[Ohiodig] "Jellification" of Text

[Klose, Annamarie C.]

Noah,

It’s probably related to the OCR conversion process. It’s something that I’m used to seeing occur often. On a related or unrelated note, here is an older post from a digitization expert (https://page2pixel.org/2013/08/when-copiers-arent-copying-as-they-should/) that mentions copy/scan stations interpreting numbers incorrectly and changing them in derivatives. The blogger is a former colleague who is respected in the digitization field.

Subject: [Ohiodig] "Jellification" of Text

Dear All, What causes this "jellification" of this document? Compare with a normal version of the exact same document as found on the Internet Archive. It almost looks like the file was changed from a raster to a vector image. ‍ ‍ ‍

Dear All,

What causes this "jellification" of this document<https://urldefense.com/v3/__http:/www.ideals.illinois.edu/handle/2142/45719__;!!KGKeukY!xMCW2RgWGh7Lu9FB7-G2APVb78qYt_rS7xrXDBgfo0WD-PRoK-xP1Kxd3LaphG684mpI24jdKkDUxVBe_BeNElbLGQJoom56$>? Compare with a normal version<https://urldefense.com/v3/__http:/archive.org/details/evaluationofscho08flex__;!!KGKeukY!xMCW2RgWGh7Lu9FB7-G2APVb78qYt_rS7xrXDBgfo0WD-PRoK-xP1Kxd3LaphG684mpI24jdKkDUxVBe_BeNElbLGbWHI2i-$> of the exact same document as found on the Internet Archive. It almost looks like the file was changed from a raster to a vector image.

I've run into it a few times – although never with anything I've scanned – and the best explanation I can think of is that it has something to do with text recognition software. For text only documents it's not a major issue, but unfortunately I've seen it turn some diagrams into an unreadable mess.

Sincerely,
