Stefan,
Can't give you any real answer. But yes the dithering is different on each channel.
They are all designed to avoid patterns and moire.

In response to a private answer:Thanks for the suggestion.I wish it was newton rings, I could solve it.But those artefacts have a chevron-patterned aspect and can be observed on a light table.I tested different channels combinations (same ink dilution in each), and it really looks like cutting down LC and LM (and rising other channels) makes great improvements, campaigning for a sort of conflict between X and LX channels if used equally.This might not sound that much related to QTR, but I remember a discussion where it was stated that QTR uses its own dithering algorithms and that every channel has its own dithering placement of drops, contradicting a moiré possibility.I hoped to get a deeper understanding of eventual dithering patterns interactions.Moving on anyway…Stefan Christiansen
