Description
Technical field
The present invention relates to offset lithography technical fields, and in particular to a kind of part oils method.
Background technique
During packaging material printing, in order to increase the brightness and surface protection of pattern, often need to print in ink
After oil.Packaging material such as packing box need to be pasted into box in post production process, and the surface after oiling is unfavorable for
It pastes, so being left white during oiling during oiling early period it is necessary to consider the needs of process after printing, that is, carries out
Part oils.
For convenience of the content for descending a piece herein is understood, lower offset lithography technique is first introduced.Fig. 1 is the principle of offset lithography technique
Schematic diagram.Offset lithography is a kind of current mainstream printing technology, as shown in Figure 1, printing plate rolls up the blanket on plate cylinder 1
On blanket cylinder 2, stock 4 is sandwiched between blanket cylinder 2 and impression cylinder 3 volume, is transferred pattern to using plate cylinder 1
On blanket on blanket cylinder 2, the squeezing action between blanket cylinder and impression cylinder is then recycled, it will be on blanket
Pattern is transferred on the stock.
It oils for part, there are mainly two types of the methods that printing industry uses:
One, hollow out blanket.The pattern of reserved white region is transferred on the blanket of rubber covered rollers using plate cylinder,
Then according to pattern-cut blanket.This method is at high cost, and time-consuming.It is 800 yuan or more that blanket one, which opens market price, Er Qieyi
It opens blanket and is simply possible to use in a typesetting order, cutting blanket primary time-consuming probably 2-3 hours, be delayed production.
Two, the resin plate that production part oils.According to the local area requirement that oils, the resin plate of convex-concave structure is made,
Then it replaces the rubber yardage roll on blanket cylinder on blanket cylinder with resin plate, is realized using the resin plate of this convex-concave structure
Part oils.The method is although simple and convenient, but the cost of every resin plate is at 3000 yuan or so, and a resin plate is also only
For a typesetting order, it is finished and is eliminated substantially, cost is higher.
Summary of the invention
It is very cheap technical problem to be solved by the invention is to provide a kind of cost and the part of production will not be delayed
Oil method, and the method for the present invention only needs lining paper on the inside of hollow out blanket to can be achieved with local oil.
Technical problem of the invention solves by following technical solution: a kind of side locally to be oiled using hollow out lining paper
Method, which is characterized in that its step are as follows: according to the lining paper on the inside of the blanket wound on reserved white region hollow out blanket cylinder,
Then the printing being transferred to the gloss oil on blanket using the squeezing action between blanket cylinder and impression cylinder between them
On object.
The present invention is made using the working principle of offset lithography by the lining paper below preparatory hollow out blanket specific region
Pressure lacks and cannot shift gloss oil when must correspond to the blanket and impression cylinder contact of lining paper hollowed out area, to realize part
It oils.
In the above method, according to the specific steps of the lining paper on the inside of reserved white region hollow out blanket cylinder blanket are as follows:
Step 1) forms big version according to lining paper specification layout, and represents reserved white region；
Step 2) determines the coordinate that white region is reserved in big version
Step 2-1) lateral coordinates, that is, X-coordinate starting point is scheduled on to the position for drawing regulation bit line to be 0；
Step 2-2) longitudinal coordinate, that is, Y-coordinate starting point is scheduled on seaming line position (picture position is followed in big version to become
It is dynamic)；
Step 3) corrects Y-coordinate
The Y-coordinate Y is corrected according to formula (1):
Revised Y-coordinate value y=original Y-coordinate value Y* deformation rate； (1)
Wherein, the deformation rate is calculated by formula (2):
Deformation rate=(blanket cylinder reference diameter-blanket thickness * 2)/blanket cylinder reference diameter； (2)
Step 4) adjusts the reserved white region in big version according to revised Y-coordinate value y；
Step 5) printing template mounting is cut on lining paper by cutting line (being made of the reserved white region after adjustment Y-coordinate).
The utility model has the advantages that tradition part oils method, it is difficult to overcome the problems, such as utilization hollow out lining paper at high cost, of the invention into
The method that row locally oils, by the lining paper on the inside of hollow out blanket, in reserved white region, because of blanket and impression cylinder contact
When pressure reduce and gloss oil cannot be shifted, thus realize part oil, the cost of lining paper is only at 1 yuan or so, so the present invention is big
The cost locally to oil is reduced greatly, and simple to operate, production will not be delayed.
Detailed description of the invention

Specific embodiment
With reference to the accompanying drawing and specific embodiment present invention is further described in detail.
The present embodiment is as follows using the method process that hollow out lining paper is locally oiled:
Step 1) is as shown in Fig. 2, form big version according to lining paper specification layout, and box ɑ indicates lining paper sideline in figure, and ɑ 1 is indicated
The domain of carton, big version includes the domain ɑ 1 of 4 cartons in Fig. 2, and ɑ 2 indicates reserved white region, then issues big version PDF and set
It is (processing is convenient) to be processed to enter AI (abbreviation of Adobe Illustrator) software.
Step 2) determines the coordinate that white region ɑ 2 is reserved in big version:
Step 2-1) lateral coordinates, that is, X-coordinate starting point is scheduled on to the position for drawing regulation bit line to be 0, i.e. lining paper is left in Fig. 2
Edge positions；
Step 2-2) longitudinal coordinate, that is, Y-coordinate starting point is scheduled on 3 position seaming line ɑ, as four Y measured in Fig. 2 are sat
Mark y1, y2, y3, y4.
Step 3) is modified Y-coordinate.
As shown in figure 3, the length y of lining paper 22 is less than the length of blanket 21 when coating equal angular on blanket cylinder 2
Y is spent, so size of the pre- hollowed out area apart from seaming side and reserved white region corresponding on normal printed matter are to stinging on lining paper 22
The distance on mouthful side be it is not reciprocity, the former is less than the latter.But for same type printing machine, their ratio
It is fixed and invariable, it may be assumed that
Deformation rate=y/Y=(blanket cylinder reference diameter-blanket thickness * 2)/blanket cylinder reference diameter, formula
The middle unit used is mm.
By taking Heidelberg, Germany Heidelberg CD102 printing machine as an example:
The machine blanket cylinder gear reference diameter is 270mm, to use the blanket of 1.95mm thickness to calculate,
Y/Y=(270-1.95*2)/270=266.1/270=98.55%, i.e. deformation rate are 98.55%.It is deformed with this
Rate corrects coordinate y1, y2, y3, y4, obtains coordinate y1', y2', y3', y4'.
Step 4) adjusts the reserved white region in big version according to modified Y-coordinate value；If seaming line ɑ 3 arrives lining paper in big version
The distance of hemline is not inconsistent with practical length of action, adjusts the position of figure in the ɑ of lining paper sideline, makes seaming line ɑ 3 to lining paper bottom edge
The distance of line is just equal to the practical length of action of lining paper.In Fig. 2, the distance of seaming line ɑ 3 to lining paper hemline is 10mm,
But when lining paper is on blanket cylinder, practical length of action is 19.72mm (every machine may be different), so needing will figure
Shape integrally moves up 9.72mm.
Step 5) printing template mounting is cut on lining paper by cutting line.
The machine parameter and working performance printed according to every, selects corresponding lining paper thickness.General printing machine uses 0.5mm
Thick art post paperboard (using the art post paperboard of 400 grammes per square metres) is good rear straight by lining paper hollow out according to the hollow out position drafted as lining paper
It connects and is mounted under blanket
The partial structure diagram of Fig. 4,5 printing machines locally to be oiled for the present invention using hollow out lining paper, are used for body
The existing present invention realizes that the principle locally to oil, the structure of printing machine other parts are not improved.As shown in figure 4, the printing machine packet
The blanket cylinder 2 and impression cylinder 3 being in contact are included, as shown in figure 5, blanket 21 is wrapped around on blanket cylinder 2, in blanket 21
Side is also wrapped around the lining paper 22 as printing cylinder-packing, and basis reserves white region and is formed with hollowed out area 221 on lining paper 22.
