Litho-litho-etch
WebLithografie is een zogenaamde vlakdruktechniek. Het woord is afgeleid van de Griekse woorden λίθος (lithos – steen) en γράφειν (grafein – tekenen/schrijven). Bij lithografie wordt de steen niet ingekerfd, bekrast of gesneden zoals in bijvoorbeeld een houtsnede, maar deze techniek maakt gebruik van de chemische eigenschappen van olie en water.
