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).

These strengths are moderated, to varying degrees, by longstanding issues faced by all four banks (also characteristic of many other major domestic players), including large loan concentration, foreclosed properties with modest reserves, developing corporate governance standards, and the presence of families as controlling shareholders.
