Abstract: There are provided an ink jet printing apparatus that can appropriately set drying intensity and a drying intensity setting method thereof. An ink jet printing apparatus includes a printing section that prints an image on a sheet with aqueous ink by an ink jet method, an ink drying section that dries the ink by heating the sheet having been subjected to printing, and a varnish coating section that coats the sheet of which the ink has been dried with UV varnish. The drying intensity of the ink drying section is set so that temperature where the sheet reaches is in a prescribed range. Regions corresponding to the same drawing conditions are extracted from an image to be printed, and drying intensity is set on the basis of a drawing condition corresponding to the maximum occupied area among the regions.

Abstract: An image-forming device includes a printing portion that forms images on the media being transported using ink, a varnish application portion that applies aqueous varnish to the media on which the images are formed, a treatment portion that performs a treatment on the media so that a stickiness evaluation value which is a stickiness evaluation value indicating a degree of stickiness of the aqueous varnish applied to the media when the media to which the aqueous varnish is applied are output from the varnish application portion and is derived using a damped vibration percentage of a pendulum caused to do pendulum motions from an arbitrary location of the media to which the aqueous varnish is applied as a pivot reaches 0.24 or less, and an accumulation portion that accumulates the media to which the aqueous varnish is applied and on which the treatment is performed.
