resize a TIFF image to use as a target to test existing printer drivers with a new photo paper, prior to creating a printer profile. The test TIFF image I want to use has no assigned profile, i.e. not sRGB, Adobe 1998 etc. I wish to resize it in Affinity Photo then export it again as a TIFF image. As soon as it is loaded, Affinity adds "Assigned Profile (Adobe 1998)....to this unprofiled document".
My question is how can I export it without any colour enhancement being applied? Thanks for any help.
