I have a scanned-in picture, that I think was originally printed on paper that had a texture. I suppose it was okay as a print, but it makes it hard to GIMP it. Is there a way to smooth out the pattern?
Here is a sample at 200% zoom.
Hi,
Spontanously I’d say FFT or similar.
Wait a sec and I’ll try to scout up a link…
How about this? remove print pattern
Have fun!

Hello, to remove dot patterns in scans from printed materials, I use gmic’s descreen filter. Your canvas pattern is quite different, but you can give it a try at least.
A technique that can work is to
- Make one scan
- Rotate the picture 180° in the scanner and make a second scan
- Load the two scans in Gimp as layers,
- Rotate one of layers
- Align the layers
- Set the top layer to “lighten only”
However this requires a scanner with little distortion, or taking extract steps to compensate.
You might get it with a FFT plugin. Which OS ?
Always difficult to be certain with a scaled clip from original but it goes like this.

FFT was my thought and usual go-to for these types of patterns also. (
for the example @rich2005).
