Scott 274 - Aniline Ink..?

I have used this Scott 274 - N.S.S.C. 256 (Newfoundland Specialized Stamp Catalouge.) as an example.

FIG.1 below are 2 Scott 274 (Cabot in Matthew stamp..."A" stamp is what looks like a normal ink printed stamps).."B" is the stamp am concerned about that may be printed in Aniline ink.

Organic pigment, which is made from carbon, is used for making black ink.
Inorganic pigments, which are made by mixing various chemicals together, are used for colored inks.



Here is the back of these 2 stamps.."B" stamp has all the characteristics of an Aniline printed stamp.
..The bleed is usually caused by thinned out Aniline stamps.
Aniline ink is dissolved in alcohol or other volatile solvents.
A lot of normal inks are oil based.



Below picture shows "A" as being a normal printer ink printing
on the word postage and "B" has the characteristic of blurry ink results..(Aniline)



Both A and B stamps have slightly different colours as shown below.



Below is a drawing showing the difference between normal ink and aniline ink...I am showing this drawing because of my 5 years experience in Lithography in my early years..
Normal ink has a certain tackiness to it because the skin texture is present, while solvent based inks such as Aniline ink is the same as putting paint thinner to have paint spread more easily.
Also Solvent based inks will penetrate paper more than normal, and thats way Aniline ink bleeds through paper easily.



This issue had 5 million stamps printed, but only 1000 were printed with Aniline ink..Going under what collectors say that approx. 10% of stamps still exist..This means probably best estimate, only 100 survived over the years.

Bottom line..stamp "B", Aniline or not..

Thanks, that's a very helpful explanation.

Hey Wert

There is an example of an NFLD 270 Aniline ink in previous post

I dont think there is any known used copies of the aniline ink of this stamp

If "Aniline ink is dissolved in alcohol or other volatile solvents" - that means that you can't use watermark fluid on it? The fluid, like lighter liquid, is based on low boiling-point organic solvent.

Check this existing item as well.

At the bottom, I posted side by side images of mint versions--as with Wert's example above. The only way to understand is to see them in person or side by side.

always be on the lookout for this--I recently found one in a normal pile

Tommy - where are the scans ?

There is a previous thread posted by Wert.

Attempting to include the weblink to that :

If not, search on "Newfoundland blotchy"

By the way, I believe this is Unitrade #270

Tommy, you are correct..Never type and talk to the wife at the same time..haha

I hope this provides some clarification

NFLD 270 normal on left with NFLD 270iv on Right

Hi Wert, Your used example on the right looks like a normal stamp with some feathering. The "aniline-type" looks very different. See image. Tony
