What are some differences between screen and traditional typography? How do these differences impact legibility and readability issues?

Question

What will be an ideal response?

Answer 1

Monitors have a resolution of 72 to 96 pixels per square inch thus it is difficult to make type look good on-screen and make type legible.
Computer monitors display type and images by lighting up various combinations of pixels. While readers focus their eyes on paper with markings in traditional typography, in a digital environment, readers focus their eyes on a screen that is emitting light waves. Because a lit screen is much more tiring for the eyes, providing adequate negative space around text becomes vital to both legibility and readability.
Because of the limitations of screen technology, only simplified versions of letterforms can be displayed on the computer's monitor.
Colors will look differently from how they appear on-screen when printed, and will vary from monitor to monitor depending on calibration.
Digital type set in a light gray value and set against a black background is the most readable combination for viewers, while printed type set in black on a white background is the most readable combination for viewers.
Italic letterforms tend to be difficult to read on-screen because the diagonals tend to look like steps of pixels.
