I've translated 'imprint' into 'promsigno' in Esperanto on Google.
Anyone can analyze the word 'promsigno' (what i mean is that splitting that word, that word is combined by what other words, ect..)?
Thanks for answering my question.

'Imprint' can be translated 'premsigno' or 'surpresi' or 'ŝpuro' - if you look variants, Google gives them all.
'prem-sign-o' - a mark made by pressing something onto a softer substance so that its outline is reproduced

But all they aren't good for this meaning:
(of a young animal) come to recognize (another animal, person, or thing) as a parent or other object of habitual trust.
