Abstract
The invention discloses a generating method and a generating system of trapping areas, which belong to the technical field of trapping in package printing. An existing generating method of the trapping areas is low in efficiency and bad in effect. The generating method and the generating system comprise the following procedures: firstly obtaining trapping borders of an object to be trapped and recording the adjacent relationships of the trapping borders; then judging and recording the trapping direction of each trapping border; connecting the trapping borders from each trapping border Lx along one direction and skipping the connected trapping border until the connection is finished; and connecting the trapping borders from each trapping border Lx along another direction and skipping the connected trapping border until the connection is finished. The connection condition is that judging whether two adjacent trapping borders can form one-to-many or many-to-one connection according to the trapping direction; if yes, then connecting the two trapping borders; and if no, then disconnecting the two trapping borders. The one-to-many connection is prior to the many-to-one connection. Finally, the trapping areas are formed. The generating method and the generating system of the trapping areas improve the generating efficiency and trapping quality of the trapping areas.

Describe the present invention below in conjunction with embodiment and accompanying drawing.
Fig. 1 shows the structure of the said area of trap generation system of this execution mode.As shown in Figure 1, this system comprises deriving means 11, the tape deck 12 that is connected with deriving means 11, the judgment means 13 that is connected with tape deck 12, the jockey 14 that is connected with judgment means and the generating apparatus 15 that is connected with jockey 14.
Deriving means 11 is used to obtain the sunken seal border of waiting to fall into the seal object, is respectively L
1, L
2..., L
n, wherein, n is a positive integer.Said sunken seal border is meant waits to fall into the public boundary that needs to fall into seal in the seal object between the color lump.
Judgment means 13 be used to judge and write down every sunken India side that falls into the seal border to.If fall into the seal border is that gradual change falls into the seal border, then judgment means 13 be used to judge and write down gradual change fall into the sunken India side that prints two end points in border to.
Jockey 14 is used to connect sunken seal border.It is following that jockey 14 connects the process that falls into the seal border:
A. take out and fall into seal border L
x, along a direction from L
xBeginning connects to fall into according to condition of contact prints the border, till can not connecting.Again along another direction from L
xBeginning connects to fall into according to condition of contact prints the border, till can not connecting.The initial value of x is 1.
Said condition of contact is: according to sunken India side to judging that adjacent two are fallen into the seal borders and whether can form one and advance multi-link or advance a connection more, in this way, then connect; As not, then do not connect; Said one advances multi-link having precedence over advances a connection more.Said one advances to be meant that same color lump falls into seal to the different color blocks around it more, advances one more and is meant that different color blocks falls into seal to same color lump.
B. make x=x+1, if x＞n then finishes to connect; Otherwise judge L
xWhether connect; In this way, then repeat this process; As otherwise go to process a.
If adjacent two are fallen into and to have one to be that gradual change falls into the seal border in the seal borders, then the jockey 14 sunken India side that falls into the seal border based on non-gradual change to fall into sunken India side that the adjacent gradual change in seal border falls into seal border end points to judging that adjacent two are fallen into and print borders and whether can form one and advance multi-link or advance one more to be connected with non-gradual change.
If adjacent two are fallen into the seal borders and are gradual change and fall into the seal border, then jockey 14 based on the sunken India side that falls into seal borderline phase neighboring terminal point to judging whether adjacent two sunken borders of printing can form one and advance multi-link or advance a connection more.
Generating apparatus 15 is used to generate area of trap; Wherein, the sunken seal border for having connected generates area of trap as a whole with it.
Fig. 2 shows the method flow that adopts system shown in Figure 1 to generate area of trap.As shown in Figure 2, this method may further comprise the steps:
(1) deriving means 11 obtains the sunken seal border of waiting to fall into the seal object, is respectively L

2..., L
n, n is a positive integer.Tape deck 12 records fall into the syntople between the seal border.
At first scanning is waited to fall into all color lumps in the seal object, obtains the public boundary of all adjacent color lumps.Judge then whether two color lumps under the public boundary satisfy the seal condition that falls into, if satisfy the seal condition that falls into, then this public boundary is for falling into the seal border.Have one to be the gradual change color lump if fall in two color lumps under the seal border, then should fall into the seal border is that gradual change falls into the seal border.Said gradual change color lump is meant the color lump that color gradually changes.
In this execution mode; Whether the color lump of judging the public boundary both sides satisfies the method for seal condition employing based on printing ink site percentage and brightness that fall into; The concrete implementation procedure of this method can be referring to one Chinese patent application (publication number: 101610343A; Open day: the record 2009.12.23), no longer detail here.
Treat that with shown in Figure 4 sunken seal object is an example.Wait to fall into the seal object and comprise color lump A, color lump B, color lump C and color lump D.Wherein, public boundary 1,2,3 and 4 is for falling into the seal border, and other public boundaries are non-sunken seal border.Wherein, falling into seal border 4 is color lump A other borders except that right side boundary.
(2) judgment means 13 judge and write down every sunken India side that falls into the seal border to.
Fall into India side to determination methods also can no longer detail referring to the above-mentioned patent application document of quoting as proof here.If fall into the seal border is that gradual change falls into the seal border, then judge and write down gradual change fall into the sunken India side that prints two end points in border to.The sunken India side that falls into seal border end points for gradual change to, can be through the ink percentage and brightness acquisition of judging the end points both sides.
In the above-mentioned instance, each bar falls into sunken India side arrow direction in like Fig. 4 on seal border.
(3) jockey 14 takes out and falls into seal border L
x, along a direction from L
xBeginning connects to fall into according to condition of contact prints the border, till can not connecting; Again along another direction from L
xBeginning connects to fall into according to condition of contact prints the border, till can not connecting.The initial value of x is 1.
The condition of contact that falls into the seal border is: according to sunken India side to judging that adjacent two are fallen into and print borders and whether can form one and advance multi-link or advance a connection more, in this way, then connection; As not, then do not connect; Said one advances multi-link having precedence over advances a connection more.
In this execution mode, the concrete method of attachment (connecting along certain direction) that falls into the seal border is as shown in Figure 3, may further comprise the steps:
1. with L
xAdjacent all fall in the seal border, judge whether to exist can with L
xForm one and advance multi-link sunken seal border L
y, skip on the sunken seal border that had connected; If exist, then go to step 2.; If do not exist, then go to step 3.;
2. connect L
xAnd L
y, make L
x=L
y, go to step 1.;
3. with L
xAdjacent all fall in the seal border, judge whether to exist can with L
xForm the sunken seal border L that advances a connection more
z, skip on the sunken seal border that had connected; If exist, then with L
xAdjacent all fall into and continue to judge L in the seal border
zWhether can fall into the seal border with him and form one and advance multi-linkly, skip on the sunken seal border that had connected; In this way, then go to step 5.; As not, then go to step 4.;
4. connect L
xWith L
z, make L
x=L
z, go to step 1.;
5. this direction connects end.
Wherein, y, z are positive integer and 1≤y, z≤n.
After a direction connects end, connect the sunken seal border of another direction again with same method.Because one is fallen into the seal border and has two end points; So connect from an end points along a direction earlier and fall into the seal border; Connect from another end points along another direction again and fall into the seal border, can fall into the sunken seal border that the seal border connects into a unification with many like this.
In the above-mentioned instance, at first judge and fall into seal border 1.Begin from the upper extreme point that falls into seal border 1, along a direction, with fall into seal border adjacent all of 1 upper extreme point fall into judge whether to exist in seal borders can with fall into seal border 1 and form one and enter multi-link sunken seal border.Since with fall into the seal adjacent sunken seal border of 1 upper extreme point, border the seal of falling into border 2 only arranged, and fall into seal border 1 and 2 and all fall into seal to color lump A, therefore fall into seal border 1 with sunken print border 2 can form advance more one be connected and can not form one advance multi-link.With fall into seal border adjacent all of 1 upper extreme point fall into continue to judge in seal borders other fall into seal borders can with fall into seal border 2 form one advance multi-link.Because with the sunken seal adjacent sunken seal border of 1 upper extreme point, border the seal of falling into border 2 is only arranged, therefore connection falls into seal border 1 and 2.
Judge then and fall into seal border 2.Since with fall into the sunken seal border that seal border 2 upper extreme points are connected the seal of falling into border 4 only arranged, only need therefore to judge that can fall into seal border 2 prints border 4 and form one and how advance or advance more one and be connected and get final product with falling into., fall into seal border 2 and 4 and can form to advance one more and be connected to can knowing according to sunken India side, and can not form one advance multi-link.Therefore need with fall into seal border adjacent all of 2 upper extreme points fall into continue to judge in seal borders other fall into seal borders can with fall into seal border 4 form one advance multi-link.Because with the sunken seal adjacent sunken seal border of 2 upper extreme points, border the seal of falling into border 4 is only arranged, therefore connection falls into seal border 2 and 4.
Judge again and fall into seal border 4.With fall into the sunken seal border that seal border 4 lower extreme points are connected the seal of falling into border 1 and 3 arranged, judge earlier fall into seal border 4 with sunken print border 1 can form one advance multi-link., fall into seal border 4 and 1 and can form to advance one more and be connected to can knowing according to sunken India side, and can not form one advance multi-link.Continue to judge fall into seal border 1 with sunken print sunken seal border 3 that border 4 lower extreme points are connected can form one advance multi-link., fall into seal border 1 and 3 and can form one and advance multi-linkly to can knowing according to sunken India side, therefore do not connect to fall into and print border 4 and 1.Judge to fall into seal border 4 and 3 then and can form one and advance many or advance one more to be connected, print border 4 and 3 and promptly can not form one and advance multi-link can not formation again and advance one more and be connected owing to fall into.Therefore falling into seal border 4 is not connected with 3 yet.So far this direction connects end.
Begin from the lower extreme point that falls into seal border 1, along another direction, with fall into seal border adjacent all of 1 lower extreme point fall into judge whether to exist in seal borders can with fall into seal border 1 and form one and enter multi-link sunken seal border.With fall into the seal adjacent sunken seal border of 1 lower extreme point, border the seal of falling into border 3 and 4 arranged judged on another direction owing to fall into seal border 4, not on this direction, only need therefore to judge that can fall into seal border 1 and 3 form one and how advance or advance one more to be connected., fall into seal border 1 and 3 and can form one and advance multi-linkly to can knowing according to sunken India side, therefore connect to fall into and print border 1 and 3.Judge the annexation on sunken seal border 3 again, be connected with sunken seal border 3 owing to falling into the seal border, so this direction connection finishes.
Final connection result is for falling into seal border 3 and fall into seal border 1 and is connected, falls into seal border 1 and fall into seal border 2 and is connected, falls into seal border 2 and be connected with the sunken border 4 of printing, and sunkenly prints the sunken seal border that border 3,1,2,4 has formed a unification.
In the method for attachment on above-mentioned sunken seal border, no matter begin to connect from any one any one direction that falls into the seal border, that finally obtain all is identical connection result, and the trapping effect of this connection is optimum.For example, if begin to connect from falling into seal border 3, can know according to the method described above that from falling into the left end point on seal border 3, along a direction, falling into seal border 3 can be connected with 1, falling into seal border 1 can be connected with 2, and falling into seal border 2 can be connected with 4; From falling into the right endpoint on seal border 3, along another direction, not falling into the seal border can be connected with 3.Connect the result and begin to connect identical from falling into seal border 1.If begin to connect from falling into seal border 2, in one direction, falling into seal border 2 can be connected with 4; On another direction, falling into seal border 2 can be connected with 1, and falling into seal border 1 can be connected with 3.Connect the result also with begin to connect identical from falling into seal border 1.
In the judgement that falls into seal border condition of contact; If adjacent two are fallen into and to have one to be that gradual change falls into the seal border in the seal borders, the sunken India side that then falls into the seal border according to non-gradual change to fall into sunken India side that the adjacent gradual change in seal border falls into seal border end points to judging that adjacent two are fallen into and print borders and whether can form one and advance multi-link or advance one more to be connected with non-gradual change.If adjacent two are fallen into the seal borders and are gradual change and fall into the seal border, then according to the sunken India side that falls into seal borderline phase neighboring terminal point to judging whether adjacent two sunken borders of printing can form one and advance multi-link or advance a connection more.
(4) make x=x+1, if x＞n then goes to step (5); Otherwise judge L
xWhether connect; In this way, then repeat this step; As otherwise go to step (3).
(5) generating apparatus 15 generates area of trap; Wherein, the sunken seal border for having connected generates area of trap as a whole with it.
