The pictures from SlashNet are SVG Data which is a vectorgraphical format. All the printing company uses this format because it is scalable to almost any size. Before printing it will be rasterzed to dots. So the inkjet printer can put small dots on the paper.
The rasterisation is one way process, a rasterized image cannot be converted to vector, that's why scanning a printed image does not help to reprint it.
The only way to get back the original vectorgraphical picture is, to redraw it.
The other problem is, that the resterized dots (made by inkjet printer) are placed in a random pattern. Every color placed in a different place (the 3 main color i mean) so a high resolution scan would show a lot of dots on a screen, which has to be blurred first.
I am telling this informations, because someone threw up the idea to reproduce original box of the EP.
