Scott # 37 Colour Question...???

Hi guys

Maybe this is normal, but, how come the stamp is "orange" but some of the shadings (where the arrows are pointing) are red.

Maybe I am seeing too much on this stamp...!

The discoloration is common in this series, and it's not always uniform. I can only speculate that these areas are affected by the amount of ink (too much? too little?), the pressure of the plate on those areas of the paper, or other factors I can't think of off the top of my head. My regret is that I miss these subtleties due to my color-blindness :(

Wert

I am not sure but I think what you are seeing are various levels of oxidation taking place (?)

I have seem some of the 3 cents SQ go to almost a black colour.

Chimo

Bujutsu

That is a possibility Bujutsu, but it is funny that only the areas pointed out by the arrows are turning and in such a unified fashion...You would think if oxidation was affecting the stamp that it would do it randomly...???

Yikes Rileysan...You must have troubles when working with shades of stamps.

Wert I really wish you were close by - I'd buy you a beverage and hang out for a day or two just checking for goodies! It is starnage that the coloration is only on what would be shaded areas . The close ups resemble that other post of the 8c blue that was caused by "dry print" basically where the ink was not at proper consistancy to adhere or release from the plate properly. Oxidation or whatever chemical unbalances in this ink and specifically on this issue is mind boggling.
EDIT- Did you check the perf size? 12.5 might explain a real Indian RED.

nitrolures...Been a while since I have checked perforations, but found my gauge and it is 12 1/4 (twelve and one quarter)...Could be a 12..Not very good at that sort of thing.

Now it looks like a 12 and 1/2...I give up.


P.S. - A beverage sounds tasty...

Wert if you can email me a scan 600x600dpi I will computer perf it. Looks pretty good by the pic so now I'm curious .

Sorry nitrolures...Don't know how in this forum..

nitrolures...Did you receive the email...???

Nitrolures, can you show us/teach us how to ? (Wert if you can email me a scan 600x600dpi I will computer perf it.)

Thought I replied already but must have clicked wrong button.
I got perf 12.25 all around Which I believe would make this a unitrade #41 rose carmine. The carmine part may be the culprit for the deeper red tones.

Nitrolures< I was curious as to the steps you need to go through to computer perf a stamp. I don't know what is involved in this. Does this require a special software?

The link shown is for the perfomaster which does work but has issues. The one I use is a bit more manual but as long as you have photoshop it is easy and accurate.

Here is werts stamp with the gauge overtop. I've scanned a couple dozen at a time and can quickly drag gauge over each - rotate image and do other sides. You need photoshop and I use the image ready part for this procedure. I lined this with points rather than between the divets but either way is same results.

That is true nitro. The issues are missing perforations (pulled perfs). I rebuild the damaged perfs in Paintshop Pro 10 if necessary, and it then it works great.

Thought this might be a good place to put this in for some historical perspective.

My 1991 Scott Specialized Catalogue of Canadian Stamps indicates that the only perf variation on the small queens from the 12 and 11.5 where applicable is the 12.5 for 37d (copper red). In the Scott 2010 Standard they single out the 37d copper red as 12.5. They make no mention of 12.25.

Hansen (The Handbook and Catalogue of Canadian Stamps, 2nd ed., 1973-74) on p30 says "in the First Ottawa a 12&1/2 x 12&1/2 perforation is known on the 3 c". He also says on p36 that "a 12&1/2 x 12&1/2 perforation was used on the Indian Red shade of the 3c. The last mentioned- perforation is very rare and has been found only on copies from the Maritime Provinces of Nova Scotia and New Brunswick. It is also believed to exist on the 1c value although no copies have been recorded to date."
