So, I’m answering this questions:
1. The images with error in word «КолкотоваЯ» (a superfluous letter «Я» on the end) have been printed in a trial variant only on a poster (dense) paper.
The finish variant (corrected) has been printed on other paper (selfadhesive paper)
Therefore there are the color distinctions between the trial and the basic issue variants.
2. The block has been printed without an error in word «КолкотоваЯ». Therefore there are any trial variants in it.
