Abstract

Uma imagem varredura de meio-tom, adequada para renderizar uma imagem de tom contínuo, compreendendo vários pontos espiralados. Os ditos pontos espiralados compreendem (i) pixels de imagem dispostos como um primeiro arco (200) ou como vários arcos os quais juntos representam uma primeira espiral (100) e (ii) pixels que não são de imagem dispostos como um segundo arco (201) ou como vários arcos os quais juntos representam uma segunda espiral (101). Os pontos espiralados permitem uma dispersão controlada da tinta dentro do ponto, resultando em uma qualidade de imagem mais alta, economia de tinta e secagem mais rápida.
