Description
Technical field
The present invention relates to a kind of method that preferably in cold-foil stamping process, makes paper tinsel band beatization, in cold-foil stamping process, the paper tinsel band moves through according to the characteristics of motion and shifts the gap.Said transfer gap is described at least temporary transient deviation that be synchronized with the movement of paper tinsel band with respect to transfer cylinder at this through transfer cylinder with to the characteristics of motion of pressure roller formation and said paper tinsel band.At this, paper tinsel brings to few quilt and temporarily brakes, thereby can save foil material.In addition, the invention still further relates to a kind of being used for transfer layer is delivered to the device on the printable fabric from transfer foil, wherein this device comprises through transfer cylinder and transfer gap and transfer foil that pressure roller is formed and can pass said transfer gap by means of director element.In addition, in shifting the gap, be provided with the beat element that makes the paper tinsel beatization in order to save paper tinsel.In addition, the invention still further relates to a kind of printing machine, device of the present invention is provided in this printing machine, also relate to a kind of computer program, said computer program can be carried out corresponding method.In addition, the invention still further relates to a kind of data medium that is used to store the corresponding computer programs product.
Background technology
The paper tinsel of said type transmits equipment and in the finishing of print product, uses, for example so that produce gloss effect.This machine can be divided into hot paper tinsel marking press and cold-foil stamping machine.Under the situation of cold-foil stamping machine, transfer layer promptly passes to printable fabric such as page or leaf is opened only under pressure but additionally under heat effect, do not pass to flat material.Usually; Cold paper tinsel transmission equipment having the printing equipment that is bearing in the transfer equipment front is in the cold-foil stamping device; Jointing material in the printing thus, keeps the printed images that is made up of jointing material on page or leaf is opened; This printed images can be taken corresponding transfer layer off from employed transfer foil in paper tinsel transfer device inside, makes this ground, transfer layer zone open attached to page or leaf thus.At this, transfer layer can be delivered in the zone that is loaded with adhesive in shifting the gap under pressure basically partly.
Problem is in this paper tinsel transmission technology, and transfer foil must will be transferred layer with the zonule on speeds identical with printable fabric and the common only printable fabric and cover when transmitting.Especially participate in forming the transfer cylinder that shifts the gap and have a so-called passage usually, printing cloth can be fixed in this passage.In the zone of this passage, can not transmit transfer layer by means of printing.Therefore should regulate so all the time as far as possible, make when passage can not be in the zone of printable fabric printable fabric enter into transfer cylinder and the transfer gap between the pressure roller.Transfer foil is not have transfer layer will transfer to the zone on the printable fabric without other zone that is transferred through shifting the gap with utilizing.
In order to utilize transfer foil better and in order to reduce consumptive material; For example propose according to EP 932501B1; Make the transfer foil motion through a pair of dancer roll; These dancer rolls periodically move with the identical beat of the passage ground of transfer cylinder, and thus, it for example is zero speed that transfer foil is braked in the zone of passage.For this reason, two dancer rolls are coupled so each other, make the transfer foil band that stored by first trip gear of front portion from the deposit volume of still motion discharged simultaneously to collecting volume by second trip gear at rear portion.In this way can be and collect and guarantee the certain constant of band tensile force in the zone of volume at deposit volume.For this reason, in order to practice thrift transfer foil, two trip gear coupling ground move on braking direction.Paper tinsel especially also can be pulled from shifting the gap at this.
Can be that in this method problem that is used for saving paper tinsel foil tension can change, this particularly when be provided with in the zone at transfer cylinder for example be used to clamp blanket and/or be used to make to pressure roller hold the passage that tooth sinks in the month the time said problem can appear.So within a circle of transfer cylinder, transfer foil contacts at least once with the gap initial part, when contact, foil tension at first descends and then contacts with said gap initial part, and there, foil tension rises through unexpected pulling force strongly.Foil tension for fear of this fluctuation; In DE 102009020106A1, propose; Make the trip gear motion so asymmetricly against each other of hopping system, the feasible tension change of resisting transfer foil through trip gear corresponding reverse relative motion to each other.At this, avoid quoting this DE 102009020106A1 clearly with the beat method under the situation of tension force for the structure of principle ground description hopping system and in order to be described in.
Proposing in the disclosed prior art up to now, through realize the greatest savings of transfer foil toward the said paper tinsel of pulling back.On the contrary, if said paper tinsel only is braked or only retracted with little value,, can not realize greatest savings though then can cause saving.
Only disclose the characteristics of motion that is used for transfer foil by known prior art, the said characteristics of motion is described the motion of paper tinsel frigidly according to certain functions.If but the user of service expects to change the characteristics of motion of transfer foil, then this is fully impossible or can only expends and/or can only realize limitedly with high, because particularly must fully recomputate the characteristics of motion.
Summary of the invention
Task of the present invention is, advises a kind of method that is used to make paper tinsel band beatization, and the characteristics of motion is set up in its permission more simply, can make the said characteristics of motion adapt to boundary condition predetermined, that change in case of necessity sooner and in case of necessity simply thus.
In addition, task of the present invention also relates to a kind of equipment that is used to implement said method, a kind ofly has the printing machine of this equipment, a kind of computer program and an a kind of data medium that is used for the storing said program product that is used to implement said method.
Said task of the present invention is through the method solution of type according to claim 1.
Propose, said characteristics of motion section ground is set up by the section of elementary function for this reason.Generally be interpreted as such function for elementary function: it can be represented through analytical expression.What belong to this has: rational function, trigonometric function and inverse function thereof, exponential sum logarithmic function, hyperbolic functions and inverse function thereof and those can be used as and, poor, long-pending or merchant expresses the function of said function.
Particularly preferably be at this and should use this simple elementary function, for example trigonometric function, particularly cosine and SIN function and e function or its long-pending or and.
SIN function provides a characteristics of motion---thereby what this characteristics of motion provided transfer foil retracts and provides potential greatest savings fully; And exactly can make the said characteristics of motion adapt to predetermined value through set up movement function by said section (promptly not being) by single complete elementary function section, said predetermined value can not allow predetermined greatest savings just simply.
The said section of said elementary function must in its corresponding contact point (point of contact), have identical slope for this reason and in following zone, describe basically transfer cylinder speed---said zone abuts against in the synchronous operation with respect to transfer cylinder.Only in this way just can avoid transfer foil tension force tension change or it is limited on the minimum of a value to the major general.
Situation for during shifting corresponding to cold paper tinsel advantageously proposes, the said section of said elementary function its generally (in summation) on a part of the one-period of transfer cylinder, extend.What describe is such zone to the one-period of transfer cylinder at printing machine inner (if its for example relate to be blanket cylinder): in this zone, multiple or single printed images is delivered on the printable fabric.If transfer foil is passed on the printable fabric in printing machine inside, the blanket cylinder synchronous operation that then exists in case of necessity in the different inking devices of transfer cylinder and printing machine.Within this cycle of said transfer cylinder, then cause following zone or section: in said zone or section, do not have transfer layer to be delivered on the printable fabric from transfer foil.If transfer cylinder has the passage area that for example is used to clamp blanket, then this passage area is not used to transmit transfer layer at least.So the initial part description printing end of said passage area and the end portion of said passage area describe an other printing and begin, and particularly also are for the transmission of transfer layer.Therefore, according to the present invention, the size of said part (section of said elementary function is extending on this part at it generally) is less than or equal to such section---and in this section, there is not transfer layer to be passed on the printable fabric.The size of preferred said part also can particularly be regulated during the transfer method carrying out through operating personnel.Through being used to set up the elementary function of the said characteristics of motion; For said equipment, can easily regulate the control device of beat element of control device or the transfer foil of transfer foil like this, make to allow beat on the size of the new adjusting that carries out the transition to said part during the continuous service.
Preferred especially a selection of said elementary function is a symmetric function.Section through symmetric function particularly can be set up braking and acceleration distance in a similar fashion symmetrically within the said characteristics of motion.This particularly is applicable to SIN function or cosine function.General select such symmetric function, its initial part slope and end portion slope are basically corresponding to the synchronous operation of transfer foil and transfer cylinder.Under the situation of standardized amplitude, just be automatically to obtain said slope under the situation at standardized amplitude in the reflection on the angle of angle at transfer foil under 1 the situation for sine and cosine at transfer cylinder at slope.So for function f (x)=Asin (bx), must guarantee A=1/b, this in the contact point zone of said function with zone with respect to the synchronous operation adjacency of transfer cylinder in obtain slope and equal 1.
When advantageously always being to use the different section of same elementary function, always obtain the characteristics of motion towards the saving of difference expectation or the simple especially controllability of said portion size on the one-period at transfer cylinder; Wherein, Said elementary function is the elementary function that on the entire portion in the said cycle of said transfer cylinder, extends, and on said part, does not have transfer layer to be transmitted.At this, can advantageously relate to such SIN function or cosine function just, the zero crossing of its complete cycle overlaps with the initial part and the end portion of the said part in the said cycle of transfer cylinder.
For swimmingly from the synchronous operation that is used for beatization and from allow first first beat saved regulate to allow second second beat saved regulate and/or from the first in said cycle of transfer cylinder to the second portion transition; Propose in a further scheme of the present invention according to the present invention; Make the frequency adaptation of each section of said elementary function, thereby make the section after adaptive like this extend on the said part in said cycle of said transfer cylinder again generally at it with respect to them.So the amplitude of the section after adaptive like this by standardization in this wise, makes slope local that beginning portion and the end portion of said part locate corresponding to the synchronous operation of paper tinsel band with respect to transfer cylinder in another method step.But in this preferred especially part of using the mirror image identical with respect to the zero crossing of said elementary function, thus make operation on the section can identical ground, be applied on another section of said elementary function in case of necessity and thus with respect to automatically satisfying predetermined ratio with the neighboring region of synchronous operation adjacency and with respect to the contact point of this single section with having the symbol put upside down.
In known prior art, confirm the potential saving of the beat of transfer foil in advance.For the change of during printing, carrying out (this for example possibly be exactly this situation under digital printed situation) can not along with the change of saving in real time or along with the change with respect to the said part of the one-period of transfer cylinder is made a response.If the user finds not reach through machine the result of expectation, the user can not change saving.
Because the saving of the expectation of paper tinsel band is predetermined through the user and the length of respective section is confirmed according to the saving of expectation; Therefore obtain following possibility of the present invention for the user: promptly, within the said beat mass defect is being made a response or particularly under the situation of use digital print methods shown, making a response for the non-printing zone that changes.Particularly under the situation of digital print methods shown, can automatically discern through control device: the zone that should not be transferred be how to change and automatically recomputate the length of respective section according to the saving of expectation in this way and confirm the said section of said elementary function in real time again and coordinate mutually with the change of digital printed original copy.Can under the situation that the printed original in the digital printed device changes, realize beatization in this way, change at the one-period of part described in the said digital printed device with respect to transfer cylinder.This is adaptive particularly can immediately to carry out.
The angular speed of variation of the section that on an adjustable part of the one-period of transfer cylinder, extends and/or said transfer cylinder that equally well also can confirm said elementary function is as the basis of the respective section that is used for confirming said elementary function, and said elementary function is set up the said characteristics of motion.Even in this way can under the situation that printing environment changes, particularly in real time, realize beatization very flexibly in the printing operation that just continuing.
In a word, according to the present invention, the characteristics of motion can adapt to parameter change simply, maybe needn't use interpolating method and needn't store curve.Said to fit in this be not intensive calculations, thereby make in service being performed that it also can continue simply.
Equipment for like the said type of claim 8 also proposes independent protection; Said equipment is provided with the control device of beat element; Said control device is controlled said beat element in this wise, the feasible characteristics of motion of setting up said transfer foil according to method recited above.The control device of said beat element preferably should be connected and especially preferably have the input element of the predetermined value that is used to import following amount (saving of expectation, the section of elementary function are generally with respect to the share of the one-period of transfer cylinder and the angular speed of transfer cylinder) with the control device of printing machine at this.
In addition, for the printing machine that comprises a kind of related device and for a kind of computer program that method of the present invention is implemented on computers and for a kind of data medium of storing said corresponding computer program product independent protection is proposed.

Fig. 3 a-d) be the structure of the characteristics of motion of transfer foil,
Fig. 4 is the characteristics of motion of transfer foil under the greatest savings situation,
Fig. 5 is the characteristics of motion of the transfer foil that under 50% saving situation, draws.
The specific embodiment
A paper tinsel transfer device 1 has been shown in Fig. 1, and in this paper tinsel transfer device, transfer foil 2 is directed passing transfer gap 3.
Shifting gap 3 forms through transfer cylinder 5 with to pressure roller 4.Transfer foil 2 draws towards the direction that shifts gap 3 from 7 debatchings of deposit volume and by the drawing device 9 of a front portion.Deposit volume 7 herein in one on this unshowned friction mandrel and by with a speed drive littler than the speed of printable fabric 21.The driving of deposit volume 7 is carried out through friction mandrel.Transfer foil 2 is pulled out from deposit volume 7 through the drawing device 9 of front portion, and wherein, the roller of anterior drawing device 9 is driven with the fast speed than the friction mandrel of deposit volume 7.But anterior drawing device 9 is all the time with a speed operation littler than the speed of printable fabric 21.
The transfer foil 2 of debatching is guided through shifting gap 3 through the trip gear 13 of the front portion of beat module 11 and through the other roller 6 that turns to like this, makes transfer foil and transfer cylinder 5 form a winding angle α.Shifting 3 back, gap; Transfer foil 2 continues through turning to roller 6 to guide and be supplied to the trip gear 12 at rear portion; The trip gear at this rear portion turns to transfer foil 2 and it is supplied to the drawing device 10 at rear portion, and the drawing device at this rear portion is faster than the drawing device 9 of front portion.Drawing device 10 through the rear portion is directed to paper tinsel 2 on the collection volume 8.Collect volume 8 and also be bearing on the friction mandrel, this friction mandrel is driven than the drawing device at rear portion more quickly.At least this friction mandrel is driven like this, feasible speed of collecting the peripheral speed of volume 8 greater than the drawing device 10 at rear portion.Between friction mandrel and real collection volume 8, produce in this way and trackslip.Kindred circumstances also is applicable to deposit volume 7.
Transfer cylinder 5 has printing cloth, and this printing cloth is not shown specifically at this, and this printing cloth is tightened through a passage 20, and wherein, passage 20 also is set for the possible tooth of holding in the month that can receive pressure roller 4 sides.
Shift in the gap 3 if the preceding seamed edge of passage 20 113 arrives, then the band tensile force between trip gear 13 and the transfer gap 3 disappears.During transfer layer was passed to printable fabric 21, the summation of the speed of the trip gear 13 of the speed of anterior drawing device 9 and front portion obtained the speed of printable fabric 21.For this reason, trip gear 13 is along moving on acceleration direction 18 through the path of double-head arrow 16 marks.Preceding seamed edge 113 through passage 20 with pressure roller 4 is contacted the anterior trip gear 13 and trip gear 12 decoupling zeros at rear portion.Can not transfer layer be passed to printable fabric at preceding seamed edge and the trailing edge 113, intra-zone between 114.Therefore seamed edge 113 characterizes basically that printing finishes and the trailing edge 114 characterizes printing and begins before said, begins and can transmit transfer layer from this printing.Now, in said zone of not transmitting transfer layer (this zone is corresponding to the part of the one-period of transfer cylinder 5) save transfer foil 2, make transfer foil 2 braking at least in this zone.Look the saving of expectation and decide, this can only on pull direction 23, drive paper tinsel 2 lentamente, make it to stop or against before pull direction 23 pull back towards braking direction 24.For this reason, look the saving of expectation and decide, control device 22 correspondingly acts on the motor 14,15 of trip gear 12 and 13.Look the saving of expectation and decide, trip gear 12 and 13 is with the direction motion of little acceleration towards braking direction 19, thereby can make transfer foil 2 static or pulled back.
For and make transfer foil 2 with respect to transfer cylinder 5 synchronous operations, transfer foil 2 is quickened.At this constantly, transfer cylinder 5, transfer foil 2 with pressure roller 4 or printable fabric 21 are formed common contact and the acceleration of transfer foil 2 is practically impossible again under the situation that continues contact.For this reason; Control the motor 14,15 of trip gear 12,13 in this wise by means of control device 22; Make paper tinsel 2 quicken along acceleration direction 18 again through the motion of trip gear 12,13, thus make transfer foil 2 final again the latest at the channel end place, just at the trailing edge 114 places or printing begin to locate to have the speed along pull direction 23 substantially the same with transfer cylinder 5.
Fig. 2 shows a part of paper tinsel transfer equipment 100.Such paper tinsel transfer equipment 100 can be installed in printing machine 115 inside.Page or leaf is opened 21 and is transferred through bringing device 101 and passes printing gap 109, and this bringing device is the traditional printing device of printing machine 115.In this printing gap 109, printable fabric 21 is loaded adhesive partly.Page or leaf is opened 21 and is continued then to be transferred and pass paper tinsel transfer device 1.As said, page or leaf is opened 21 and is directed passing and shifts gap 3, shifts in gap at this, and this page opened in the zone that itself is loaded adhesive the transfer layer that takes off transfer foil 2 from transfer foil 2.
Opening 2 through the page or leaf of handling like this can continue to be transferred to pass printing machine then; Promptly pass the paper tinsel transfer equipment; Thus; This page or leaf is opened and is moved to another back to back printing equipment 103, and this back to back printing equipment also has a printing gap 109, and this printing gap forms by blanket cylinder 110 with to pressure roller 111.In addition, printing equipment 103 also has an inking device 112.Available traditional approach is opened 21 to the page or leaf that is loaded with transfer layer and is carried out chromatography in printing equipment 103 then.
Fig. 3 illustrates the flow process of the characteristics of motion that is used to design transfer foil 2.For this reason, in a coordinate system, shifting the pull in the gap 3 along pull direction 23 in the angle
of the corner of record transfer cylinder 5 on the X axle and at record transfer foil 2 on the Y axle.In order to describe vividerly, said pull provides with angular coordinate ω at this.That is to say, show the motion of the motion of transfer foil 2 with respect to transfer cylinder 5.
That illustrate is a part 2 π-K of whole cycles 2 π of transfer cylinder 5.Said part 2 π-K describes passage 20, and in said passage, transfer foil 2 can be accelerated and/or brake.For this reason, be defined in the zero point of said coordinate system on the position of transfer foil 2 at beginning portion place of passage 20.Parameter K is described the trailing edge 114 of passage 20 and the printable area between the preceding seamed edge 113.Negative second dervative
Be meant: transfer foil 2 is braked with respect to transfer cylinder 5, this since transfer cylinder 5 at ω
T=1 draw
Even motion afterwards for
Also mean temporal braking.Similarly, also be like this for positive second dervative
.
As elementary function, what it will be described is the greatest savings of transfer foil 2 in passage 20 at SIN function 301 shown in Fig. 3 a.
Generally set up SIN function according to formula 1:
The slope of said SIN function draws according to formula 2:
For low-angle, just in the zone of zero point or zero crossing, the slope of common SIN function is described through constant A b.This is for example drawn by the Taylor expansion of SIN function.
Therefore, through confirm constant A and b can be with employed SIN function always with simple mode and method in synchronous operation, just be adapted to the slope of the equation of motion of transfer foil 2 when value＜0 and＞2 π-K.Under the situation of employed here expression way
, an angle is through an angle mapping.In synchronous operation, transfer foil 2 that is to say with the speeds identical with transfer cylinder 5, obtains passing the straight line with slope 1 at zero point here in the employed expression way of said synchronous operation.That is, the condition of contact of said SIN function 301 satisfies through following requirement under the situation of zero crossing:
(3)A＝1/b。
Said requirement is satisfied through A=b=1 with the simplest mode.
According to the method for advising here, said SIN function 301 should have a complete cycle in the said part 2 π-K inside in the said cycle of transfer cylinder 5.Said value K describes the length of said printable area at this.Obtain the value of the constant in the formula 1 thus, according to according to formula 4:
(4): Asinb (2 π-K)=0 obtain
Then also automatically by the predetermined value of said printable area or conversely the channel width through passage 20 obtain A according to formula (3).
According to Fig. 3 b to 3d, set up the characteristics of motion by the section 302,303 of the SIN function among Fig. 3 a 301 then, the said characteristics of motion is described the saving of transfer foil 2, and said saving is less than the maximum within the said part 2 π-K in the passage 20.
For this reason, select said section 302 and 303 in this wise, make and under the situation of sinusoidal (π), cut off symmetrical section 304,305 at breakpoint 306,307 towards zero crossing N respectively respectively from SIN function 301.Look potential greatest savings expectation percentage and obtain the width of said section 305,304 surely.The saving target of expectation is using simple elementary function for example to confirm under the situation of SIN function 301 or using under the situation of different elementary functions and confirming in case of necessity digitally in these computational methods that can know by one of skill in the art.
According to Fig. 3 a, downcut in this wise from the said SIN function 301 or remove section 304,305, make to form breakpoint 306,307.According to Fig. 3 b, with first section 302,303 of said SIN function 301 along the direction of arrow 308,309 so symmetrically towards stretching each other, make said breakpoint 306,307 and said zero point N be in a straight line.The function of such formation of first section 303 on the right of making then moves up to degree on the direction of displacement vector 310 like this, makes breakpoint 306 run on the breakpoint 307.In this point shown in Fig. 3 c.In addition, with first section 302 that draws like this ' with 303 ' fit each other in this wise, make slope distinguish=1 with 2 π-K place at corresponding point 0.Considering under the situation of a saving to obtain the change curve of in Fig. 3 d, describing of the characteristics of motion for transfer foil 2 with respect to this transfer foil 2 and the synchronous operation of transfer cylinder 4 in this way, said saving is less than the saving of the maximum possible in the printable area in the passage 20 or not.
Need be pointed out that once more; Transfer foil 2 is in printable area not, for example the greatest savings in passage 20 means: transfer foil 2 is in again on the identical point at the place, end that saves distance 2 π-K with respect to the position of the displacement of transfer cylinder, and it is in the place that begins that saves distance 0 on said point.This guarantees through SIN function 301, is in two points because be used for the zero crossing of the position of transfer foil 2.
Fig. 4 is illustrated in the characteristics of motion of transfer foil 2 under the situation of greatest savings.
For the purpose of clearer, one-period 2 π of transfer cylinder 5 represent through standardized angle
at this.Equally, represent the motion of transfer foil 2 and transfer cylinder 5 through standardized angle
.The distance that transfer cylinder 5 is passed by in one-period is at this in standardized angular coordinate
The characteristics of motion of transfer cylinder 5 is described through the straight line 401 with slope 1 at this.
Cycle of transfer cylinder this illustrate 5 50% as possible saving distance.This draws through the beatization that the printing under 0.2 situation finishes in the imprintable zone between the beginning of the printing again DA under DE and 0.7 situation for the one-period of transfer cylinder respectively.In 0 to 0.2 zone, transfer foil 2 and the operation of transfer cylinder 5 parallel synchronous ground.This is through the movement function F of transfer foil 2
F Linear segment 402 between point 0 and 0.2 is described.
The beatization of transfer foil 2 draws in the following manner: promptly, said transfer foil finishes DE from the printing under the situation of
and on the direction of braking direction 24, is braked according to the SIN function 301 shown in Fig. 3 a.In order to carry out practical application, said SIN function 301 also must for example be this means to replace 2 π with 1 respectively by standardization itself.301 description of the sine function starts with the printing end of the printing (DE and DA), between which is
and
region between a full cycle.The saving section 403 of said paper tinsel movement function FF finishes DE through said printing and forms with printing beginning DA; It is just corresponding to said SIN function 301; Wherein, As describing, this SIN function 301 begins the place in the said cycle, just under the situation of
and at said end cycle place, just the slope under the situation of
is respectively corresponding to the slope of straight line 401.Begin DA from said printing; Paper tinsel movement function FF constitutes through a linear segment 404 again; Thereby make this paper tinsel 2 now again with said transfer cylinder 5 synchronous operations, that is to say that said linear segment 404 has been described one and has been parallel to the straight line that said straight line 401 extends.Normalized angular coordinates
in the journey (the transfer roller 5 end of the cycle in
in the case of the distance traveled) and
case away (transfer foil 2 at the end of the period of the transfer roller 5 pm in
in the case of the distance traveled ) transfer foil 2 gives the difference in the transfer roller 5 within one cycle of savings and by differential
to describe.
Obtain
under its situation shown in here
This is corresponding to the possible saving scope between DE and the DA under 0.5 the situation of the one-period of transfer cylinder 5.This is the saving of the maximum possible of transfer foil 2.
In the
time through 0:00 and in the
when passing through point
and
description of the transfer foil 2 is a straight line in the transfer gap 3, the average movement.The slope of said straight line 405 is corresponding to drawing velocity, and transfer foil 2 is left behind from deposit volume 7 with said drawing velocity through the drawing device 9 of front portion.
Fig. 5 illustrates the movement function FF of paper tinsel, utilizes said movement function to realize the saving half the approximately with respect to greatest savings.Here; The section 302,303 of SIN function 301 finishes combination as shown in Fig. 3 a-3d in the saving zone between DE and the printing beginning DA in printing; Thereby make next forwardly to obtain a linear segment 402 and in Background Region, obtain a linear segment 404 in the zone that this linear segment is connected saving section 403 back as the paper tinsel movement function FF of the characteristics of motion that is used for paper tinsel band 2.The section 302,303 of said SIN function 301 particularly can be selected at this like this, makes invocation point
under the situation of
, provide the saving
of expectation
Can confirm to be used for the section 302,303 of paper tinsel movement function FF in this way according to the predetermined value of
adaptedly.Because the continuous transition of paper tinsel movement function FF is even not only finish DE and print the change that all during cold paper tinsel module or cold paper tinsel transfer device 1 continuous service, easily realizes the saving
of expectation in the zone that begins DA in the zone of breakpoint 306,307 but also in printing.This particularly is suitable for for the situation of using SIN function 301, thereby because said section 302,303 can be confirmed with the simplest mode and calculate and can confirmed and used by simple computer real-time ground (on the fly).
