Brief description of the drawings
In order to be illustrated more clearly in the technical scheme in the embodiment of the present invention, below the accompanying drawing of required use during embodiment is described is briefly described, apparently, accompanying drawing in the following describes is only one embodiment of the present of invention, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the flow chart of the three-dimensional phantom sheet processing method that provides of preferred embodiment of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiment.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
In prior art for paper surface obtain special effect, the general modes such as printing, embossing, hologram transfer that adopt, but the paper obtaining by printing or embossing does not have third dimension and innervation, paper surface out-of-flatness after processing, deflection and toughness that also can considerable damage paper in embossing processing, reduce the mechanical performance of paper, hologram transfer method work flow complexity, cost are very high.
Main innovate point of the present invention is: a kind of three-dimensional phantom sheet processing method is provided, the deployed three-dimensional phantom coating with higher remanent magnetism is coated on to paper surface, form three-dimensional phantom coating thin layer, at abundant levelling still under undried condition, the magnetic field forming by strong magnetic mould, the features of shape of strong magnetic mould makes the magnitude of field intensity of diverse location on mould not identical, when the paper that scribbles phantom coating thin layer is during by these strong and weak different magnetic fields, the magnetic force that diverse location is subject to varies in size, the effect that phantom pigment in coating is subject to magnetic field is subjected to displacement, the local displacement that magnetic field intensity is large is obvious, the displacement that magnetic field intensity is little is small, refraction and the reflection of coating surface to light that make of these displacements changes, thereby form three-dimensional plantom effect.
Fig. 1 shows the flow process of the three-dimensional phantom sheet processing method that preferred embodiment of the present invention provides, and as shown in Figure 1, three-dimensional phantom sheet processing method of the present invention comprises the following steps:
S1, design need performance three-dimensional phantom figure and according to the strong magnetic mould of this graphic making.This phantom figure, according to client or design needs, can be striped, annulus, polygon, animals and plants profile, various decorative patterns etc. or its combination of different thicknesses, as long as the figure that can imagine all can.Strong magnetic mould is that permanent-magnet material makes, and magnetic force is the bigger the better, and the shape of strong magnetic die surface is corresponding with three-dimensional phantom figure.
S2, phantom coating is coated on to paper surface, fully levelling.Phantom coating is the liquid coating of the materials such as phantom pigment, packing material, solvent, be coated on paper surface by certain mode, phantom pigment is the main matter that realizes the three-dimensional phantom of the present invention, because phantom pigment itself has higher remanent magnetism, can be subject to the magneticaction of strong magnetic mould, thereby form three-dimensional plantom effect.
S3, the described paper that is coated with phantom coating is placed in the magnetic field range of described strong magnetic mould.This process need still carries out under undried condition at the abundant levelling of phantom coating, the effect that phantom pigment in coating is subject to magnetic field is subjected to displacement, the local displacement that magnetic field intensity is large is obvious, the displacement that magnetic field intensity is little is small, refraction and the reflection of coating surface to light that make of these displacements changes, thereby forms three-dimensional plantom effect.Strong magnetic mould is arranged on to the correct position under paper running route, and the relative position of strong magnetic mould and paper surface can be adjusted.
S4, dry.Paper is dried by drying system, finally by cutting or rewinding obtains the finished product paper of sheet or rolling.The conventional dry two kinds of modes that have, the one, volatile dry, is exactly three-dimensional phantom coating during through drying device, and solvent evaporates occurs dry; The second is that ultraviolet (UV) is dry, and while being exactly three-dimensional phantom coating process drying device, the photosensitizer in coating is had an effect, and causes photosensitive resin generation cross-linking reaction, thereby dry.Preferably, the present invention controls the conditions such as temperature, humidity, ventilation by drying system, controls solvent evaporates speed and reaches quick-drying object.
Special needs to be pointed out is, the process that above-mentioned steps S2～S4 is continuously, carries out fast, after being coated with, phantom coating transfers to immediately in the magnetic field range of strong magnetic mould, phantom pigment is subject to the magneticaction of strong magnetic mould, form three-dimensional plantom effect, then the rapid draing effect of drying system can be fixed up three-dimensional plantom effect rapidly.
Preferably, described step S1 is further comprising the steps:
The three-dimensional phantom figure of S101, use Freehandhand-drawing or computer graphical Software on Drawing.The figure of the three-dimensional phantom paper obtaining by processing method of the present invention need to design in advance, this figure determines the features of shape of strong magnetic mould, on the mould that strong magnetic mold shape feature is brought, the magnitude of field intensity of diverse location is not identical, the movement of the decision phantom pigment of magnitude of field intensity, the mobile end reaction of phantom pigment is to three-dimensional plantom effect.
S102, according to described three-dimensional phantom graphic making strong magnetic mould corresponding thereto, strong magnetic mould is roller or writing board shape.Strong magnetic mold shape and coating method have direct relation, for example, adopt in the coating method of roller coat, strong magnetic mould can be made pulley type, and picture and text can also be made seamless picture and text, as required, three-dimensional phantom paper finished product can be made reel or cut into the flat paper of different size; In single paper coated mode, make the strong magnetic mould of suitable flat board according to the size of picture and text, the sheet-fed that the three-dimensional phantom paper finally obtaining is correspondingly-sized, the three-dimensional phantom figure on this sheet-fed can be also repetitive pattern, uses after this sheet-fed can being cut into suitable size.Because neutral body phantom figure of the present invention is any figure that can imagine, so corresponding with three-dimensional phantom figure in order to ensure the magnetic force characteristic distributions on strong magnetic mould, in the stronger region of the three-dimensional phantom of needs, larger to part magnetic force that should region on strong magnetic mould, can order about more phantom pigment to this regional movement; Contrary, in the weak region of the three-dimensional phantom of needs, less to part magnetic force that should region on strong magnetic mould, phantom pigment is less to the amount of this regional movement.Spaced apart by territory, strong magnetic area and territory, weak magnetic area on strong magnetic mould, thus three-dimensional phantom figure on paper, showed.
