 \section{Halftoning algorithms}
 
 The most ancient halftoning method is probably classical screening. This highly
-parallelisible algorithm consists in tiling a dither matrix over the image
+parallelisable algorithm consists in tiling a dither matrix over the image
 and using its elements as threshold values. Classical screening is known for
 its structural artifacts such as the cross-hatch patterns caused by Bayer
 ordered dither matrices \cite{bayer}. However, modern techniques such as the
