  • Patent number: 8322840
    Abstract: A pattern is formed by carrying out the steps of dropping curable ink linearly onto a substrate, curing the ink dropped onto the substrate, and depositing layers of ink by repeating a process of linearly dropping a predetermined amount of ink onto the cured ink and a process of curing the predetermined amount of ink. In the step of depositing layers of ink, the ink is dropped at dot pitch p that satisfies pmin?p when the ink is dropped at dot pitch p, and a minimum dot pitch for preventing the dropped ink from spreading beyond cured landing-position ink that is located at a landing position of the dropped ink is pmin.

  • Patent number: 8304656
    Abstract: A line pattern is formed on a substrate by performing a first step and a second step. In the first step, a liquid material containing a pattern formation material dispersed or dissolved therein is dropped onto the substrate and dried. In the second step, the liquid material is dropped onto a dried body that has been obtained by drying the liquid material in the first step. In the second step, the liquid material is dropped at a smaller ejection amount than that of the first step. Further, the pitch of dropping the liquid material onto the substrate in the first step and the pitch of dropping the liquid material onto the dried body in the second step are less than or equal to a jaggy generation limit.

  • Publication number: 20100247756
    Abstract: A lenticular print that allows stereoscopic viewing is formed by forming lenticular lenses, each having a convex sectional shape, on an image-recorded member, which has groups of parallax images arranged and written thereon. Each group of parallax images includes strips of parallax images. The lenticular lenses are formed correspondingly to the individual groups of parallax images. The lenticular print is formed through a base forming step of forming bases, which extend in a longitudinal direction of the parallax images and have a rectangular sectional shape and a predetermined height, of the lenticular lenses by depositing a transparent material on the groups of parallax images, and a lens forming step of forming lens top portions of the lenticular lenses by depositing the transparent material on the bases so that the deposited transparent material bulges upward from the bases due to surface tension thereof to have a substantially circular sectional shape.

  • Publication number: 20100078824
    Abstract: A method for forming a three-dimensional structure comprises: a first step of dropping a liquid material containing a structure-forming material and a solvent onto a structure forming surface; and a second step of drying at least a part of the solvent in the dropped liquid material to form a deposit layer on the structure forming surface, wherein the first step and the second step are repeated while a dropping position of the liquid material is shifted such that a next droplet of the liquid material is dropped onto the deposit layer formed of the previously-dropped liquid material to repeatedly accumulate the deposit layers on the structure forming surface, thereby forming a three-dimensional structure having at least one inclination portion inclined with respect to the structure forming surface.
