Abstract: A white ink for inkjet printing contains titanium oxide particles and an aqueous medium. The titanium oxide particles include anatase-type titanium oxide particles and rutile-type titanium oxide particles. The anatase-type titanium oxide particles have a percentage content of at least 17.50% by mass and no greater than 37.50% by mass in the titanium oxide particles. The rutile-type titanium oxide particles have a percentage content of at least 72.50% by mass and no greater than 82.50% by mass in the titanium oxide particles. Both the anatase-type titanium oxide particles and the rutile-type titanium oxide particles have a number average primary particle diameter of at least 140 nm and no greater than 340 nm.

Abstract: A white ink for inkjet printing contains titanium oxide particles and an aqueous medium. In particle size distribution measurement for the titanium oxide particles, the titanium oxide particles exhibit at least a first peak present in a particle diameter range between 40 nm and 55 nm and a second peak present in a particle diameter range between 165 nm and 340 nm. Where of the titanium oxide particles, titanium oxide particles with a particle diameter of at least 40 nm and no greater than 155 nm are taken as first titanium oxide particles and titanium oxide with a particle diameter of at least 165 nm and no greater than 340 nm are taken as second titanium oxide particles, ratios of major axis length to minor axis length of the first titanium oxide particles and the second titanium oxide particles each are at least 2 and no greater than 15.

Abstract: An ink set includes an inkjet ink and a cleaning solution. The inkjet ink contains a first aqueous medium, a carbon black, a dispersing resin, a first zwitterionic surfactant having an amidoalkylbetaine structure, and a first sugar alcohol. The carbon black has an oil absorption number of at least 130 mL/100 g and no greater than 165 mL/100 g. A ratio of a content of the dispersing resin to a content of the carbon black is at least 12.0% by mass and no greater than 19.0% by mass. The cleaning solution contains a second aqueous medium, a second zwitterionic surfactant having an amidoalkylbetaine structure, and a second sugar alcohol.

Abstract: A fabric inspection device includes a sheet conveying portion, an image reading portion, a timing control portion, a storage portion, a comparing control portion, and a display portion. The image reading portion reads a plurality of images of the same pattern recorded repeatedly with a predetermined pitch on a recording sheet conveyed by the sheet conveying portion. The timing control portion regulates the timing of image reading by the image reading portion. The storage portion stores the plurality of images read by the image reading portion. The comparing control portion takes, out of the plurality of images stored in the storage portion, part of an image continuously recorded on the recording sheet corresponding to the forefront one pitch as a reference image and compares the image data of a comparison image recorded later than the reference image with image data of the reference image to check for image defects.
