What Printing Process Was Used For The Point Pelee 2018 Canadian Coil Stamp?

This stamp came on a postcard we received several weeks ago. It wasn't until I examined it under 10x that the real beauty of the detail could be seen.

Even under 10x, a dot screen cannot be detected, but very tiny dots are recognizable. The micro printed "Point Pelee National Park l Parc national de la Pointe-Pelee (ON)" can be seen at the water's edge, upper left. Also, what looks like a sailboat can be seen near the point to its left. The multicolored area is only 20mm x 13mm.

Very impressive printing, but what kind?

bookbndrbob..If your referring about the dots on a picture..The are called halftones..When I was training as a printer, we used this quite a bit...Mater of fact when you look at newspaper pictures, they are 99% halftones.

Below is a great write up about halftones.

Thanks Robert. I understand halftone screens. To be specific, under 10x magnification some minuscule dots/specks can be seen, but there is no evidence of a screen...that I can detect. It makes me wonder if this stamp was printed by the new "deep etch" offset printing method...which I don't fully understand.

Nice link.

Canada Post magazine "Details" states that Point Pelee National Park (Ont.) is celebrating its centennial anniversary in 2018. The stamp is quoted as having been printed by Lowe Martin in five colour lithography (normally now called "offset" by the printing industry.)

Lowe Martin state in a PDF about themselves that "On all of our postal products, we use high-resolution 10-micron stochastic screening. This represents the finest quality being produced for any philatelic community in the world, and is the closest process possible to representing photographic quality."

The use of stochastic screening explains the absence of a traditional screen (as it uses a purely randomly placed dot method that avoids the moire effect when traditional screens are not corrected aligned).

It was not produced by deep-etch offset. It is halftone (this is a correction by me, as I had earlier stated that it was not halftone by mistake).

Thank you very much Glenn! This really explains what I am seeing.

Wert, a careless mistake by me re halftone. Corrected above. Sorry!
