Abstract

<P>PROBLEM TO BE SOLVED: To provide a proof printer saving an installation space, facilitating the work for handling a printing plate and printing paper, and executing more accurate proof printing that is as approximate in a state to actual printing as possible. <P>SOLUTION: While the printing plate 30 and the printing paper 40 are moved by moving a plate support 18 in a plate support unit 11 and a paper support 25 in a paper support unit 20, a print of the printing plate 30 made to have a prescribed curvature, together with the plate support 18, is transferred onto the printing paper 40 when the printing plate 30 passes the outer surface of a transfer roller 13. Accordingly, the proof printing can be conducted for a plurality of kinds of printing plates 30 different in size and moreover the equipment can be manufactured inexpensively. Therefore it is advantageous in terms of cost and besides no problem as to the installation space occurs. Since the transfer is conducted with the printing plate made to have the prescribed curvature, an actual printed matter can be transferred in an original size. Thus an accurate proof printed matter is obtained and the accuracy of plate inspection can be improved. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

本発明は、印刷版の検査を行う際に用いる校正印刷装置に関する。   The present invention relates to a proof printing apparatus used when a printing plate is inspected.

従来より、印刷版を印刷機に装着して印刷を行う前に、印刷版が正確に作成されているか否かを検査する検版を行うようにしている。かかる検版では、作業者が目視により印刷版を検査することもあるが、例えば、多色印刷の場合には、画像を多色に分解して印刷版を作成しているため、各印刷版を単独で目視検査しても、不良や欠陥、特に、絵柄部分の見当不良を検知することが難しい。   2. Description of the Related Art Conventionally, before a printing plate is mounted on a printing machine and printing is performed, a plate inspection for inspecting whether the printing plate has been accurately produced is performed. In such plate inspection, the operator may visually inspect the printing plate. For example, in the case of multicolor printing, the printing plate is created by separating the image into multiple colors. It is difficult to detect defects and defects, in particular, imperfections in the pattern portion even if they are visually inspected alone.

このため、従来、校正印刷を行い、得られた校正印刷物を目視検査して印刷版の検版を行うようにしている。例えば、校正印刷機で機械的に校正印刷を行う場合は、印刷版をシリンダに巻き、フラットベッドに印刷用紙をセットするようにしている。或いは、手加工で校正印刷を行う場合は、印刷版をフラットな作業台の上に載置し、印刷用紙を印刷版に上から被せて、転写を行うようにしている。

For this reason, conventionally, proof printing is performed, and the obtained proof print is visually inspected to inspect the printing plate. For example, when proof printing is mechanically performed with a proof printing machine, a printing plate is wound around a cylinder and printing paper is set on a flat bed. Alternatively, when proof printing is performed manually, the printing plate is placed on a flat work table, and the printing paper is placed on the printing plate from above to perform transfer.

しかしながら、機械的に校正印刷を行う手段の場合には、印刷版の大きさは種々異なっているのに対して、使用する校正印刷機のシリンダ径は決まっているため、特定の大きさの印刷版の場合しか、校正印刷機のシリンダに巻きつけられない。即ち、大きさの異なる複数種類の印刷版について校正印刷することはできない。また、校正印刷のためだけに、異なる径のシリンダを予め備えることはコスト的に著しく不利であるばかりか、設置スペースの問題も生じる。   However, in the case of means for performing calibration printing mechanically, the printing plate size varies, while the cylinder diameter of the calibration printing machine to be used is fixed, so that printing of a specific size is possible. Only in the case of the plate, it can be wound around the cylinder of the proof press. In other words, proof printing cannot be performed for a plurality of types of printing plates having different sizes. In addition, it is not only extremely disadvantageous to provide cylinders with different diameters in advance for proof printing, but also a problem of installation space arises.

手作業で校正印刷を行う手段の場合には、印刷版を作業台の上に載置し、かつ、印刷用紙を印刷版の上に被す作業を行うには、印刷版が極めて小さいものでない限り無理であり、多くの場合、複数人による作業になってしまう。また、印刷版と印刷用紙の両方がフラットの面で校正印刷されるため、実際の印刷機における印刷の状態とは異なってしまう。即ち、実際の印刷機はそのシリンダに印刷版を巻いて行うため、フラットな面で印刷したのでは、実際の印刷物と同じ寸法精度での転写は不可能であり、正確な校正印刷物が得られず、検版の精度の点で問題があった。特に、印刷版を作成して、検版を行う会社と、印刷を行う会社とが相違すると、印刷を行う会社での印刷物に不都合があった場合に、印刷版の修正のため、その都度、印刷を行う会社から印刷版を作成する会社へと大きな印刷版を運搬すると共に、再び納品を行う必要があった。また、フラットな作業台を用いるため、占有面積が大きく、設置スペースを広く必要とする。   In the case of means for manually performing proof printing, the printing plate is not very small for placing the printing plate on the work table and covering the printing paper on the printing plate. It is impossible as much as possible, and in many cases, it is a work by multiple persons. In addition, since both the printing plate and the printing paper are proof printed on a flat surface, the printing state in an actual printing machine is different. In other words, since an actual printing press winds a printing plate around its cylinder, printing with a flat surface is impossible to transfer with the same dimensional accuracy as the actual printed matter, and an accurate proofed printed matter can be obtained. However, there was a problem in the accuracy of plate inspection. In particular, if the company that creates the printing plate and inspects it is different from the company that performs printing, if there is a problem with the printed material at the company that performs printing, in order to correct the printing plate, It was necessary to transport the large printing plate from the printing company to the company that produces the printing plate and to deliver it again. Further, since a flat work table is used, the occupation area is large and a large installation space is required.

そこで、本発明では、上記した従来の問題点に鑑み、装置の小型化を図り、設置スペースが小さくて済み、印刷版と印刷用紙の取扱作業を容易にできると共に、実際の印刷状態にできるだけ近いより正確な校正印刷を行うことができ、しかも製作コストも安価な校正印刷装置を提供することを課題とする。   Therefore, in the present invention, in view of the above-described conventional problems, the apparatus can be reduced in size, installation space can be reduced, handling work of the printing plate and printing paper can be facilitated, and as close as possible to the actual printing state. It is an object of the present invention to provide a proof printing apparatus that can perform proof printing more accurately and that is inexpensive to manufacture.

The proof printing apparatus of the present invention has a plate support unit and a paper support unit, and moves the plate support in the plate support unit and the paper support in the paper support unit to move the printing plate and the proof printing paper. , The printing plate of the printing plate having a predetermined curvature is transferred onto the printing paper together with the plate support when passing through the outer surface of the transfer roller in the plate supporting unit of the printing plate.

図1に基づき本発明の一実施形態に係る校正印刷装置を説明する。この校正印刷装置1の図示しない本体フレームには、版支持ユニット11と紙支持ユニット20とが配設されており、該本体フレームには、版支持ユニット11と紙支持ユニット20との作動を制御する制御部を内蔵した図示しない制御盤が設けられている。上記の版支持ユニット11は、この図では、下部位置に配置されており、本体フレームに回転自由に支持される複数(本実施形態では6つ)のローラ12〜17と、表面に印刷版30を支持し、6つのローラ12〜17間を周方向に移動可能に設けられるシート状の版支持体18とを備えている。この場合、各ローラ12〜17はその回転軸が互いに略平行となるように配設され、かつ、ローラ12〜17同士が側面から見て多角形状をなすような位置関係で配設される。また、後述するタイミングベルト19a,19bに一定に張力を作用させるテンションローラとして機能するローラ17がローラ12,16間位置に配設される。   A proof printing apparatus according to an embodiment of the present invention will be described with reference to FIG. A plate support unit 11 and a paper support unit 20 are disposed on a body frame (not shown) of the proof printing apparatus 1, and the operations of the plate support unit 11 and the paper support unit 20 are controlled on the body frame. There is provided a control panel (not shown) including a control unit for performing the above-described operation. In the drawing, the plate support unit 11 is disposed at a lower position, and a plurality of (six in this embodiment) rollers 12 to 17 that are rotatably supported by the main body frame, and a printing plate 30 on the surface. And a sheet-like plate support 18 provided between the six rollers 12 to 17 so as to be movable in the circumferential direction. In this case, each roller 12-17 is arrange | positioned so that the rotating shaft may become substantially parallel mutually, and the rollers 12-17 are arrange | positioned by the positional relationship which makes polygonal shape seeing from a side surface. A roller 17 that functions as a tension roller that applies a constant tension to timing belts 19a and 19b, which will be described later, is disposed at a position between the rollers 12 and 16.

各ローラ12〜17の両端部にはそれぞれタイミングプーリ部a,bが設けられ、一方の端部のタイミングプーリ部aにはタイミングベルト19aが巻き掛けられ、他方の端部のタイミングプーリ部bにはタイミングベルト19bが巻き掛けられている。なお、タイミングプーリ部a,b、タイミングベルト19a,19bに代えて、スプロケット、チェーンを用いても良い。   Timing pulley portions a and b are provided at both ends of each of the rollers 12 to 17, a timing belt 19a is wound around the timing pulley portion a at one end, and the timing pulley portion b at the other end. The timing belt 19b is wound around. Note that sprockets and chains may be used instead of the timing pulley portions a and b and the timing belts 19a and 19b.

複数のローラ12〜17のうちの任意のローラ、本実施形態ではローラ13の回転軸には、図示しない回転モータ等の回転駆動手段が連結され、該回転駆動手段の回転駆動により、ローラ13が回転駆動され、その回転駆動力はタイミングベルト19a,19bを介して各タイミングプーリ部a,bに伝達されて、全てのローラ12〜17が回転される。なお、ローラ13は転写用ローラとして構成されている。   A rotation driving means such as a rotation motor (not shown) is connected to an arbitrary roller of the plurality of rollers 12 to 17, in this embodiment, the rotation shaft of the roller 13, and the roller 13 is rotated by the rotation driving of the rotation driving means. The rotational driving force is transmitted to the timing pulley portions a and b via the timing belts 19a and 19b, and all the rollers 12 to 17 are rotated. The roller 13 is configured as a transfer roller.

そして、上述した版支持体18は、例えば、ゴム等の可撓性のあるシート状の素材から方形状に形成されており、左右の両端部が上記左右のタイミングベルト19a,19bに固定取付され、タイミングベルト19a,19bの移動によって、各ローラ12〜17の外面を通過しながら図1の矢印で示す版支持ユニット11の周方向に回転移動される。この場合、版支持体18の転写用ローラ13の外面通過時に、該版支持体18の曲率が所定の曲率に制御されるようになっている。   The plate support 18 described above is formed in a rectangular shape from a flexible sheet-like material such as rubber, for example, and both left and right end portions are fixedly attached to the left and right timing belts 19a and 19b. By the movement of the timing belts 19a and 19b, the plate belt is rotated in the circumferential direction of the plate support unit 11 indicated by the arrows in FIG. 1 while passing through the outer surfaces of the rollers 12-17. In this case, the curvature of the plate support 18 is controlled to a predetermined curvature when the plate support 18 passes through the outer surface of the transfer roller 13.

The plate support 18 that passes through the outer surface of the plate support 18 can be pushed out by adjusting the axial position. The position-variable tension rollers 12 and 14 are freely slidable in a direction perpendicular to the axis, and are slid by a sliding means such as a cylinder (not shown) and fixedly held at an arbitrary sliding position. The curvature adjusting member is not limited to the position variable tension rollers 12 and 14, but may be other members.

一方、紙支持ユニット20は、本実施形態では、上記版支持ユニット11に対して相対的に上部位置に配置されており、本体フレームに回転自由に支持される複数(本実施形態では4つ)のローラ21〜24と、表面に印刷用紙40を支持し、4つのローラ21〜24間を周方向に移動可能に設けられるシート状の紙支持体25とを備えている。各ローラ21〜24はその回転軸が互いに略平行となるように配設され、ローラ21〜24同士が側面から見て略多角形状をなすような位置関係で配設される。また、後述するタイミングベルト26a,26bに一定に張力を作用させるテンションローラとして機能するローラ24がローラ21,23間位置に配設される。   On the other hand, in the present embodiment, the paper support unit 20 is disposed at an upper position relative to the plate support unit 11, and a plurality of (four in the present embodiment) are rotatably supported by the main body frame. Rollers 21 to 24, and a sheet-like paper support 25 that supports the printing paper 40 on the surface and is provided so as to be movable between the four rollers 21 to 24 in the circumferential direction. Each roller 21-24 is arrange | positioned so that the rotating shaft may become substantially mutually parallel, and rollers 21-24 are arrange | positioned by the positional relationship which makes a substantially polygonal shape seeing from a side surface. A roller 24 that functions as a tension roller that applies a constant tension to timing belts 26a and 26b, which will be described later, is disposed between the rollers 21 and 23.

版支持ユニット11と同様に、各ローラ21〜24の両端部にはそれぞれタイミングプーリ部a,bが固定され、一方の端部のタイミングプーリ部aには一方のタイミングベルト26aが巻き掛けられ、他方の端部のタイミングプーリ部bには他方のタイミングベルト26bが巻き掛けられている。なお、この場合も、タイミングプーリ部a,b、タイミングベルト26a,26bに代えて、スプロケット、チェーンを用いても良い。任意のローラ、本実施形態ではローラ23の回転軸には、回転モータ等の回転駆動手段が連結され、該回転駆動手段の回転駆動により、該ローラ23が回転駆動され、その回転駆動力はタイミングベルト26a,26bを介して各タイミングプーリ部a,bに伝達されて、全てのローラ21〜24が回転される。また、ローラ23は、版支持ユニット11の転写用ローラ13と外面同士が対向する被転写用ローラとして構成されている。   As with the plate support unit 11, timing pulleys a and b are fixed to both ends of the rollers 21 to 24, respectively, and one timing belt 26a is wound around the timing pulley a at one end. The other timing belt 26b is wound around the timing pulley b at the other end. Also in this case, sprockets and chains may be used in place of the timing pulley portions a and b and the timing belts 26a and 26b. A rotation driving means such as a rotation motor is connected to a rotation shaft of an arbitrary roller, in this embodiment, the roller 23, and the rotation driving force of the rotation driving means is rotated. All the rollers 21 to 24 are rotated by being transmitted to the timing pulley portions a and b through the belts 26a and 26b. The roller 23 is configured as a transfer roller whose outer surfaces face the transfer roller 13 of the plate support unit 11.

そして、上述した紙支持体25も、版支持体18と同じようにゴム等の可撓性のあるシート状の素材から方形状に形成されており、左右の両端部が上記左右のタイミングベルト26a,26bに固定取付され、タイミングベルト26a,26bの移動によって、各ローラ21〜24外面を通過しながら図1の矢印で示す紙支持ユニット20の周方向に回転移動される。   The paper support 25 described above is also formed in a rectangular shape from a flexible sheet-like material such as rubber like the plate support 18, and the left and right timing belts 26a are formed at both left and right ends. 26b, and is rotated and moved in the circumferential direction of the paper support unit 20 indicated by the arrows in FIG. 1 while passing through the outer surfaces of the rollers 21 to 24 by the movement of the timing belts 26a and 26b.

次に、かかる校正印刷装置1を用いた校正印刷方法について説明する。先ず、版支持ユニット11における版支持体18の表面に印刷版30を支持すると共に、紙支持ユニット20における紙支持体25の表面に印刷用紙40を支持する。この場合、例えば、図1に示すように、印刷版30並びに印刷用紙40の上下の両端部に支持棒30a,40aを予め取り付けておき、この支持棒30a,40aの両端部を版支持体18の表面並びに紙支持体25の表面に予め取り付けておいた支持環18a,25aに差し込んで係合し、印刷版30並びに印刷用紙40を支持する。   Next, a proof printing method using the proof printing apparatus 1 will be described. First, the printing plate 30 is supported on the surface of the plate support 18 in the plate support unit 11, and the printing paper 40 is supported on the surface of the paper support 25 in the paper support unit 20. In this case, for example, as shown in FIG. 1, support bars 30 a and 40 a are attached in advance to the upper and lower ends of the printing plate 30 and the printing paper 40, and both ends of the support bars 30 a and 40 a are attached to the plate support 18. The printing plate 30 and the printing paper 40 are supported by being inserted into and engaged with the support rings 18a and 25a previously attached to the surface of the paper support 25 and the surface of the paper support 25.

印刷版30並びに印刷用紙40をセットしたならば、本体フレームに付設された制御盤を操作して、2つのユニット11,20における回転駆動手段を駆動させると、両ユニット11,20における全てのローラ12〜17,21〜24が回転し、タイミングベルト19a,19b、26a,26bの移動によって、印刷版30が各ローラ12〜17の外面を通過しながら版支持ユニット11の周方向に回転移動され、移動途中でインキ供給手段により自動で或いは手動でインキが供給されると共に、印刷用紙40が各ローラ21〜24外面を通過しながら紙支持ユニット20の周方向に回転移動される。   When the printing plate 30 and the printing paper 40 are set, when the control panel attached to the main body frame is operated to drive the rotation drive means in the two units 11 and 20, all the rollers in both the units 11 and 20 are driven. 12-17 and 21-24 rotate, and the printing plate 30 is rotated in the circumferential direction of the plate support unit 11 while passing through the outer surfaces of the rollers 12-17 by the movement of the timing belts 19a, 19b, 26a, 26b. During the movement, the ink is supplied automatically or manually by the ink supply means, and the printing paper 40 is rotated in the circumferential direction of the paper support unit 20 while passing through the outer surfaces of the rollers 21 to 24.

そして、印刷版30と印刷用紙40とは、それぞれのユニット11,20における転写用ローラ13と被転写用ローラ23の外面を互いに接触しながら通過し、そのときに、版支持体18と共に所定の曲率となった印刷版30の版画が印刷用紙40に転写される。なお、インキ供給手段としては、例えば、図1に示すように、ローラ16と対向して設けたインキ供給ローラ70から構成することができ、印刷版30がローラ16とインキ供給ローラ70との間を通過するときに、印刷版30にインキが塗布される。   The printing plate 30 and the printing paper 40 pass through the outer surfaces of the transfer roller 13 and the transfer roller 23 in the respective units 11 and 20 while being in contact with each other. The print of the printing plate 30 having the curvature is transferred to the printing paper 40. As shown in FIG. 1, for example, the ink supply means can be constituted by an ink supply roller 70 provided facing the roller 16, and the printing plate 30 is disposed between the roller 16 and the ink supply roller 70. Ink is applied to the printing plate 30 as it passes through.

ここで、位置可変式テンションローラ12,14を、軸直角な方向にスライドして、軸位置を調整し、版支持体18の移動方向の前後位置を通過する版支持体18を押し出すことで、版支持体18の転写用ローラ13の外面通過時における、該版支持体18の曲率を所定の曲率に制御できる。例えば、位置可変式テンションローラを図2のa方向に動かすとタイミングベルト19a,19bがcの状態となって曲率が小さくなり、同図のb方向に動かすとタイミングベルト19a,19bがdの状態となって曲率が大きくなる。   Here, the position variable tension rollers 12 and 14 are slid in a direction perpendicular to the axis, the axis position is adjusted, and the plate support 18 passing through the front and rear positions in the moving direction of the plate support 18 is pushed out, When the plate support 18 passes through the outer surface of the transfer roller 13, the curvature of the plate support 18 can be controlled to a predetermined curvature. For example, when the position-variable tension roller is moved in the direction a in FIG. 2, the timing belts 19a and 19b are in the state c, and the curvature is reduced. When the position changeable tension roller is moved in the direction b in the figure, the timing belts 19a and 19b are in the state d. And the curvature increases.

この場合、転写用ローラ13の外面通過時における印刷版30の曲率を、印刷版30の種類に対応して記憶した記憶装置と、この種類に適応した曲率を該記憶装置から読み出し、曲率調整部材の押し出し量、即ち、本実施形態では位置可変式テンションローラ12,14の軸位置調整量を制御する制御部とを備えた構成とすることが好ましい。これにより、印刷版30の種類を、上記した制御盤を操作して或いは任意の入力手段を用いて入力するだけで、所定の印刷機のシリンダに適応した曲率に容易に調整することができる。   In this case, a storage device that stores the curvature of the printing plate 30 when it passes through the outer surface of the transfer roller 13 according to the type of the printing plate 30, and reads the curvature adapted to this type from the storage device, and adjusts the curvature of the storage device. It is preferable to include a control unit that controls the amount of extrusion, that is, the axial position adjustment amount of the position variable tension rollers 12 and 14 in this embodiment. As a result, the type of printing plate 30 can be easily adjusted to a curvature suitable for a cylinder of a predetermined printing press only by operating the above-mentioned control panel or using an arbitrary input means.

また、転写時における印刷版30と印刷用紙40の位置合わせを行うべく、印刷版30の版支持体18に対する取り付け位置及び印刷用紙40の紙支持体25に対する取り付け位置の目印となる位置合わせ手段を備えるのが好ましい。この場合、位置合わせ手段として、印刷版の種類に応じて、印刷版及び印刷用紙の種々異なる取り付け位置の目印をそれぞれ表示可能なLEDなどのランプを用いることができる。また、光センサや位置センサなど各種のセンサを用いて印刷版や印刷用紙の端部位置を検出するような構成とすることもできる。また、多色印刷の場合は、印刷色の異なる複数の印刷版30を順次交換し、これに合わせて使用するインキ供給手段も選択切り換えして用い、上述したような動作を繰り返し行って、多色の重ね刷りを行い、校正印刷物を得る。そして、得られた校正印刷物を目視検査して印刷版30の検版を行う。   Further, in order to align the printing plate 30 and the printing paper 40 at the time of transfer, alignment means serving as marks for the attachment position of the printing plate 30 to the plate support 18 and the attachment position of the printing paper 40 to the paper support 25 are provided. It is preferable to provide. In this case, a lamp such as an LED that can display marks at various attachment positions of the printing plate and the printing paper according to the type of the printing plate can be used as the alignment means. Moreover, it can also be set as the structure which detects the edge part position of a printing plate or a printing paper using various sensors, such as an optical sensor and a position sensor. In the case of multicolor printing, a plurality of printing plates 30 having different printing colors are sequentially exchanged, and the ink supply means to be used is switched accordingly. Overprint the colors to get a proof print. Then, the obtained calibration printed matter is visually inspected to inspect the printing plate 30.

かかる校正印刷装置1は、版支持ユニット11における版支持体18と紙支持ユニット20における紙支持体25とを移動させることにより、印刷版30と印刷用紙40を周方向に移動させながら、印刷版30の版支持ユニット11における転写用ローラ13の外面通過時に、版支持体18と共に所定の曲率となった印刷版30の版画を印刷用紙40に転写することができ、版支持体18の表面に印刷版30を支持する構成であるため、大きさの異なる複数種類の印刷版30に対処でき、種類の異なる印刷版30について校正印刷することができる。しかも、本校正印刷装置1は安価に製作できるため、コスト的に有利であるばかりか、従来のようなシリンダが不要であると共に、フラットな作業台を用いる必要がなく、占有面積を小さくすることができ、設置スペースの低減を図ることができる。   The proof printing apparatus 1 moves the printing plate 30 and the printing paper 40 in the circumferential direction by moving the plate support 18 in the plate support unit 11 and the paper support 25 in the paper support unit 20. When the plate support unit 11 of 30 passes through the outer surface of the transfer roller 13, the plate print of the printing plate 30 having a predetermined curvature can be transferred to the printing paper 40 together with the plate support 18, and is transferred to the surface of the plate support 18. Since the printing plate 30 is configured to be supported, a plurality of types of printing plates 30 having different sizes can be dealt with, and proof printing can be performed for the printing plates 30 having different types. In addition, since the proof printing apparatus 1 can be manufactured at low cost, it is advantageous in terms of cost, and it is not necessary to use a conventional cylinder, and the occupation area can be reduced. Therefore, the installation space can be reduced.

また、版支持体18の表面に印刷版30を支持し、紙支持体25の表面に印刷用紙40を支持すれば良いだけであるから、印刷版30や印刷用紙40が大きくても問題なく取扱うことができ、取扱作業の人数の低減を図れる。さらに、所定の曲率となった印刷版30の版画を印刷用紙40に転写することができるため、校正印刷物は、実際の印刷物の原寸法に極めて近い正確な状態で得られ、検版精度の向上を図ることができる。特に、軸位置を調整可能に設けられた位置可変式テンションローラ12,14等の曲率調整部材を設ければ、印刷版30の転写用ローラ13の外面通過時における曲率を調整することができ、より正確な校正印刷物が得られる。   Further, since it is only necessary to support the printing plate 30 on the surface of the plate support 18 and to support the printing paper 40 on the surface of the paper support 25, even if the printing plate 30 and the printing paper 40 are large, they can be handled without problems. This can reduce the number of people handling work. Furthermore, since the print of the printing plate 30 having a predetermined curvature can be transferred to the printing paper 40, the proof printed matter can be obtained in an accurate state very close to the original size of the actual printed matter, and the plate inspection accuracy can be improved. Can be achieved. In particular, if a curvature adjusting member such as a position variable tension roller 12, 14 provided so that the shaft position can be adjusted is provided, the curvature of the printing plate 30 when passing through the outer surface of the transfer roller 13 can be adjusted. A more accurate proof print can be obtained.

また、本実施形態においては、印刷版30の曲率を、印刷版30の種類に対応して記憶装置に記憶しておき、印刷版30の種類を入力することにより、印刷版30の種類に適応した曲率となるように、位置可変式テンションローラ12,14の軸位置調整量を制御するようにしているため、印刷版30の種類が変化しても、印刷版30の種類を入力すれば、この種類に適応した最適な曲率となるように、自動的に位置可変式テンションローラ12,14の軸位置調整量を制御でき、熟練を要することなく、容易に最適な曲率を得られる。   Further, in the present embodiment, the curvature of the printing plate 30 is stored in a storage device corresponding to the type of the printing plate 30 and is adapted to the type of the printing plate 30 by inputting the type of the printing plate 30. Therefore, even if the type of the printing plate 30 changes, if the type of the printing plate 30 is input, the amount of adjustment of the axial position of the position variable tension rollers 12 and 14 is controlled. The shaft position adjustment amount of the position-variable tension rollers 12 and 14 can be automatically controlled so as to obtain the optimum curvature adapted to this type, and the optimum curvature can be easily obtained without requiring skill.

なお、上記の実施形態では、タイミングベルト19a,19b、26a,26bの移動によって、版支持体18及び紙支持体25を介して印刷版30及び印刷用紙40が回転移動されるように構成したが、図3に示すように、版支持ユニット11のローラ12〜17及び紙支持ユニット20のローラ21〜24にそれぞれ巻き掛けた幅広のベルト部材50,60で版支持体及び紙支持体自体を兼ねるようにし、ベルト部材50,60の移動によって、該ベルト部材50,60の表面に直接装着した印刷版30及び印刷用紙40が回転移動されるように構成しても良い。   In the above embodiment, the printing plate 30 and the printing paper 40 are rotationally moved through the plate support 18 and the paper support 25 by the movement of the timing belts 19a, 19b, 26a, and 26b. As shown in FIG. 3, wide belt members 50 and 60 wound around the rollers 12 to 17 of the plate support unit 11 and the rollers 21 to 24 of the paper support unit 20 respectively serve as the plate support and the paper support itself. In this way, the printing plate 30 and the printing paper 40 mounted directly on the surface of the belt members 50 and 60 may be rotated and moved by the movement of the belt members 50 and 60.

また、版支持ユニット11のローラ12〜17及び紙支持ユニット20のローラ21〜24をいずれも、側面から見て多角形状となるような位置関係で配置しているが、転写用ローラとなるローラ13、位置可変式テンションローラ12,14及び被転写用ローラとなるローラ23を備えている限り、その使用本数等は限定されるものではない。また、版支持体18及び紙支持体25を、転写用ローラとなるローラ13と被転写用ローラとなるローラ23との間に送り込むことができれば、他のローラの配置は限定されるものではない。但し、上記のように側面から見て多角形状(より円に近い配置も含む)等とすれば、版支持体18及び紙支持体25が周方向に移動することになるため、占有面積の省スペース化に資する。   Further, the rollers 12 to 17 of the plate support unit 11 and the rollers 21 to 24 of the paper support unit 20 are all arranged in a positional relationship so as to have a polygonal shape when viewed from the side. 13. As long as the position-variable tension rollers 12, 14 and the roller 23 to be transferred are provided, the number of the rollers used is not limited. The arrangement of the other rollers is not limited as long as the plate support 18 and the paper support 25 can be fed between the roller 13 serving as a transfer roller and the roller 23 serving as a transfer target roller. . However, since the plate support 18 and the paper support 25 move in the circumferential direction if the polygonal shape (including arrangement closer to a circle) is used as seen from the side as described above, the occupied area can be saved. Contributes to space.

また、上記実施形態においては、紙支持ユニット20として、複数のローラを備え、タイミングベルト又は幅広のベルト部材を駆動させて、紙支持体25を周方向に移動させている。しかしながら、本発明においては、版支持体18に支持される印刷版30を、転写時に所定の曲率で支持できればよく、紙支持ユニット20としては、例えば、段ボール紙等の印刷用紙を平らな状態で直線的に供給し、転写時に印刷版30に接触させることができる機構であってもよい。但し、上記実施形態のように、印刷用紙も周方向に移動する構成とすれば、装置全体の占有面積を小さくでき、省スペース化の点で好ましい。   In the above embodiment, the paper support unit 20 includes a plurality of rollers, and drives the timing belt or the wide belt member to move the paper support 25 in the circumferential direction. However, in the present invention, it is sufficient that the printing plate 30 supported by the plate support 18 can be supported with a predetermined curvature at the time of transfer. As the paper support unit 20, for example, a printing paper such as a cardboard paper is flat. It may be a mechanism that can be supplied linearly and brought into contact with the printing plate 30 during transfer. However, if the printing paper is also configured to move in the circumferential direction as in the above embodiment, the occupied area of the entire apparatus can be reduced, which is preferable in terms of space saving.

さらに、上記実施形態においては、版支持ユニット11を下部に配置し、紙支持ユニット20を上部に配置しているが、例えば、逆に配置しても良く、それぞれその位置関係は限定されるものではない。また、版支持ユニット11に設けた版支持体の表面に沿って移動し、任意のマーキング部材により、版支持ユニット11の所定位置に印刷版をセットする位置をマーキングして指示できる位置合わせ手段としての走査装置を搭載することもできる。マーキング部材としては、ペンなどによって版支持体に直接マークを付ける部材を用いることもできるし、ピアノ線などの線部材を付設し、この線部材の位置により印刷版をセットする位置の目印とすることもできる。かかる走査装置を設けた場合には、例えば、コンピュータを用いて、印刷版をセットする位置を正確に指示することができる。   Furthermore, in the above-described embodiment, the plate support unit 11 is disposed at the lower part, and the paper support unit 20 is disposed at the upper part. is not. Also, as an alignment means that moves along the surface of the plate support provided in the plate support unit 11 and can mark and indicate the position where the printing plate is set at a predetermined position of the plate support unit 11 by an arbitrary marking member It is also possible to mount the scanning device. As the marking member, a member for directly marking the plate support with a pen or the like can be used, or a line member such as a piano wire is provided, and the position of the printing plate is set according to the position of the line member. You can also When such a scanning device is provided, for example, the position where the printing plate is set can be accurately designated using a computer.
