Scott 66 - Something To Think About.

Hi guys...I was analysing a couple of blocks I have of Scott 66...It came to me that MAYBE this stamp was done with 2 separate runs on 2 separate occasions and not just one.

Here is my thinking..Below is a block of Scott 66..Notice the line in red at the top that shows even height of each stamp on the plate.




Now below is the same stamp block and notice the line at the top showing uneven printing.




Now here is my theory..
1 - Both blocks are different shade which could indicate separate runs at different time.
2 - Uneven stamps can indicate a DIFFERENT (created separate from the original) plate created to finish the run.

This can only be seen with blocks (or sheets if you are rich)..Not with single stamps....These blocks are definately not take off the same sheets on a single run....DOES THAT MAKE SENSE..?

Robert,

Each position on the plate is "rocked in" (impressed onto the plate) individually so these slight inconsistencies of the stamps in relation to each other on the sheet are common. Sometimes they are slightly at an angle as well. Here is an example on a strip of four of the 1c Decimal Issue.

Wert, wake up sir! You call these two blocks the same block? They may be similar but they can not be the same. Then you state that this can only be seen on blocks, not on single stamps. Of course one can not compare height on a single stamp. AND you missed the bottom right stamp. It is printed higher!
I believe the answer could be very simple. These stamps were printed on a rotary press? If so, the two plates did not necessarily match up. That happened on the Stickney and the Cottrell presses very often.

These stamps were printed using flat steel engraved plates. Boggs states there maybe be evidence of an original plate of 200 subjects (20X10) which was used briefly to print about 500 impressions before being taken out of service. A new plate was produced with two panes of 100 (10X10 each) with a gutter between the panes. The new plate of two panes was rushed into production without imprints which were added later.

The stamp images on the plates were rocked in individually one at a time and offsets between stamps are common.
