All nails were done with the tutorial I linked to above.

Nail Prep:
2 coats OPI Skull & Glossbones
1 coat Poshe

Note:
If you're having problems with the newspaper print not being dark enough, try a lighter base coat. It can make a HUGE difference. I tried this with Essie Nice is Nice and the print came out too pale. Just know that pale newsprint may not be due to your technique at all, it may be your base coat.
What I Used:
70% Rubbing Alcohol
Vodka
Hand Sanitizer
Almond Extract

My Results:

Index Finger - 70% Rubbing Alcohol
Middle Finger - Vodka
Ring Finger - Hand Sanitizer
Pinkie - Almond Extract
70% Rubbing Alcohol

Not bad, absolutely a great alternative. Unfortunately, though, I had to redo this nail several times to get it to look this way. I don't know if it's my nail shape or the rubbing alcohol, but it kept missing parts of the text. The intensity of the text is great, though.
Vodka

This transfers the text SO quickly. If you're looking to do this quickly, vodka is the best out of all of them. Intensity is very similar to the rubbing alcohol, but I don't feel I can do a complete comparison because some text didn't transfer right with the rubbing alcohol, which makes it look more faint.
Hand Sanitizer

Nope. Didn't work. Well, sorta worked, but no where NEAR as well as the others. I'd definitely say don't even bother.
Almond Extract

Umm, yes please!! I cannot believe how well this came out. I think it's my favorite. The text is very sharp, the color is very dark, and the extract smelled delicious!! The texture of the extract makes it very easy to keep it on one spot on the nail. I think that helps attribute to how well it works.
Which do I think is the best?
Honestly, I vote the Almond Extract. And the fact that it smelled DELICIOUS makes it that much more awesome.
Overall Opinion:
If you're looking for something besides vodka, go with an extract. The Almond Extract I used is clear (I say this because some extracts are not clear), and it lists alcohol as the second ingredient next to water. It uses 36% alcohol. Even if you have vodka, I still suggest trying an extract. The results are amazing. I'm sure other extracts, such as vanilla, orange, mint, etc would work fine, but the vanilla extract I have isn't clear, so I thought that might cause problems. The almond extract was clear.
I would also recommend rubbing alcohol, though it wasn't my favorite. It did a fine job transferring, so it will certainly work.
As for the hand sanitizer, don't waste your time.
Note:
I know that the close up photos still look fuzzy. This is because I'm shooting in macro. In real life, you canNOT tell there is fuzziness on the index, middle, or pinkie. And when I say the pinkie is the sharpest, even if it doesn't look it in the photos, it is. It's amazing.
