Color "error" variations in t206 cards

It is very possible that a yellow negative was shot on a magenta plate for the one on the left. Then it was caught by someone and a new plate was made with the correct negative on the correct plate.

Also, it is possible that the magenta and yellow plates were mislabeled before they went to press or the pressman put the yellow plate on the magenta cylinder and the magenta plate on the yellow cylinder and then caught the mistake and swapped the plates.

I'm glad you posted that graphic. I hadn't seen it before.

It only applies to the modern CMYK process though.
T206s are a combination of halftone and solid passes, and use many more than 4 colors. Where they're halftones most seem to be screened at the same angle.

Here's a closeup of Schlei, showing black, gray, light blue, dark blue, and pink.
Gray and Black are halftone the others aren't.
