US Scott Specialised Catalog Question

In US Scott 2025 Specialised Sc13 has a listing for Double Transfer for position 100R1 - which here I posted here: https://goscf.com/t/72775&whichpage=245 I had asked 2 questions. Maybe I posted in wrong thread - ? Anyhow I got one answered but still looking at double transfer printing.

I posted a cert which lists desc as 100R1 , but am told its not that position - so be it. Still waiting to hear back from PF. But I also asked in thread about 5 times is all 100R1's are double transfer printings and got no answer. So trying here - are all positions from that location double transfer printings or not? Guessing not, seeing as its not listed on cert- but unsure. Auction house would not answer question and referred me to PF. Tks - new to these and US plating.

EDIT: fixed link - I hope!

I don't have a catalog in front of me, but it I lists a position as a double transfer, every stamp of that position will be a double transfer. Double transfers happen when a transfer roll gets out of alignment and creates a second (usually much lighter) imprint when creating a plate, so the double transfer exists on the plate, and every stamp from that position on that plate will be a double transfer.

Many thanks for clearing that one up! Appreciated.....

might I throw another question in here..... I also have the attached which was mentioned in listing as "Ex. Neinken & Wagshal....".




Also as a plate 11 triple transfer as mentioned in the Neinken book, pages 474-476. Some pages:





Is the above enough to confirm triple transfer? I THINK I see some of the details mentioned on the article, just checking. Also, can anyone list any available .pdf's and source with more info? I have the neinken .pdf but wondering if more & where? Also, to switch gears, on the Sc 13, ten cent washing, Type I, position 100R1. It was mentioned on another site a book by Ashbrook , but I cannot find the .pdf.


I hope all this is not too off topic - if so , please move. Thank you!

A little clarity is needed here. Stamps are engraved on steel dies in reverse image. When the die is approved (following the creation of large die proofs and trial color proofs), the die is hardened and used to make transfer rolls (containing several positive images to speed up the plate production process). The transfer rolls are hardened. The production plate (soft steel) is laid out with grid lines and position dots to guide the placement of the transfer rolls. Once all the negative images are laid out on the plate, another round of proofs are made, generally on india paper, to make sure all the positions are properly engraved, prior to hardening the plate. If there is some minor weakness in 1 or more images, there are two options to repair the plate. 1. Some weak lines can be recut to deepen them so they accept more ink or (2) the image is hammered out from the back and a new transfer is made. If some of the image is not properly hammered out, a double (or even triple) transfer can occur. Since this occurs in the individual plate position, the double transfer will repeat consistently until (a) the plate is replaced or (b) the extraneous lines are worn off. If, however, the "double transfer" does not repeat, it can be due to either some foreign material that was on the plate for a short time or from a kiss print if the stamp paper shifts a bit during the printing process. Other things can occur as well. The "dot in S" on US #1, for example, was caused by foreign material on the tranfer roll used to lay out column 9 on the copper printing plate in 1847. Note- the transfer roll can get out of position while it is rocked back and forth to make the impression on the plate but this is not usually the source of the double transfer, but rather just a misaligned transfer. Most double transfers are due to failed attempts to exactly correct the plate before making a second transfer

Stamps4Life - I see you have acquired this stamp from the Cherrystone Bob Boyd Sale. Congratulations, it is a great piece. It is clear that this stamp matches the Neinken illustration. Whether or not it was produced as a result of an actual triple transfer (i.e., three separate entries from the transfer roll) has been a matter of some conjecture over the years, but at present it is generally referred to by that term. Plate 11 is notoriously undocumented. If you have the Boyd Sale catalog there is an article embedded in the middle describing efforts to reconstruct this plate, led by Bob. But as of now the Neinken book is probably the best treatment you will find. A search of the PF datadase on Sc #22 keyword "triple transfer" yields only one hit with a not-very-useful image.
