Abstract
The present invention of a process to remove UV presswork mist relates to printing technical field, in particular to a process solving the problem that mist is easy to form between the presswork and the plastic film after the UV gloss oil of the presswork is wrapped by plastic film in the printing packaging industry; the present invention is characterized in that in the process of adopting the printing UV gloss oil, sodium fluoride which can evenly disperse the UV gloss oil system is added into the UV gloss oil to enhance the uneven sense of the gloss oil surface and further enlarge the presswork gloss oil surface area; the surface tension is also greatly reduced to form a certain clearance microscopically between the external plastic packaging film and the presswork surface which effectively realizes the object of preventing mist from congregating. The present invention can not only ensure the product surface luster and abrasive resistance but also successfully solves the problem of aggregated mist in the industry.
Description
Technical field:
The present invention relates to printing technology, form the solution technology of fog on particularly a kind of printed matter between UV gloss oil and the plastic sheeting.
Background technology:
For improving the surface gloss and the wearability of printed matter, printing industry generally takes to carry out UV gloss oil glazing to promote product decoration class after picture and text are completed for printing in the middle of the industry.When layer of plastic film can be packed in the printed matter outside usually again by producer in the reality when packed products (as cigarette pack); but when film high temperature hot melt adhesion process, easily condense fog at product surface and plastic sheeting inner face; cause local printed matter picture and text to look fuzzy outward; influence product entire package effect, and become the difficult problem of puzzlement industry always.
Summary of the invention:
The objective of the invention is to overcome above technological deficiency, provide a kind of and can eliminate, suppress UV glazing class printed matter is prone to fog after the plastic sheeting encapsulation technology.
The present invention is by the following technical solutions for achieving the above object:
The present invention adopts after the folded look of picture and text is completed for printing in general typography, at printing UV gloss oil operation stage, by in the UV gloss oil, adding a kind of polymeric solid flour---sodium fluoride that can be dispersed in the UV gloss oil system, and the concave-convex sense on enhancing gloss oil surface, further enlarge printed matter gloss oil surface layer, and reduce its surface tension greatly, make on microcosmic, to form certain interval between outer plastic film and the printed matter surface, thereby reach the purpose that prevents that fog from assembling effectively.
Processing step of the present invention is: the gravure printing roller (the engraved lines number is that 85L/cm, carving depth are advisable with 23-25 μ m) of at first accurately making the special use of a UV glazing.For guaranteeing UV gloss oil preferable levelability of when printing, adopt that the black cylinder circulation that has adjustable assisted heating device goes up China ink, the gloss oil viscosity is controlled between 20-21s by the temperature setting switch of regulating assisted heating device.Select the macromolecular material sodium fluoride of a kind of particle diameter simultaneously, join in the UV gloss oil and and rotate with stir (adding proportion of sodium fluoride is advisable with 3%) by the pump motor at 5-7nm, high temperature resistant (fusing point is more than 200 ℃).For guaranteeing the thorough curing drying of UV gloss oil, must careful selection in the production with the UV gloss oil in important composition---the suitable ultraviolet lighting shot-light of light trigger absorption spectrum source (general wavelength is 365nm), the while is calculated its power density and general power according to the machine speed science; According to our repeatedly repetition test, when solidified between during less than 0.5 second, UV power of lamp tube density should be greater than 120w/cm, the ultraviolet source general power should be not less than 40kw.
Beneficial effect: the present invention is by strict above technological parameter of control and work condition environment, not only can be under the prerequisite that guarantees product surface glossiness and wearability (can pass through printing ink frictional experiment machine testing), and successful solution fog assemble this industry difficult problem.
The specific embodiment:
The present invention is after the folded look of picture and text is completed for printing in general typography, adopting A at printing UV gloss oil operation stage, make the UV ferrotype plate,---B, raw material mix---C, printing---D, solidify dry technology, thereby reach the purpose that prevents that fog from assembling effectively.Its concrete processing step is as follows:
A, making UV ferrotype plate:
Accurately make the gravure printing roller of UV glazing special use, the engraved lines number is that 85L/cm, carving depth are advisable with 23-25 μ m, and glossiness and wearability all reach requirement.
B, raw material mix: select the macromolecular material sodium fluoride of a kind of particle diameter at 5-7nm, high temperature resistant (fusing point is more than 200 ℃), with the ratio (adding proportion of sodium fluoride is with 3%) of 20kgUV gloss oil adding 600g sodium fluoride, rotate to stir by the pump motor.Sodium fluoride can partly float on the gloss oil laminar surface but can not influence its glossiness and wearability when gloss oil solidifies, making has certain space on microcosmic between film and the cigarette-brand, and generation can evenly absorb the effect of heat, changes into liquid state and be unlikely to local accumulation.
C, printing:, control the above-mentioned material viscosity that stirs and between 20-21s, print by the UV ferrotype plate by regulating the heating apparatus of recirculation ink cylinder.
D, curing drying: for guaranteeing the thorough curing drying of UV gloss oil, must careful selection in the production with the UV gloss oil in important composition---the suitable ultraviolet lighting shot-light of light trigger absorption spectrum source (general wavelength is 365nm), the while is calculated its power density and general power according to the machine speed science; During less than 0.5 second, UV power of lamp tube density should be greater than 120w/cm when solidified, and the ultraviolet source general power should be not less than 40kw.
