<P>PROBLEM TO BE SOLVED: To provide a multi-concentration inkjet ink set both having a reduced ink consumption and a more rapid drying time, and to provide a process for inkjet printing which produces an image of high image quality showing reduced coalescence, good color reproducibility and improved light resistance. <P>SOLUTION: The multi-concentration inkjet ink set are a multi-concentration inkjet ink set which comprises two kinds of black ink compositions and at least three kinds of color inks, wherein the first black ink composition has a lightness L<SP>*</SP>in a range of 35-65 calculated from the spectral transmittance of the diluted product of the first black ink composition diluted by 1,000 times, and the second black ink composition has a lightness L<SP>*</SP>in a range of 70-100 calculated from the spectral transmittance of the diluted product of the second black ink composition diluted by 1,000 times. Also, there is disclosed a process for inkjet printing. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
