Abstract

A container with printed colour pattern and able to be deformed arbitrarily and its making method are disclosed. It features that on its irregular external surface there is accurately restored colour pattern. Its making method includes making plate of said pattern, that is, setting up the planar network on the metal sheet which can become regular coordinate lattice after punching and making the plate of deformable pattern at the correspondent position or regular coordinate lattice and the planar network of metal sheet. Its advantage is easy design of container shape and pattern.

Description

Be out of shape deep-draw color printing container and preparation method thereof arbitrarily

The present invention relates to a kind of container and make particularly a kind of any distortion deep-draw color printing container and preparation method thereof.

Chinese patent CN-11847572 discloses a kind of two sheet type food can and surface printing and plate-making method thereof, it is to be benchmark with the basic circle, center with basic circle is that parallel is made in the concentric circles center of circle, be that radial line is made netted line chart with the radiant rays outside again from the center of circle, dash then and roll into jar, again literal or pattern are determined relevant position at can body, thereby on the counter correspondence position of painting the netted line chart in plane, the pattern that obtains printing and the master of literal, but this method only is fit to the circular foods jar, as make square jar, when oval can or other deep-draw color printing container that is out of shape arbitrarily, the netted line chart that this method obtains through dash roll into container after, on sheltering oneself, will obtain random random netting twine, thereby printed patterns on can't obtaining to shelter oneself and the literal correspondence position on the netted line chart in plane, also just can't prefabricated color printing version, make the outward appearance and the design of deep-draw color printing container and further popularize the restriction that development has been subjected to greatly thus.

The objective of the invention is to provide for the deficiency that solves above-mentioned technology a kind of can be on the plane before its distortion in anomalistic object or the irregular deformation zone arbitrarily any distortion deep-draw color printing container and preparation method thereof of the prefabricated distortion pattern that can accurately reduce.

In order to achieve the above object, design-calculated of the present invention is out of shape deep-draw color printing container arbitrarily and comprises that irregular deep-draw shelters oneself, and the outside face that irregular deep-draw is sheltered oneself is provided with the pattern of reduction, and described pattern comprises figure or literal and combination thereof.The method for making of this any distortion deep-draw color printing container is the at first distortion pattern plate-making to reducing, be printed on the sheetmetal then, punching out container again, the method for platemaking that it is characterized in that the distortion pattern that can accurately reduce at first be provided with on the sheetmetal after punching press can the formation rule coordinate grid planar network, this planar network is made up of the intrinsic curve that ray reaches and this ray is perpendicular along punching press deep-drawing deformation direction, be similar to vertically comprising here vertical, again the pattern that will print on the regular coordinate grid of container with planar network in the distortion pattern that presets of correspondence position make a plate.At this, described planar network setting is that first planar development to irregular container carries out the deformation rule regional assignment, delimit affine deformation, nonaffine deformation and indeformable each zone, again the network segmentation is carried out in each defined area, required definite mesh coordinate directly is set on each non-deforming region; To the zone of each affine deformation, divide vertical affine deformation and laterally affine deformation and longitudinal and transverse two-way affine deformation, determine the alternation digit rate and carry out the grid line distribution to be provided with by the affine deformation direction that stretches or compress; Each nonaffine deformation zone is divided into a plurality of relative affine deformations zone again according to the pattern accuracy requirement, determine the intrinsic curve segments of required reduction precision, in each relative affine deformation zone, distribute by each simulation alternation digit rate intrinsic curve and relative vertical ray with intrinsic curve are set.In addition, network segmentation to each nonaffine deformation zone, can also be by the accuracy requirement regulation segments of determining with intrinsic curve, simulate to distribute by the alternation number of determining for every section and be provided with, along the punching press drawing direction simulation ray of determining density is set then, after punching press, constantly revise setting, make the simulation ray relative with intrinsic curve vertical, form can on container, be reduced into the planar network of regular coordinate grid after the punching press.

Resulting planar network is after striking out container according to the present invention, its irregular deformation zone just can obtain regular coordinate grid pattern, thereby can make the pattern of required printing and literal on the regular coordinate grid of can facade and in the planar network, find out the distortion plate-making that correspondence position carries out image and literal easily, thereby obtain the distortion pattern galley that accurately to reduce, print again, strike out and have the distortion deep-draw color printing container of accurately going back original pattern, thus, make deep-draw color printing container by the method for making of any deep-draw color printing container of the present invention and can design the pattern of required accurate setting on the moulding of its container and the container irregular deformation zone and the moulding and the position arrangement of literal as required arbitrarily, be particularly suitable for food, candy, the making of metal color printing packing containers such as toy, thereby obtain colourful deep-draw color printing container, it has very positive meaning to the development of deep-draw color printing container.
