Lovely stuff, but halftone prints are just one type of prints. Before digital printing was a thing, photos were created using enlargers throwing light through a negative on photosensitive paper. Since the negative was also created using photochemical effects, the "frequency" effect was much reduced. This can still be done by ordering prints in "photographic papers" by Fuji or Kodak. If the image was created using a digital sensor, then it won't work as well, of course because the sensor itself is subject to a grid. However, the kind of Bayer Filter used in the sensor can help tackle the effect at source. This is what Fuji's X-Trans sensor[1] claims to do. (I am a Fuji user but I have no data point to offer in either direction) [1] https://en.m.wikipedia.org/wiki/Fujifilm_X-Trans_sensor https://en.m.wikipedia.org/wiki/Fujifilm_X-Trans_sensor
