A printing assembly for a printing machine comprises a drum mounted for rotary movement about an axis and supporting a plurality of object holders parallel to the drum axis and uniformly circumferentially spaced around the axis. A drum drive imparts continuous rotary movement. A printing station at the periphery of drum for printing successive objects in the course of displacement by the printing station. The printing station is carried by a beam and includes a screen and squeegee. A beam drive ...

A printing plate including a printing plate member, an easily deformable elastic layer laminated on the printing plate member, a surface layer having a higher elasticity than that of the elastic layer, laminated on the elastic layer, and a printing surface layer formed on the surface layer. The printing surface layer has an image area having an affinity with an ink and a non-image area having an ink repellancy.

Aqueous compositions, suitable for printing, are described which have a high volume solids content. They comprise primary polymer particles and a secondary polymer which provides temporary adherence of the particles to a substrate before the primary polymer is fused by a heating step, in a printing process, in order to cause permanent adherence. There are advantages over the use of organic solvent-based and other aqueous compositions, such as easier cleaning, low toxicity/fire hazard and lower c...

A printing apparatus and a printing method which eliminate a problem of boundary stripes by taking advantage of features of the multipass printing performed by the printing apparatus without causing a reduction in a throughput. An amount of paper feed for each scan is set to a value which, when multiplied by an integer, is not equal to a printing width covered by a total number of nozzles in a print head, in order to prevent the adjoining of the end portions of print areas of each scan which wou...

Printers selectively connected to a computer terminal device is identified. By controlling the printer using a dedicated correction data, a quality of the printing image is improved. As an identification data of the printer connected to the computer terminal device, a printer ID is checked. By reading the correction data corresponding to the printer ID, the head shading process is performed for the printer connected to the computer terminal device using the correction data.

A printing apparatus is provided for printing an image using sequentially transferring inks for a plurality of colors, which are repeatedly arranged on an ink ribbon (R) with each having a predetermined length (l), to an elongated recording sheet (T) so that the transferred inks are overlapped. The printing apparatus includes a data input section (12) for inputting a plurality of data items representing images to be printed, a control section (11, S1) for calculating each of print lengths (Ln) o...

In a print apparatus and method in which the print head having printing elements to form print dots is made to scan over a printing medium in a predetermined direction to form a printed image, the drive timing intervals between a plurality of dots formed in the scan direction by the same printing element are changed in a cycle smaller than a cycle in which a printed image variation appears, in order to eliminate the printed image unevenness that cyclically appears due to variations in the manufa...

A printing device (10) for a printing press (12) having a cylinder (14) having at least one journal (16 or 18) extending from an end (20 or 22) of the cylinder (14), and a bearing (30 or 32) on the journal (16 or 18) and having an inner edge (44 or 46) located in the range of 1/16 inches to 11/2 inches from the end (20 or 22) of the cylinder (14).

The present invention corrects variations in characteristics of each printing element of a printing head to print high-grade images. To achieve this, the present invention provides an ink jet printing head that uses thermal energy generated by a heat-generating resistor to eject an ink from an ink ejection opening, wherein a plurality of wirings with different wiring resistances are connected to the heat-generating resistor. A transistor selected one of the plurality of wirings to conduct curren...

Regarding filling of a paste, a temperature gradient at a paste-pressing face is managed by a heater incorporated in a filling head. Alternatively, a nonvolatile component is applied to a printing face of a base material before the paste is filled, thereby preventing a volatile component of the paste from evaporating with time. Viscosity of the paste is thus maintained. Meanwhile, a change of the quantity of the paste is coped with by changing a moving speed of the filling head or a contact angl...
