OK! So after blogging about what I wanted to do next with the fonts, and looking at the results again, I decided to take one more step in the area of “polish” and put an extra pixel (or more, when needed) between the fonts, to reduce not only the crowding of the letters, but it also got rid of the artifacts!
Here were the 1.0 versions of my first attempt at fonts, including horrible artifacts:
After adding pixels, the same fonts looks much better, in the 2.0 version!
The text characters needed literally only 1 more pixel between them to remove the artifacts.
The numbers weren’t even even to begin with, so I had to play with the spacing on them to get them to line up even with the letters, but I now have at least letters and numbers to play with, and put on the screen!
