Inky frame pixelation

I’d be really interested in hearing about people’s experiences with the inky frame (7.3” specifically) and displaying PNG images.
I’ve tried to design an image that renders some text and images with similar colours possible with the display. That’s going well with some experimentation, but the real issue is that even with using a pretty bold pixel font, I’m getting really bad dithering and it’s messing the readability of the screen up.

I don’t want to render the text using the helpers because there’s too much text to match up to locations on the screen where I’ve got image displayed.

The best thing you can do is to deactivate dithering and do it yourself instead. So the workflow would be: png → dithered bmp → add text → display without dithering.
