An aqueous inkjet printer also ejects drops of UV material on an aqueous ink image and exposes the aqueous ink image and the UV material to UV radiation before passing the aqueous ink image and UV material through a thermal dryer. The exposure to UV radiation pins the UV material to the aqueous ink image and underlying substrate and the thermal dryer fixes the aqueous ink image to the substrate while releasing free radicals from the UV material. Thus, the printer produces textured prints that do not have free radicals that can irritate skin or produce noxious odors.

A boiling point (C) of the low-molecular weight carboxylic acid and a boiling point (D) of the aqueous solvent satisfy the following relational formula (I); and an acid dissociation exponent pKa (C) of the low-molecular weight carboxylic acid and an acid dissociation exponent pKa (B) of an acid group in the polymer dispersant satisfy the following relational formula (II):

boiling point (C)>boiling point (D)   (I), and

pKa (C)<pKa (B)   (II).

A networked product imaging system includes devices that provide the production of imaged goods. Sellers are easily integrated into the network with minimal or no inventory requirements. Customer requirements are provided to a central computing device (CCD) that has two-way communication with a plurality of geographically separated product image forming devices. The central computing device determines specifications for forming the image on the blank product in accordance with the customer's order. The central computing device selects a product image forming device from the plurality of geographically separated product forming devices for fulfilling the order, based upon factors that include the specification of the product image forming device available, the product image forming inventory and the blank product inventory available at the geographic location of the product image forming device. The selected product image forming device forms the image on the blank product at the remote location.
