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).

Prosecutors said Marshall, a former Broadway producer and diplomat, had exploited his mother's deteriorating mental state after she was diagnosed with Alzheimer's disease to pilfer expensive artwork off her walls, go on a spending spree with her money and make changes to her will that gave him control of her fortune, some of which Astor had wanted to bequeath to her favorite charities.

She was the first politician to realize that if you talk about the economy in terms of a shopping list rather than droning on about interest versus inflation, voters listen – or at least they did when it was still fresh and original to do so. But the narrow window of opportunity to target “Worcester Woman” (the charming 1997 term for a professional woman worried about social issues), without patronising everybody in a 100 mile radius, closed with the fall of Blair.

Morgan 17.11.2020 01:51 Looking for a job atorvastatin ca 40 mg PT's own dividend cut (reducing the commitment for the next two years to EUR0.10 per share from EUR0.325), provides some offset, and signals management's deference to bondholder interests. However, in Fitch's view it will be insufficient to stop the company's leverage (measured as net debt to EBITDA (both excluding Brazil) plus associate dividends) trending above 3.0x; a level the agency has previously stated as a key downgrade sensitivity. PT continues to manage its domestic business effectively. However, Fitch expects domestic EBITDA to decline by mid-to-high single digits in 2013 given the correlated effects of the economy. Liquidity is strong, with the EUR1.0bn seven-year Eurobond issued in April proving good market access, and ensuring the company is pre-financed through 2016.

Then, I have people take it every 45 minutes to an hour; that will help you keep your blood sugar levels up in the workable range during the race.â

More channels will be added both this year and in the next in the form of local offerings, as well as additional content, though the number wasn’t specified, nor were the amount of subscribers taking advantage of the service.

When this chemical differentiation occurs on a small planetesimal, the planetesimal does not have enough gravity to hold on to its atmosphere, so it escapes into space. Earth is very depleted in volatile elements compared to the average composition of the Solar System, likely because it formed from differentiated planetesimals that had already lost their atmospheres.

It also puts it in serious performance territory, just behind the Renaultsport Mégane R26.R that previously held the front-drive record and ahead of the six-cylinder E46-gen BMW M3 that was born there.
