Brasil - Provas de Impressora


* In 1904 the Swiss company Winkler Fallert & Co., AG (WIFAG) was founded and in 1945 it produced its first rotary stamp printing press for the Swiss PTT. By the late 1970s, WIFAG was concentrating on newspaper presses and had ceased to install any further stamp printing presses. 
The dummy stamps were used as a part of the press commissioning process and it is understood that these would have first been printed in Switzerland at WIFAG prior to dismantling and shipping the press to the purchaser. It is also thought that the plates used in Switzerland were sent to the purchaser (probably with colour progressive sheets) to enable testing to be undertaken on site in an attempt at getting the printer to replicate the quality of the printing undertaken at WIFAG.

** KEY: The letter I = Intaglio (recess, steel engraving, line engraving), L = Letterpress (typography, surface printing) and P = Photogravure (gravure). Where a letter is repeated under the Press heading (say, IPPP) it signifies that the press had more than one of that type of printing unit in its configuration, thus enabling more than one colour to be printed in a single pass by the same printing process. IPPP would therefore indicate that the press had one intaglio and three photogravure printing units installed. Be aware that a press could print a particular dummy stamp in a different configuration (as noted under Units). This would mean that not all of the capability of the press might be in use (say, PPP only, thereby not utilising the intaglio element of the press in the example here).
