Fig. 1 is the preferred embodiment according to equipment of the present invention, utilizes this equipment to perform according to the inventive method.
Detailed description of the invention
Shown according to equipment 1 of the present invention or the machine (such as digital printer) comprising this equipment, for impressing the substrate 2 of heat deformable or impressing the material layer 8 of heat deformable in this substrate.Described equipment comprises front end units 3 alternatively and comprises rearmounted unit 4 alternatively.Described front end units can be the unit for supplying web shape or the substrate of page shape, such as reel uncoiler or page feeder.The substrate be supplied to can carry material layer.Described rearmounted unit can be the unit for receiving through processing substrate, such as reel coiler or page collector, or reprocessing machine.Substrate is moved along throughput direction 5 in described equipment.
Substrate 2 is preferably plastic sheeting.Material layer 8 preferably has toner, pigment, gloss varnish, ink or film.The material layer of based thin film can comprise laminated film.
Substrate 5 enters in the zone of action of applying unit 6 during carrying.Described applying unit can be electrofax unit, ink and/or gloss varnish applying unit, such as, and flexographic printing unit or serigraphy unit, or ink jet unit.Described applying unit can apply one or more pigment, gloss varnish or ink.The pigment applied, gloss varnish or ink are thermoplastic.To attach troops to a unit a post-processing unit 7 also can to described applying unit.Alternately, described post-processing unit is integrated in the applying unit 6' of an expansion.Described post-processing unit can be fixation unit (when electrofax/toner printing) or drier (when flexographic printing, serigraphy or ink jet printing), be such as hot air dryer or UV-drier or IR-drier.When ink jet printing, also can arrange, first print a polychrome figure by (non-thermal plasticity) UV-ink and carry out UV sclerosis, then, thermoplastic aqua type ink is printed on.The latter's (thermoplastic aqua type ink) dried (such as by IR), then, according to the present invention's position-adjustable heating aptly.Described aqua type ink can be latex ink.Be alternative in water, other solvent for ink can also be applied, such as isopar (Isopar).It is very common that, transparent pigment/gloss varnish/ink can also be applied or through pigementation.Described pigment preferably has and is about 1 μm or less average diameter.
Then, substrate 5 enters in the zone of action of imprinter unit 10 during carrying.In the example illustrated, imprinter unit comprises rotary roller 10b, and this rotary roller has received column pressing mold 10a.Alternately, described pressing mold also can be flat-shaped and contact with substrate 2 or material layer 8 by moving up and down.Pressing mold is by being applied on substrate or material layer when pressure is at least light.
Equipment 1 has controllable heater 10c.In the example illustrated, this controllable heater is received in cylinder 10b.Described heater can be controllable IR-radiator, this controllable IR-radiator have on the direction transverse to throughput direction 5 single can the operated thermal treatment zone.Alternately, the described thermal treatment zone can be made up of broadwise controllable hot air supplying apparatus or hot water supply apparatus.Alternately, the described thermal treatment zone can be made up of broadwise controllable electric heater unit.The described thermal treatment zone can by single opening and closing, and/or the described thermal treatment zone can by single control in its power.Described control by means of computer 13 by realizing in this unshowned connection.
Heater 10c allows the deformability improving described substrate 2 or described material layer 8.At this, described pressing mold 10a is heated by position-adjustable aptly, and, substrate and/or material layer by this pressing mold aptly position-adjustable heat.Therefore, described heating realizes indirectly by pressing mold.Can be improve the pliability of substrate and/or material layer by described heating, in other words, substrate and/or material layer become softer and then become and can more easily be out of shape.The thermoplastic medium applied preferably is heated to about 100 DEG C to 200 DEG C, is particularly preferably heated to less than 140 DEG C.
Imprinter unit 10 can have selectively for cylinder 10b to pressure roller 10d.To being provided with controllable heater 10e in pressure roller.Heater 10e can its structure and function aspects corresponding to heater 10c.
The enlarged drawing of Fig. 1 shows substrate 1 or this suprabasil material layer 8 has impression portion 11 or 12 after the zone of action leaving described imprinter unit 10.Miniature impression portion 11 or 12 is created when preferably applying miniature pressing mold 10a.Because the structure of pressing mold 10a is preferably delivered to when only having light pressure through softening substrate or in softening material layer, therefore can be alternative in impression also can shaping (Abformen).Described pressing mold preferably structurized silicone mould 10a, be particularly preferably so-called holographic structure, namely following structure: this structure is used for producing hologram by shaping.Described pressing mold preferably has the transversary in the scope being in about 100nm to about 1mm and has the constructional depth of about 100nm to about 1mm.Apply silicone Shore hardness be preferably between about 20 ° to about 100 °.Alternately, can the elastomer of application class hard.
When toner prints, imprinter unit 10 can be configured to as fixing station traditional in electrofax, but in the metallic roll at fixing station, is configured with structurized pressing mold to be alternative in the rubber bush of Un-structured.At this, to be preferably in by the heating of heater in the scope of about 150 DEG C to about 200 DEG C, to be particularly preferably about 190 DEG C.
Substitute (or additional) and, in heater 10c, also can be provided with pretreatment unit 9.Described pretreatment unit comprises broadwise controllable heater 9a.Heater 9a can be controllable IR-radiator, described controllable IR-radiator have on the direction transverse to throughput direction 5 single can the operated thermal treatment zone.Alternately, the described thermal treatment zone can be configured to broadwise controllable electric heater unit, so-called hot head (Thermokopf).Described hot head can move.Alternately, the described thermal treatment zone is loaded with heat energy by one or more laser instrument or laser array.Described laser instrument can move or the beam of described laser instrument can change to arrive described region in its direction.Described laser instrument can send IR or (when applying coordinated absorber in substrate or in material layer) also can send other wavelength.The described thermal treatment zone individually can be controlled by single opening and closing and/or in the power of this thermal treatment zone.Described control by means of computer 13 by realizing in this unshowned connection.Described pretreatment unit aptly position-adjustable heats described substrate 2 and/or described material layer 8.Described heating is directly and indirectly as realized when heater 10c.Alternately, described pretreatment unit can be integrated in the imprinter unit 10' of expansion.
Each heater 9a, 10c and/or 10e can one-dimensionally/broadwise ground or two-dimensionally/control partly.Except (one dimension transverse direction) the broadwise controllability mentioned before, the controllability of two dimension can also be set.Two-dimensional representation is: not only transverse to throughput direction 5 but also on throughput direction 5.The two-dimentional controllability of described heating (softening in other words) therefore allow deformability not only broadwise (one-dimensionally) and also partly (two-dimensionally) optimize.Controllability in the conveying direction also can be realized by the beat of each heater.
When application one pretreatment unit 9, the spacing of described unit and imprinter unit 10 is so selected, and making the temperature through the substrate of heating or the material layer through heating still enough high, being thermoformed into as possibility described in making.At this, the movement velocity of substrate 2 also can be considered.
