Definitions

the invention relates to a method for starting a Offset rotary printing press.
the inking units of the printing units have a metering device on which passage openings for the printing ink can be adjusted in zones, ie distributed over the width of the inking unit or the printing form. It is known to adjust these openings in accordance with the subject of the printing plate, that is, in accordance with the consumption of the individual ink zones. With this setting, an ink run-in is carried out when the inking rollers are switched off. A color profile set in this way is shown hatched in FIG.
the inking rollers are also placed on the printing plate, on which an ink layer or an ink density s is built up at the printing points.
the structure of the color density is shown in FIG. 2 with the dashed curve as a function of the number of prints or copies made.
the desired layer thickness or color density s F for continuous printing only occurs in zones with a low area coverage after approx. 1500 copies, which are to be regarded as waste.
zones with low ink consumption for example zone 1
register and register marks are only visible after a long period of time.
the initial abundant supply of printing ink in an ink zone with a high ink consumption, for example in ink zone 3 leads to an over-dyeing of the printing surfaces.
EP 0 529 257 B1 provides after an interruption in the printing process, such as. B. at the new beginning after washing the blanket, on the Color metering device an inverse color profile. It comes in handy with one Color zone with low color consumption exaggerated color and at one Ink zone with high ink consumption underestimated little ink to the inking unit fed.
the inking rollers are set to add to the subject to let the printing form react.
the offset rotary printing press has printing units, each with an inking and dampening unit, which dampen and ink the printing form on the plate cylinder.
Each inking unit contains a color metering device for setting a color profile zone by zone.
the speed of the printing press is given on the ordinate and the number of copies on the abscissa.
the start-up of the rotary printing press begins with the so-called loading of the production, with data stored for the machine setting being retrieved from a memory, for example settings of the folder or of the strand register.
the printing press is then driven at a first speed n1 of the plate cylinder. This is advantageous the pulling speed of about 600 h -1 .
the web to be printed has already been drawn into the printing press.
the dryer for the paper web is now activated, ie its preheating is started.
the metering devices of the inking units of the printing units of the offset rotary printing press are also set to an inverse color profile.
the metering device is, for example, zone screws for ink zones into which the inking unit is divided over its width, as was already explained at the beginning in the prior art. With the zone screws, the height f of a passage gap for the printing ink between an ink knife and an ink duct can be set for each ink zone.
the settings of all heights f of the color zones provide a color profile, as hatched in FIG. 1.
the color profile P F for continuous printing is used. This is obtained, for example, by scanning the printing plate.
the area coverage of the pressure of each zone is determined and the percentage opening f of the passage gap of each color zone is determined therefrom.
the difference from 100% transmission provides the value of the inverse color profile P i of the respective color zone, as entered in FIG. 1.
P i the value of the inverse color profile
the inverse color profile a defined amount of color is now fed to the cleaned inking unit, it is pre-inked.
the color profile on the ductor has reached the area of the film roller, the latter is placed against the ductor and during a certain number of plate cylinder revolutions, for example two revolutions, and at a special ductor speed (e.g. 2 to 3 min -1 ) of ink transported to the inking unit.
the ink and dampening rollers are switched off from the plate cylinder.
the film roller is then turned off again by the doctor and the color profile P F is set on the ink metering device for continuous printing.
the printing press is run to a second speed n2 of approximately 5000 h -1 and remains at this speed until the dryer is released. It is the ready display of the dryer for production, for which z. B. Flaps of the dryer are to be closed.
the dryer is already released during the method steps carried out at the first speed n1, so that the printing press is immediately accelerated to a third speed n3 of approximately 16000 h -1 without remaining at the second speed n2.
the rubber blankets are pre-moistened. This is done at short intervals using the blanket washer.
the rubber blankets are already in a clean condition. The dampening prevents the web from sticking when the print is turned on later.
the color register and the cutting register are switched on (armed).
the waste switch is set to the "good” position and the counting of the copies begins (net counter on).
the printing press is then run up to a fourth speed n4 for continuous printing, for example 70000 h -1 . This start-up takes place relatively slowly, for example over a period of 180 seconds, as a result of which the printed copies are sellable production and are therefore not waste.
the waste switch is set to the "bad" position and the number of copies is ended (net counter off).
the run-out sequence is processed. This includes turning off the pressure, turning off the metering device (film roller off), turning off the inking rollers and turning off the dampening rollers.
the printing press is then brought down to a fifth speed n5 of approximately 20,000 h -1 .
n5 a fifth speed of approximately 20,000 h -1 .
the inking unit is washed and brought into the required "empty" state for the described starting of the printing press for a new production.
the rubber blankets are washed at speed n5.
the press is then stopped.
the inking unit thanks to the pre-inking described, already provides the required color density S F for waste-free printing after approximately 100 copies (see FIG. 2).
