Estimating the term…
A mailing ink, an ink tank for mailing, an ink jet recording method for mailing and an ink jet recording apparatus for mailing that can reconcile preferable tint and visibility as indicia with readability by a 2-D bar code reader. The ink is a mailing ink used in ink jet recording. In the mailing ink, the ink tank, the ink jet recording method, and the ink jet recording apparatus, the ink provides an ‘a*’ of from −10 to 15 and a ‘b*’ of from −50 to −15 according to the CIE L*a*b* color system in a printed portion obtained by applying the ink to a recording medium so as to give an application amount of ink of 4.5 mg per square inch, and provides an integrated value of reflection spectrum of 90 or lower in a wavelength region of from 380 nm to 730 nm in the printed portion.
A mailing ink for use in ink jet recording, which provides an ‘a*’ of from −10 to 15 and a ‘b*’ of from −50 to −15 according to the CIE L*a*b* color system in a printed portion obtained by applying the ink to a recording medium so as to give an application amount of ink of 4.5 mg per square inch, and provides an integrated value of reflection spectrum of 90 or lower in a wavelength region of from 380 nm to 730 nm in the printed portion.
