Running into an issue on an A1 Mini/AMS Lite multicolor print using Slate Gray BB Sparkle PLA/Hatchbox PLA in neon green. With flushing accounting for 40% of the total filament used, it’s incredible that I can’t get a clean result! Already using flow calibration, slowed everything down, and have tried face down, face up with supports, sideways, but regardless the dark haze around the text persists. Do I need to increase the flush volume even further? Is it possible that it’s flushing too frequently as well? Do I need to cease this folly and just switch to PLA Galaxy (no gray 
) ? Ironing on the second print also made quality worse somehow.
How are you creating that text in your model? How many layers thick is it? Reason I ask is it looks a little rough.
People here have noticed that under some circumstances there can be residues on a print plate that pick up and transfer to the next print. Do you get a clean print printing the part without the text/logo?
Color printing filament order can also fix or cause issues.

Clean the build-plate, you may have residue left over.
The order that the filaments print is very important.
Dark should always follow light colours.
Use the cog on the build plate (not the right) and change the order the filaments are printed, change both the first layer and subsequent ones.
Move the green before the black.
This can really improve things when printing face down, which is my preference for these sorts of things.
If dark prints first, residue can contaminate the subsequent colours.

You do not have “Flush into infill enabled” by any chance? And what absolute flush volumes do you use? A lot is a rather relative term so we can’t really compare.
Some filament can behave worse than others…
I mean this in terms of failing to get a CLEAN nozzle and sock after a filament change and in terms of NOT causing artefacts like stringing or extruding a bit over perimeters…
While the rough PEI plate offers great adhesion I find it less suitable to those detailed and important first two layers…
The benefit of invisible lines does not always make up for the problem coming with a rough surface.
As other pointed out the print order IS important if you want to avoid colour bleeding and ghosting effects.
Same for a good enough flush and clean wipe of the nozzle.
Could you provide a pic showing how the first layer looks when printed?
Like one with just the first colour and one showing the result once the layer is complete ?
