How on earth did Sir Arthur Evans manage to read 3,500+ messy Linear B fragments & tablets?

.... without going blind! I just downloaded the first 20 or so actual Linear B fragments and tablets which Sir Arthur Evans unearthed at Knossos from 1900-1903, and what immediately struck me is that most of them are practically illegible, at least online. Of course, the actual fragments and tablets, as housed in museums such as the Herakleion Museum, would surely be easier to read than mere copies online. However, the fragments and tablets must have been a real headache to Sir Arthur Evans and his team of copyists who transformed the contents of the originals into facsimiles, which we actually can read.  So, we owe a huge debt of gratitude to Sir Arthur Evans for transcribing all of those 3,500+ fragments and tablets into the same no. of facsimiles in the Scripta Minoa, published in 1952 by Oxford University Press.

Now, just to make it clear how very difficult... rather I should say, tedious... it is to read any one of the fragments or tablets, I am providing you with two examples here [1] Click to ENLARGE:

Plate XV 04.22 partially legible

You can see for yourself that my own pathetic attempt at merely reading the original tablet was an almost total failure! So you can imagine how extremely tedious this task must have been for Sir Arthur Evans, who had to transcribe all 3,500+ !  And I hasten to add that, without the meticulous and thorough travail of Sir Arthur Evans, Michael Ventris would have had a much more daunting task in his years-long endeavours to decipher Linear B:

In the second example, here [2] Click to ENLARGE:

Plate XV 04.33 legible

I met with complete success, for 3 obvious reasons, [1] it is only a tiny fragment with just 3 characters [2] one of the characters is none other than the super-syllabogram ZE I just recently deciphered... at least to my mind & [3] the second factor directly lead me to being able to actually decipher this fragment. So everything isn’t so hopeless after all.
