Text-moire' minimization
First Claim
1. A typesetting system, for preparing text as pixel patterns with minimized text-moire′
- effects, comprisinga) input means to develop a text portion having lines of text aggregating visually readable patterns having words and inter-word spaces subject to text-moire′
effects;
b) text accumulator means, responsive to said input means, to store a plurality of lines of text and inter-word spaces;
c) moire′
-effect detection means to review the content of said text accumulator means, to develop a virtual moire′
prediction pattern;
d)control means inter-relating said input means, said text accumulator means and said moire′
-effect detection means;
e) text manipulation means, responsive to said moire′
-detection means and said control means, to alter the pixel patterns of individual characters and individual inter-word spaces in said virtual moire′
prediction pattern to minimize undesirable text-moire′
effects; and
f) output means responsive to said control means, said text accumulator means and said text manipulation means, to present as a visually-readable pattern a text closely-related to said preliminary text having minimized text-moire′
effects.

Abstract
Pixel-level monitoring and reconfiguring of both text inter-word spacing and individual character widths minimizes undesirable moire′ channels and moire′-glyphs, and more particularly relates to operator-selected automatic intra-word space manipulation and automatic intra-character width manipulation to achieve a pleasing overall page effect with maximized freedom from moire′-maze and moire′-glyph visual effects, both in proportional spaced fonts and fixed-character-width fonts. Selective scrolling may be by black-spot instead of actual characters, to make the white moire′-effects stand out more clearly. The typesetter may alternate positive and negative, which is another way to emphasize the moire′-effects. A further sub-variant, called “blush,” causes graying of spaces which are so surrounded by characters that they cannot participate in moire′-effects. This emphasizes the actual moiré-effects. The typesetter may “unselect,” by pointing a cursor at a moire′-effect and key + or − to accept the particular moire′-effect as benign, or to proceed with an amelioration procedure.
