The RomanMOD engraving font is the modern version of the Roman font family. It is called modern because of the form of the lower case letters.
The RomanMOD font is probably the most recognized font. It represents upper and lower case letters shaped as you learned in grade school. Because the lower case does have descenders this font is not the best choice where height is limited such as on the DK8 unless all upper case is used.
This font engraves well as all upper case or as mixed case.
