Seeking information on Ink bleed on 2p Machin

Hello All,

I am not sufficiently 'into' stamp printing methods to know how this amount of colour has bled onto the margin of the block as illustrated.

I understand how the Doctor Blade flaws are caused but not this extra amount of colour.

Can anyone offer the solution?



Regards.
Ron.
