Description

The The present invention relates to a method for treating a Printing form according to the preamble of claim 1.

Farther The present invention relates to the use of a device according to the preamble of Claim 10.

Out the prior art it is already known, printing plates, in particular such for the offset printing, such that they not only for a single printing process, but also for several, different print images generating printing processes, used and therefore as reusable or reproducible Printing forms can be called.

Such a reusable printing form is already on the EP 1 375 136 A1 known, wherein the printing form a carrier, for. As titanium, with a printing surface and an occupancy of the surface with an amphiphilic substance, eg. As a hydroxamic acid or a phosphonic acid having. The amphiphilic coating is removed pixel by pixel by infrared irradiation, so that a printed image in the form of hydrophilic sites of the carrier surface and hydrophobic, occupied by the amphiphilic substance places. The printing form is further erasable by a large-area ultraviolet irradiation.

On the EP 0 747 217 B1 already a method and an apparatus for cleaning a cylinder, for example a forme cylinder, a rotary printing machine is known, wherein a cleaning device comprises a nozzle or a series of nozzles for - for example, compressed air - applying powdered blasting agent and a fluid supply for water. The powdery blasting medium transported onto the surface of the cylinder tears off paint / lacquer / dirt particles therefrom. By means of a suction, the particles removed from the surface of the cylinder are removed. An assignment of the printing form with a selected substance or its removal is in the EP 0 747 217 B1 but not described.

Furthermore, from the DE 42 16 636 A1 a method and an apparatus for erasing the ink-carrying layer of a printing plate formed by a thermal transfer method known, wherein a quenching device is provided which ejects a jet of water directed obliquely and under high pressure on the surface of the printing plate. However, the use of a pulverulent blasting agent in the water jet is not described. The device is preferably encapsulated and has a disposal for the water and the removed coating. A new coating of the printing form is carried out separately in the thermal transfer process, ie with a time delay and by means of a separate device.

Out US 2004/0202787 A1 is a method and an apparatus for the Apply and remove imageable material on the surface of a Printing form known, with a nozzle is used, which optionally the liquid, imageable material or a cleaning fluid ejects. The Removal can be effected by a vacuum suction. The usage a powdery one Blasting agent is not described.

The documents DE 102 1772 A1 and JP 2002 059527 A further teach to provide a printing form only in places with an imageable substance, which should be actually imaged. In the DE 102 17 172 A1 These places are additionally provided with a border area, while in the JP 2002 059527 A a correction possibility of damaged areas is provided.

Out the remote field of dental cleaning are cleaning devices known that both an inner hard material jet and an outer, concentric liquid jet use. The hard material jet is used for abrasive cleaning, while the liquid jet binds the hard material after striking the tooth to be cleaned and facilitates a suction. Exemplary here are the products of Electromedical Systems (EMS), Munich, called, such. For example, the device "AIR-FLOW" and the consumables "EMS Abrasive Powder "(see also http://www.ems-dent.com/en/air_abrasion.htm).

When using reusable printing plates, the process steps of re-imaging (cleaning, ablation, initialization, coating / coating, rinsing, imaging, developing, rinsing, drying) usually follow one another serially, so that their process times add up. Done again Imaging in a printing press, it may have to stand still until completion of the Wiederbebilderungsvorgangs. A significant loss of production can be the result. Furthermore, separate devices for carrying out the individual method steps are usually used. There is therefore a desire for time-limited re-imaging methods.

The Application of aggressive chemicals for surface cleaning and / or extinguishing Image information in the course of a re-imaging process leads to the Printing machine to foreseeable problems, which is why a desire For alternative, less aggressive on components of the printing press effective cleaning and / or extinguishing procedures consists.

Exact or even exact-pixel extinguishing devices, such as. B. Laser heads, and Coating devices, such. As inkjet heads, work resolution-related slow and therefore often uneconomical.

In 1 a sequence of an embodiment of the method according to the invention is shown. In one process step 100 (Provide) becomes a printing form 102 with a carrier 104 (or: a substrate), which is a printing surface 105 and an applied coating on the carrier 106 provided an amphiphilic substance. The printing form can be a wet or dry offset printing form (in the following, it is assumed without restriction that a wet offset printing plate is used).

The carrier 104 can be made of a metal surface, for. B. made of titanium, wherein the metal surface on its surface -. B. to titanium dioxide - can be oxidized. The carrier has a homogeneous hydrophobic or hydrophilic surface. In the following, it is assumed without limitation that the surface of the titanium oxide is oxidized, which is hydrophilic on its surface.

By covering the carrier 104 with an occupancy 106 the surface property is reversed in terms of wettability with water. The occupancy therefore includes an amphiphilic substance (or: amphiphilic molecules) which bind to the surface of the carrier and z. B. reverse a hydrophilic surface when fully occupied in a hydrophobic and preferably at the same time lipophilic surface.

Such surface coated with amphiphilic molecules can be as in process step 110 (Imaging), imagewise back to the hydrophilic state. For this purpose, z. B. using the infrared radiation 112 an infrared laser (example: wavelength about 810 to 1100 nm, power about 1 to 5 W, fluence about 30 to 40 J / cm 2 at a Bebilderungsgeschwindigkeit, ie a movement of the printing plate, from about 1 to 2 m / s) in pixels assignment 106 with amphiphilic molecules in such places 114 , which should not lead to color (non-image points), removed and the printing form 102 in this way - negative - illustrated or described. The non-illustrated places 116 , which are further occupied by amphiphilic molecules, remain lipophilic due to the occupancy and form the color-guiding image sites (image sites). This creates a printable subject.

In one process step 120 (Damp) becomes the printing form 102 with a dampening solution 122 provided the surface at the hydrophilic sites 114 but not at the sites occupied by the amphiphilic substance 116 wetted. In one process step 130 (Colorize) becomes the printing form 102 at the lipophilic sites 116 with printing ink 132 Mistake. After moistening and dyeing is a printing plate 102 for that in the process step 140 (Print) shown imprinting the image information on a substrate 142 , z. As paper, cardboard or foil in sheet or web form available.

The process steps 120 . 130 and 140 can be a repeat 144 go through, with a variety of printed products with the through the imaging 110 produced printed image.

After the end of printing or during a print interruption can in one step 150 (Treat) the printing form 102 with abrasion particles 152 ie with particles that serve abrasion and with a liquid 154 , preferably water or deionized water, treated, for example radiated. According to the invention, the liquid transports an amphiphilic substance 155 (or: amphiphilic molecules), preferably in the form of water-soluble, amphiphilic molecules, with which the surface is at least partially occupied.

By treating 150 the surface becomes at the same time of printing ink 132 cleaned and covered with the amphiphilic substance. In this way the printing form becomes 102 at least partially offset in a state which the initial state in the provision 100 essentially corresponds. The printing form can be both full-surface and locally in a selected area, eg. In a message or address field for personalized printing, in the initial state for re-imaging 110 be offset.

After the treatment 150 can the printing form 102 in the course of a repetition 156 the procedure steps 110 . 120 . 130 at least partially imaged and moistened again and dyed to then in a process step 140 to be reprinted.

The process step of treating 150 Thus, it preferably comprises time-parallel cleaning (at least of color), erasure of the image information, initialization of the (metal oxide) surface and reapplication with amphiphilic substance.

In 2 a sequence of a further embodiment of the method according to the invention is shown. In one process step 200 becomes a moistened, colored and already printed form 102 - Comparable to the printing plate in process step 140 in 1 - provided for a treatment. The treatment takes place in process step 210 , wherein the printing form 102 at least in a first section 212 with abrasion particles 152 and a liquid transporting an amphiphilic substance 154 , preferably water, is treated. The abrasion particles 152 can be transported by a gas, in particular by a gas stream ejected from a nozzle, and thus onto the surface of the printing plate 102 be moved, that with a suitable parameter selection of the abrasive particle treatment abrasion at least of printing ink 132 he follows. At the same time, the liquid 154 with the amphiphilic substance, e.g. As ejected from a nozzle jet, so on the surface of the printing plate 102 Directed moves that a preferably homogeneous occupancy 106 the surface at least in the section 212 with the amphiphilic substance. In the first part 212 is by treating 210 deleted a previously generated print image or previously generated image information. In a second section 214 can the printing form 102 remain untreated, ie in this section, the previously generated print image is retained.

The Parameter selection in Abrasionpartikel treatment concerns z. B. the material of the particles (see below), the particle size (eg. granulation in the range between about 60 and about 200 microns; see below), the Particle shape (eg spherical or irregularly shaped) and / or the speed of the transport medium (eg a gas, d. H. the pressure used; see below).

For example can Aluminum oxide particles (Al2O3, Mohs hardness 9) with a medium Diameter in the range of about 20 to about 30 microns, preferably about 27 microns, sodium carbonate particles (Na2CO3, Mohs hardness 7) with a mean diameter in the range of about 90 to about 110 Micrometer, preferably about 100 microns, or amino particles (Mohs hardness 3) with a mean diameter in the range of about 60 to about 70 microns, preferably about 63 microns, can be used. Other particle materials are silicic acid or silica in combination with sodium carbonate. The pressure of the gas, which transported the hard material is preferably in a range between about 3 and about 5 bar, preferably about 4 bar, selected.

The Method works preferably in the low pressure range below 10 bar. The pressure of the liquid, which transports the amphiphilic substance is preferably in a range between about 1 and about 3 bar, preferably about 1 bar, selected. The pressure of the gas transporting the hard material is preferred in a range between about 3 and about 5 bar, preferably about 4 bar, chosen.

The treatment can be done in rows or strips. For this purpose, a treatment device in the direction of movement 216 over the printing form 102 be guided.

In 3 a sequence of a further embodiment of the method according to the invention is shown, wherein method step 300 (Provision) the process step 200 in 2 equivalent. In one process step 310 (Treat) becomes the printing form 102 at least in a first section 212 with abrasion particles 152 and with a liquid transporting an amphiphilic substance 154 treated. The parameters of the abrasive particle treatment can be selected such that not only - as in 2 shown - printing ink 132 worn and the occupancy 106 is renewed, but that by the abrasion of material of the wearer 104 a defined roughness of the surface of the carrier 104 is set.

In a second section 214 the surface remains 102 in the state of deployment 300 , ie in this section there is no deletion and no adjustment of the roughness.

In 4 a sequence of a further embodiment of the method according to the invention is shown. In process step 400 (Provision) will - comparable to the process step 200 in 2 - a printing form 102 provided, wherein the printing form 102 at a defect site 402 in the occupancy of the amphiphilic substance has a defect in the form of a detachment of amphiphilic molecules, so that at these points no color, but dampening solution 404 to be led.

In one process step 410 (Treat) will correct the defect site 402 a first section 412 with a combination of z. B. gas-guided Abrasionspartikeln and liquid-guided amphiphilic substance treated so that a repurposing takes place with the amphiphilic substance. The section 412 can then in a process step 110 in 1 comparable process step be imaged again.

In process step 410 it is sufficient to choose the parameters of Abrasionspartikel treatment so that only printing ink 132 and possibly not tightly bound molecules of the amphiphilic substance 106 be removed to the surface of the printing form 102 to prepare for a new assignment.

In 5 is a schematic view of an embodiment of a device used in the invention 500 shown. The device 500 includes a first nozzle 502 and one concentric with the first nozzle 502 arranged second nozzle 504 , In other words: the first nozzle 502 is in the annular, second nozzle 504 integrated. The first nozzle 502 is about a first feed 506 with a gas stream 508 , preferably an air stream, supplies which abrasive particles 510 transported. The one with the abrasion particles 510 , z. B. provided using an injector gas stream 508 is through a first outlet 512 ejected in the way that the abrasive particles 510 to the surface of the printing form 102 get there and develop their abrasive effect.

The second nozzle 504 is via a second feed 514 with a liquid flow 516 , preferably a water stream, which supplies an amphiphilic substance 518 transported. The one with the amphiphilic substance 518 provided liquid flow 516 is through a second outlet 520 expelled in the way that the amphiphilic substance 518 to the surface of the printing form 102 arrives and this occupied.

The concentric emission of the gas stream 508 and the liquid flow 516 has the advantage that the liquid the ejected abrasive particles 510 (or the particle dust) binds after the abrasion and thus an uncontrolled spreading of Abrasionspartikel 510 , z. B. as dust in a process station of a Bebilderungseinheit prevented.

The device 500 can z. B. line by line over the printing plate 102 be moved as indicated by the arrow 522 indicated and the printing form 102 can z. B. are moved in a direction perpendicular thereto, for. B. by rotation of a printing plate 102 receiving cylinder, so that each point of the printing form of the device 500 can be treated.

A sweeping over the printing form 102 with the device 500 thus leads to a line by line removal of impurities, color, dampening solution, occupancy with amphiphilic substance and / or carrier material (depending on the choice of parameters of Abrasionspartikel treatment) in sections in which the device 500 is activated. In other words: by a local activation / deactivation of the device 500 during the relative movement of the device 500 to the printing form 102 will be treating the printing form 102 at selected points or in selected sections.

The first nozzle 502 encounters a gas stream loaded with abrasive particles 508 and the second nozzle 504 a liquid stream charged with the amphiphilic substance 516 out. The respective outlet 512 and 520 the two nozzles 502 respectively. 504 is provided or arranged in such a way that one of the abrasive gas stream 508 treated site of the printing form 102 in a relative movement between the device 600 and the printing form 102 then from the occupying liquid flow 516 is treated. In other words: the two exit points of the two streams are adjacent, in particular immediately adjacent to each other. The cleaning nozzle 502 is the occupancy nozzle 504 in the direction of movement 522 preferably arranged upstream.

In 7 is a schematic view of another embodiment of the device used in the invention 700 shown. The nozzle arrangement of the device 700 differs from the nozzle arrangement of the device 600 in 6 in that the respective outlet of the nozzles 502 and 504 provided in the way that the two streams 508 and 516 either in the same place of the printing form 102 or - as shown - on partially overlapping locations of the printing form 102 are directed.

In 8th is a schematic view of another embodiment of the device used in the invention 800 shown. The device 800 corresponds to the device 500 in 5 However, the nozzle assembly is in the direction of movement 522 preceded by a dryer, the z. B. by UV radiation or IR radiation, the ink 132 on the printing form 102 Dries so that these by the abrasive action of the gas stream 502 can be removed more easily. Alternatively, instead of the dryer, a cooling device may also be provided which cools the printing ink in such a way that it can be more easily removed by the hard material jet.
