How paper-tag survive in the dry-cleaning process?

This prevent the clothes from being ruined by **ink** on the paper tag.


To put the garments attached with this paper through the whole process of dry-cleaning,


I have the questions listed below 


1. paper type?
2. ink type?
3. Is paper need to be coated?
4. if need >> what is this coating technique called?
5. printing technique (refer to <http://en.wikipedia.org/wiki/Printing>)


Note that, the **dry-cleaning solvent** is not just water.

Does that sound scientific?


I don't know the more appropriate place to ask this kind of question. If there is, just let me know.


Thanks,
