This is the back of the stamp, a Newfoundland 110. What do you call a stamp that has the image showing from the reverse? I have not see one before. The black checkmark is from the scanner.  |

Good question. Since it is a mirror image, perhaps the sheet from which this stamp is taken somehow got laid on top of wet ink from the next sheet. I've seen such on stamps that got wet in albums and picked up the imprint of the black album image, but yours is the color of the stamp. Perhaps it was over inked. Is the image under gum (even partial gum) or on top of it? Does it match exactly the front of the stamp? Don't know the proper parlance for such.

The image is, of course, the stamp image from the front showing through on the back (mirror reversed). Is the gum removed, so one is just looking at the paper? Scott has a note for Newfoundland Scott 110 that the "paper is colored through".  I checked my Newfoundland 110, and it has yellow gum on the reverse, so the back (reverse) image is not as obvious as your copy, I've noticed stamps on pelure paper also often have the image showing through. |

The stamp appears to have full gum. So, apparently this is somewhat normal for this issue. Something new learned!

Geezer, I do not think it is particularly normal. My copy looks pretty normal from the reverse with the design just barely visible. It looks to clean for a double transfer and so I think it is that the ink has bled through. I've noticed this since I was little kid from stamps all over the world. I think it probably has to do with the moisture content of the paper. I seem to be missing something obvious. lost in my memory banks at the moment so perhaps it will come to the surface and I can offer more. You know if you rub most old stamps with oil they will do basically the same thing. I have an example of a Greek stamp that shows the same type anomaly at top of the page below. However this stamp was printed with aniline ink and this occurance is common with this issue.  |

This is the back of the stamp, a Newfoundland 110. What do you call a stamp that has the image showing from the reverse? My first thought was just what Mitchell had suggested, aniline ink. A quick Google on "Newfoundland aniline ink" turns up this article from a 1951 issue of BNA Topics - it states that the 8c value was printed on aniline ink. 1951 BNA Topics journal articleRyan |

Thanks for the link. Even though the article discussed the 4c, is it possible the 8c blue was produced with aniline ink? Scott makes a note in the catalogue that the "paper is colored through", which is quite characteristic of aniline ink.

Ryan, jkjblue, or anyone, one definition of aniline ink is:
"An inexpensive volatile printing ink consisting of a dyestuff dissolved in a methylated spirit and bound with a resin. It is considered to be a very fast drying ink. Aniline inks are considerably inferior in permanence to many other types of ink, and are also subject to smudging by water. Although all colors are available, they are lacking in COLOR FASTNESS . (144 ) "
So, what would cause it to be used on stamps?

Ryan, thanks for clearing that up. Scott does not sate that aniline ink was used on that stamp. It does not (most times) exhibit that affect, however. Like I said mine looks normal and many other issues that use it are less likely to show through as well. I think it has something to do with the moisture content of the paper. Could also be that they were using two types of ink, or the ink wasn't mixed correctly or ?

Geezer did not see your last post. Sounds like it was pretty inconsistant stuff to print with and I guess that explains it well enough.

Ryan, that bnatopics journal is great, I had lost track of it, but now have it bookmarked (again). Very handy!

Scott makes a note in the catalogue that the "paper is colored through", which is quite characteristic of aniline ink. The last sentence in the article does say the 8c was printed with aniline ink - it was discovered before the 4c. Ryan |

You know if you rub most old stamps with oil they will do basically the same thing. For a while, "modern" Canadian engraved stamps were being sold on eBay as being printed with aniline ink. I got hoodwinked and bought one of them! Not too tragic, though - I think I paid $1.95 for it, something like that. It looks like it has been soaked in some sort of light oil.   Ryan |

Ryan, that bnatopics journal is great, I had lost track of it, but now have it bookmarked (again). Very handy! There is a tremendous amount of online content for Canadian philatelic journals. Here are some links that I use the most often: BNA Topics, 1944-2008BNA Topics as above but limited to Newfoundland articlesThe Canadian Philatelist, 1950-2006Centennial Definitives Study Group, 1981-2004The Corgi Times (Elizabeth II Study Group), 1992-2006Newfoundland Study Group, 1985-2008 over 20 other study groups including Large Queens, Small Queens, KGVI, RPOs, precancels, airmails, fancy cancels, etc. etc. Ryan |
