Chinese Overprint Ink?

Seems different could just be me but stands out as different then
Any I have to reference
Probably nothing

Different as what? You are showing two different stamps here

Peter

I'm horrible at this apparently lol
Can I ask someone to post the same stamp
I'm using a old book and the internet to look things up
So please bare with me
I appreciate the help
It's probably funny ink or damage or bad pressing or something you already know about
that means nothing I'm sure
But I'm new to this and looking for interesting things that stand out and seeing
I don't have The best resources (yes I'm gonna get a updated book)
But for now I google and use what I got

For comparison

Thanks
Appreciate it

Now is there a term or something to call the extra ink or what ever happened
To the stamp I I posted
I know it's probably nothing
Runny ink or doubling,worn out or bad pressing or simply extra ink lol

Looking at the perforations they might be different printings? Also could simply be over inking.

In the pic shown by stallzer.it's printed on native paper,while the stamp shown by just_fella is on white paper.
(Japanese occupation North China,New Peking printing 1943,Scott 8N72)

There's nothing wrong with the stamp.

Refer to the 1939 - 43 series for the base stamp. There are numerous surcharges and overprints which you will need to work through.

As noted earlier you have elected to start with one of the more challenging collecting areas (equipped with few resources).

is it just simply called over inking on the stamp?

Or under inking

I just read through 2 pages and have no clue as to what the OP is asking about.

Overinking is normally when you have an abnormally large amount of ink. It would look like very blurred letters, sometimes with sections completely blocked out so you can't tell what the letter was meant to represent.

Underinking would be the opposite. This is when there is too little ink, hence the letters may be incomplete and missing dotted i's or crosses to the t's, etc.

Best way to ask questions on this forum is to show TWO stamps ... one with the problem, and one which is "normal". All I am seeing in this thread is two different stamps, and a circle in an area of one of them. I have no idea what the issue is with the circled area.

And, like others, best recommendation is to check out your library or purchase a more recent catalog to check for these items. China overprints are numerous, and very difficult to find, even after searching through tens of pages. Good luck.

Ok
All I'm asking about is the ink difference
It's probably a simple thing lol

So under inked?

As perf12 has already told you, your stamp is part of a special series prepared for use in a part of China under Japanese occupation. (You do know about that, right?) These stamps were of poor quality and often display slight alterations in the designs. That's probably why your stamp has some sloppiness in the inscription at the bottom, which says (I believe) "Republic of China." Now make an effort to find stamp #8N72 in your catalogue. Doesn't matter that it's an old one. Just look for it.
