1. Drawings with lines which for any reason cannot be sent on a digital format (art. 7.1.2), should be sent on normal paper (neither vegetable nor acetate, etc.), of DIN-A4 or DIN-A3 size; numbered in pencil at the bottom of the page. If necessary, a graphic scale should be included. If coloured areas are incorporated, these should be shown with vegetable paper placed on top instead of sticking them to the drawing. The figureís caption should be placed on a separate sheet.
2. Photographs which are not sent in digital form can be sent in black and white or colour, on paper (not bigger than 20 x 30 cm.) or on slides. Printed material or material containing areas of very small dots should be avoided. For the captions, the information mentioned above should be followed.
