摘要:
The present invention relates to a printed substrate comprising a substrate and a printing ink and is characterized in that at least one side of the substrate has a surface with such porosity that the Gurley-Hill air permeability value of the substrate is above 7000 s/100 ml, and it comprises an printing ink formulated as heat-set offset printing ink with reduced tack comprising at least one pigment and a mixture of at least two solvents boiling in the range of from 200° C. to 270° C.

The present invention relates to a printing method by an offset printing press and an offset printing press and has an object to carry out a substrate process for low-whiteness printing paper such as paper for newspaper with substrate treatment agent and to enhance the print quality while preventing appearance of muddiness in printing ink by the substrate treatment agent. The present invention is configured such that substrate treatment agent such as low-whiteness enhancement agent is supplied to a printing face of printing paper, and thereafter the substrate treatment agent supplied to the printing face is dried and then offset printing is carried out for the printing paper by a printing apparatus.

The specification pertains to a single or multiple coated printing sheet in particular but not exclusively for sheet-fed offset printing with an image receptive coating layer on a paper substrate. The printing sheet has the property that it can be printed in an offset printing process without spraying a fine powder, usually called offset powder or dust powder, on the sheet as it comes off the press to prevent the ink from transferring to the back side of the next sheet. Also irradiative (UV or IR) drying on the sheet fed press is not necessary and/or the use of overprint varnish is not required. In addition to that, unexpectedly short times until reprinting and converting can be achieved. Furthermore methods for making such a printing sheet and uses of such a printing sheet are disclosed.

A printing apparatus adapted for printing wide line width and narrow line width patterns with one printing plate when fabricating a liquid crystal display device is disclosed. The printing apparatus includes a printing roll having target pattern forming material spread thereon, a printing substrate have at least one pair of adjacent printing plate patterns and at least one barrier rib pattern therebetween, and a target substrate. The printing substrate is configured to receive target pattern forming material from the printing roll and the target substrate is configured to receive target pattern forming material remaining on the printing roll following transfer of target forming material to the printing substrate.
摘要:
An offset printing process comprising the steps of: applying a hydrophilic phase to a printing plate with or without an oleophilic phase, the hydrophilic phase comprising at least one catalytic species, and applying the hydrophilic phase applied to the printing plate to a receiving medium thereby realizing in a single step a functional pattern of the at least one catalytic species on the receiving medium, wherein, if the hydrophilic phase is applied with the oleophilic phase, the oleophilic and hydrophilic phases are either applied separately from an ink and a fountain medium or are applied together in the form of a single fluid ink, the single fluid ink consisting of a dispersing phase and a dispersed phase, and the hydrophilic phase is exclusive of an ionomer.
摘要:
An improved method of fabricating integrated circuits, particularly active matrix arrays. The present method comprises applying an etch-resist pattern to an integrated circuit by printing to form resist patterns. The circuit is then etched, recoated with a different substance, a new ink pattern applied and the pattern repeated to form the successive layers of the integrated circuit.

A flat-bed press having a carriage (4) which includes an ink roller (7) and a blanket (5), and which is adapted to be moved on a press body frame (1) provided with an inking unit (3) at at least one end thereof, characterized in that the press body frame (1) is provided therein with a table (10) on which the materials (12) to be printed are placed, a feed head (21) having suckers (22) for retaining thereon a material (12) to be printed, and a transfer means (23) for moving the feed head (21) and carrying the material (12) to be printed which is retained on the suckers (22) to a paper bed (9).
摘要:
In an off-set printing device suited to multi-colored printing the printing plate support and the printing carrier support are arranged on a common carrier plate between two parallel racks connected with the carrier plate and extending in the printing direction. The printing roller is freely removable from the carrier plate and has at each of its axial ends a spur gear or pinion for engagement with an associated one of the racks, and the roll of the printing roller is freely rotatable relative to a shaft provided with hand grips. On the carrier plate--in the printing direction--in front of the printing plate support and on the printing roller at least one projection and a complementary recess are provided which in the presenting of the printing roller to the carrier plate engage with one another.
