Embodiment
(1) utilize ink-jetting style to manufacture the manufacture method of color filter
The manufacture method of color filter of the present invention is to utilize ink-jetting style to manufacture the method for color filter, wherein, make that head unit that form scans on substrate on main scanning direction, arranging a plurality of by record-header, the ink land that make to spue from said nozzle are in the peristome of the unit that the black matrix (BM) by being formed on aforesaid substrate is divided, and above-mentioned record-header has the nozzle row of having arranged a plurality of nozzles on sub scanning direction.
Below, use accompanying drawing to be elaborated to an example of embodiments of the present invention.In addition, in the present example, show the manufacture method of the color filter formed by this three look of RGB, but the invention is not restricted to this example, and for example can also be applied to the manufacture method of the printed matter formed by yellow, magenta, blue-green, these four colors of black (YMCK).
Fig. 1 observes the skeleton diagram of the head unit consisted of three record-headers that carry side by side (1,2,3) from the nozzle direction.Spue the respectively ink of each color (order arbitrarily) of R, G, B of record-header 1,2,3.
The arrangement of the nozzle of each record-header can be both delegation shown in Figure 1, can be also multirow.In the situation that multirow, by each nozzle row is staggered in its orientation configuration, can reduce apparent nozzle interval, can print and write meticulousr pattern.
When substrate is applied to ink, make above-mentioned head unit towards direction of scanning X (main scanning direction) scanning (main sweep), and ink is spued on substrate.In this case, as shown in Figure 1, usually on sub scanning direction, arrange a plurality of nozzles of each record-header, on main scanning direction, arranged side by side each record-header that possesses this nozzle row.
As record-header, can use and can set respectively from the spue record-header of many ink droplets (multidrop) mode of discharge-amount of ink of each nozzle.With the head of such many ink droplets mode can change according to the position of land to the ink discharge-amount spued in peristome, and prevent colour mixture.
Fig. 2 is the skeleton diagram that is formed with the substrate of BM.Peristome by the regularly arranged unit of being divided by cancellate BM.Peristome to this unit applies the ink of each color and becomes sub-pixel.Generally, peristome presents rectangle roughly, to the peristome of arranging on this rectangular long side direction capable (row of the row of the row of peristome 1, peristome 2, peristome 3), applies respectively the ink of same color.In the situation that the color filter of three looks, peristome 1,2,3 respectively capable as R, G is capable, B capable (random order) become the unit repeatedly of a group.
As making head unit scanning shown in Figure 1, all peristomes on substrate are applied the means of the ink of regulation, make head unit from the end of substrate towards a direction (main scanning direction go journey) scanning (main sweep), while applies ink to the peristome on substrate, when arriving opposed end, make it on the direction with the direction of scanning quadrature (sub scanning direction), carry out the subscan of the length suitable with head width.Next, again make head unit carry out main sweep on the direction (backhaul) opposite with above-mentioned main scanning direction, the while applies ink to the peristome on substrate.
By repeatedly carrying out this action, even large-sized substrate also can use little head unit to apply ink to substrate integral body.In addition, even the substrate of various sizes also can apply ink to integral body without changing nozzle and manufacture color filter.
Direction (main scanning direction) as making head unit scanning, be preferably the short side direction that is formed on the peristome on substrate.Now, preferably so that the orientation of the nozzle row form configured head unit consistent with the long side direction of peristome.By such configured head unit and substrate, and set direction of scanning, can use efficiently nozzle, can improve productivity.
In the above description, enumerated fixing base and made the example of head unit scanning, but on the contrary, made substrate scanning and be also contained in the present invention by the method that fixing head unit applies ink.
(2) operation (a): the judgement operation of effective nozzle and invalid nozzle
In the present invention, when making head unit scanning and being applied to ink on substrate, make in advance and register for the seal of all nozzles in each record-header and write pattern (data are controlled in spuing of ink).
Can at first make the seal suitable with peristome and write pattern (indivedual pattern), and, by all nozzles of its application (insertions) in this head unit, make the seal of a head unit and write pattern (full seal is write pattern).Wherein, in the nozzle that forms each record-header, exist the nozzle of the position of falling peristome and the nozzle that non-land arrive the position of peristome.
Fig. 3 illustrates the position on ink land to a peristome that spues the nozzle row of a record-header is capable.As can be seen from Figure 3, in the situation that from all nozzles ink that spues, according to the position relationship of peristome and nozzle, as long as land are rightly arranged to the ink that spues in peristome, the ink that spues on the boundary line of falling peristome and BM or on BM is also just arranged.
But, make the ink land to the boundary line of peristome and BM or the phenomenon on BM becomes the reason of colour mixture, and wasted ink, so should avoid.Therefore, in the present invention, in advance for each above-mentioned record-header, for all nozzles, judge each nozzle be the land nozzle that arrives the position of peristome (effectively nozzle), or not land to the nozzle of the position of peristome that is land to the boundary line of peristome and BM or the nozzle of the position on BM (invalid nozzle), with not from the invalid nozzle ink that spues.
Namely, method of the present invention comprises that (judgement operation: operation (a)): the land of take in a plurality of nozzles in above-mentioned each record-header are effective nozzle to the nozzle of the position of peristome to following operation, the land not of take are invalid nozzle to the nozzle of the position of peristome, for each above-mentioned record-header, be effective nozzle or invalid nozzle for all nozzle judgements.
The concrete grammar of judgement is not particularly limited; But for example can, for the nozzle of the N on head, according to the width of BM, the length on opening minister limit, judge effective nozzle and invalid nozzle by following formula (1).
<formula 1 >
D＜(A×E)％(B+C)＜(B-D) (1)
Wherein, in following formula (1), " % " is the meaning of remainder number when carrying out division, and mark A～E means the following meaning.
A: nozzle sequence number (integer of 1～N)
B: the length on opening minister limit
The C:BM width
D: enough and to spare width
E: nozzle interval
In addition, when by following formula (1), judging effective nozzle and invalid nozzle, as prerequisite, need to make to mean the initial point, consistent with the initial point of the coordinate system of the length direction of the peristome of being divided by BM of coordinate system of the position of nozzle.A～E in following formula (1) is expressed as apart from the coordinate (distance) of initial point (coordinate system of the position of expression nozzle and the public initial point of the coordinate system of the length direction of the peristome of being divided by BM).
Below, use Fig. 4, to by following formula (1), judging that the method for effective nozzle and invalid nozzle describes.
Nozzle sequence number A in above-mentioned (1) is illustrated in a record-header with 1～N the nozzle that is arranged in delegation from an end, the nozzle sequence number during append serial numbers (note, the nozzle overlapped with initial point of take is No. 0) successively from this end.Therefore, " (A * E) " mean the position (apart from the distance of an end) of nozzle in record-header of (nozzle sequence number A) arbitrarily.In addition, " (B+C) " means by the black matrix on glass substrate (BM) and the length of a group of forming on this peristome long side direction in the peristome that this black matrix is divided.
Using from the beginning an end to the distance till the nozzle of nozzle sequence number A (remainder of A * E) obtain divided by (B+C) as from the nearest peristome end of distance initial point side to till the nozzle of nozzle sequence number A apart from F (F among Fig. 4) ((% (B+C)=F) of A * E).
For example, from the end Fig. 4 the nozzle 7 ' of the 14th (nozzle sequence number 14) from this initial point to this nozzle till the distance be (14 * E), in the situation that the example of Fig. 4, deduct the remainder of the distance twice of (B+C), namely (14 * E) remainder obtained is F (with reference to Fig. 4) divided by (B+C).
For make from the ink with drop width spued nozzle (nozzle sequence number A) arbitrarily be not applied on the boundary line of peristome and BM and reliably land in peristome, must make the length suitable with F in nozzle sequence number A be greater than 0 and be less than the length B (0<F<B) on opening minister limit.In the situation that F meets this condition, understand land in this peristome from the ink that spues of this nozzle.
But at this, because the drop that is applied to the ink on substrate has size, so even F does not meet above-mentioned condition " 0<F<B ", only the end by will be from the beginning rises to the distance till the nozzle of nozzle sequence number A and is made as (A * E), from the ink spued the nozzle of nozzle sequence number A, the situation on the boundary line of falling peristome and BM is also arranged.Therefore, as the drop width, in formula (1), need to consider " enough and to spare width D ".
If consider this enough and to spare width D, for make from the ink with drop width spued the nozzle of nozzle sequence number A be not applied on the boundary line of peristome and BM and reliably land in peristome, must make the F of nozzle sequence number A be greater than the enough and to spare width (D) of initial point side and be less than from the length on opening minister limit, deducting away from the enough and to spare width of a side of initial point and the value (B-D) obtained.Therefore, be used to making tighter condition that any nozzle becomes effective nozzle be " D<F<(B-D) ".Because F is that as above (% (the B+C)=F of A * E), so according to formula (1), effectively the condition of nozzle is " D<(% (B+C)<(B-D) of A * E) ".
For example, in the situation that F is less than or equal to D, the ink land with drop width that spue from the nozzle of nozzle sequence number A are directly over the end of the initial point side of peristome or on BM.In addition, for example, in the situation that F is more than or equal to (B-D), the ink land with drop width that spue from the nozzle of nozzle sequence number A are directly over the end of a side of the initial point that keeps away oral area or on BM.Therefore, which kind of situation no matter, the ink that spues all exceeds peristome ground land and can't in peristome, apply ink reliably, so the nozzle of this nozzle sequence number A can't be made as to effective nozzle.
Like this, in the situation that meet following formula (1), the nozzle land of nozzle sequence number A, to the appropriate position of peristome, are judged as effective nozzle.In the situation that do not meet following formula (1), be judged as invalid nozzle.So, by for nozzle sequence number 1～N, carrying out this judgement, can be effective nozzle or invalid nozzle for all nozzle judgements.
In following formula (1), can suitably select B, C, E according to the design size of head unit.In addition, D considers the size of drop of ink and definite value, so long as get final product with the measure-alike degree of actual ink droplet, be not particularly limited, but preferred from the scope of 20～50 μ m, selecting.
In addition, in the situation that the nozzle interval is regarded as is constant, can judge by following formula (1); If but in the situation that the deviation of the degree that on the nozzle interval, existence can't be allowed can print the landing positions of measuring exactly from the ink of each nozzle by examination, and for each nozzle effective nozzle of judgement and invalid nozzle.
(3) operation (b): indivedual design producing operations
In the present invention, when all nozzles making seals in each record-header are write pattern, the nozzle sets of each record-header is divided into to effective nozzle sets and invalid nozzle sets in following formula operation (a), and make and to spue for the ink to relevant to peristome that (operation (b): indivedual design producing operations), the effective nozzle sets that faces toward the position of falling a peristome is inserted this indivedual patterns to indivedual patterns of controlling.
As the ink suitable with peristome spue indivedual patterns of controlling data be determine to the ink discharge-amount of the nozzle number that enters a peristome, each nozzle and should impose on a peristome ink amount etc. and make.
In addition, to the effective nozzle that enters a peristome (indivedual patterns in effective nozzles) without the ink that all spues, in also can the effective nozzle in indivedual patterns, there is the nozzle (hereinafter referred to as " the non-nozzle that spues ") of the nozzle (hereinafter referred to as " nozzle spues ") of the actual ink that spues and the ink that do not spue.The amount etc. of considering the ink discharge-amount of nozzle number, each nozzle and should imposing on the ink of this peristome, determine that the position of the nozzle that spues and quantity etc. get final product.
In the situation that used the record-header with the constant nozzle row in nozzle interval, can, according to the length on nozzle interval and opening minister limit, calculate the nozzle number in indivedual patterns.The length on opening minister limit is the maximum number of the nozzle in indivedual patterns divided by the integral part of the resulting value in nozzle interval.Also the nozzle number that spues of the reality in indivedual patterns can be set for and is less than this maximum number.For example, in the situation that enter the maximum number of the nozzle of a peristome, be 5, can also not use the nozzle at two ends and it is made as to the non-nozzle that spues, by three central authorities of nozzle arrangement at five nozzles that spue.
As the concrete method for making of indivedual patterns, for example the nozzle that spues is specified to " 1 ", the non-nozzle that spues is specified to " 0 ".Invalid nozzle becomes the non-nozzle that spues certainly, keeps " 0 " as data.For example, in the situation that the nozzle number in indivedual pattern be 5 and all nozzles be all the nozzle that spues, as data, as " 11111 ", arrange the spue data " 1 " of nozzle of five expressions.For example, in the situation that without all nozzles are made as to the nozzle that spues, " 10101 " are such, only three nozzles in five effective nozzles are used as to the nozzle that spues.
In addition, in the situation that used the head of above-mentioned many ink droplets mode, can also, for the nozzle that spues, at length specify the quantity of ink spued.For example, in the situation that the nozzle of many ink droplets mode of eight gray scales, can be to the non-nozzle setting that spues " 0 ", to the quantity of ink that spues of the nozzle setting that spues " 1 "～" 7 " these seven grades.With similarly above-mentioned, in the situation that the nozzle number in indivedual pattern is five, can also be made as the central portion to peristome as " 13731 " and applies more ink, to the end of peristome, apply the such setting of ink of small amount.
In addition, even the maximum number of the nozzle in indivedual pattern is five, also can use two ends and be made as " 363 " such indivedual patterns that formed by three nozzles, and be configured in the central authorities of five nozzles.That is, its equivalent in meaning with " 03630 ".
(4) operation (c): complete printing write the design producing operation
In the present invention, according in above-mentioned operation (a) for the judgement operation of effective nozzle of all nozzles of a record-header and invalid nozzle and the indivedual patterns for the effective nozzle sets suitable with peristome made in above-mentioned operation (b), make for the seal of all nozzles of each record-header and write pattern.
That is, at all nozzles of each record-header, (in nozzle sequence number 1～N), insert above-mentioned indivedual patterns for effective nozzle sets, and the ink of registering each nozzle control data that spue.For invalid nozzle, certainly insert " 0 " and be registered as the non-nozzle that spues.
Like this, all complete and print the pattern write for N nozzle, but in the present invention importantly, guarantee in N nozzle that fixed number at the nozzle at both ends is as shift space.Usually this shift space is processed into to the non-nozzle that spues.As for as shift space, guaranteeing several nozzles, can suitably set according to the installation accuracy of nozzle interval and correct cellular installation head.
Like this, all register each ink control data that spue for N nozzle of the shift space that comprises both ends, complete thus about the full seal of a record-header and write pattern.To write pattern the shift space of having removed both ends and the part obtained is called actual seal writes pattern from full seal.
The method that correction is equipped on to the deviation about the nozzle arrangement direction of a plurality of record-headers in head unit describes.At first, under the state of head unit having been fixed to each record-header, try to print.Also can try with the non-recording medium of special use to print.
By examination, print, the landing positions of the ink of the benchmark nozzle from each record-header (being generally the nozzle of the some ends in left and right) is detected.According to the position of detecting and the coordinate of head unit, obtain the absolute coordinates of the benchmark nozzle of each record-header.Absolute coordinates according to the benchmark nozzle of each record-header, calculate the departure about each record-header of nozzle arrangement direction, uses the value at nozzle interval to obtain the shift amount of each record-header.
That is the relation that " shift amount=side-play amount ÷ nozzle interval ", arranged.
In the previous full seal of making is write pattern, by only utilizing partly the reality seal being write to pattern and staggering of the above-mentioned shift amount of obtaining in shift space, proofread and correct and determine about the full seal of each nozzle and write pattern.
For example, if the departure on the nozzle arrangement direction between each record-header be more than or equal to the nozzle interval 1/2 and be less than or equal to 3/2, make reality is printed and to write the stagger amount of of the nozzle of guaranteeing into shift space of pattern and proofread and correct.
Like this, the method according to this invention, can be so that the departure on the nozzle arrangement direction between each record-header be 1/2nd of nozzle interval in interior mode, proofreaies and correct.
In addition, for the deviation on the direction with nozzle arrangement direction quadrature, the i.e. deviation on main scanning direction in above-mentioned example, can print write timing by adjustment and proofread and correct.This is known usual way in the record that utilizes ink-jetting style to carry out.
(utilizability on industry)
According to the present invention, be easy to proofread and correct the record position deviation of the nozzle arrangement direction between a plurality of record-headers, without the installation site that makes record-header, self move, so without the device that possesses complicated travel mechanism, long time and the cost that also spend without the mobile operating of head etc., and can manufacture accurately color filter.
