Here's a stamp from Columbia with extra odd looking marks in the left and right margins. The marks on the right look smudgy but the marks on the left look quite sharp.
No. This is the only one I have. But the guidelines at the lower right and lower left are normal. It is the marks higher in the margins that I am trying to decipher.
The best explanation I can come up with is: When the paper was lifted off the plate, it accidentally fell back on the plate and picked up some extra ink. This is called a Kiss Print.
KGB is right just sloppy printing ,the guide lines were suppose to be filed down by the plateman before put on the press . Inspector not doing quality control.
