A kind of printing process of cigarette-brand
Technical field
The invention belongs to print field, relate to a kind of printing process of cigarette-brand.
Background technology
Intaglio printing press is widely used in the printing packaging industry.Intaglio printing is a kind of direct printing process, and it is imprinted directly into printing ink contained in the intaglio plate pit on the stock.The forme of intaglio printing is made up of the surface of corresponding with the original copy picture and text one by one pit and forme.During printing, printing ink is filled in the pit, with doctor the printing ink on forme surface is wiped off then, and machine is transferred to the printing ink in the pit on the stock by the pressure effect, finishes printing.During the intaglio printing press printing coloured image original copy is divided into several monochrome images and makes a plate, be responsible for finishing a kind of printing of color at each printing element of printing machine.When stock during through the printing equipment of each print color unit, the forme of each printing element is transferred to the stock surface with monochrome image and is carried out overlappingly again, forms coloury coloured image.In recent years, very big variation had taken place in domestic tobacco business.The reorganization of cigarette enterprise and integration, the especially raising of cigarette brand concentration degree mean that the output of single brand, single trade mark cigarette will be improved largely, and this just requires tobacco bale printing enterprise that large batch of cigarette package can be provided fast.Therefore, tobacco bale printing enterprise must have certain production scale and production capacity.At present, the development trend that effectively is combined into the tobacco bale printing of multiple material, multiple typography.Intaglio printing has many advantages, as the production efficiency height, and the form and aspect high conformity, the adaptability of printing material is good, on the spot, specially aspects performances such as look, gold (silver) ink print are good, can satisfy the strict demand of tobacco bale quality aspect, intaglio printing press becomes the general choice of tobacco bale printing enterprise.In addition, the quality testing of tobacco bale printed matter also will further be reflected in printing smell, packing machine adaptability, fade, aspect such as the feature of environmental protection, and gravure also has more advantage than other typographies in these areas.Therefore, choosing of gravure equipment just becomes the topic that tobacco bale printing enterprise extremely pays close attention to.Intaglio printing press mainly is divided into three parts: uncoiling part, printing, cut and the cross cutting part. and printing is the core of intaglio printing press, finishes versicolor printing, chromatography and oven dry.
Red seven smoke signals mark is popular cigarette-brand widely on a market, this cigarette-brand colour printing brush such as red, black adopt the reel gravure printing, speed can reach 150 meters/minute, common drying mode carries out drying to printing ink, red seven smoke signals target patterns adopt in individual screen printer printing, 2000/time, also be to adopt common UV to solidify drying mode.
The technical problem and the shortcoming that exist are: 1, the speed of screen printer is that the speed of 1/7, two kind of mode of printing of intaglio printing press does not seriously match, and the silk-screen mode of printing seriously lags behind the gravure printing mode; 2, the drying mode of silk-screen is disposal solidifying, does not reach the technological requirement of product; 3, printing registration and quality are not too desirable.
Summary of the invention
The invention provides a kind of printing process of cigarette-brand, the speed that it has solved screen printer in existing red seven smoke signals head-stamp brush processes is 1/7 of intaglio printing press, the speed of two kinds of mode of printings does not seriously match, and the silk-screen mode of printing seriously lags behind the problem of gravure printing mode; The drying mode of silk-screen is disposal solidifying, does not reach the problem of the technological requirement of product; Printing registration and quality are not too desirable problems.
A kind of printing process of cigarette-brand may further comprise the steps:
(1) adopt the printing of reel intaglio printing press, the running parameter of adjustment intaglio printing press before beginning to print:
A: the ink cell degree of depth of gravure is adjusted to 0.060-0.070mm, and cable angle is adjusted to the 30-34 degree, netting twine be decided to be the 70-80 line/centimetre, chromium layer hardness is adjusted to 879-883HV, the print speed printing speed of intaglio printing press is adjusted to 150 meters/minute;
B: the adjustment of the drying device of the embossed printing ink glazing last of the same colour of intaglio printing press: adopt the UV drying device;
(2) open intaglio printing press printing cigarette-brand.
Further, a preferred embodiment of the present invention: described steps A is: the ink cell degree of depth of gravure is adjusted to 0.065mm, cable angle be adjusted to 32 the degree, netting twine be decided to be 75 lines/centimetre, chromium layer hardness is adjusted to 891HV, the print speed printing speed of intaglio printing press is adjusted to 150 meters/minute.
Further, a preferred embodiment of the present invention: described UV drying device is controlled power at 68kW by controller.
Further, a preferred embodiment of the present invention: described UV drying device is 4 groups of UV fluorescent tubes, and the power of described every group of UV fluorescent tube is 17kW.
Beneficial effect of the present invention:
Printing process of the present invention just can print out the effect of serigraphy by intaglio printing press, and black bed thickness is real, and concave-convex sense is very strong, and can improve 7 times production efficiency and 2 times alignment precision.
Printing process of the present invention adopts the ink setting mode of earlier quick-fried back curing more can embody the process characteristic of product.
