American Bank Note Trinity Process?

In the early 20th century, American Bank Note created a tightly registered printing method of commercial lithography that they called the "Trinity Process." Initially, this was three color (hence Trinity), but I think it expanded to four or more. I don't know whether this was used on stamps that ABNC printed.

Here's an ad that ABNC used to promote the Trinity Process:

Although the company was happy to promote this service to customers, they were protective about how it actually worked. I'd like to learn more about it if any members have more information.

Hi Greg,
I see the ad includes the address of 86 Trinity Place NYC...isn't 86 Trinity Place currently The American Stock Exchange Building (built in 1921)? What was there before the American Stock Exchange Building?

Edit:

The Curb Market purchased a 26,000 square-foot, L-shaped plot btwn Greenwich Street and Trinity Place in Dec 1919 for $1.6 mm.

Site had been former location of a bldg occupied by the ABNCo.

ABNCo relocated to 78-86 Trinity Place in 1882. And left the site c 1908.

So maybe "Trinity process" is from the address and not 3 colors?

I have faith that the name arose because it took an act of God to get the printing colors properly registered.

Well played!

There's a poem written by Elie Loizeaux, one of ABNC's longest serving engravers (53 years). He wrote this some time after the company moved to their new location, which evidently he wasn't fond of:

Oh Trinity Bells! Sweet Trinity Bells!
How fresh within the mem'ry dwells
Of happy work and good old times
When last we heard your soothing chimes!

Those joyous hours are passed away:
And many a heart that then was gay
Within this tomb now darkly dwells,
And hears no more old Trinity's bells.

And so 'tis now since we are gone —
Though tuneful peals you still ring on —
"Trinity Process" now compels:
We punch the clock and hear the bells.

Hi Greg,
I bought this up today at lunch and found out that you and Frank have discussing this topic. Also found a thread from 2019 in a paper money forum where you mentioned this topic.
You might have already seen this but posting them for completeness

I forgot you were one of the legendary lunchers, Don. :-) Thanks for the post. ABNC loved those tomatoes to show the depth of color. I'm still trying to find out whether the Trinity Process was used on stamps, currency or other security printing.
