How do you produce LetterScreen as the fig you attached? I can see IPI in a lot of passports, but not letterscreen. I didn't find any software to make exact effect, and I utilitized matlab to do digital image processing to mimick the LetterScreen/IPI effect after reading Jura's patents but it is quite burdensome.

LetterScreen++ is a Machine Readable function which is available in Corvina. Though you can make it in GSCore which will not be machine readable.

1. Spider Layer
2. Drop Along
3. ArtScreen

Do you know the parameters to make it machine-readable. Or Is it possible to inspect a machine-readable LetterScreen with a conventional machine, like for IPI, you can inspect it with a spectral comparator document checker with the corresponding light source/angle. I don't have Corvina plus. Thank you!
