Abstract

In the manufacture and assembly of printing heads, sometimes a skew condition may prevail, normally as a result of cumulative tolerances. This skew condition is characterized by the printed characters being skewed or slanted (either to the left or right) from vertical. While this condition may not be noticeable with a small amount of skew, such as 2o-2.5o in normal printing, nevertheless it becomes noticeable even with this small amount skew when printing characters in the graphics mode such as forming interconnecting vertical lines, and the lines formed appear to have what is known as a venetian blind effect.
