Method and apparatus for ink jet printing on textile products

An object is to provide superior inkjet embossed products in image quality such that inkjet embossing towards the genres meets the various conditions related to density, resolution, blurring, dot graininess. To achieve this object, when an image is formed by a number of dots obtained by discharging the ink from a stamping head to fix the ink on the sorts, the amount of ink discharged from the print head into the fabrics is controlled to produce ink-jet printed products so that the average value of the equivalent circle diameter for each point after image formation can be after four-quarters or less than the average value of the fiber diameters that make up the genera. Thus, excellent ink jet stamped products can be obtained in image quality, with reduced smudging and high dot graininess.
