摘要:
A coater (100), which is capable of spot coating a layer thick enough to be palpable onto a transfer object, is provided with a first coating unit (120) and a second coating unit (130). The first coating unit (120) is provided with a first impression cylinder (121) and a rotary screen cylinder (122) for transferring a first varnish on one surface of a sheet (1). The second coating unit (130) is provided with a second impression cylinder (131) and a cylinder (132) for transferring a second varnish on the first varnish that has been transferred onto the one surface of the sheet. Palpable protrusions formed by transfer of the first varnish in the first coating unit (120) are covered by the second varnish in the second coating unit (130) while maintaining the shapes thereof.

A printing unit prints simultaneously on both surfaces of a paper sheet while a detecting unit detects printing conditions on both surfaces of the paper sheet. The printing unit includes: a blanket impression cylinder configured to hold and transport the paper sheet; and a blanket cylinder being lateral to the blanket impression cylinder and being in contact with the blanket impression cylinder. The transporting device includes: a transfer cylinder configured to receive the paper sheet from the blanket impression cylinder; and a delivery cylinder configured to receive the paper sheet from the transfer cylinder. The detecting unit includes: a first checking camera configured to detect the printing condition on one surface of the paper sheet transported by the transfer cylinder; and a second checking camera configured to detect the printing condition on the other surface of the paper sheet transported by the delivery cylinder.

A rotary screen printing press includes: a sub-frame supporting a screen plate with brackets interposed therebetween, the screen plate being formed in a cylindrical shape; a screen-plate engagement-disengagement cylinder configured to move the sub-frame between a print position and a retreat position; and supporting plates supporting a squeegee in such a way that the squeegee is engageable with and disengageable from the inner periphery of the cylindrical screen plate. The supporting plates are supported on the sub-frame.

A rotary screen printing press includes: a screen plate; a squeegee; squeegee supporting means for supporting the squeegee; and a worm and a worm wheel. The squeegee supporting means includes: a supporting plate swingably supported and supporting the worm and the worm wheel; an eccentric sleeve configured to adjust the position of the center of swinging movement of the supporting plate; and a contact surface and a screw configured to limit the direction of the movement of the supporting plate. The eccentric sleeve and the contact surface and screw cooperate with each other to move the tip of the squeegee along the tangent line of an impression cylinder at a position at which the screen plate and the squeegee contact each other.

A proof printing press includes an impression cylinder, a collecting cylinder, and a wiping roller, which are positioned relative to a plate cylinder such that a length of an outer circumference of the plate cylinder at a downstream side of a facing position P1 in a rotation direction of the plate cylinder is longer than a length in a circumferential direction of a mounting surface of the plate cylinder, where the length of the outer circumference of the plate cylinder extends between the facing position P1 where the plate cylinder faces the collecting cylinder and a facing position P2 where the plate cylinder faces the wiping roller, and that a length of the outer circumference of the plate cylinder at a downstream side of the facing position P2 in the rotation direction of the plate cylinder is longer than the length in the circumferential direction of the mounting surface of the plate cylinder, where the length of the outer circumference of the plate cylinder extends between the facing position P2 where the plate cylinder faces the wiping roller and a facing position P3 where the plate cylinder faces the impression cylinder.

An intaglio printing press includes: a first intaglio printing unit; a second intaglio printing unit; a dryer for drying a printed surface of a sheet subjected to printing by the first intaglio printing unit; a convertible unit which holds and conveys the sheet received from the first intaglio printing unit and passes the sheet to the second intaglio printing unit in such a way that a surface of the sheet to be subjected to intaglio printing by the second intaglio printing unit is switchable between one surface and another surface of the sheet; and a second skewing adjustment cylinder and a second circumferential adjustment cylinder which are disposed between the convertible unit and the second intaglio printing unit and which adjust a position of a pattern to be intaglio-printed on the sheet by the second intaglio printing unit.
