P2013 Canada Pride -

Hereunder is a pic of my P2013 Canada Pride booklet of 10, with the security feature on reverse.

The other pic, with an accentuated contrast, shows stamps 3 and 4 from the top row. An horizontal mark is running under the sailboat on stamp 3 and under the living flag on stamp 4. It appears to be the same continuous line running on both stamps.

It would be appreciated to ear from anyone having the same flaw on his booklets.

I bought the souvenir sheet and the booklet of 30 for this set. I did not buy the booklet of 10. My stamps from this series do not have the line you show here. Very nice find!

No line on any of mine.

I bought the two booklets of 10. On with security feature the other without. There is no line under Stamp 3 and 4.

No line on mine either.

At first I though reflection in water and foot traffic killed the grass but if no one else has it its an interesting annomoly. Possibly a strand of paper or fiber on a specific color plate (cyan) since you can see the underlying colors. Studystamps may be interested and usually has a ton of material to verify if this happened for any length of time.

Thanks for the feedback. Additional input, negative or positive, wilI be appreciated.

My booklet was received through my standing order with Canada Post.

I hope somebody else will find a similar annomaly.

My guess is it is a repellex variety affecting only the cyan cylinder.

A small drop of water landed on only this cylinder and, due to the movement of the cylinder, 'stretched out' across the cylinder across a couple of stamps. If so, it then tells us the direction of printing (is that important?).

Of course, not having any printing background, I could be completely off base.

Here is an example of a similar variety, but resulting in a 'larger' surface area...



(this picture is illustrated in the front of the Unitade)

Perfect explanation - The whole printing process is based on water and oil(ink) not mixing so a splatter of water or or even a steady drip in the wrong area (likely on a transfer roller) would cause this. Very complex situation where there are numerous smaller rollers, main plate cylinders and blanket cylinders for both water and ink in the same station. Could be a variety that would be on as many as 1000's to as few as a couple depending on how fast it was caught by the pressman. The ones I worked on were quite manual and labour intensive but you had to watch constantly where as newer presses can be set and almost walked away from.
EDIT - Another thing that is often done when rollers build up with lint a quick squirt of solvent will wash everything clean . The idea is to catch the 50-100 items from the finished end and toss them out but all sorts of things squeek through.
Here is an example where the moose stamp has a small phosphorous security feature - but the tehnical explanation points to the station being washed and phophor splashes all over but product not being pulled out.

Thanks for the explanations, they are appreciated.

I always check my stamps for flaws and I find many. However, I don't always understand how and why they happen.

I find your expert comments very informative. This forum is great!

So Major1044, you made me go look at my copies ... no extra lines, just the regular 'no product errors' like 99.99% of the stamps I receive from the Philatelic Service!

Thanks for your feedback Wig. Maybe it's only one of a king.
