PURPOSE: To obtain a printing substrate having the printing quality comparable to that of coated paper and high tear strength by forming an ink fixing layer capable of manifesting a specific surface roughness on one side of a nonwoven fabric composed of polyolefinic three-dimensional netlike fiber.

CONSTITUTION: This printing substrate having high printing quality is obtained by subjecting a polyolefin (preferably polyethylene) three-dimensional netlike fiber nonwoven fabric to calendering, then coating at least one side thereof with preferably a carboxylated styrene-butadiene-based latex, subsequently drying the coated latex with hot air, then carrying out the water-resistant treatment and forming an ink fixing layer having 0.4-0.7 surface roughness (an SMD value measured with a KES(R) surface tester). This substrate has better ink receiving properties and a higher grade than those of a conventional nonwoven fabric.
