Abstract
Description
Die Erfindung betrifft einen Leitstand einer Druckmaschine nach dem Oberbegriff des Anspruchs 1.The invention relates to a control station of a printing press according to the preamble of claim 1.
Als farbliche Referenz bei der Ausführung eines Druckauftrags auf einer Druckmaschine, wie z. B. auf einer Rollenrotationsdruckmaschine oder auf einer Bogendruckmaschine, dient nach der Praxis üblicherweise ein auf einem Farbtintenstrahldrucker angefertigtes Referenzmuster, wobei ein Drucker die auf der Druckmaschine gedruckten Druckexemplare mit diesem Referenzmuster an einem Leitstand der Druckmaschine vergleicht. Solche auf einem Farbtintenstrahldrucker geduckten Referenzmuster bezeichnet man auch als Hardcopy-Proof. Um einen von einer Raumbeleuchtung unabhängigen, visuellen Vergleich zwischen den gedruckten Druckexemplaren und dem als farbliche Referenz dienenden Hardcopy-Proof zu ermöglichen, ist dem Leitstand der Druckmaschine mindestens eine Normlichtquelle zugeordnet, mit Hilfe derer der Leitstand zumindest partiell ausgeleuchtet werden kann.As a color reference in the execution of a print job on a press, such. B. on a web-fed rotary printing press or on a sheet-fed press, in practice usually serves a made on a color inkjet printer reference pattern, wherein a printer compares printed on the printing copies with this reference pattern at a control station of the printing press. Such on a color inkjet printer crouched reference pattern is also called a hard copy proof. In order to enable a visual comparison, independent of a room lighting, between the printed copies and the hardcopy proof serving as a color reference, the control station of the printing press is assigned at least one standard light source with which the control center can be at least partially illuminated.
Weiterhin ist es aus der Praxis bereits bekannt, zusätzlich zu dem oder als Ersatz für das auf dem Farbtintenstrahldrucker angefertigte Hardcopy-Proof eine farbliche Referenz auf einem farbverbindlichen Monitor zu visualisieren. Die Visualisierung einer farblichen Referenz auf einem farbverbindlichen Monitor wird auch als Softproof bezeichnet. Der zuverlässige visuelle Vergleich zwischen den Druckexemplaren und einem als farbliche Referenz dienenden Softproof bereitet jedoch an aus der Praxis bekannten Druckmaschinenleitständen Schwierigkeiten, da die Helligkeit und/oder der Kontrast von farbverbindlichen Monitoren eingeschränkt ist.Furthermore, it is already known from practice to visualize a color reference on a color-consistent monitor in addition to or as a replacement for the hardcopy proof produced on the color inkjet printer. The visualization of a color reference on a color-consistent monitor is also referred to as soft proofing. However, the reliable visual comparison between the prints and a color proof soft proof is difficult for press operators known in the art because the brightness and / or contrast of color accurate monitors is limited.
Hiervon ausgehend liegt der vorliegenden Erfindung das Problem zugrunde einen neuartigen Leitstand einer Druckmaschine zu schaffen, bei welchem Softproofs mit gedruckten Druckexemplaren sicher visuell verglichen werden können.On this basis, the present invention is based on the problem to provide a novel control station of a printing press, in which soft proofs can be reliably visually compared with printed copies.
Dieses Problem wird durch einen Leitstand gemäß Anspruch 1 gelöst. Erfindungsgemäß ist eine von der oder jeder Normlichtquelle erzeugte Leuchtstärke veränderbar, um so die von der oder jeder Normlichtquelle erzeugte Leuchtstärke an eine mit dem oder jedem farbverbindlichen Monitor erzielbare Helligkeit und/oder einen mit dem oder jedem farbverbindlichen Monitor erzielbaren Kontrast in der Visualisierung des Softproofs anzupassen. Hierdurch können nun auch Softproofs mit gedruckten Druckexemplaren sicher visuell verglichen werden.This problem is solved by a control station according to claim 1. According to the invention, a luminous intensity generated by the or each standard light source can be changed so as to adapt the luminosity generated by the or each standard light source to a brightness achievable with the or each color-consistent monitor and / or a contrast achievable with the or each color-consistent monitor in the visualization of the softproof , As a result, soft proofs can now be visually compared with printed copies.
Nach einer vorteilhaften Weiterbildung der Erfindung umfasst der Leitstand mindestens eine zwischen der oder jeder Normlichtquelle und dem oder jedem farbverbindlichen Monitor angeordnete Abdeckung bzw. Blende, um einen Einfall von Normlicht auf den oder jeden farbverbindlichen Monitor einzustellen.According to an advantageous embodiment of the invention, the control center comprises at least one arranged between the or each standard light source and the or each farbverbindlichen monitor cover or aperture to set an incidence of standard light on the or each farbverbindlichen monitor.
Nach einer weiteren vorteilhaften Weiterbildung der Erfindung umfasst der Leitstand mindestens eine Einrichtung, um zumindest den oder jeden farbverbindlichen Monitor vor einem Einfall von Streulicht insbesondere der Raumbeleuchtung zu schützen, welche insbesondere elektromotorisch verstellbar ausgebildet sein kann.According to a further advantageous embodiment of the invention, the control center comprises at least one device to protect at least the or each color-consistent monitor from an incidence of stray light in particular the room lighting, which may be formed in particular adjustable by electric motor.
Vorzugsweise umfasst der Leitstand eine Steuerungs- bzw. Regelungseinrichtung, um die von der oder jeder Normlichtquelle erzeugte Leuchtstärke und/oder die Einstellung der oder jeder Abdeckung bzw. Blende zur Beeinflussung des Normlichteinfalls auf den oder jeden farbverbindlichen Monitor und/oder die Einstellung der oder jeder Einrichtung zur Beeinflussung des Streulichteinfalls in den Leitstand zu speichern sowie zu steuern bzw. zu regeln, wobei insbesondere vordefinierte Einstellungen abrufbar sein können.Preferably, the control station comprises a control means for controlling the luminous intensity produced by the or each standard light source and / or adjusting the or each aperture for influencing the incident normal light incident on the or each color accurate monitor and / or adjusting the or each Device for influencing the scattered light incidence in the control room to store as well as to control or regulate, in particular predefined settings can be retrieved.

Hierdurch kann gewährleistet werden, dass an einem Leitstand ein gedrucktes Druckexemplar sicher mit einem auf einem farbverbindlichen Monitor visualisierten Softproof abgeglichen bzw. verglichen werden kann.In this way, it can be ensured that a printed copy can be reliably matched or compared with a softproof visualized on a color-binding monitor at a control station.
Im bevorzugten Ausführungsbeispiel ist die Normlichtquelle 13 in ihrer Leuchtstärke bzw. Leuchtintensität unmittelbar veränderbar, wobei hierzu der Normlichtquelle 13 gemäß
Alternativ ist es auch möglich, mehrere Normlichtquellen an einem Leitstand zu verwenden, die in ihrer Leuchtstärke bzw. Leuchtintensität nicht verändert werden können, wobei jedoch die von den Normlichtquellen erzeugte Leuchtstärke bzw. Leuchtintensität dadurch verändert werden kann, dass die Anzahl der eingeschalteten Normlichtquellen verändert wird.Alternatively, it is also possible to use a plurality of standard light sources on a control station, which can not be changed in their luminous intensity or luminous intensity, but the luminosity or luminous intensity produced by the standard light sources can be changed by changing the number of standard illuminants switched on ,
Weiterhin ist es zur Veränderung der von der oder jeder Normlichtquelle erzeugten Leuchtstärke bzw. Leuchtintensität möglich, der oder jeder Normlichtquelle 13 mindestens eine Einrichtung zuzuordnen, die von der jeweiligen Normlichtquelle emittiertes Normlicht zumindest teilweise absorbiert. Dadurch, dass mindestens einer Normlichtquelle mindestens eine solche Einrichtung selektiv vorgeschaltet wird, kann die von der oder jeder Normlichtquelle erzeugte Leuchtstärke bzw. Leuchtintensität angepasst werden.Furthermore, to change the luminous intensity or luminous intensity produced by the or each standard light source, it is possible to assign to the or each

Hierdurch ist es möglich, die Leuchtintensität bzw. Leuchtstärke des Normlichts im unmittelbaren Einflussbereich des farbverbindlichen Monitors 12 exakt einzustellen. Die Blende 15 kann hierzu translatorisch und/oder rotatorisch relativ zum farbverbindlichen Monitor 12 verstellt werden.This makes it possible to set the luminous intensity or luminosity of the standard light in the immediate sphere of influence of the color-
Der erfindungsgemäße Leitstand verfügt weiterhin über eine Einrichtung, um zumindest den oder jeden farbverbindlichen Monitor 12 vor einem Einfall von Streulicht der Raumbeleuchtung zu schützen. Im gezeigten Ausführungsbeispiel ist diese Einrichtung als an einer Laufschiene 16 geführter, elektromotorisch verfahrbarer Vorhang 17 ausgebildet, der den gesamten Leitstand vor Einfall von Streulicht von unterschiedlichen Richtungen her schützt. So schützt der in
Besonders bevorzugt ist ein Leitstand, der eine Steuerungs- und Regelungseinrichtung umfasst, um die von der Normlichtquelle 13 erzeugte Leuchtstärke bzw. Leuchtintensität und die Einstellung der Blende 15 zur Beeinflussung des Normlichteinfalls auf den farbverbindlichen Monitor 12 sowie die Einstellung des Vorhangs 17 zur Beeinflussung des Streulichteinfalls in den Leitstand zu speichern sowie hiervon abhängig zu steuern bzw. zu regeln. Hierdurch wird es z. B. möglich, einen erfindungsgemäßen Leitstand auf Knopfdruck in einen sogenannten Abmusterungsmodus zu schalten, um so z. B. die Leuchtintensität bzw. Leuchtstärke der Normlichtquelle 13 sowie die Position des Vorhangs 17 auf definierte Zielgrößen einzustellen, um so automatisch für einen visuellen Vergleich von gedruckten Druckexemplaren mit dem Softproof optimale Bedingungen am Leitstand zu gewährleisten.Particularly preferred is a control station, which includes a control and regulating device to the luminosity or luminous intensity generated by the
