E90-1 "shaded" back variations?

[edhans]

I looked at each of my 99 E90-1s (93 diff, 6 dupes). Found only two with the shading, both Fromme. The shading is not identical on the cards. The other Cincinnati players (Mitchell, Bescher, and 2 Siegle's) do not have the shading. I'm inclined to agree with the majority that it's not a variation, just a dirty or worn plate. As Scott points out though, if we could establish definitive patterns it might help to solve the elusive mystery of e90-1s series.

confirmed here also...

Fromme is one!

not a dirty plate, but a DIFFERENT plate....

a dirty plate would leave smudges on the inside AND outside of the lines...

no smudges are found on the shaded variation...in fact they are quite "clean"

thanks Ted for this quote that puts things in perspective..

scott - there are a many ways this could happen on press through poor quality control..... or simply during the initial setup (make-ready) for the run.

for instance.... all one has to do is run too much black ink (or not enough water) and you will achieve that plugging in (you call it shading). If a pressman saw that the black was running heavy, he would have adjusted and kept running. What you see is the bad printing that was fixed.

This is not a variation.

no matter if is on just one card, some cards, or all cards - this is a print defect..... as the issue can happen on the entire sheet or on a specific part of the sheet.


As far as printing plates....
and your mentioning "DIFFERENT" plate....
I mentioned this before -

Printing plates only have so many impressions in them.
I don't know the number of sheets that could be run off by a plate in 1910ish.... but I would bet it wasn't more than 10,000 sheets - probably less.

To compensate for the short life span of printing plates - multiples of the same printing plate are produced.

So.... for just about any mainstream card we collect - - there were MANY plates created for the same card. As plates outlived their usefulness, a pressman would take off the bad plates and put on the new (but same) plates.

so i will use the word VERSION instead

SHADED VERSION....


only certain cards have the shaded Version....


better?

Scott....

I think the thread is awesome.

And I love the observation.


you really could call this anything you want.

I was just trying to be a constructive participant of the thread.

i appreciate it! you are the expert on printing and this discussion is great!



how about this....some cards have a Regular version and a shaded version....is that not true?

[ScottFandango]

How come then, say the Fromme, has regular versions and shaded versions, BUT NOTHING IN BETWEEN...

wouldnt it be a slow progression from clean to dirty? havent found that... I havent seen any Frommes that have "just a bit if shading"..has anyone?>
