Brief description of the drawings
Fig. 1 is the first step in the transfer method of holographic false proof pattern of applicable gravure positioning overprinting of the present inventionThe structural representation of the laser plate of making;
Fig. 2 carries out second in the transfer method of holographic false proof pattern of applicable gravure positioning overprinting of the present inventionStep is to the exploded view of the 6th step.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
The transfer method of the holographic false proof pattern of applicable gravure positioning overprinting of the present invention, comprises the following steps:
The first step: adopt large format justifying lithographic equipment justifying to make a laser plate A with location pattern B(seeing Fig. 1), the size of location pattern B is arranged layout design according to gravure printing, and the precision of this location pattern B reachesTo ± 0.01mm, make a holographic telltale mark C on the side of each location pattern B;
Second step: adopting thickness is the PET basement membrane of 18 μ m, and is coated with one deck possesses mold pressing on this PET basement membraneThe metastatic acrylic coating of characteristic;
The 3rd step: adopt molding apparatus that the location pattern B on laser plate A and holographic telltale mark C are stamped inIn the epilamellar acrylic coating aspect of PET, make positioning holographic film; Molding apparatus is at holographic roller and mouldPhotoelectric sensor is installed at dandy roll place, fixed with the holography that each positioning holographic patterns on detection and location holographic film is otherPosition mark 2; In the process of impression, first by the standard value input computer of location dimension, then pass through photoelectric sensingUpper holographic telltale mark 2 corresponding to each location pattern on device detection and location holographic film; As it is different to find that there is sizeThe standing standby tension force of automatically adjusting draws stretching to positioning holographic film, or adjusts holographic roller and mold pressing rubber rollSpeed difference reduce this deviation, and detect again adjustment result by the photoelectric sensor of rolling place; All locationAfter the holographic telltale mark that pattern is corresponding is detected, detects data result and will gather and print by computer,Make be less than ± 0.1mm of positioning precision deviation;
The 4th step: the one side on positioning holographic film with location pattern is vacuum aluminum-coated, makes this face form an aluminiumLayer 3, makes positioning holographic transfer membrane;
The 5th step: positioning holographic transfer membrane and paper are arranged on to one and possess detection and localization and stretch and adjust meritOn the compounding machine of energy, paper is 175 grams of Hongta art post paperboards; On this compounding machine, have three place's photoelectric sensingsDevice, be located at respectively between film let off roll and film carry-over pinch rolls, between paper upper inking roller and paper carry-over pinch rolls, roll greatly and rollBetween cylinder and carry-over pinch rolls; On paper upper inking roller, be carved with laser plate on the corresponding printing of holographic telltale mark fixedPosition mark;
The 6th step: by compound to paper 6 and positioning holographic transfer membrane, paper 6 first passes through paper upper inking roller, makes printingTelltale mark is printed on a surface of paper 6, then by the photoelectricity between paper upper inking roller and paper carry-over pinch rollsSensor detects the position of the printing telltale mark 5 on paper 6, and detection signal is calculated to reflectionOn computers, poor if any extremely adjusting immediately speed between paper let off roll and described paper upper inking roller; Meanwhile,Described positioning holographic transfer membrane on film let off roll, through deflector roll and gluing cable roll, makes positioning holographic transfer membraneTransfer face on last layer polyurethane glue 4, by gluing cable roll one side arrange scraper control spread,Make the THICKNESS CONTROL of glue layer 4 at 4~5 μ m, by positioning holographic transfer membrane with there is printing telltale mark 5Paper 6 carries out compound, and after rolling the rolling of swift, positioning holographic transfer membrane and paper 6 are fitted, and makePositioning holographic paper (seeing Fig. 2); The pressure that rolls swift is controlled at 5 ± 0.5kg; Whole positioning holographicPaper compound tense paper travel line speed should be controlled at 60~70 ms/min, to guarantee positioning precision and informationThat feeds back is timely and accurate;
The 7th step: positioning holographic paper has two groups of photoelectric sensors, these two groups of photoelectric sensings entering before baking ovenDevice is the printing location on the holographic telltale mark 2 on detection and location holography shifting film and paper 6 correspondinglyMark 5, and detection signal is transferred to computer by control circuit, adjust on computers holographic telltale markAnd the spacing between printing telltale mark, finally makes holographic telltale mark 2 and paper on positioning holographic transfer membranePrinting telltale mark 5 on 6 is in the same horizontal line overlapping; Control circuit is complete by location under computer recordRight behind the location dimension position of the printing telltale mark 5 on holographic telltale mark 2 and paper on breath transfer membraneData lock; Cause on positioning holographic transfer membrane because tension force is unstable as occurred in process of productionHolographic telltale mark 2 and paper on printing telltale mark 5 contraposition deviations, photoelectric sensor is immediately by signalBe transferred on computer by control circuit, two overlapping marks on computer there will be deviation, at this moment just needThe independent tension force of film let off roll and the tension force of film carry-over pinch rolls adjusted, stretches or speed governing is poor shortens, with thisMake two groups of telltale marks again reach overlapping; The tractive force of film carry-over pinch rolls is 3 ± 0.5kg;
The 8th step: positioning holographic paper is through oven for drying sizing, and this baking oven divides five joint independent temperatures, temperatureBe controlled at 100~110 DEG C;
The 9th step: the PET basement membrane in the positioning holographic paper after sizing is peeled off, be loaded with the most at last location completeThe coating of breath pattern is stayed on paper 6.
The transfer method of the holographic false proof pattern of applicable gravure positioning overprinting of the present invention, it can be controlled effectivelyOn the relative position, transfer membrane of each location pattern of transfer membrane, on holographic telltale mark and paper, printing is locatedDimensional discrepancy between mark, therefore can realize the production of the holographic location of reel transfer paper, simultaneously by joiningThe mold pressing location adjusting process of cover, compound location stretching adjusting process, typographic(al) mark positioning process, location markNote contraposition alignment technique, organize the automatic detection and location mark of standalone sensor more, detection is manually adjusted, is watched automaticallyClothes drive multistage stand alone type automatic tension control device, line technique and the device such as to peel off, and have broken through gravure and have establishedThe bottleneck of standby upper print nest lettering bit patterns, can improve gravure production efficiency, reduce production costs, save moneySource, improving product quality.
Above embodiment is used for illustrative purposes only, but not limitation of the present invention, relevant technologies fieldTechnical staff, without departing from the spirit and scope of the present invention, can also make various conversion or changeType, therefore all technical schemes that are equal to also should belong to category of the present invention, should be limit by each claimFixed.
