Security personnel accompanying the chief minister grappled with the man as he shouted slogans and then handed him over to the local police.
Most of the ink fell on the security personnel but some landed on Khattar's face and hair.
Khattar pulled out a handkerchief from his pocket and was seen wiping the ink off.
The incident took place ahead of a roadshow by the state government in Hisar this evening.
Before being taken into custody, the youth raised slogans and claimed he was an activist of the Indian National Lok Dal.
He said the man was being questioned.
Kumar said it had not yet been verified if he was an activist of any political outfit.
