Photoshop 2018 will not save a transparent .png with and attached sRGB profile. The Export Feature will allow it, but changes my 300ppi files to 72ppi. I have a workflow that requires saving transparent pngs at both high and low res, and they need to have a transparent background and an sRGB profile attached. Without the attached profile they do not display properly in Photoshop if set to a working space other than sRGB. I am now back to PS 2017 until I can find a solution or Adobe fixes 2018 to have pngs save sRGB file with profiles. Any thoughts from anyone on a workaround???
