摘要:
A method for printing on a curved surface and a printed curved surface body using the method. The method includes the steps of: applying printing ink having a viscosity of 5-500 PaS, preferably 5-250 PaS, to a protrusion portion of a relief printing master plate 3 which is a flat plate with the protrusion portion 0.1-50 µm high, preferably 0.1-25 µm high in height h ; pressing a rubber or rubbery roll-like elastic blanket 2 having an elastic portion whose thickness T has a relation of 2H≤T≤8H with respect to a level difference H of a to-be-printed curved surface body 10 and which has a hardness (JIS A-scale) of 3-40, preferably 3-20, onto the relief printing master plate 3 supplied with the printing ink while applying constant pressure to the roll-like elastic blanket 2 and smoothly rotating the roll-like elastic blanket 2, so as to transfer the printing ink to an outer circumferential surface of the roll-like elastic blanket 2; and moving the roll-like elastic blanket 2 having the printing ink transferred thereto, and bringing the roll-like elastic blanket 2 into rotational pressure contact with a surface of the to-be-printed curved surface body 10 so as to perform printing thereon.

A method of manufacturing a printing blanket without wrinkles in a sheet is provided, the printing blanket including an elastic body and a sheet bonded to a surface thereof, the method being configured to press a surface of the sheet against a surface to be printed, to perform printing, and including: fixing the sheet at a periphery of a region of the sheet to be bonded to the elastic body; mounting the elastic body to oppose a bonding surface of the elastic body to a bonding surface of the fixed sheet; applying an adhesive to at least one of the bonding surface of the sheet or the bonding surface of the elastic body; and pressing the bonding surface of the sheet and the bonding surface of the elastic body against each other to bring the sheet into close contact with the elastic body through intermediation of the adhesive while stretching the sheet along the surface of the elastic body.

Sports equipment, particularly game balls, are printed with an ink cured with light in the visible region of the electromagnetic spectrum. The ink uses a photoinitiator that absorbs light in both the ultraviolet region and in a range of from about 400 nm to about 690 nm in the visible light region, a Type I photoinitiator compound absorbing in only the visible region, or a Type II photoinitiator compound either containing an abstractable hydrogen or used with a free radical-curable material comprising an abstractable hydrogen.

A fixture element (24) which enhances loading/unloading of a ball (B) relative thereto while promoting supporting engagement with and positioning of the ball to allow an image to be imprinted on an outer spherical surface thereof by a printing process requiring a predetermined area defined by the outer spherical surface of said ball to remain unobstructed during the printing process is disclosed. Such element includes a head portion (40) and a shaft portion (50) extending from the head portion. The head portion of the element defines a generally curved inner surface (46) extending thereacross and generally corresponding to a segment on the outer spherical surface of said ball. To increase the interface with the ball, the head portion of the element defines a plurality of circumferentially spaced wings (44) for positioning and supporting the ball engaged thereby for rotation about the axis of the element's shaft portion. When the element is rotated, the wings on the element trace a surface of revolution which extends into and across the predetermined area required for printing. The head portion of the fixture element is configured between the wings to engage, position and support the ball while remaining functionally removed from the predetermined area required for imprinting the image on the outer surface of the ball.

A method of using a jig printing system, the method comprising: positioning a print support portion (402) in a base plate (200) by aligning a plurality of alignment pins (404, 406) arranged on a bottom surface of the print support portion (402) with a plurality of receiving portions (224) of a grid in the base plate (200); securing an article (600) onto a first article maintaining jig (302), the article (600) extending over a processing aperture of the first article maintaining jig and having a first surface and an opposite second surface; positioning the first article maintaining jig (302) on the base plate (200), the print support portion (402) extending through at least a portion of the first article maintaining jig (402); and printing on the first surface of the article (600) in a location proximate the print support portion (402) that is supporting the article (600) at the second surface of the article (600).
摘要:
A printing method 100 includes causing, when pressing the printing blanket 20 formed of an elastic material and having a shape narrowed toward an end portion against an original plate 10 to which ink 2 is applied, the printing blanket 20 to descend at a lowest velocity at the moment when the end portion of the printing blanket 20 contacts the original plate 10, and increasing the velocity of descending as the printing blanket 20 is pressed further against the original plate 10. Likewise, when the printing blanket 20 is pressed against a surface to be printed 30, the printing blanket 20 is made to descend at a lowest velocity at the moment when the end portion of the printing blanket 20 contacts the surface to be printed 30, and the velocity of descending is increased as the printing blanket 20 is pressed further against the surface to be printed 30.
