It looks like a limitation of the scanner. Have you thought of using a camera on a tripod to make copies of the original photos? You are scanning at 600dpi, but a decent camera should be able to exceed that easily if the originals are no larger than a postcard (150mm x 100mm). Just make sure the photos are evenly illuminated and set the camera colour balance accordingly.

Start by checking to see if the scanner driver has an option to compensate for different paper types. It looks as if the sensor is reflecting off the paper. I haven't experienced this, but i probably have a different scanner. -- Liam Quin - https://www.fromoldbooks.org/ Fullt-time slave in voluntary servitude. ___ gimp-user-list mailing list List address:gimp-user-list@gnome.org List membership: https://mail.gnome.org/mailman/listinfo/gimp-user-list List archives: https://mail.gnome.org/archives/gimp-user-list
Re: [Gimp-user] scan-mirrage-effect-Problem with postcard
Well, it's not moiré from the glass. It seems to be a scanning artefact introduced by the scanner. But you say it doesn't happen with scans of images on plain or matte paper. try putting a black card over the postcard before you lower the lid. Also check your scanner settings. If that doesn't work, you could try photographing the glossy postcard with a camera. With some fridge magnets you could stick it vertically to the side of something metallic in good light, like your refrigerator or your car. Then crop out or clone out the magnets from the photograph.
