Text on computer screens are either shown black and white for optimal contrast and legibility, or with gray-scale for a more smooth look. Non-gray text often result in too high contrast, where diagonal features of character look jagged. Gray text at small sizes on the other hand may smooth out text to such a degree that the text looks too fuzzy and becomes hard to read. Both the fuzzyness and the jaggedness are attributes of text that people may have personal preferences for. On a GlyphGate server you can control whether text should be smooth or crisp (i.e. gray, or black and white), as well as whether the text should be hinted or not.

Another aspect of text quality is that of font size. The height of a line of lower case Latin letter varies between fonts at the same font size. For example, 12 pt Verdana look much bigger than 12 pt Times New Roman. This causes problems when replacing fonts, as the text tend to grow and shrink with the used font. GlyphGate will let you compensate for these differences, thus enabling web authors to swap one font for another without having to go through web pages and change the font size as well. This is demonstrated below with the fonts Verdana and Century:
