1923 George Washington Different Perforation

They all look like Scott 185 to me - not really an expert on telling paper type by scan, but I think I see a typical soft porous weave to all three.

That's cool …Thanks

Just out of curiosity I always wondered due to what reasons some rotary pressed stamps somehow has slight traces of ink on the back … I always wanted to ask that question and there you go just did :)

What all of a sudden no one knows the answer to a simple question??

Reallly if someone doesn't know the answer to that then they must somewhere or somehow seek a way to expand their horizon :) … as they say knowledge is everything …

Mate I tell you what the reason I am on here is partially to get a lil more education … but how do you even achieve that when everyone goes silent on you?? there is a reason I asked that question …

Randy Randivoo at least you are different tho but still as useful as everyone else tho … Not sure why you are on here RANDY ???? Isn't this stamp community to make us all more knowledgeable and smarter by listening and learning from one another !?…

So sorry people my extended apologies to whom are irrelevant and has nothing to do with what I am on about ..

And just remember this old saying " BE KIND AND THE WORLD WILL BE KIND BACK AT YA" :)

Until now, you

1. Post images without asking a specific question, yet expect people to reply.
2. Post an implied question and get impatient if not belligerent if there is no answer to what is not a clear question.
3. Get abusive when someone tells you to look at the StampSmarter information that helps you identify stamps that people can only see in scans and, therefore, may not be able to properly assess.

Try to post clear questions, take the advice to look at StampSmarter. If that is not clear to you, explain what is not clear to you and pose your questions in a way people understand it is a question.

and to quote a member:

Now, I do not collect US stamps. I have no knowledge of US stamps.

What I learned from the people you are lashing out at is that some printings were on the web and others in sheets.
After printing the sheets, they were stacked to dry. This caused wet ink to offset onto the back of a sheet stacked on top of another sheet, being indicative of the printing method that required feeding individual sheets into the press.

Did I remember correctly?

Thank you Sir ! I understand …
The point I am trying to make is it fair to say- if a rotary pressed stamp has the right dimensions to it regardless of that tiny specs of ink on the back of it its still a rotary pressed stamp! Am I right or wrong ? … really coming to think about it all it's unlikely but there is still that small probability that anything might of happened during the whole process while the stamps being made, after the stamps are made and during the distribution of any rotary stamps that somehow inherited some tiny specs of in on the back due to human kind error or negligence if you like … I know I might sound silly but it's also what I am trying to say is very possible.. I mean we weren't there and all possibilities should be taken into account and considered… not sure am I out of line here or can anyone see my point !?

Kind Regards

Have you a specific stamp in hand to show us which you believe to have been printed by rotary press from evidence of perforation and or size, but which shows ink setoff on the verso?

We also have to think about what we usually see and know that there are exceptions to the usual all the time.
Some flat plate printed stamps do not have set off because of the printing conditions (low humidity during production, not in the right place in the stack, etc.)
And as you say, there could be things going on in the production environment on a given day which could introduce ink onto the verso of a rotary press printed stamp (perhaps a stray bit of ink on a roller or a problem with the driers...)

If you are looking at a used stamp, you might want to consider transfer of ink from an envelope or postcard onto the verso of a rotary printed stamp applied to said envelope or postcard. A form of post-production stain if you will.

In a word, yes. While setoff is considered diagnostic for a flat plate stamp, ink on the gum-side of a rotary stamp is not impossible ... and, as the previous post noted, such ink may not be setoff but may come from another source. The point to be made is that, for many early stamps, it is important to examine all id clues ... and then come to a conclusion based on the totality of said clues. I know that I sometimes have a bad habit of jumping to a conclusion based on the first clue that I observe. While this is frequently, perhaps even usually, the correct answer, on occasion it will not be. Examining all the clues is especially important for those frustrating stamps that refuse to exhibit the clearly exhibited characteristics depicted in our modern catalogues.
Added: You seem to be considering conflicting clues for a particular stamp, attempting to decide whether it is flat plate or rotary. Perhaps the dimensions indicate rotary but ink on the gum side points to flat plate. There is a question one should ask when considering stamp dimensions in the flat plate vs. rotary scenario. While stamp dimensions can be an important clue, especially for rotary stamps, they can also at times be misleading. I wish the Scott catalogue did a better job of pointing this out. Dimensions for flat plate booklet stamps differ from sheet stamps of the same issue. This is due to the paper grain being different for the two. It took me quite some time to get past this point when I first started collecting. Two "identical" flat plate stamps can have different dimensions when one comes from a pane/sheet and the other comes from a booklet. I even suppose this might, given the right stamp, result in a flat plate stamp being thought to be rotary. I'm not saying that this is what is happening in your instance ... but it is something to consider. Also note that not all booklet stamps have a straight edge, thereby announcing their presence.

Roni,

Do you have a good stamp gauge?

Jack Kelley

Thank you all for your wise words …
The stamp I am referring to is the Scott # 594 I will take few snaps to upload them on here…

And Kelly no mate I don't have a good stamp gauge the only way I trust doing which you will see in the next few pics which I am about to take and upload on here for you guys to see ..

Thank you all and Cheers
Roni
