Ink-jet printing paper and ink-jet printing method using the same

摘要

The printing paper can be formed by applying a slight amount of paint including a white pigment having a given BET specific surface area onto at least one side surface of base paper having a given apparent density. Also, according to the printing paper, in a time T=L/S to be determined by the shortest inter-nozzle distance L of different colors of a multi-color ink-jet printer and a printing paper/head relative moving speed S, the ink absorbing capacity V of the printing paper according to a blister method satisfies the following equation: V>/=2ax2/(0.0254)2 (where a represents an amount of ink drop to be jetted out from a nozzle, and x represents definition). The present ink-jet printing method uses the above-mentioned printing paper.
