Genesis of the stamp - [Etude monographique du 0,50F Marianne de Béquet]

Introduction

The process to produce an intaglio-printed stamp is the following: a draftsman (who may or may not be the engraver) generates an original design. After its acceptance by the French postal administration, the original design is photographically reproduced on a mid steel plate (generally of size 70 x 80 mm), in the exact size of the stamp and in reverse.

The French Stamp Printery (I.T.V.F. in French) supplies this plate to the engraver who uses the photography to produce the primary die by means of calibrated chisels. A chisel is a small square or elongated diamond-shaped steel bar with a wooden handle which allows to engrave intaglio all the elements of the representation by removing shavings. The engraver uses a stereo microscope to allow the relief perception of engraving. Intaglio printing gives nuances of grey according to the depth of grooves and the closeness between them.

The production of stage die proofs from the die requires the employment of a particular press, called hand press, made of a table maintained by wooden pillars and provided with a mobile tray placed between two wooden cylinders, the movement of which is given by a steering wheel activated by the printer.

The mid steel plate must be completely inked with a greasy and soft, but non liquid, ink. The printer pushes the ink into grooves with a tissue pad, the plate being put on a stove so that the ink is softened by heat. Then the printer wipes the ink on the surface of the plate, first with blades, then with the palm of his or her hand, leaving ink only in the grooves. Then, he or she puts the plate on the mobile tray of the press, engraving upward. He or she recovers it by a beforehand moistened sheet of paper to make it more ink-receptive. He or she arranges felt cloths over all these elements, and he or she activates the press. The tray moves up, and the plate takes place under the upper cylinder which puts pressure, forcing cloths to push the paper which fetches the ink in the bottom of grooves.

Stage die proofs

During the elaboration of his or her die, the artist generally produces several stage die proofs to verify his or her work and, possibly, to make modifications. These stage die proofs are printed in black, on some more or less thick stationery Bristol paper, directly by the very artist on his own hand press. It is necessary to note that the plate of mid steel leaves on paper an imprint called die sinkage.

Pierre Béquet printed two stage die proofs for the stamp Marianne de Béquet on his personal hand press:

One during the engraving process, showing the die in progress before the engraving of background:

The primary die

The primary die is visible at the French Postal Museum:

Artist’s die proofs

Artist’s die proofs were made in the French Stamp Printery, with uninked seals and marks; we can see below a red artist’s die proof and a black one (at least red, blue and black artist’s die proofs are known):

Hovering image: there are 5 test areas which, when rolled over with the mouse, appear pinkcoloured and trigger the occurence of an image specifying the content of the affected area. One can thus see:

the dry-printed mark Imprimerie des Timbres et Valeurs Fiduciaires (ITVF), on the bottom left;

a dry-printed mark with a head of Marianne, on upper left;

a dry-printed mark with the words IMPRIMERIE DES TIMBRES-POSTE – PARIS, on the right;

the watermark of the paper with the name of the paper supplier, upwards;

an enlargement of the signature of Pierre béquet, which shows that it is in the same condition as on the stage die proof, that is to say barely drafted, at the bottom left of the stamp.

According to the site Die Proofs by Giorgio Leccese and private information provided by a former printer, there should be between 21 and 23 artist’s die proofs produced since they are made under the control of the French Stamp Printery, in 1961 (21 if the designer is also the engraver, 23 otherwise). However, these figures were never officially confirmed. In addition, this number of artist’s die proofs is broken down as follows: 6 black proofs (or 8, if 23 are performed) and 3 proofs for each of the five other colors used, colors that are chosen by the printer performing the proofs. For the stamp 0,50F Marianne de béquet, I know artist’s die proofs in red, in black and in blue.

Color die proofs

The administration is used to produce colour die proofs before launching the printing of the sheets which will be marketed. For the stamp 0,50F Marianne de Béquet, eight colour die proofs are known. They were all printed on November 23, 1970, on the TD6-1 press. Here is a dated plate block of one of these printings:

Colours used to produce these colour die proofs are handwritten in the margin of the sheet: we so find, from left to right, BBR4SA (one BROWN colour), MBL5SA (one BLUE colour) and HRO5SA (one RED colour). The first letter of each package indicates the inkwell containing the corresponding colour ink (B for the bottom inkwell, M for the in the middle inkwell and H for the top inkwell). Finally, the last two letters (SA) of each package are the initials of SICPA, the manufacturer of the used ink.

Cancelled sheets

To end this overview on the genesis of the stamp 0,50F Marianne de Béquet, I would like to show the other end of the line: a plate block dated June 18, 1974 and cancelled for disposal by means of a roulette of grid.
