Final answer:
Typographic letters are made legible not only by their forms and by the color of the ink that prints them but also by the spacing between the letters and words.
Step-by-step explanation:
Typographic letters are made legible not only by their forms and by the color of the ink that prints them but also by the spacing between the letters and words, known as letter and word spacing.
Letter spacing refers to the space between individual letters in a word, while word spacing refers to the space between words in a sentence or paragraph. Proper letter and word spacing helps improve readability and comprehension of the text.
