A printed layer forming apparatus for a cover glass of a display device includes: a printing member including a first main body and a projection extending from one surface of the first main body, the projection having a thickness less than that of the first main body; and a cleaning member including a second main body, a first sidewall, and a second sidewall spaced apart from and opposing the first sidewall defining a space into which the projection is insertable to remove ink.

A method of printing radiopaque indicia on a medical device. The method includes applying radiopaque marking fluid to a surface of a plate comprising one or more etchings having a depth of at least 0.0001 inches, exposing the radiopaque marking fluid on the surface of the plate to air to allow the radiopaque marking fluid to achieve a sufficient level of tackiness, and transferring the radiopaque marking fluid to a medical device. The radiopaque marking fluid comprises a clear ink and tungsten particulates having a particulate size of more than one micron.

Disclosed is a system for marking eggs by stamping and printing thereon.

The present invention generally relates to a printed paper straw, process of manufacturing, and method of use. The present invention also relates to a package of straws that are uniquely identifiable by an easy-to-read text or drawings located on the external surface of each straw.

A pad printing device for printing a window of a display device includes a pad to transfer ink to the window. The pad includes a printing portion to transfer the ink to the window by being pressed against the window and a body portion disposed on the printing portion and to apply a pressure to the printing portion. A hardness of the printing portion is less than a hardness of the body portion, and a sidewall of a portion of the pad where the printing portion contacts the body portion is substantially perpendicular to the window.

Provided is an activation device for a printing blanket and a printing method using a printing blanket that enable a surface of an absorber to be constantly kept clean to enable proper activation of a surface of the printing blanket. The activation device for a printing blanket includes a storage tank having a box shape, the absorber mounted on the storage tank, and a liquid stored in the storage tank. The absorber includes layers of absorbing members and absorbs the liquid from an absorber lower part, and an uppermost layer of the absorber is peelable from the absorber.

Provided are a printing blanket and a printing method that enable printing on a printing member having a curved surface at an edge. The printing blanket includes a base member made of an elastic material having a three-dimensional shape with a recessed portion or a hole portion in a center of the base member and a ridge line surrounding the recessed portion or the hole portion, and a printing surface arranged on a surface of the base member on an outer side from the ridge line.

The invention relates to a pad printing instrument comprising an ink supply system capable of control the temperature, viscosity and colorant concentration of an ink in an ink cup. Such controls are achieved by continuously adding and mixing a cold ink having a composition identical to the ink in the ink cup but having a lower temperature. The continuous addition of a small amount of a cold ink into the ink cup could compensate heat generated by the friction between the ink cup and a clich and could minimize the evaporation of a diluent in the ink and change in the concentration of colorants in the ink and ink viscosity. The invention also relates to use of a pad printing instrument comprising an ink supply system of the invention for producing colored hydrogel or silicone hydrogel contact lenses.

A machine for manufacturing printed laminated films, particularly for packaging, which comprises a frame that supports elements of traction of at least one primary film along an advancement path and elements of printing the primary film which are interposed along the advancement path. On the frame there are, in mutual succession, downstream of the printing elements, along the advancement direction of the primary film, elements of laminating a secondary film to the primary film with the interposition of an adhesive material and elements of electron beam polymerization of the adhesive material.

Provided is a printing blanket that is unlikely to cause portions uncoated with ink even when the printing-applied surface has protrusions. The printing blanket according to an embodiment of the present invention includes a printing surface to be pressed against a printing plate on which the ink is placed and against the surface on which printing is applied and that is a target of printing. The printing blanket further includes a substrate, an inner coating layer covering at least part of the surface of the substrate, and an outer coating layer covering at least part of the surface of the inner coating layer that is on the side opposite the substrate. The inner coating layer has a smaller Asker C hardness than the substrate, and the outer coating layer has the printing surface on the side opposite the inner coating layer.
