Embodiment
(1) utilize ink-jetting style to make manufacturing method of color filter
Manufacturing method of color filter of the present invention is to utilize ink-jetting style to make the method for color filter, wherein, make that head unit that constitute scans arranging a plurality of on the main scanning direction with record-header on substrate, make the ink land that spue from said nozzle in the peristome of the unit of being divided by the black matrix (BM) that is formed on the aforesaid substrate, above-mentioned record-header has the nozzle row of having arranged a plurality of nozzles on sub scanning direction.
Below, use accompanying drawing that an example of embodiments of the present invention is elaborated.In addition, in the present example, show the manufacturing method of color filter that constitutes 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 that constitutes by yellow, magenta, blue-green, these four colors of black (YMCK).
Fig. 1 is a skeleton diagram of observing the head unit that is made 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 both can be a delegation shown in Figure 1, also can be multirow.Under the situation of multirow, by configuration that each nozzle row is staggered, can reduce apparent nozzle at interval in its orientation, can print and write meticulousr pattern.
When substrate is applied ink, make above-mentioned head unit towards direction of scanning X (main scanning direction) scanning (main sweep), and ink is spued on the substrate.In this case, as shown in Figure 1, on sub scanning direction, arrange a plurality of nozzles of each record-header usually, on main scanning direction, arranged each record-header that possesses this nozzle row side by side.
As record-header, can use and to set respectively from the spue record-header of many ink droplets (multidrop) mode of discharge-amount of ink of each nozzle.Used the head of so many ink droplets mode can change the ink discharge-amount that in peristome, spues, and prevented colour mixture according to the position of land.
Fig. 2 is the skeleton diagram that is formed with the substrate of BM.Peristome by the regularly arranged unit of dividing 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 the ink of same color respectively.Under the situation of the color filter of three looks, peristome 1,2,3 is capable as R respectively, G is capable, B capable (random order) and become one group unit repeatedly.
All peristomes on the substrate are applied the means of the ink of regulation as making head unit scanning shown in Figure 1, make head unit from the end of substrate towards a direction (main scanning direction go journey) scanning (main sweep), peristome on substrate applies ink simultaneously, when arriving opposed end, make its with the direction (sub scanning direction) of direction of scanning quadrature on carry out the subscan of the length suitable with head width.Next, make head unit carry out main sweep once more on the direction (backhaul) opposite with above-mentioned main scanning direction, the peristome on substrate applies ink simultaneously.
By carrying out this action repeatedly, even large-sized substrate also can use little head unit that substrate integral body is applied ink.In addition, even the substrate of various sizes also need not to change nozzle and can apply ink to integral body and makes color filter.
Direction (main scanning direction) as making head unit scanning is preferably the short side direction that is formed on the peristome on the substrate.At this moment, preferred 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 the direction of scanning, can use nozzle efficiently, 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 among 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 the substrate, make in advance and register at the seal of all nozzles in each record-header and write pattern (control data that spues of ink).
Can at first make the seal suitable and write pattern (indivedual pattern), and, make the seal of a head unit and write pattern (print entirely and write pattern) its application (insertions) all nozzles in this head unit with peristome.Wherein, in the nozzle that constitutes 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 of ink land to a peristome that spues on capable from the nozzle row of a record-header.As can be seen from Figure 3, under the situation of the ink that spues from all nozzles,,, the ink that spues on the boundary line of falling peristome and BM or on the BM is just arranged also as long as the ink that spues in the peristome of land is rightly arranged according to the position of peristome and nozzle relation.
But, make the ink land to the boundary line of peristome and BM or the phenomenon on the BM become the reason of colour mixture, and wasted ink is so should avoid.Therefore, in the present invention, in advance at 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 the BM (invalid nozzle), with not from the invalid nozzle ink that spues.
Promptly, method of the present invention comprises that (judge operation: operation (a)): is effective nozzle with the land in a plurality of nozzles in above-mentioned each record-header to the nozzle of the position of peristome to following operation, is invalid nozzle with land not to the nozzle of the position of peristome, at each above-mentioned record-header, judge it is effective nozzle or invalid nozzle for all nozzles.
The concrete grammar of judging is not particularly limited; But for example can according to the width of BM, the length on opening minister limit, judge effective nozzle and invalid nozzle at the nozzle of the N on the head by following formula (1).
＜formula 1 〉
D＜(A×E)％(B+C)＜(B-D) (1)
Wherein, in following formula (1), " % " is the meaning of getting remainder when carrying out division, and mark A～E represents 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 at interval
In addition, when judging effective nozzle and invalid nozzle by following formula (1), as prerequisite, need make the expression nozzle the position coordinate system initial point, with consistent by the initial point of the coordinate system of the length direction of the peristome of BM division.A～E in the 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 judging that by following formula (1) method of effective nozzle and invalid nozzle describes.
Nozzle sequence number A in above-mentioned (1) is illustrated in to have from an end and is arranged in the record-header of 1～N nozzle of delegation, the nozzle sequence number during from this end append serial numbers successively (noting, is No. 0 with the nozzle that overlaps with initial point).Therefore, " (A * E) " expression position (apart from the distance of an end) of nozzle in record-header of (nozzle sequence number A) arbitrarily.In addition, " (B+C) " expression is by the black matrix on the glass substrate (BM) and by the length of a group of constituting on this peristome long side direction in the peristome of this black matrix division.
With distance till the nozzle of nozzle sequence number A of from the beginning an end (remainder of A * E) obtain divided by (B+C) as till from the nearest peristome end of distance initial point side to the nozzle of nozzle sequence number A apart from F (F among Fig. 4) ((% (B+C)=F) of A * E).
For example, the nozzle 7 ' of the end from Fig. 4 the 14th (nozzle sequence number 14) from this initial point to this nozzle till distance be (14 * E), under the situation of the example of Fig. 4, deduct the remainder of the distance twice of (B+C), promptly (14 * E) divided by (B+C) remainder that obtains is F (with reference to Fig. 4).
For the ink with drop width that spues from nozzle (nozzle sequence number A) arbitrarily is not applied on the boundary line of peristome and BM and reliably land are in peristome, must make the length suitable with F among the nozzle sequence number A greater than 0 and less than the length B on opening minister limit (0＜F＜B).Satisfy at F under the situation of this condition, understand land in this peristome from the ink that spues of this nozzle.
But at this, has size owing to be applied to the drop of the ink on the substrate, so even F does not satisfy above-mentioned condition " 0＜F＜B ", only the end by will be from the beginning plays distance till the nozzle of nozzle sequence number A and be made as that (A * E), the ink that spues also has the situation on the boundary line of falling peristome and BM from the nozzle of nozzle sequence number A.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 the ink with drop width that spues from the nozzle of nozzle sequence number A is not applied on the boundary line of peristome and BM and reliably land are in peristome, and the F that must make nozzle sequence number A is greater than the enough and to spare width (D) of initial point side and less than deducting from the length on opening minister limit away from the enough and to spare width of a side of initial point and the value (B-D) that obtains.Therefore, the tighter condition that is used to make any nozzle become effective nozzle is " D＜F＜(B-D) ".Because F is that aforesaid (% (the B+C)=F of A * E) is so according to formula (1), effectively the condition of nozzle is " D＜(% (B+C)＜(B-D) of A * E) ".
For example under the situation of F smaller 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 the BM.In addition, for example under the situation of F 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 the BM.Therefore, which kind of situation no matter, the ink that spues all exceeds peristome ground land and can't apply ink reliably in peristome, so the nozzle of this nozzle sequence number A can't be made as effective nozzle.
Like this, under the situation that satisfies following formula (1), the nozzle land of nozzle sequence number A are judged as effective nozzle to the appropriate position of peristome.Under the situation that does not satisfy following formula (1), be judged as invalid nozzle.So,, can judge it is effective nozzle or invalid nozzle at all nozzles by carrying out this judgement at nozzle sequence number 1～N.
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 the ink droplet of reality, is not particularly limited, but preferably selects from the scope of 20～50 μ m.
In addition, be regarded as at interval under the constant situation, can judge by following formula (1) at nozzle; If but under the situation of the deviation that has the degree that to allow on the nozzle interval, can print the landing positions of measuring exactly from the ink of each nozzle by examination, and judge effective nozzle and invalid nozzle at each nozzle.
(3) operation (b): indivedual design producing operations
In the present invention, when writing pattern at all nozzles making seals in each record-header, nozzle sets with each record-header in following formula operation (a) is divided into effective nozzle sets and invalid nozzle sets, and make be used for to the ink relevant with peristome spue indivedual patterns of controlling (operation (b): indivedual design producing operations), facing to effective these indivedual patterns of nozzle sets insertion of the position of falling a peristome.
As the ink suitable with peristome spue indivedual patterns of control 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, need not all to spue ink to the effective nozzle that enters a peristome (the effective nozzles in indivedual patterns), also can in the effective nozzle in indivedual patterns, there be 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, the position of the nozzle of determining to spue and quantity etc. get final product.
Under the situation of having used record-header, can calculate the nozzle number in indivedual patterns according to the length of nozzle interval with opening minister limit with the constant nozzle row in nozzle interval.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 less than this maximum number.For example, be under 5 the situation at the maximum number of the nozzle that enters a peristome, can also not use the nozzle at two ends and it is made as the non-nozzle that spues, with three central authorities of nozzle arrangement that spue at five nozzles.
As the concrete method for making of indivedual patterns, for example the nozzle that spues is specified " 1 ", the non-nozzle that spues is specified " 0 ".Invalid nozzle becomes the non-nozzle that spues certainly, keeps " 0 " as data.For example, the nozzle number in indivedual patterns be 5 and all nozzles all be to spue under the situation of nozzle, as " 11111 ", arrange the spue data " 1 " of nozzle of five expressions as data.Need not all nozzles are made as under the situation of the nozzle that spues, for example " 10101 " are such, only three nozzles in five effective nozzles are used as the nozzle that spues.
In addition, under the situation of the head that has used above-mentioned many ink droplets mode, can also at length specify the quantity of ink that is spued at the nozzle that spues.For example, under the situation of 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, the nozzle number in indivedual patterns is under five the situation, can also be made as that the central portion to peristome applies more ink as " 13731 ", applies the such setting of more a spot of ink to the end of peristome.
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 constitute by three nozzles, and be configured in the central authorities of five nozzles.That is its equivalent in meaning with " 03630 ".
(4) operation (c): full seal is write the design producing operation
In the present invention, according in the above-mentioned operation (a) at the judgement operation of effective nozzle of all nozzles of a record-header and invalid nozzle and indivedual patterns of in above-mentioned operation (b), making at effective nozzle sets suitable with peristome, make at the seal of all nozzles of each record-header and write pattern.
That is, (in the nozzle sequence number 1～N), insert above-mentioned indivedual pattern, and the ink of registering each nozzle control data that spues at effective nozzle sets at all nozzles of each record-header.For invalid nozzle, certainly insert " 0 " and be registered as the non-nozzle that spues.
Like this, all finish the pattern write of seal, but in the present invention importantly, guarantee in N the nozzle that fixed number at the nozzle at both ends is as the space that is shifted at N nozzle.Usually the spatial manipulation Cheng Fei that should the be shifted nozzle that spues.As for will guaranteeing several nozzles as the displacement space, can according to nozzle at interval with the installation accuracy of head unit installation head is suitably set.
Like this, all register each ink control data that spues, finish thus about the full seal of a record-header and write pattern at N the nozzle in the displacement space that comprises both ends.To write the displacement space of having removed both ends the pattern and the part that obtains is called actual seal writes pattern from full seal.
The method about the deviation of nozzle arrangement direction that correction is equipped on a plurality of record-headers in the head unit describes.At first, under the state of head unit having been fixed each record-header, try seal.Also can use special-purpose non-recording medium to try seal.
By examination seal, the landing positions from the ink of the benchmark nozzle (being generally the nozzle of the some ends in the left and right sides) of each record-header 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 calculates the departure about each record-header of nozzle arrangement direction, uses nozzle value at interval to obtain the shift amount of each record-header.
That is the relation that " shift amount=side-play amount ÷ nozzle at interval ", arranged.
Formerly the full seal of Zhi Zuoing is write in the pattern, will only utilize partly the reality seal being write pattern and staggering of the above-mentioned shift amount of obtaining in the displacement space, and proofreaies and correct also definitely to write pattern about the full seal of each nozzle.
For example, if the departure on the nozzle arrangement direction between each record-header be more than or equal to nozzle at interval 1/2 and smaller or equal to 3/2, then make and the reality seal is write stagger one amount of the nozzle of guaranteeing into the displacement space of pattern 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 nozzle 1/2nd proofreading and correct in interior mode at interval.
In addition, for the direction of nozzle arrangement direction quadrature on deviation, the i.e. deviation on the main scanning direction in above-mentioned example, can proofread and correct by adjusting the seal write timing.This is known usual way in the record that utilizes ink-jetting style to carry out.
(utilizability on the 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 heads, need not to make the installation site self of record head to move, so need not to possess the device of complicated travel mechanism, also need not long time and the cost that the mobile operating etc. of head spends, and can make accurately colour filter.
