Valira Torrent - bulletin of the Andorran Philatelic Study Circle. Issue 12, pp5-7 (October 1980).
This article is based on a study entitled "Taille-Douce rotative" by P. de Lizeray, which appeared in the May 1980 issue of "L'Echo de la Timbrologie"; it deals with the marginal markings of recess printed stamps produced by the French Government Printing Works on rotary presses.
As the stamps issued by the French Post Office in Andorra are produced in these works, and some are specifically referred to in the article, it is hoped it will be of interest to our members.
On the sheets of rotary recess printed stamps one may find, depending on the period of printing and the type of press; six marks or numbers printed on the sheet margins:
The printing reference number has always existed since the beginning of the use of the rotary recess machines.
The printing date has also existed from the start, except that, after a time, it was not used for charity or commemorative issues.
The four other numbers or marks quoted above have undergone many variations over the years and the purpose of this article is to give precise chronological details of these changes.
The first printing on rotary recess machines was made on 22.3.29, the stamp being the 10f La Rochelle (all stamps referred to are issues of France unless otherwise stated). The sheets only bore two identifying marks, the printing reference number and the printing date. All the stamps were printed on "three colour machines" (machines which are able to produce stamps with up to three different colours, by a process of depositing different coloured inks on different parts of the printing plate).
A new reference number was added to the sheet markings, taking the form of "I C 2"; the letter "I" was always used, possible standing for "indicatif"; "C" referred to the press operator, and "2" the number of" the press. This reference number was printed in large fat figures and the first sheets of stamps to bear it were those for Andorra printed on 29.4.33, and for France of 20.6.33 (2f Arc de Triomphe). The reference number is known to have been used until 8.1.64.
No additional sheet markings but omission of printing dates for charity and commemorative issues. Last known date 17.7.41 for the 1f plus 1f France d'Outremer. This system remains unchanged to date.
No changes except the appearance of additional distinguishing marks for each of the three sheets produced by one cylinder revolution ..... 1, 2 or 3 dots ( ). The first sheets of stamps so marked were the 6f Andorre la Vieille of Andorra (19.7.45) and the 10f Marianne de Gandon of France (13.2.46). The system of dots continued in use until 1948.
The dot markings were replaced by a system of lines; 2 lines for sheet 1 ( || ), 1 line for sheet 2 ( | ), and no lines for sheet three ( ). This system was first seen on the 200f Airmail of France printed on 10.2.48, and continues to this day.
Markings unchanged but additional fancy "engine-turned pattern" printed on the previously blank stamp sized labels which appeared at the top and bottom, or sides, of the sheet according to the stamp format. This pattern was introduced to prevent stamps being forged on these blank, gummed, perforated stamp sized pieces of paper. The press number, and the operators identity reference is printed on top of one of these patterns, the sheet marking line(s) appearing alongside one of the patterns.
Markings unchanged. Introduction of new six colour machines; these presses bear reference numbers which follow on from the numbers of the three colour machines. From the time of their introduction an electronic mark was incorporated on one of each three sheets, and remains so today. The first stamps printed on these machines were the set of French bird stamps, without printing dates (coins-datés), of November 1960. The first dated stamp was the French "Marianne de Cocteau" (7.2.61).
Press number now in thin characters taking the form of "I D 4", "I" = indicatif: "D" = 4th letter of alphabet, therefore 4th press: and also "4" = 4th press. No longer any indication of operators identity. This new system started on 9.1.64 (1f Le Touquet) and only lasted until July 1964.
Press number now indicates type of press.
|e.g.||TD 3 4 =||Taille-Douce||3||colours||press||4|
|TD 6 2 =||"||6||"||"||2|
This system started on 1.7.64 for both types of machine, and continues today.
Appearance of new mark "RGR" - "Presse rotative à grand rendement" = High output rotary press. First seen on 25.7.75 for the 80c red Marianne de Bequet definitive issue of France. This system in current use.
As you will see the present position is that all sheets have the following marks:-
Editors note: 4th period. The dots are positioned in the left margin opposite the 1st stamp of the last row i.e. just above the coin-daté marking. The dots are usually in the colour of the issued stamps but there are exceptions. The 6f Andorre la Vieille was re-issued on 26.7.48 in a different colour (purple brown) with coin-daté 8.7.48. Although this stamp was issued during the 5th period it obviously was printed from the same plates used for the original 6f rose, but it is interesting to note that the dots are albino and not in the colour of the stamp. Another stamp with albino dot markings is the 25f blue Bonell (changed from 25f rose). The 20f violet Bonell has albino markings but the original 20f blue has no markings whatsoever in this position and, similarly, the re-print of the 50f Bonell value with coin-daté 13.4.45 has coloured dots whereas the two earlier printings (6.6.44 and 26.12.44) had no markings at all. Also, some Andorran commemoratives still have coins-datés.
