Weird textures from my digitize scan

Hey guys I am using the Kaiser light-box as my light source, the lomography scan mask and using the Canon Mk 4 with a old pentax macro lens and I am having troubles with my color negatives and B&W. I did so many exposure test, aperture test, letting a space between my negatives and my light source and I still getting these annoying textures… (I am not talking about the dust but the textures in the sky.)**.
I need help.

The diamond pattern that is visible in the sky is caused by the Kaiser light panel.

You can get rid of the pattern when you put 1-2 inches distance between the panel and the negative. Moreover, you might also try to add a diffusor. Search the forum for details.

Awesome, I’m gonna do some test today.
I appreciate your feedback thank you so much.
