This technique gives the most accurate copy of the engraved surface, even though it takes less information on the plastic sheets. Result are cheaper and faster to achieve without loss of resolution. Above all, this method solved the overlapping engravings problems found on the first panel of Vermelhosa site. The employment of these methods at the same site brought up important issues. The explanation given by these haven't always matched the expectations of local people and common visitors.
Some questions are yet to be answered.
There is, however, a need to make this finding understood and so admired by common visitors. Kolber's sketching, for example, can be very useful in panels and publications that show people an informal point of view, instead of giving them a complete archaeological tracing. This suggestion would help diminish frustrate tourists and potential vandals. Direct tracings have to be made for the sake of future studies. However, the truth they disclose is obviously recognised more immediately by researchers than by the general public.
