The present invention relates to [1] a process for producing a printed material, including step 1 of subjecting an image-bearing surface of a printed recording medium 1 on which characters or images are formed by analog printing to discharge treatment under specific conditions to obtain a printed recording medium 1, and step 2 of further forming characters or images on the image-bearing surface of the printed recording medium 1 by ink-jet printing using a water-based ink to obtain the printed material, [2] an ink-jet printing method including the step of ejecting a water-based ink onto a printed recording medium 1 by an ink-jetting method to form characters or images thereon, in which the printed recording medium 1 has an image-bearing surface on which characters or images are formed by analog printing, and the image-bearing surface is subjected to discharge treatment under the specific conditions, [3] a recording medium for ink-jet printing, including an image-bearing surface on which characters or images are formed by analog printing and which is subjected to discharge treatment, in which a surface free energy of the image-bearing surface after being subjected to the discharge treatment is not less than 30 mN/m, and [4] a printed material including an image-bearing surface on which characters or images are formed by analog printing and then on at least a part of which characters or images are further formed by ink-jet printing using a water-based ink, in which the image-bearing surface after forming the characters or images thereon by the analog printing is subjected to discharge treatment, and a surface free energy of the image-bearing surface after being subjected to the discharge treatment is not less than 30 mN/m.

An ink composition for high-speed screen printing, includes a solvent with a boiling point of not less than 170 C. at not less than 70 wt % of the total solvent, and a prepolymer or polymer with a weight-average molecular weight of not less than 2000 at not less than 7 wt % with respect to the total ink composition, and having a viscosity of not less than 6 Pa.Math.s and less than 30 Pa.Math.s as measured with a BH-type rotating viscosimeter at 25 C., and a thixotropic index (TI value) of 2.0 to 8.0, the measured flow radius value of 14.0 to 24.0 mm after 1 minute from the start of measurement by a flow property measuring method using a spread meter at 25 C. according to JIS K5701-1:2000.

The present disclosure relates to methods of printing graphene oxide (GO) and printed GO membranes. An embodiment of the present disclosure includes producing graphene oxide (GO) ink by mixing graphene oxide particles with a solvent. The GO ink can be inserted into a printer and the printer head can expel droplets of GO ink on the substrate. The GO ink can be dried on the substrate and the substrate can then be used for various applications including a medium for filtering water.
