A recording method includes: recording a first image on a recording medium; reading the first image to determine whether the first image is correctly recorded; and when the first image is determined as not being correctly recorded, recording a second image over the first image. The water-based recording ink includes a water-soluble organic solvent which is at least one selected from the group consisting of a glycol ether and a diol compound having six to eight carbon atoms and two hydroxyl groups, at least one of the two hydroxyl groups not being bonded to a terminal of a carbon chain of the diol compound. A content of substances having a vapor pressure of 0.03 hPa or less at 20° C. in the water-based recording ink is 10 mass % or less and a surface tension of the water-based recording ink is 30 mN/m or less.

A pigment dispersion for an inkjet ink contains pigment particles, styrene-acrylic resin, and water. The styrene-acrylic resin includes a first repeating unit having a group represented by formula (1) and a second repeating unit not having a repeating unit represented by formula (1).

##STR00001##

The first repeating unit has a percentage content to the total mass of the first repeating unit and the second repeating unit of at least 1% by mass and no greater than 10% by mass. In formula (1), R.sup.1 represents a hydrogen atom or a methyl group, R.sup.2 represents a hydrogen atom or an alkyl group with a carbon number of at least 1 and no greater than 7, and m.sub.1 represents an integer of at least 4 and no greater than 9.

An inkjet ink has a volume reduction rate ΔV calculated using formula (1) “ΔV=100×(V.sub.0−V.sub.22)/V.sub.0” of at least 25% and no greater than 45%. In the formula (1), V.sub.0 represents a first volume of a liquid droplet of the inkjet ink at landing, on a non-absorbent recording medium, of the inkjet ink dropped onto the non-absorbent recording medium. V.sub.22 represents a second volume of the liquid droplet when 22 seconds elapse from the landing of the liquid droplet on the non-absorbent recording medium.

The present disclosure provides an ink fluid set containing an aqueous pretreatment composition and an aqueous inkjet ink. This ink fluid set is particularly suitable for printing on offset coated media.

The invention provides dispersed inorganic mixed metal oxide pigment compositions in a hydrocarbon media utilizing a dispersant having polyisobutylene succinic anhydride structure reacted with a non-polymeric amino ether/alcohol to disperse a mixed metal oxide pigment in the media. The metal oxide pigment is of the type used to color ceramic or glass articles. A milling process using beads is also described to reduce the mixed metal oxide particle size to the desired range. A method of using the mixed metal oxide dispersion to digitally print an image on a ceramic or glass article using the dispersion jetted through a nozzle and subsequently firing the colored article is also described.
