Tone Reproduction The contrast of an original must adjust during color reproduction to conform to the ranges of the halftone screens from 1% to 100%. It is virtually impossible to print densities more than 100% and tones less than 2 or 3 % will have no detail. This is one of the most difficult limitations of the printing process to understand or accept.
Toner A dry ink powder which has been electrically charged. Used in printers, fax machines and copiers. Generally, the image is translated into bit mapped charges of the opposite polarity on a special drum in the printer. The toner is attracted to the charged areas, where it is transferred to paper. The toner is then "set", usually by heat.
Track Kerning A method of uniformly increasing or decreasing the amount of letter and word spacing over a range of text, depending upon the specific font and size.
Tracking Adjusting the letterspacing uniformly throughout a selected portion of text. See kerning.
