Questions on modern Chinese stamps
When sorting a few modern (1990s/2000s) definitives from
the PR China, I noticed that some of them were overprinted in fluorescent ink with a series of numbers (varying from stamp to stamp) followed by a letter, while other stamps of the same design were not. Judging from the postmarks, it seemed to me that the stamps without the overprint were from earlier print runs. What is the story behind these overprints? What is their purpose, and when were they introduced? My other question refers to the colour of the postmarks: Some "Great Wall" definitives were cancelled in red instead of the usual black. Is there a special significance to the colour of the postmark? Curious, Jan-Martin |

It might take a while until I get hold of a scanner, and I doubt they will show sufficiently clearly - you need long-wave UV light for them to stand out really well. In normal light they are rather pale. For what it's worth, the characters look like they were produced by a dot-matrix printer. Their size is about the one of a typewriter character, or a little less, and there are six or seven figures and a letter. On the "Birds" issue they run sideways, on the "Protecting the common homeland of mankind" issue they run horizontally. Jan-Martin |

Questions on modern Chinese stamps
They are automatic dot matrix cancellers when going through the sorting route. US Australia have similar, some in barcodes, some in date code formats. quite common.

(regarding numbers and letters on Chinese stamps) They are automatic dot matrix cancellers when going through the sorting route. No, I am fairly certain that they are not cancels. These "overprints" (for lack of a better word) are almost white (which is why they are hard to see in daylight or lamp light), fluorescent, and always in approximately the same position for each issue of stamps, always close to the centre of the stamp, and nothing more than a single line of characters such as "0123456A". As for cancellations, the stamps bear the usual black round postmarks with town name and date. Jan-Martin PS: Nevertheless thanks for the interesting images of cancellations, Blair. |

Perhaps they are "control" marks used in the printing process or for accounting purposes. this would be similar to the printing of control numbers on the back of many Spanish stamps. http://www342.pair.com/elerner/stamp...7-dk14748b.jpg http://t2.gstatic.com/images?q=tbn:L...1930_backs.jpg Blair |

The UV numbers that appear on Chinese stamps are identical for all the stamps on the sheet. According to some Chinese websites, these numbers serve as an anti - fraud measure. Richard |

Do you remember the addresses of the websites so that you could let me (us?) know? Thanks a lot! Jan-Martin PS: Does anybody know why sometimes Chinese stamps were cancelled in red? Unfortunately, the ones (Great Wall issue) I have are off-paper, thus I cannot say anything about the letters they were used on. |

Jan-Martin PS: Does anybody know why sometimes Chinese stamps were cancelled in red? Unfortunately, the ones (Great Wall issue) I have are off-paper, thus I cannot say anything about the letters they were used on. Try this one : http://www.hbjy88.com/Article/ShowAr...?ArticleID=158 The article says that the UV numbers were devised as a control measure. The numbers were NOT printed by the stamp printers but handled seperately by another company - Zhong Hong Security Printers in Beijing. Some other points: 1. Initially, only the 15th and 16th stamp of the sheet received the UV overprinting. After it was discovered that dealers were selling the overprinted stamps at higher prices, undistributed stamp sheets were sent to the security printers so that all the stamps on the sheet can be overprinted with the UV numbers. To prevent confusion to auditors, stamp sheets which already had the previous 2 stamps overprinted received overprints which were INVERTED when compared with the aforementioned two stamps. Stamps 15 and 16 on the sheet now has TWO overprints - You can see the picture on the webpage for an example. 2. Additionally, the UV code on some early batches of overprinted stamps covers TWO stamps, so each stamp only received half the code. With these early examples, you will need to get a pair to see the complete code. 2. The UV code consists of a string of numbers followed by an alphabet (eg. 08108230A). Stamps that show an alphabet BEFORE the code (eg. A 08108230A) come from sheets which were shifted during the printing process. The first alphabet was supposed to be printed on the selvedge. Red cancellations These are not very common. Can you post a scan for us to see? I maybe able to read the postmark. I do have a postcard that I posted from Shigatse post office in Tibet which received a red wavy line machine cancellation. Other than that, airmail canchets are in red as well. Richard |
