Abstract
We investigate a method for combining two dis­
persed­dot halftoning masks for two colors that
generalizes the traditional angular displacement
used with clustered­dot halftone screens.
Our masks were two variations of the Linear
Pixel Shuffling algebraic mask algorithm involv­
ing numbers arising from two different third or­
der, Fibonacci­like recurrences, As an alternative
to screen rotation, these masks were repositioned
by flippng and rotating, and all pairwise posi­
tional combinations of the transposed, inverted
masks were used two at a time to generate cyan
and magenta images, each at nominal dot frac­
tions of 0.25. The resulting blue images were
