摘要:
In a rotary screen device (200) in which ink is transferred through holes of a screen (202), with a rotary screen cylinder provided with the screen (202) being rotated, to carry out printing, the rotary screen cylinder is stopped, in accordance with a stop signal, at a position at which a pattern-free portion (a hole-free portion) (A) of the screen (202) comes to a lowermost position. Since the rotation of a stencil printing press (20e) is stopped in a rotation phase in which the pattern-free portion (A) of the screen (202) comes to the lowermost position, ink is prevented from dripping through the holes of the screen (202).
摘要:
A carousel and station-based printing system for textiles comprises one or more stations with a digital printing apparatus and optionally other stations with a stencil printing apparatus. The system allows for high speed printing of images having details of high resolution, rich colors, or variability, optionally also comprising a wetting apparatus operative to wet at least a part of the printed object prior to the digital printing.
摘要:
There is disclosed a stencil printing method carried out by employing a stencil printing machine comprising: a drum (26) which is rotatable and has a outer peripheral wall (53) formed by an ink impermeable member and in which a stencil sheet (18) is mounted on a surface of the outer peripheral wall (53); an ink supply device (54) which has an ink supply unit (55A) provided on the outer peripheral wall (53) of the drum (26) and supplies ink (56) on the surface of the outer peripheral wall (53) from the ink supply unit (55A); and a pressure roller (35) which presses a fed print medium (37) onto the outer peripheral wall (53); the method comprising: a step of mounting a stencil sheet (18) on the drum (26); a step of platemaking the stencil sheet (18); and a step of transferring a water-based ink (56) to a print medium (37) by making the water-based ink (56) pass through perforations of the stencil sheet (18).
摘要:
A method for controlling thermal energy of a thermal head depending on the surface state of a stencil paper in a thermal head controller controlling thermal energy of the thermal head for punching a stencil paper fed out from a stencil paper roll. Residual quantity of the stencil paper M of a stencil paper roll (21b) is calculated by a means (65) for calculating the residual quantity, the time elapsed after production of the stencil paper roll is acquired based on the data of production date stored in the storage section (70) of the stencil paper roll (21b), data of the type of stencil paper stored at the storage section (70) is also acquired, thermal energy is then determined based on the residual quantity, the elapsed interval and the type data and thermal operation of the thermal head (22) is controlled based on the thermal energy.
摘要:
A stencil printing machine includes a drum which is rotatable and has an outer peripheral wall formed by an ink impermeable member and in which a stencil sheet is mounted on a surface of the outer peripheral wall. An ink supply device has an ink supply unit at a printing position upstream of a maximum printing area of the outer peripheral wall of the drum and supplies ink on the surface of the outer peripheral wall from the ink supply unit. A pressure roller presses a fed print medium onto the outer peripheral wall.
