Description
Technical field
The present invention relates to a kind of base material, it is used for especially flat-die version or forme flat stamping version especially of printing stencil, and/or be used for printing with cloth especially blanket, particularly compressible or incompressible blanket, and/or be used in printing process especially offset printing process participating in another surface of printing operation, also relate to especially offset printing device of a kind of printing equipment that comprises described base material, and a kind of printing cloth that is used to print out-of-flatness printable fabric, corrugated board.
Background technology
In printing technology, knownly provide intermediary element in the unit in printing, it can treat the unevenness of compensation printable fabric upper surface in the process of watermark image in transfer.In all conventional typographies, image to be printed is applied on the printable fabric in the inside of printing unit by the roll extrusion of cylinder, and cylinder shifts image and leading printing material to be printed.Thereby image to be printed results from printing stencil or the forme, and finally can be delivered on the printable fabric from transfer cylinder.
Such as protruding India and China, for example with regard to flexographic printing, adopt printing stencil or forme in the technology of directly printing, can directly image to be printed be applied on the printable fabric by it with high-order print surface.
With regard to offset printing, just a kind of indirect printing technology, the problem that is worth in the general flat stamping technology discussing is, is treating that watermark image is transferred to and being called on the transfer cylinder that prints blanket cylinder of colorant by printing stencil or forme with form.The surface of printing stencil or forme promptly scolds aqua region to be connected according to image to be printed and oleophylic, and the oleophylic colorant that applies of inking unit just sticks to herein like this.Image to be printed then is printed blanket cylinder, more precisely, is transferred on the printable fabric with cloth by the following printing that is stretched on the printing blanket cylinder.
With regard to offset printing, just a kind of indirect printing technology treats that watermark image is to transfer to by printing stencil to be called on the transfer cylinder that prints blanket cylinder.Treat that watermark image then is transferred on the printable fabric by described cylinder.Usually, on the printing blanket cylinder, be applied with a flexible layer.In common offset printing process, adopt so-called printing with cloth or blanket for this reason.Printing is stable in its extension plane with the size of cloth, but transversely can be out of shape on described plane.It can be compressed along its thickness direction to a certain extent.With regard to this point, known compressible stratum is set at the inside of printing with cloth.
Flexible layer is applied on the printing blanket cylinder usually; In common offset printing process, use so-called printing with cloth or blanket, it is dimensionally stable in its extension plane basically, but transversely can be out of shape on described plane.Printing also can be compressed along its thickness direction to a certain extent with cloth.In this regard, known compressible stratum is set at the inside of printing with cloth.Image to be printed is deposited on the printable fabric with the form of cloth with colorant by described printing, for example be deposited on printing paper or the cardboard of undertaking the printing of on.
Be used for the blanket of offset printing or printing and need be used for shifting at offset printing process with cloth and treat watermark image, particularly, also be used to compensate the smooth place of air spots of printable fabric.Because printing stencil or forme in the offset printing are made by metal sheet or film usually, so they self can not adapt to the surface texture of printable fabric fully.
Be pressed against on the counter-pressure cylinders for adapting to for improving the surface texture that printing quality is the printable fabric of necessity, must will printing with cloth by the printing blanket cylinder with high relatively pressure; This point can not be avoided with cloth by using so-called compressible printing, because these printings only have high slightly metamorphosis than common printing with cloth with cloth, needs quite high pressure equally.
With regard to printing uneven printable fabric, nature limits to some extent to conventional offset printing; On the one hand, printing only has limited deformability with cloth, so just need be pressed onto fully on the printable fabric with cloth printing, can received printing quality with maintenance, and on the other hand, the stability of printable fabric under load also is limited.
So, for example with regard to printing corrugated cardboard, just produced the peculiar problem that an internal structure with corrugated board interrelates.Owing in corrugated board, between two protective layers, be provided with a corrugation articulamentum with weight reduction, so corrugated board does not constitute homogeneous material.The protective layer of use in this corrugated board top and bottom only is on some point or forms row, in addition, is connected to each other by the corrugation intermediate layer that is offset mutually on two ends.When loading a corrugated board, finally produce uneven situation from the teeth outwards; Particularly, each protective layer is flexible in the zone between the tie point with corrugation intermediate layer, thereby flexible in being installed into these zones the time.In the loading procedure of typography, finally can produce disadvantageous relatively situation for the homogeneous printing.
Thereby, known in flexographic printing, a kind of pliable and tough and compressible liner is fixed in printing stencil or forme below.Here, draw a kind of like this fact, just, printing stencil or forme self are incompressible, promptly are rigidity, and liner might move printing stencil or forme with respect to masterplate cylinder (=printing stencil cylinder or plate cylinder).For example a froth bed is set to liner, and described froth bed is applied on the loadable tension force liner.By loadable tension force liner, flexible liner just can be stretched on the printing stencil cylinder or with forme with printing stencil simultaneously and be stretched on the plate cylinder, does not stretch thereby do not expect to have longitudinally.
So, printing stencil or forme can be deferred to the last irregular point in printable fabric surface to a certain extent.But, must must tolerate that the change of printing quality is bad this moment, and bad printing stencil or the forme of just causing inevitably of the change of quality is out of shape like this; This also depends on printing and the not well-proportioned usually distribution of non-printing zone on printing stencil or the forme; And printing stencil or forme are also very difficult with respect to the alignment of different printing color.
With regard to offset printing, this method is not known as yet.What recognize in the reality is, the printing on the printing blanket cylinder with cloth below tensioning so-called make-ready lamella is arranged.But, these make-ready lamellas only are used for so-called preparatory function, and the circumference that is printed the printing blanket cylinder that covers with cloth so just should be adjusted to condition required in the typography.
In addition, only from so-called compressible printing cloth, adopt said method similar methods a kind of and at printing stencil or forme lower berth liner.By only under quite high pressure, reducing thickness compressible printing is out of shape with cloth.Described printing with in the cloth for also just in printing operation, destroying corrugated board before fully being out of shape with cloth printing naturally with the necessary distortion that is complementary of the surface texture of corrugated board.For this reason, in offset printing, there is not known method to come in printing operation, corrugated board to be added realization in man-hour pressure distribution highly uniformly.
In case the wheel tumbler tube of printing operation is made such as metal by hard material usually in the participation offset printing process, the so top described shortcoming and defect of example will exist at large.Printing stencil or forme also by solid material for example metal make such as aluminium, zinc etc. or plastics.Because these materials are stable dimensionally, treat unevenness place and the uneven material that watermark image has negative effect so will produce.In addition, in case there is not screen resilience to come tolerance balancing, the rigidity of so described material will cause printing stencil or forme to be difficult to change.
Summary of the invention
For this reason, the objective of the invention is to improve like this offset press of described type, promptly improve image to be printed, more easily change forme and as far as possible on irregular printable fabric, particularly on corrugated board, improve the quality for the treatment of watermark image as far as possible sooner.Therefore, the objective of the invention is in offset printing on the surface of printable fabric, it is high and treat watermark image uniformly for example to produce quality on roll web or corrugated board; Here, for example roll web or corrugated board should not be subjected to the mechanical failure of any way to printable fabric.
Described purpose is that especially offset printing device and printing with claim 15 feature realize with cloth by the base material with claim 1 feature, printing equipment with claim 13 feature.
Favourable structure of the present invention and suitable improved feature are described in the corresponding subordinate.
The invention provides a kind of base material, it is used for especially flat-die version or forme flat stamping version especially of printing stencil, and/or be used for printing with cloth especially blanket, particularly compressible or incompressible blanket, and/or be used to participate in another surface of typography.Because described base material is designed to a removable compound, it can all can be compensated so participate in weak point, dimensional tolerance and the uneven material of typography parts with respect to separately wheel tumbler tube or cylinder separately strain diametrically.So just can realize homogenizing and improving image to be printed.
Except improving printing quality, surprisingly can easily add equipment by base material of the present invention to offset printing device, described base material is as a securable liner, especially be configured in the compound with the cloth liner as securable printing stencil liner or forme liner, and/or as securable printing.By printing stencil or forme are installed on plate cylinder, base material is because of having (radially) elasticity, so can compensate possible dimensional tolerance between printing stencil or forme and the plate cylinder.Therefore, by utilizing the corresponding yield force of higher active force and base material, printing stencil or forme can be fixed on the plate cylinder tightly.
For the printing blanket cylinder, the technical staff in the printing technology will appreciate that, is in one example can be in typography to improve printing by printing with the flexible parent metal below the cloth to print metamorphosis that blanket cylinder directly makes progress with cloth.Employing also can realize metamorphosis with respect to compressible printing with the metamorphosis less action force of cloth.Meanwhile, keep the longitudinal stability of good printing, just can guarantee good printing quality and in offset printing, on irregular surface ratio such as corrugated board, print with cloth.
From context, be derived from other technological advantage of offset printing method in addition; Particularly, can use cheap printing stencil or forme, and easily carry out polychrome alignment.
According to the creative especially improvements of described base material, compound is made by at least one compressible stratum and at least one incompressible stratum.
The deficiency, dimensional tolerance and the uneven material that participate in the printing operation parts can compensate by compressible stratum, and its preferable configuration is one can reverse compression function layer.So just can realize homogenizing and improving image to be printed.
Because compressible stratum and incompressible stratum link together, so can guarantee simultaneously that base material is advantageously used, base material just can especially fully stably be fixed on the cylinder that participates in typography like this.In addition, compressible stratum can improve composite materials stability on the whole with being connected of incompressible stratum, and the active force in the compressible stratum only can cause the limited distortion of base material like this.
According to a preferred embodiment of the invention, the compressible stratum of base material can be a poromerics, preferably has perforate.The compressibility that material is regulated in the permission of foam type honeycomb to a certain extent on request; If the micropore compressible stratum is formed by polyurethane foam aptly, will produce so and have desirable compressible high-drag.Base material can be with respect to being different from compressible other character, and for example its anti-tear pulling force and/or chemical stability are optimized selection.
The compressibility of integral material promptly produces by its loose structure, and though its can by the user regulate according to corresponding requirement to a certain extent and base material how.
With regard to incompressible stratum, it is constructed to the carrier layer of dimensionally stable in creationary improvement, especially the plate of a dimensionally stable or film, described incompressible stratum can be advantageously to go up in whole or in part by at least a plastics material that forms of polyester preferably.Described Master Cost is cheap, have high intensity and have flexibility with respect to bending simultaneously, perhaps dimensionally stable aspect anti-tractive force.In addition, described material can easily combine with other material to form composite.
According to a preferred embodiment of the invention, base material can comprise one or more layers, can especially comprise a kind of jointing material, a kind of packing material and/or other auxiliary material in the layer.Jointing material is used to connect adjoining course at this moment, promptly is particularly useful for connecting incompressible stratum and compressible stratum.Using packing material is other character that can not influence material in order to make base material reach desirable volume (--＞layer thickness).In addition, other layer of auxiliary material that provides can for example improve with carrying being connected of cylinder, with being connected of printing stencil or forme, with print with being connected of cloth etc., perhaps can be used on certain outer surface.
Base material comprises at least two compressible stratums in its proprietary structure, thereby these layers preferably have different structures with respect to base material and/or with respect to structure (porosity) and/or different thickness.The performance of base material can be when importing pressure the combination of several compressible stratums and controlled.Thereby, can for example directly contact and realize pressure peak and the good local absorption of active force peak value, and hard (thinner) material on the lower position can cause bigger distribution of forces to bigger zone with printing stencil or forme by thicker or firmer compressible stratum.
In the several proprietary structure of base material, base material comprises at least two incompressible stratums, and it still has different structures with respect to base material and/or with respect to structure and/or different thickness.The performance of base material still is subjected to the control of these defining standards naturally.Thereby, but especially optimal design and load-carrying unit directly the layer of contact be connected being used to; This means that these materials for example have enough (anti-tear drawing) intensity and/or enough thickness to be positioned on the cylinder.On the other hand, the layer of base material inside can minimize to the thickness that is enough to finish its function vector in whole compound.
The integral body of planar substrate (layer) thickness can be about 0.5 millimeter to about 4 millimeters, especially is about 1.5 millimeters to about 2.5 millimeters.Bed thickness like this can be gone up existing printing equipment for base material is equipped with subsequently, and not have the variation of essence, so that guarantee the uneven place of compensation in a predetermined manner.
Printing equipment also is a protection theme of the present invention, the offset printing device of printable fabric irregular especially in particular for print surface, that preferably make by paper or cardboard, and it comprises
-one plate cylinder, tensioning has especially flat stamping brush masterplate of a printing stencil on it, or a forme, especially a flat stamping version;
-one printing blanket cylinder, on it tensioning have one in extension plane printing cloth, the especially blanket of dimensionally stable basically, particularly compressible or incompressible blanket; And
-one counter-pressure cylinders.
Described printing equipment is characterised in that plate cylinder and/or printing blanket cylinder and/or counter-pressure cylinders and/or other surface that participates in printing all scribble above-mentioned base material in its surface.Just because of base material has the performance of being set forth, so can utilize described printing equipment to realize the printing effect of better quality.In addition, when base material is fixed on the plate cylinder that carries printing stencil or forme, subsequently can be simply, intricately is equipped with different printing stencil or forme for described plate cylinder.
Printing with claim 15 feature has brought following advantage with cloth.Particularly by special use printing with cloth below or inner flexible liner bed course can improve special-purpose printing and in typography, printing the metamorphosis that blanket cylinder directly makes progress with cloth.Employing also can be out of shape with the little active force of the distortion of cloth than known compressible printing.Meanwhile, keep the longitudinal stability of special-purpose printing, thereby guarantee good printing quality with cloth.Thereby, can be in offset printing for example print on the out-of-flatness surface of corrugated board at any material of undertaking the printing of.Also have many other technological advantages that are derived from offset printing process.Particularly, these advantages show as the printing stencil of use cheap, carry out polychrome alignment more simply.

The specific embodiment
Same or analogous structure, element or feature adopt identical representing with reference to label among Fig. 1 to 5.
Represented to be used for the main element of the offset press of rotary printing among Fig. 1.Printed original is that first rotary drum is so-called printing stencil or a forme 11 on the masterplate cylinder 10 in form; Described masterplate cylinder 10 also is called plate cylinder sometimes.The surface of forme 11 is made up of hydrophilic (promptly to the water close friend) or oleophylic (promptly to the grease close friend) zone corresponding to the contoured surface of undertaking the printing of, the oleophylic printing colorant that applies of inking system (being clearly visible, not shown in Figure 1) only adheres on the corresponding oleophylic zone like this.By adopting the water emulsion colorant, the conversion bond condition, oil is just scolded in the zone that will be imprinted on like this on the forme 11, also is the material of scolding oil on applied.
The offset printing method of Fig. 1 and 2 (--＞the first embodiment) demonstration is by so true improved, promptly, base material 100 is applied between plate cylinder 10 and the forme 11 and/or between blanket cylinder 12 and the blanket 13 and/or on the counter-pressure cylinders 15, described material is to form by the compound of being made by compressible stratum and incompressible stratum.
The installation situation of having represented plate cylinder 10 and blanket cylinder 12 the above base material 100 among Fig. 1.Uneven or the uneven material of plate cylinder 10 and/or forme 11 can be repaired and compensation by base material 100, thereby has improved the image that will print.In addition, forme 11 is installed on plate cylinder 10 easily, has also just been optimized the equipment that adds of forme 11.It seems that at this point base material 100 allows seal speed high.
Fig. 2 shows the typical layers structure of base material 100.Under situation shown in Figure 2, the base material 100 that is arranged on the carrier 19 shows three kinds of different layers 16,17 and 18 that are in sandwich.
The layer of foot is a kind of perforate (offenzelliges) polyurethane bed courses 18 with carrier 19 contacted layers promptly also, about 0.51 millimeter of its thickness.The intermediate layer is a polyester film 17, and it is a kind of hard, incompressible plastic material.Sandwich is about 1.02 millimeters open-cell polyurethane bed course 16 by a thickness and covers.About 2.10 millimeters of the integral thickness of base material 100.
Thereby, the base material 100 among Fig. 1 and 2 first embodiment has been arranged, hard and compressible substrate can be used for the forme of offset printing, and the forme that is used to have the mixed printing of flexo unit and offset printing unit.Then, the sandwich of substrate is formed by the compressible foam bed course that has different embossings and plastic plate or plastic sheeting.One or more different especially polyurethane bed courses can make up mutually with one or more different especially plastic plates or plastic sheeting: the thickness that polyurethane bed course and/or plastic plate or plastic sheeting combine in interlayer also can be different.
Fig. 3 has schematically shown second embodiment of offset printing unit of the present invention.Described offset printing unit has a counter-pressure cylinders 15, a printing blanket cylinder 12, a plate cylinder 10, also is furnished with a process color materials device 21 and a dampening device 22 on described plate cylinder 10.
Among Fig. 4, printing zone among Fig. 3 is for this reason between printing blanket cylinder 12 and counter-pressure cylinders 15, and the rough diameter ratio that is become between the drawn printing blanket cylinder 12 in drawn counter-pressure cylinders 15 and Fig. 3 and 4 tops below Fig. 3 and Fig. 4 needn't be corresponding to actual value like this.
Printable fabric is illustrated on the counter-pressure cylinders 15 among Fig. 4, described material in described second embodiment, be configured to corrugated board 14 '.A lower protective layer 141 of described corrugated board 14 ' below Figure 4 and 5, show ', and have above the Figure 4 and 5 protective layer 143 on '; Two protective layers 141 ', 143 ' by a corrugated articulamentum 142 ' interconnect, like this lower protective layer 141 ' just be adhesive in articulamentum 142 ' lower limb on, and go up protective layer 143 ' be adhesive in articulamentum 142 ' top edge on; Connect Just because of this, just formed a kind of highly stable printable fabric that is particularly useful for packaging material usually.
In addition, on printing blanket cylinder 12, be configured to print base material 100 with the cloth liner ' just in time be positioned at for 13 times with cloth on the surface of printing blanket cylinder 12 in printing.Described base material 100 ' by a non-stretching basic unit 17 ' and one place described basic unit 17 ' on flexible protective layer 16 ' form.Though non-stretching basic unit 17 ' can be solid plastic sheeting, flexible protective layer 16 ' preferably a kind of layer of making by the foam that has certain specification.
Since have described non-stretching basic unit 17 '; so be configured to print base material 100 with the cloth liner ' can be stretched in cloth 13 with printing and print on the blanket cylinder 12, foam (--＞flexible protective layer 16 ') tightly with plastic sheeting (--＞non-stretching basic unit 17 ') links together like this.Therefore, the surface of printing blanket cylinder 12 is similar to common printing blanket cylinder.
Among Fig. 5, at length represented the cutting part of Fig. 4.On below the corrugated board 14 ' still be positioned at.Self and corrugated board 14 ' the printing that adapts of textured surface with cloth 13 be positioned at corrugated board 14 ' above.Differences in height on below being illustrated in respect to part, printing blanket cylinder 12 surfaces by be called froth bed, be configured to print base material 100 with the cloth liner ' flexible protective layer 16 ' compensation.Foamed material corrugated board 14 ' the surface be that solid some position is compressed, printing is just stooping during corresponding deformation through bending with cloth 13 like this.
Printing with cloth 13 can corrugated board 14 ' two solid tabs between intermediate space in defer to corrugated board 14 ' deformable surface, flexible protective layer 16 ' just can realize this compensate function like this because of the froth bed structure.
Just because of corresponding adjustment has been done in presswork, promptly determine the functional distance of printing blanket cylinder 12 and counter-pressure cylinders 15, or just because of for being configured to print base material 100 ' different froth bed of selection, so existing printing equipment can be used for printable fabric surface irregularity, that the quality difference is very big with the cloth liner.With regard to the printable fabric of relatively easy compression such as the corrugated board 14 shown in second embodiment of Fig. 3-5 ' with regard to, select than the hard relatively material of printing during such as the embossing solid slab softer foamed material be necessary.
With regard to excellent function and necessary printing quality, be configured to print base material 100 with the cloth liner ' thickness be important.Basically, thickness about 0.5 millimeter to about 3.00 or 4.00 millimeters base material 100 ' in the range of application of considering.With regard to the application technology of known printable fabric, preferentially select thickness about 1.00 millimeters to about 2.00 millimeters base materials 100 '.With regard to foamed material, preferred foamed material that can reverse compression in many effects circulation.Here, preferably adopt a kind of foamed material of perforate.Described foamed material is compared easier compression with known printing with the closed pore layer in the cloth.
Special-purpose printing is preferably formed with cloth by a kind of common printing with cloth 13,70, because basic unit 17 ' also can embed printing with in the cloth.Described open-cell foam materials preferably is put into the existing non-stretching layer of knitting and goes up or be put into printing with in the heteroid basic unit or carrier layer of cloth.Described active layer 13 ' can also be applied to again on the described foamed material.Like this, we just obtain such advantage, promptly with regard to respect to common printing with cloth, to the special use printing with regard to the resistance of the still intrinsic tension force of cloth 70, special-purpose printing is stretched surperficial flexibilities transversely with cloth 70 and is obtained sizable raising, especially its active layer 13 ' in (Fig. 4).
Can make simple modifications with the running of cloth 70 to special use printing, because only the common printing of a part is laminated in base material 100 ' last or the lower floor with cloth.And, a part to printing with cloth form tensile strength following knit layer can be from common printing with removing the cloth.Like this, just print the dimensional stability of using cloth in the guarantee effect zone fully.A kind of make by this way its printing at action plane reduced stiffness transversely can be used as with cloth an active layer 13 ' be applied to base material 100 ' on or the protective layer 16 of lower floor ' on.Like this, the special use of the above-mentioned type printing with cloth 70 just simply mode produce, and equally simply mode is stretched in and prints on the blanket cylinder 12.
In addition, in the zone of special use printing with the clamped edge of cloth 70, a reinforcement can be set, clamping in the printing operation and special-purpose printing all can be improved with the use of cloth 70 like this.Here, in that active layer 13 ' and after lower floor installed, special-purpose printing was flattened to being applicable to the thickness that prints clamping device in the blanket cylinder 12 in its end with cloth 70.The clamping end of Chan Shenging also can have the reinforcement that form is metallic rod or other suitable reinforcement form like this; so that avoid being penetrated into protective layer 16 ' or foamed material in printing process in material protective layer is had a negative impact, special-purpose printing can have a sealant with the forward edge of cloth 70 clamping ends.So, special-purpose printing is illustrated with cloth 70 and comprises a large volume zone of action, its flexible active layer 13 by the lower floor that has suitable compression ' form.But in addition, special-purpose printing can be stretched on the printing blanket cylinder 12 with cloth is the same with the common printing of known thickness with cloth 70.
The special use of described large volume printing can change in wide region with the structure of cloth 70, and raw material (common or other printing with the lower floor or the lamina propria of cloth, open celled foam) and structure thereof have just constituted general condition like this.Can adopt known conventional equipment realize active layer 13 ' and non-stretching basic unit 17 ' between connection, or active layer 13 ' and be used for producing special-purpose printing with printing between the last additional common bearing bed of cloth 70 with the embedding of cloth foamed material.
