Abstract
Abstract An ink-jet recording system comprising applying droplets of water-based inks of a yellow ink, a magenta ink, a cyan ink and a black ink onto a recording medium comprising a substrate paper having a surface layer comprising a pigment and a fibrous substance of the substrate paper which are present in a mixed state, and said recording medium having a Stockigt sizing degree ranging from 0 to 15 seconds, to carry out recording, wherein; at least an ink with a dye concentration ranging from 2.5 to 4.5% by weight is used as said black ink; and the recording is carried out in a maximum ink-adhering quantity ranging from 14 nl/mm 2 to 20 nl/mm 2 and in a maximum print-overlap number ranging from 2 to 2.5, is provided.
