Abstract
An offset printing blanket cleaning liquid includes: a solvent having a dipole moment of about 1.7 or more but less than about 4.1 and having a π covalent bond in a molecular skeleton thereof. Moreover, an ink composition includes: an organic material; and a solvent having a dipole moment of about 1.3 to about 3.0 both inclusive and having a π covalent bond in a molecular skeleton thereof.
Claims20
An offset printing blanket cleaning liquid comprising:
- a solvent having a dipole moment of about 1.7 or more but less than about 4.1 and having a π covalent bond in a molecular skeleton thereof.
A method of cleaning an offset printing blanket comprising:
- immersing a blanket in a cleaning liquid including a solvent, the solvent having a dipole moment of about 1.7 or more but less than about 4.1 and having a π covalent bond in a molecular skeleton thereof.
A method of manufacturing a display unit comprising:
- forming a display device on a substrate,
- wherein the forming of the display device includes:
- immersing a blanket in a cleaning liquid including a solvent, the solvent having a dipole moment of about 1.7 or more but less than about 4.1 and having a π covalent bond in a molecular skeleton thereof,
- coating the blanket with an ink composition including an organic material to form a transfer layer,
- pressing a plate with a predetermined pattern against the transfer layer to form a pattern layer on the blanket, and
- transferring the pattern layer to a printing substrate.
