Quinacridone nanocrystals with controlled size and morphology were readily fabricated by using a pump as an injection apparatus of the reprecipitation method for mass-production and injecting concentrated N-methyl-2-pyrrolidinone solution. Encapsulation of quinacridone nanocrystals using polymer was achieved and quite improved dispersibility was confirmed for the encapsulated nanocrystals.
