Abstract:
According to example embodiments, a roll printing apparatus includes a cleaning device in which a cleaning nozzle unit and a spray nozzle unit are integrated so that both a reverse offset process and a cliche cleaning process may be achieved in the roll printing apparatus. The roll printing apparatus may include a base plate, a blanket roll to transfer an ink material to a cliche and a substrate, a blanket roll supporter located on the base plate to support the blanket roll, a cliche table located on the base plate to fix and move the cliche, a substrate table located on the base plate to fix the substrate, and the cleaning device installed on the base plate to clean the cliche. The cleaning device may include a cleaning nozzle unit to spray a cleaning solution and a spray nozzle unit to spray DIW, which are integrated.
Abstract:
The present invention relates to a reverse offset printing method, and more particularly, to a reverse offset printing method in a partial off type capable of accurately transferring a pattern to a cliche to achieve more precise minute printing by separately performing removal for each shear region of a functional ink even though the pattern is minute.
Abstract:
A printing apparatus for a cassette accommodating a recording medium such as a tape-shaped recording medium or the like or a cassette accommodating case includes a cylindrical member and a cylindrical pad. The cylindrical member is supplied with an ink which contains an inorganic filler having a comparatively large particle size. The ink is added with a titanate coupling agent or an aluminate coupling agent. The cylindrical member has the concave printing plate formed on its peripheral surface and is supported rotatably. The ink on the concave printing plate is transferred to the cylindrical pad. The cylindrical pad is supported rotatably. The cylindrical pad is brought in contact with the concave printing plate and the surface of the conveyed cassette accommodating the recording medium or the conveyed cassette accommodating case. The ink transferred to the cylindrical pad from the concave printing plate is transferred to the surface of the conveyed cassette accommodating the recording medium or the conveyed cassette accommodating case.
Abstract:
An offset printing head includes, mounted to rotate parallel to each other and spaced from each other on a common carriage that is itself mounted to be mobile in translation on a frame, an inking roller and a blanket cylinder. As it moves to and fro, the carriage sweeps across a plate support which receives a plate and an object support which receives an object to be printed. The inking roller and/or the blanket cylinder are each driven by an individual drive system specific to it and independent of the movement of the carriage. Applications include printing machines combining an offset printing head with a silkscreen printing head.
Abstract:
In a process and apparatus for printing on flat individual articles such as CDs by means of offset printing, the surface to be printed upon and the offset printing cylinder which is rolled against the article are adjusted relative to each other to produce a pressure effect which is favorable to transfer of the print image on to the article in order to compensate for differences in thickness between the individual articles. When adjusting the printing cylinder and the surface to be printed upon relative to each other, the radial position of transfer surfaces at the periphery of the printing cylinder may, if necessary, be taken into account. In the absence of an article in the printing station, it is possible to provide a replacement article in the form of a web of material, on to which the print image intended for the missing article is transferred from the printing cylinder. The plate cylinders may also be adjusted relative to the offset printing cylinder in such a way as to permit adaptation to the radial position of the transfer surfaces at the periphery of the printing cylinder.
Abstract:
The method and apparatus for printing the side edges of sheet stacks, such as books, catalogs, and the like, wherein after the stack side edge has been trimmed and cut the stack sheets are maintained in relationship under slight compression within a belt conveyor using upper and lower belts. As the retained stack is translated through the printer a sensor senses the location of the stack leading edge initiating a timing circuit which controls a rotary printing head engageable with the stack side edge to print indicia upon the side edge at the desired location. The movement of the stack rotates the printing head and a dense high quality image is produced. In an embodiment of the invention, a plurality of printing heads are mounted upon the conveyor apparatus to print the stack edge, sequentially, with a plurality of colored ink.
Abstract:
An article printing system is disclosed wherein successive strips of closely-spaced interconnected articles, such as electronic components, are fed in an intermittent manner by an endless conveyor belt to a printing nip located beneath a continuously rotating offset roll which is arranged for synchronized vertical reciprocation. Belt perforations corresponding in location to each individual article to be printed are sensed by a photoelectric detector to stop the article at a ready position located a predetermined distance from the printing nip. When a printed image on the offset roll rotates to a position of predicted registration with the motionless article surface below, the belt is restarted and the offset roll is lowered to its printing position in order to transfer the image to the article as it traverses the printing nip. After the image has been transferred, the offset roll is restored to its upper retracted position to avoid premature frictional contact with the leading edge of the next article to be printed. The belt continues to move until detection of the next perforation stops the belt in preparation for another printing cycle. Additional pairs of perforations, distinguishable by their characteristic spacing from the perforations corresponding to individual articles, are sensed by a second photoelectric detector for stopping the system after an entire strip of articles has been printed in order to allow a new strip to be loaded onto the belt.
