A paper holding mechanism on the cylinder of a cylinder screen printing machine said paper holding mechanism being formed by clips which are controlled by a stationary cam by means of which the clips can be swung in and out of the operative position as well as by a rotating cam controlling the opening and closing of the clips which cam rotates with a speed such that during a complete working stroke and return stroke said cam has made two revolutions, said rotating cam having two opposite cam surfaces by means of which the clips can be moved against the cylinder surface so that also during part of the return stroke the clips do not extend outside of the cylinder surface.

A pressure applying element, a sheet to be printed, and an ink ribbon, an interchangeable form carrying printing indicia, and a pressure absorption plate are arranged in vertical sequence to be pressed together by the pressure applying element in the printing process whereby the pressure absorption plate absorbs the applied pressure, the ink ribbon being wound on a delivery spool and a wind-up spool mounted for rotation in a cassette housing, the cassette housing forming a guide delivering ribbon from the delivery spool about one free edge of the pressure absorption plate, transversely across the pressure absorption plate in spaced relation thereto, about the opposite free edge of the pressure absorption plate and to the wind-up spool, the cassette being removeable from and insertable in the press in a direction parallel to the spool rotational axes and the free longitudinal edges of the pressure absorption plate.

It is aimed to suppress the influence of a positional deviation occurring in bringing two plate bodies aligned in advance into contact in a transfer apparatus for bringing two plate bodies into contact by pressing by a roller member. Alignment mechanisms 71 are mounted on a main frame 10 and an alignment stage 36 is mounted on the alignment mechanisms 71. A lower stage block 3, a transfer roller block 4 and a roller travel driver 5 are placed via a detachable stage 37 on the alignment stage 36. A positional relationship between a blanket BL held on a lower stage 31 and a transfer roller 431 for pushing up the blanket BL does not vary by an alignment adjustment. Thus, the influence of a positional deviation, a magnitude of which changes according to the amount of deflection of the blanket BL, can be suppressed.

The present application relates to a roll printing apparatus and a roll printing method using the same, and the roll printing apparatus according to the present application comprises a printing roll support, a printing roll, a blanket which is provided on an outer surface of the printing roll, a coater which coats a surface of the blanket with ink, a cliche, and a printing object, in which the printing roll is provided to be fixed to the printing roll support so as to perform rotational motion, and the cliche is conveyed by the rotational motion of the printing roll.
摘要:
A method of achieving precision registration in a roll to roll process by simultaneously depositing multiple inks onto a printing roll. One of these inks prints a pattern of fiducial marks onto a substrate while another ink prints a predetermined pattern on the same substrate such that the predetermined pattern bears a predictable spatial relationship to the pattern of fiducial marks. Consequently, even if the ink forming the predetermined pattern is invisible, or has such low contrast with the substrate that it is effectively invisible, or even has been dissolved away in a subsequent processing step, it is still possible to know where the predetermined pattern is by referring to the pattern of fiducial marks.
摘要:
A method for forming a pattern of continuous lines with a line width of 20 microns or less (FIG. 4B) of a printable material composition (20) on a receiver element (70) includes providing an elastomeric relief element (60) and forming a relief pattern of a series of non-overlapping or discontinuous raised pixel features (FIGS. 10A-10D) on the elastomeric relief element (60). The printable material composition (20) is applied to the uppermost relief surface of the elastomeric relief element (60) and the pattern of printable material composition (20) is transferred from the uppermost relief surface to a surface of the receiver element (70).
