Ghost Overprints and Stone Lithography

does that mean both techniques must have been used in some manner? otherwise how do you get a reverse image of the same stone?

I don't know that T206s are stone lithographs, but that's really just a mnor technicality because its merely a matter of what the printing plate was made out of (limestone versus metal). Doesn't change the printing process or theories. As noted transfer lithography, which involves an intermediary step, allowed an image to be backward or foreword. I suspect they originally introduced it so the original art could be made normal instead of backwards. The artists didn't have to draw in reverse left to right.

The exact cause of specific ghosts are a mystery to me, and different ghosts may be the result of different situations. But, between wet transfers and transfer printing, it's definitely possible to get the reversed images.

Have to admit the first time I saw a ghost my first reaction was it was fake because the image was reversed, but I have no reason to disbelieve it now.

The other reason for transfer lithography is that the paper is usually very slightly abrasive. Printing to the intermediate rubber roller reduces plate wear.
It's also usually a drier process than direct lithography.

Direct lithography is still used for art prints. Plate wear isn't usually a big deal if you're only doing a few hundred impressions (Or less) And a good manual printer can control the inking better especially if there's an area that's troublesome. Like the thin space between the frame lines of the Piedmont backs which are sometimes filled in because of the plate drying out a bit too much

I don't know much about lithography either but that seems to be a big process to use both stone and metal for one sheet of cards .

It's not usually both in production. More modern stuff except art is always metal plates.

But metal plates were fairly new in 1909-10, And a lot was still done using stones as the plates. Figuring out which was used is very hard.

At the time a lot of the plates were laid out using transfers which were probably printed from stones. A lot of the stones that are still around have multiple items on them, like billheads from 3-4 different companies, or parts of labels from unrelated brands.

from my collection. Circa 1910's stone featuring tintags and believe it or not - images of Colgan's Chips containers. When they no longer used them - they sometimes would end up in fills and driveways! These later stones @ around 10" x 12" were easier to minipulate than the earlier ones - stones that were much "chunkier" and heavier. Utilizing multiple color passes would require multiple pressings - no easy task especially in lining up the correct scheme.

Just curious if you bought that stone at one of the Cleveland Nationals (2007 or 2009)?

Looks like the same stone I had the chance to buy and passed on. Wish I hadn't.

I don't think so... if the off-set method is used, then the stone is image looks just like the actual card (not reversed). It's transferred to a rubber roller, which at that point IS reversed, and then transferred again to the paper reversing it a second time to essentially "un-reverse" it.

I think the ghost overprint has to be an instance where the paper was pressed on the original stone, thereby reversing the image.

In either type of offset press (Stone or plate) the paper shouldn't come in contact with the plate. Those very clear offsets are usually from a misfeed causing the offset blanket to print to the impression roller which is a nice smooth steel. If it's a minor misfeed and the press isn't stopped then the next sheet gets an impression from both the blanket and the impression cylinder.

The paper does sometimes contact the plate. But it's a bigger problem, and the result looks awful. And nearly always ends up in the round file. Basically the paper or what's left of that sheet gets inked, and prints a nearly solid layer of that color to the next sheet. If there is one. The sort of jam usually involves the paper tearing or peeling so some winds around the blanket.

I still haven't quite figured out if they were done with stones or plates. I'm almost positive the backs were done with stones. But I'm less certain of the fronts.
