Pencil Drawing By Paul Lung

Unlike wax-based coloured pencils, these can be easily erased. Their main use is in sketching, where the objective is to create an outline using the same colour that other media (such as wax pencils, or watercolour paints) would fill or when the objective is to scan the colour sketch. Some animators prefer erasable colour pencils as opposed to graphite pencils because they don't smudge as easily, and the different colours allow for better separation of objects in the sketch. Copy-editors find them useful too, as their markings stand out more than graphite but can be erased.
• Non-reproducing
or non-photo blue pencils make marks that are not reproduced by photocopiers (Sanford's Copy-not or Staedtler's Mars Non-photo) or by whiteprint copiers (Staedtler's Mars Non-Print).
