Художественная техника офорта представляет собой гравюру на металле, для которой углубленные элементы печатной формы создаются путем травления металла кислотами. В дословном переводе с французского «L’eau-forte» означает «крепкая вода» — так раньше называлась азотная кислота, употребляемая для травления металла.
Процесс создания офорта довольно длительный и сложный. На цинковую или медную пластину наносят кислотоупорный лак. Офортной иглой или другим инструментом процарапывают слой лака по линиям будущего изображения до металла, после чего пластину помещают в травящий раствор.
Травление можно производить в несколько приемов. После первого травления в местах, где лак отсутствовал, образуются незначительные углубления. Затем места, которые соответствуют светлым участкам изображения, вновь покрывают лаком и вторично подвергают травлению, углубляя печатающие элементы. Таким образом, за несколько травлений получают желаемую градацию тонов. Для печати краска закатывается в углубления, ее избыток снимается с ровной поверхности; под действием давления краска переходит на бумагу. В случае необходимости рисунок дополняют повторным травлением или механическим гравированием.
Чаще всего офорт делается в черно-белых тонах, реже – в цвете. В итоге получается своеобразная и интересная картина, которую повторить практически невозможно (если только нет оригинала доски, с которой делается оттиск).
