Definitions

  • the respective printing plate is wetted with an aqueous liquid by a so-called dampening system in order to ensure that in a subsequent process step the image areas take on the color, while the image-free areas behave ink-repellently.
  • the aqueous liquid often consists of a mixture with alcohol, usually isopropanol, and a chemical mixture of up to around twenty substances, which is referred to below as an additive.
  • the additive is available in concentrations of 1 to 8% vol., the alcohol from 0.5 to 20% vol. added.
  • the concentration of the water is between 72% and 98.5% - vol.
  • alcohol is sometimes completely avoided. In this case, the additive is also called an alcohol substitute.
  • the optimized additive then fully or at least partially takes over the function of isopropanol.
  • a major problem with offset printing is the insufficient availability of the process, which is typically only around 80% and is therefore characterized by long downtimes of very investment-intensive printing machines. For example, with a so-called 64-page offset rotary printing line, you would save around EUR 35,000 per year if the actual production time per day could be extended by an average of just two minutes. New, intensive practical studies have clearly shown that the low availability of offset printing machines is largely due to an undefined, unknown physical and chemical composition of the process fluid that has not yet been measurable in the process and therefore, in particular, cannot be controlled.
  • the concentrations of alcohol in the dampening solution are currently between 6% and 20% and make it easier to use so-called film dampening systems in the case of web and sheetfed offset.
  • the latter consist of several rollers coated with rubber mixtures and/or metals, which rotate in contact with one another with a certain contact pressure and transport the dampening solution to the printing plate in the form of a film of adjustable layer thickness. This transport process is promoted by the addition of isopropanol as a result of the resulting reduction in the surface tension of the liquid film.
  • contactless systems in particular spray dampening systems operated with nozzles or dampening systems which have rollers with plush covers, are also used.
  • the new method according to the invention is also in accordance with the prior art in these versions of utmost importance as it enables an optimal composition of the chemicals in the fountain solution.
  • a real alternative to alcohol are the so-called surfactants, which have comparable advantages in terms of the wetting properties of the dampening solution on the rollers of the dampening unit.
  • surfactants are not VOC's.
  • surfactants lead to undesirable foaming and to quality-reducing emulsification of ink and fountain solution, so that in many practical cases alcohol-free printing fails and has to be replaced by printing with alcohol.
  • the aim of the present invention is therefore to readjust the composition of the dampening solution to the respective target values by continuously measuring and regulating the composition of the dampening solution, ie by continuously re-dosing the individual differently impoverishing chemical components or selected groups of components, in order to ensure the availability of the offset printing process to the values of the competing Gravure pressure, ie to around 90 to 95%.
  • JP-A-4327940 It is intended to control the concentrations of individual components in the fountain solution of offset printing machines by measuring the pH value, the conductivity, the refractive index, the specific gravity and the gas concentration and to replenish the respective component via pumps over a specific period of time if the concentration value is high is not within a range between an upper and a lower limit.
  • a method and a device are used for the first time in printing technology, which continuously measure the concentrations of the individual components of the additive and regulate them to predetermined optimal values due to selective weakening of electromagnetic radiation. This prevents the process liquid from suffering a depletion or an overdose of individual components of the additive, so that the printing process can be continued continuously at the optimal operating point with high stability and availability.
  • the process not only works with alcohol-free printing, ie for substitute materials, but that the selectivity of the measurement and control of the additive can also be maintained when printing with additional admixture of alcohol, ie that the alcohol does not cause any distortion of the measurement of the concentrations of the individual components of the additive.
  • the selective measurement of the concentrations of the individual components or groups of different chemical compounds is coupled with a dosing system that removes the various components from different containers via a system consisting of clocked valves and pumps and supplies them to the dampening solution in a controlled manner.
  • This new process significantly optimizes offset printing with alcohol. For the first time, printing without alcohol is put on a basis that enables a long-term process while meeting the economic constraints.
  • the too narrow window of variation in the concentrations of the individual chemical components of ready-to-use additives is expanded as desired by the new process, so that constant changes of the dampening solution, in particular Due to the already mentioned search for better dampening solution additives when the printing process is shut down for several hours and the corresponding negative consequences for the disposal of the previously used dampening solution and thus also for the economic efficiency of the printing process, the new process no longer applies.
  • dosing devices are used to produce the process liquid, which volumetrically mix the two or three components under fixed conditions within the framework of a control and into the liquid circuit of the printing press according to the respective consumption, ie according to the removal of the liquid through the paper to be printed.
  • systems with conventional dosing pumps are currently in use.
  • a major disadvantage of these systems is that neither the mixing devices malfunction nor changes in the physical and/or chemical composition, e.g. as a result of chemical reactions or absorption or desorption processes through the printing ink, the paper, through the pipeline or the machine modules, can be detected.
  • evaporation processes in these classic dosing methods lead to significant concentration errors.
  • the sensors currently in use as the only control instruments for detecting electrical conductivity are not suitable for quantitative measurement of the concentration of the respective additive or substitute because of the heavy and fluctuating contamination of the process liquid.
  • the important chemical key components of the additives, which enable the printing process cannot be detected by a conductivity measurement because these substances cannot be dissociated in water.
  • the pH probe which has already been introduced more or less as a standard in offset printing, can only be used as an indicator shortly before the functioning of the printing process collapses, since the required strong chemical buffering of the process liquid, for example by citric acid, also causes a change in the pH value major changes in the chemical composition are prevented.
  • the aims of the present invention are therefore a method and a device for implementing the method, which enables quantitative, continuous measurement and control of the concentrations of the individual components of the respective additive or substitute in a matrix of up to 20 chemical components without incorrect influence from other substances , such as alcohol, dirt, paint and paper particles, gas bubbles, salts from the paper coating and other contaminants typical of offset printing.
  • the individual components must be measured and controlled with a material-dependent accuracy of between 10 ppm and 3.0%. This problem has not yet been solved in any practical case.
  • the present invention solves the tasks set, among other things, in that the individual chemical components are continuously measured and regulated to the dampening solution circuit as pure raw materials and / or as partial mixtures of several components, usually in mixtures with water, so that they are simply in the dampening solution solve and in particular do not form separate phases. In this way, chemical formulations in particular can be realized that separate in a prefabricated additive concentrate and would therefore not lead to a homogeneous solution.
  • the weakening of electromagnetic radiation as it passes through the dampening solution is used to determine the concentration.
  • Process liquid (2) located in a tank (1) is circulated by circulation pumps (3) to the printing press (4) and back to the tank (1) via pipes (5).
  • the respective concentrations of the individual chemical components of the additive are continuously measured by a measuring system (6).
  • the specified chemical components K1, K2, K3,... to Kn are fed into the process liquid (2) via pumps (7) and valves (8).
  • the different required target concentrations of the chemical components K1 to Kn are guaranteed by the fact that the measuring system (6) continuously measures the actual concentrations and, as part of a control system, replenishes the amount of the respective component so that the actual value is equal to the specified one Target value is.
  • the concentration of alcohol, unless alcohol-free printing is used is continuously measured in the process liquid (2) and the Alcohol lost essentially through evaporation is fed in from a storage container (13) via a unit consisting of a valve and metering pump (14), so that even when printing with alcohol, the target and actual values constantly match and the availability and quality of the printing process is guaranteed are.
  • An agitator (15) is used to homogenize the process liquid.
  • Fig 2 outlines an arrangement consisting of a printing press (16), a dampening solution tank (17), a dampening solution (18) with circulation (19) and the chemical components K1 to Kn (20), which have a Venturi nozzle (21) and a pump ( 22) is operated, the chemical components K1 to Kn are sucked in via valves (23) and fed into the dampening solution (18), the concentrations of the chemical components being measured via the measuring and control system (24) takes place.
  • the make-up (25) of water with automatic level control and the agitator (26) correspond to the arrangements of Fig. 1 .
  • Fig. 3 is in the overall arrangement consisting of printing press (27), dampening solution tank (28), dampening solution (29), measuring and control system (30), agitator (31), water feed (32) with fill level control (33) and dampening solution circulation (34), as Additional component a static mixer (35) is realized.
  • the dampening water (29) circulated via the pump (36) is mixed with the chemical components K1 to Kn (37), which are fed into the circuit (39) via the valves (38), in the static mixer (35), as follows that both the measuring system (30) and the circuit (34) have homogeneous liquid mixtures with the aim that the entire system in Fig. 3 works optimally.
  • Fig. 4 represents a version of the invention, which is characterized by a premixing of the chemical components K1 to Kn (42) via pumps (50a) with a water supply (41) in a mixing container (40).
  • This arrangement ensures that the control process of the measuring system (43) for achieving the target concentrations of the chemical components K1 to Kn (42) is significantly shortened, so that the composition of the dampening solution (44) in the dampening solution tank (45) also over shorter time intervals always has the specified target values.
  • a homogenization device (39) is also used in the premixing container (40).
  • the latter can also be according to Fig. 3 be a static mixer.
  • Fig. 5 shows a simple variant according to the invention, in which the chemical components K1 to Kn (51) are metered in via a valve (54) via calibrated metering pumps (53) controlled by the measuring system (52) in accordance with the respective target value of the individual component.
  • the level measurement (55) and the agitator (56), in combination with the water supply (57), enable a homogeneous mixture of the dampening water (58), which circulates via the circulation pump (59) in the circuit (60) between the printing press (61) and the dampening water cooling device (62).
