infill color spreading
Hi,
I'm trying to print a logo on my Prusa XL and the colors are "spreading" for lack of a better term.
I assume it's for stability/strength reasons, I noticed it was happening with other multicolor prints and it's typically not an issue, but my logo being mostly white, these infills are visible through the white portions of the print.
I tried adding some bottom solid layers with a modifier box, I figured if I had a few layers of solid white before the spreading it wouldn't be visible, but it starts as early as the 2nd layers and just grows from there.
What's causing this? Is there a way to turn off that setting? Or is it something I'm not understanding with the modifiers?
Thanks in advance!

Cheerio,
A couple of general comments first:
Some filaments, including some white ones, are semi-translucent and switching to one with a higher pigment density might be the simplest fix.
Your logo appears to have been converted from a 2D image without redrawing for the lower resolution medium. There are several flecks of colour that are far too small to print with the 0.4mm nozzles you are using - assume your smallest 'pixel' is one default extrusion width across at 0.45mm. The slicer still accounts for the space they should have taken even though they are unprintable.
OK, specifics:
Did you notice the warning triangles next to the parts list in the plater? They indicate corrupt files, usually, as in this case, 'open edges' where the surface triangulation is incomplete. In many cases the slicer can 'fix' the problem; the fix is to close the gaps but the slicer has to guess which edge to join to which and can often guess wrongly - go back to the original CAD and simplify.
Your colours go far deeper than necessary meaning the printer will change tools many more times giving more chances for errors and taking more time. For most purposes two layers deep is enough so in this case 0.4mm; one tenth of the 4mm you are generally using.
You have used multimaterial painting so every color is set as a seperate part - nothing intrinsically wrong with this but it's a huge chore with a complex design. If you group each colour in CAD then you will only have to set 5 colours.
Cheerio,
