摘要:
A digital printer is provided with an automated printing sheet transport system, operating in an intermittent regime of feeding a printing sheet to the digital printer, halting the transport to allow printing onto the printing sheet while the printing sheet is maintained in a fixed position, and removing the printed sheet from the digital printer after printing. The digital printer may be combined with a screen print station, both operating on top of a single printing sheet transport system, to form an integrated multifunctional and hybrid printing press.

The invention relates to an electric discharge lamp comprising:—a light-transmissive ceramic discharge vessel (1) enclosing a discharge space (100)—a first and a second current conductor (2,3) entering the discharge vessel (1) and each supporting an electrode (4,5) in the discharge vessel (1);—a sealing compound (6) sealing the current conductors (2,3) in the discharge vessel (1) in a gas tight manner,—an ionizable filling comprising a rare gas and metal halide in the discharge vessel (1), both current conductors (2,3) extending from the sealing compound (6) to the exterior of the discharge vessel (1). According to the invention the sealing

A method is disclosed for making a module that can be used in an electric or electronic device such as a flat panel display, a light emitting diode or a photovoltaic cell. The figure shows as a preferred embodiment of the method of the present invention a schematic section of a panel consisting of three adjacent modules (liquid crystal display cells; only one is shown completely). The panel is obtained by assembling two substrates (2) and (8) which carry functional layer (3) and (9) respectively. The substrates are preferably flexible plastic foils. Thin glass sheets (1, 7) are laminated to the substrates (2, 8) so as to obtain an efficient barrier layer which protects the functional layers (3, 9) from mechanical damage, heat and degradation due to diffusion of oxygen or water vapor. The method is especially suitable for making flexible, low-weight flat panel displays, e.g. LCDs comprising a liquid crystal composition (6), spacers (4) and seals (5).
摘要:
An imaging element (15, 122) comprising on a lithographic base at least one radiation sensitive or heat-sensitive layer composition, is image-wise exposed to radiation or heat. The composition is such that when exposed and developed, a lithographic surface is formed. The exposed imaging element is then passed through a closed treatment cell (26, 64, 66) in a processing apparatus in which the imaging element is brought into contact with a single developing fluid (44, 124). The closed treatment cell (26; 64, 66) comprises a housing (24; 114) having an entrance (28; 116) and an exit (30; 118) each closed by a path-defining roller (32; 128) in contact with a reaction surface (33; 130) to form a nip (34; 136) therebetween, through which the plate path (36; 72) extends. Sealing means (38; 138, 139) seal each path-defining roller (32; 128) to the housing. Evaporation, oxidation and carbonization of the treatment liquid is significantly reduced and quality control of the plate is possible before mounting on a printing machine.
摘要:
A processing apparatus comprises at least one wet processing station followed by a dryer in which wet sheet material comes into contact with heated drying air. Sheet material is fed over a static support member which supports the sheet material during drying. A drying unit is positioned opposite to and extending across the support member in a transverse direction, thereby to define a drying space between the support member and the drying unit. Drying air is fed to the drying unit to pass out through a drying air exit into the drying space. The support member includes a plurality of openings to allow drying air to pass therethrough, to ensure that the air flow is substantially the same whether a sheet of photographic material is positioned on the support member or not, while minimising the generation of turbulence.

A printing master 12 is described which includes a printing element and a base 33, characterized in that base 33 is provided with one or more strain gauges 31 and electric connections for measuring electric resistance. In a preferred embodiment, the printing element is a plate having a printing surface 35, of which the back side 37 is laminated to base 33. The printing master 12 may have an optional adhesive layer 36 and/or protective layer 32. The registration of the printing master can be adjusted conveniently and accurately by measuring the resistance of the strain gauges.
摘要:
The thermal treatment unit comprises a housing (12) having an inlet (14) and an outlet (16) for the imaging element so positioned as to define a path (18) through the housing (12). A continuous surface (20), formed of heat conductive material, is positioned on one side of the path (18). Drive means (22) move the continuous surface (20) in synchronism with the imaging element (10) as it passes through the housing (12). The imaging element (10) is urged into heat conductive contact with the continuous surface (20) and a heat source (26) is provided on the far side of the continuous surface from the path. A more even transfer of heat to the imaging element (10) is thereby achieved.
