What does Baetens (2001) mean by ‘monstration’, ‘graphiation’ and the ‘graphiateur’?

Graphiation is defined as 'the narrative and graphic enunciation of the comics'. I believe this to mean that how the illustration is drawn also serves to depict the attitude and feel behind what is occuring, it is all very well to show a person hiding around a corner but graphiation would be the addition of darkness/shadows and from which point of view the illustration is drawn. Colours and shades are indicators, used by the author to show the emotion and mood of the scene which are not depicted simply by the expression of the characters face or body language and the graphiateur is the person who combines the written words with the images showing how the narrative is developing.

Monstration is the further development of the illustrations, in the sense that a single scene without words or description manages to depict the narrative, as Rizwana said it can be likened to a silent movie, in which the plot develops with images, without the words telling the audience what is going on.
