Holes in top layer show lower levels' different color
The black is Prusa PETG V0 and the FDE is Atomic PETG. Using all default values in PrusaSlicer 2.9.0. Layers are 0.15mm Structural. Infill is 100%. The letting "I", for reference, is 1.4mm wide.
Any suggestions on getting rid of the holes in the text that allow for the lower black to show though?
Thanks! - Jim

Additional information: it prints substantially the same on my Prusa MK3S using PrusaSlicer defaults, 0.15mm, 100% infill.

The problem is that the slicer tries to fill the area between the perimeters but the combination of extrusion width and varying distances between the perimeters across the letters doesn't give it enough space to work with.
A few things you try, in order of increased likelihood of success:
* Different font size
* Modified extrusion width, e.g., 0.3mm for perimeters and infill. Of course you should use a height range modifier to adjust it only in the region of the text.
* Smaller nozzle, e.g., 0.25 mm nozzle, which gives you greater horizontal resolution
PETG in general will give you inferior results, compared to PLA.

You appear to be printing just one layer of text on top of a flat surface. For a more even appearence print a few layers deep so the underlying filament is the same colour.
Attached is a demonstration of the technique with from 0 to 4 underlying layers: unzip, load both files together as parts and allocate to different extruders.
The file is intended for 0.2mm layers.
Cheerio,
