Flats Cancel

I believe this is referred to as a "Flats" Postmark.
Any members advise how they are applied please?

Hi Rod,

I'm surprised no one has commented yet.

This looks like the inkjet applied to most USA first class mail, but covering a larger area.

I have not noticed whether flats are usually done this way, the only flats I have around are from the APS (American Philatelic Society) and they are all hand cancelled by APS.

USPS recently changed vendors for the inkjet cancels, so maybe this is something new from the that vendor.

Yes, spray technology, generally replacing the ugly "tire tracks" style.

They've been around since at least 2009:


And another fairly early one from 2012:


Both images cropped from full covers - yes, I save them whole.

Add: here is the definition of a "flat" from the April 1988 edition of Publication 32, "Glossary of Postal Terms", published by the USPS.

Thank you gentlemen, appreciated.
My query centred around how these were produced.

In my mind, I see machine cancels, covers flowing along a line, STANDING VERTICALLY through a roller mechanism.

These "Flats" cannot do that, I suppose, so there must be another designed machine, where the print head lies above the advancer mechanism.

I was also intrigued how the wavy line, can impinge on the address
then I figured the machine must have 2 spray heads, 1 for the consistant wavy line pattern, and another for adjustable date / address.
I was just curious.

I think they look attractive on covers.

Wow!
Thanks Don......
Talk about "A picture is worth a thousand words"

Rod, To clarify something about canceling machines ... To our viewing, the machines place the cancel the same distance down from the top. This is easily achieved by the mail riding upright along the conveyor belts on its top edge and receiving the cancel the same distance up from the bottom. It's all done upside down!

Ah! had not considered that, but makes sense,
and proven by the three preceding cancels shown.
Thank you.

And it's true going back more than 100 years on all successful high-speed machines - mail passes through the canceling machines upside down so the varying height of the stream of envelopes does not matter.

Yes, it is not obvious, but the 2009 St Louis cancel is on an 6"x9" envelope, and the 2012 South Bend cancel is on an 9"x12" envelope, but the canceling machine only "saw" what it needed to see.

Nice images, John! As a collector of flats cancels I'd never noticed overlap before like the South Bend wave over end of facility id.
To clarify, esp for DStamp, flats or large envelope system is entirely separate from classic letter mail system (now contemporary with automated facers-cancellers and queuing into slots and so on). That recent change in inkjet cancels for the better is over in the letter system. Maker of the inkjet printers might be same now by coincidence.

Two more tidbits about the flats cancels, only U.S. cancels to have days of weeks names in cancel. And a lot of our flats here in the States don't get these cancels at all, arriving completely uncancelled.

Thank you for posting those machine pictures Don

Anyone have Scott Catalogue Number?
NVI value of the Brush Rabbit?

Thanks

From PHILATELIC USPS, 2021, volume 26, quarter 2:

Aha! Thanks Bob.
NVI (20c)
So it is 2021

I rather think it came through the Northgate Mail Centre, Queensland (NMC). I don't know of any Mail Centre in Northcote.
The Scott numbers for the Brush rabbit appear to be #5544 for the s/a pane stamps and #5545 for the s/a coil stamps.

Thanks for the Scott Number Jill.
I find it odd that United States mail to Australia, is routed through Queensland.
Nonetheless, I accept your correction.
