Description

本発明は、グラビア印刷などに使用される印刷インキの作製方法及び印刷インキ作製装置に関するものである。   The present invention relates to a printing ink production method and printing ink production apparatus used for gravure printing and the like.

グラビア印刷などに使用される印刷インキは、主に前回の印刷時に使用した印刷インキの余り（残インキ）に、色インキ原液、メジウム原液及び希釈溶剤（インキ配合材）を追加することにより新たなインキが作製されている。この作製された印刷インキの印刷濃度の調整は、例えば、残インキにインキ配合材をそれぞれ添加し、試し刷りを行ないながら所望の印刷濃度にしたり、品質確認用の印刷機で印刷濃度を確認して調整したり、色変換方式（ＣＣＭ）で調整したりしている（例えば、特許文献１）。   Printing inks used for gravure printing, etc. are new by adding color ink stock solution, medium stock solution and dilution solvent (ink compounding material) to the remainder of the printing ink used at the time of previous printing (residual ink). Ink is made. Adjustment of the printing density of the produced printing ink can be achieved, for example, by adding an ink compounding material to the remaining ink to obtain a desired printing density while performing a test print, or by checking the printing density with a printing machine for quality confirmation. Or by a color conversion method (CCM) (for example, Patent Document 1).

しかし、品質確認用の印刷機を使用した場合では、本刷り用の印刷機との印刷濃度の再現性が異なり、ＣＣＭを使用した場合では、ＣＣＭの装置が非常に高価であり、また、防爆仕様が必要である印刷現場に設置できないなどの問題点がある。
特許文献１は、印刷見本の色別配合比率データに基づいて調色した印刷インキを試し刷りし、その刷ったインキを測色器により測色し、測色結果と色別配合比率データとの誤差が零又は限りなく零に近づくように更に調色するという方法であるが、このような方法は、所望の印刷インキを作製するまで、試し刷りを複数回必要としており、作業の手間や、インキの消費量が増えてしまうなどの問題がある。
特開２００１−６３００６号公報 However, when using a printing press for quality confirmation, the reproducibility of printing density differs from that for a main printing press, and when using a CCM, the CCM device is very expensive and explosion-proof. There are problems such as being unable to install at a printing site where specifications are required.
Japanese Patent Laid-Open No. 2004-133826 prints a printed ink that is toned based on the color-specific composition ratio data of a printing sample, measures the color of the printed ink with a colorimeter, and compares the colorimetric result with the color-specific composition ratio data. Although it is a method of further toning so that the error is zero or as close to zero as possible, such a method requires a plurality of trial printings until the desired printing ink is produced, There are problems such as an increase in ink consumption.

続いて、実施例の印刷インキ作製装置１０の使用方法について説明する。図２は、実施例の印刷インキ作製装置の動作を示すフローチャートである。
印刷インキ作製装置１０の制御演算部１４は、電源が投入されることで印刷インキ作製作業を開始し（Ｓ１００）、入力部１５から所望の印刷インキの印刷濃度、粘度及び重量の設定値の入力を作業者に求める（Ｓ１０１）。作業者により入力されたら、残インキの有無を確認する（Ｓ１０２）。 Then, the usage method of the printing ink preparation apparatus 10 of an Example is demonstrated. FIG. 2 is a flowchart showing the operation of the printing ink production apparatus according to the embodiment.
The control calculation unit 14 of the printing ink production apparatus 10 starts the printing ink production work when the power is turned on (S100), and inputs the set values of the printing density, viscosity and weight of the desired printing ink from the input unit 15. (S101). If input is made by the operator, the presence or absence of residual ink is confirmed (S102).

残インキがなく、新規に所望の印刷インキを作製する場合は（Ｓ１０２、Ｎｏ）、空のインキ容器２０をインキ配合部１６に設置することを作業者に求め（Ｓ１０３）、設置されたら、入力された所望の印刷インキの印刷濃度、粘度及び重量の設定値に基づいて、インキ配合材の配合量を演算する（Ｓ１０４）。
残インキがある場合は（Ｓ１０２、Ｙｅｓ）、残インキの入ったインキ容器２０をインキ配合部１６に設置することを作業者に求め（Ｓ１０５）、設置されたら、残インキ印刷物２１の印刷濃度を測色器１１により測定し、残インキの粘度及び重量を粘度計１２及び重量計１３により測定する（Ｓ１０６）。測定値を入力した制御演算部１４は、所望の印刷インキの設定値及び残インキの測定値に基づいて、所望の印刷インキ及び残インキの配合量を演算し（Ｓ１０７）、その演算結果より残インキに加えるインキ配合材の配合量を演算する（Ｓ１０８）。 When there is no remaining ink and a desired printing ink is newly produced (S102, No), the operator is requested to install an empty ink container 20 in the ink blending unit 16 (S103). The blending amount of the ink blending material is calculated based on the set values of the printing density, viscosity, and weight of the desired printing ink (S104).
When there is residual ink (S102, Yes), the operator is requested to install the ink container 20 containing the residual ink in the ink blending unit 16 (S105). The measurement is performed by the colorimeter 11, and the viscosity and weight of the remaining ink are measured by the viscometer 12 and the weight meter 13 (S106). The control calculation unit 14 that has input the measurement value calculates the blending amount of the desired printing ink and the remaining ink based on the setting value of the desired printing ink and the measurement value of the remaining ink (S107). The blending amount of the ink blending material added to the ink is calculated (S108).

FIG. 3 is a diagram showing the measurement results and approximate expression of the relationship between the color ink (cyan ink) stock solution in printing ink and the printing density, and FIG. 4 is the color ink (cyan ink) stock solution and the diluting solvent necessary for it. FIG. 5 shows the measurement results and approximate expressions of the relationship between the weight ratio of the medium stock solution and the necessary dilution solvent and the viscosity. FIG. In addition, each measured value shown to FIGS. 3-5 is measured when the temperature of printing ink is 20 degreeC.

上述したように色インキ原液はシアンインキ原液を用いたときであり、印刷濃度（シアン）０．９７３［Ｄ］、粘度１３［秒］、重量１０［ｋｇ］の残インキを使用して、印刷濃度（シアン）１．７０８［Ｄ］、粘度１５［秒］、重量１０［ｋｇ］の印刷インキ（所望の印刷インキ）を作製するときの演算を示す。なお、所望の印刷インキの重量の算出は、１ｍ2当たりのインキ消費重量、印刷数量及び最低インキ循環重量より求めることができる。本実施例では、１ｍ2当たりのインキ消費重量が０．００２［ｋｇ／ｍ2］、印刷数量が２５００［ｍ2］、最低インキ重量が５［ｋｇ］であり、０．００２×２５００＋５により、所望の印刷インキの重量が１０ｋｇと求められる。 As described above, the color ink stock solution is when the cyan ink stock solution is used, and printing is performed using the residual ink having a printing density (cyan) of 0.973 [D], a viscosity of 13 [seconds], and a weight of 10 [kg]. An operation for producing a printing ink (desired printing ink) having a density (cyan) of 1.708 [D], a viscosity of 15 [seconds], and a weight of 10 [kg] is shown. The calculation of the weight of the desired printing ink can be obtained from the ink consumption weight per 1 m 2 , the printing quantity, and the minimum ink circulation weight.

In addition, X in each formula shows the viscosity [second] of the dilution solvent necessary for the medium stock solution and the medium stock solution, and Y indicates the weight ratio [%] of the dilution solvent necessary for the medium stock solution and the medium stock solution.
The total weight of the diluting solvent is the sum of the diluting solvent necessary for the color ink stock solution described in Formulas 3 and 4 and the diluting solvent necessary for the medium stock solution.

次に、制御演算部１４において、所望の印刷インキのインキ配合材の配合量を演算する。まず、所望の印刷インキの設定値（印刷濃度１．７０８［Ｄ］、粘度１５［秒］、重量１０［ｋｇ］）より、所望の印刷インキ中の色インキ原液の重量割合を求める。粘度の設定値が１５［秒］であるので、式２を使用し、式２のＹに印刷濃度の設定値１．７０８［Ｄ］を代入し、Ｘである所望の印刷インキ中の色インキ原液の重量割合を求める。演算すると、Ｘは、３２．９４［％］となる。
続いて、色インキ原液を粘度１５［秒］にするために必要な希釈溶剤と、色インキ原液との重量比を式３により求める。式３のＸに粘度１５［秒］を代入すると、色インキ原液及び希釈溶剤との重量比であるＹは５５．２０％となり、所望の印刷インキ中の色インキ原液に必要な希釈溶剤の重量割合は、１８．２８［％］となる。 Next, the control calculator 14 calculates the blending amount of the desired ink blending material for the printing ink. First, the weight ratio of the color ink stock solution in the desired printing ink is obtained from the set values of the desired printing ink (printing density 1.708 [D], viscosity 15 [seconds], weight 10 [kg]). Since the viscosity setting value is 15 [seconds], Equation 2 is used, the printing density setting value 1.708 [D] is substituted into Y in Equation 2, and X is the color ink in the desired printing ink. Determine the weight ratio of the stock solution. When calculated, X becomes 32.94 [%].
Subsequently, the weight ratio of the diluting solvent and the color ink stock solution required for setting the color ink stock solution to a viscosity of 15 [seconds] is obtained by Equation 3. When the viscosity of 15 [seconds] is substituted for X in Formula 3, Y, which is the weight ratio between the color ink stock solution and the dilution solvent, is 55.20%, and the weight of the dilution solvent necessary for the color ink stock solution in the desired printing ink The ratio is 18.28 [%].

また、同様にして、メジウム原液を粘度１５［秒］にするために必要な希釈溶剤と、メジウム原液との重量比を式４により求める。式４のＸに粘度１５［秒］を代入すると、メジウム原液及び希釈溶剤との重量比であるＹは５４．００％となり、所望の印刷インキ中のメジウム原液の重量割合は３１．５４［％］、また、メジウム原液に必要な希釈溶剤の重量割合は１７．２４［％］となる。
以上の演算結果をまとめると、所望の印刷インキに必要なインキ配合材の重量割合は、色インキ原液３２．９４［％］、メジウム原液３１．５４［％］、希釈溶剤３５．５２［％］となり、配合量は、この配分の重量割合に所望の印刷インキの重量の設定値１０［ｋｇ］を乗算した結果となるので、色インキ原液３．２９４［ｋｇ］、メジウム原液３．１５４［ｋｇ］、希釈溶剤３．５５２［ｋｇ］となる。仮に、新規に所望の印刷インキを作製する場合は、この配分量でインキ配合材を混ぜることにより、作製することが可能となる。 Similarly, the weight ratio of the diluent solvent required to make the medium stock solution a viscosity of 15 [seconds] and the medium stock solution is obtained by Equation 4. When the viscosity of 15 [seconds] is substituted for X in Formula 4, Y which is the weight ratio of the medium stock solution and the dilution solvent is 54.00%, and the weight ratio of the medium stock solution in the desired printing ink is 31.54 [% In addition, the weight ratio of the dilution solvent necessary for the medium stock solution is 17.24 [%].
Summarizing the above calculation results, the weight ratio of the ink blending material necessary for the desired printing ink is as follows: color ink stock solution 32.94 [%], medium stock solution 31.54 [%], dilution solvent 35.52 [%] The blending amount is the result of multiplying the weight ratio of this distribution by the set value 10 [kg] of the weight of the desired printing ink, so that the color ink stock solution 3.294 [kg] and the medium stock solution 3.154 [kg] ] And diluted solvent 3.552 [kg]. If a desired printing ink is newly produced, it can be produced by mixing the ink blending material in this distribution amount.

次に、残インキの配合量を求める。残インキは、印刷濃度０．９７３［Ｄ］、粘度１３［秒］、重量１０［ｋｇ］なので、上述した所望の印刷インキの配合量の演算と同様にして、まず、粘度が１３［秒］であるので、式１を使用し、印刷濃度の設定値０．９７３［Ｄ］をＹに代入し、残インキ中の色インキ原液の重量割合（Ｘ）を１９．４０［％］と求める。
続いて、式３のＸに粘度１３［秒］を代入して色インキ原液及び色インキ原液に必要な希釈溶剤との重量比であるＹを８９．０６％と求め、その値から残インキ中の色インキ原液に必要な希釈溶剤の重量割合１７．３２［％］を求める。更に、式４のＸに粘度１３［秒］を代入し、メジウム原液及びメジウム原液に必要な希釈溶剤との重量比であるＹを８３．５１％と求め、その値から残インキ中のメジウム原液の重量割合３４．４６［％］と、残インキ中のメジウム原液に必要な希釈溶剤の重量割合２８．８２［％］とを求める。 Next, the blending amount of the residual ink is obtained. Since the remaining ink has a printing density of 0.973 [D], a viscosity of 13 [seconds], and a weight of 10 [kg], the viscosity is first 13 [seconds] in the same manner as the calculation of the desired amount of the printing ink. Therefore, using Equation 1, the printing density set value 0.973 [D] is substituted for Y, and the weight ratio (X) of the color ink stock solution in the remaining ink is obtained as 19.40 [%].
Subsequently, by substituting the viscosity of 13 [seconds] into X in Formula 3, Y, which is the weight ratio of the color ink stock solution and the dilution solvent necessary for the color ink stock solution, is determined to be 89.06%, and from that value, The weight ratio 17.32 [%] of the diluting solvent necessary for the color ink stock solution is obtained. Further, by substituting the viscosity 13 [seconds] into X in Formula 4, Y, which is the weight ratio of the medium stock solution and the dilution solvent necessary for the medium stock solution, is determined to be 83.51%, and from this value, the medium stock solution in the remaining ink Weight ratio of 34.46 [%] and a weight ratio of 28.82 [%] of the diluting solvent necessary for the medium stock solution in the residual ink.

以上の演算結果をまとめると、残インキに必要なインキ配合材の重量割合は、色インキ原液１９．４０［％］、メジウム原液３４．４６［％］、希釈溶剤４６．１４［％］となり、配合量は、この配分の重量割合に所望の印刷インキの重量の設定値１０［ｋｇ］を乗算した結果となるので、色インキ原液１．９４０［ｋｇ］、メジウム原液３．４４６［ｋｇ］、希釈溶剤４．６１４［ｋｇ］となる。   Summarizing the above calculation results, the weight ratio of the ink compounding material required for the remaining ink is 19.40 [%] color ink stock solution, 34.46 [%] medium stock solution, 46.14 [%] dilution solvent, The blending amount is a result of multiplying the weight ratio of this distribution by the set value 10 [kg] of the weight of the desired printing ink, so that the color ink stock solution 1.940 [kg], the medium stock solution 3.446 [kg], The dilution solvent becomes 4.614 [kg].

次に演算した所望の印刷インキの配合割合及び残インキの配合割合から、残インキに加えるインキ配合材の配合量を演算する。
まず、残インキのインキ配合材の重量割合と所望の印刷インキのインキ配合材の重量割合との比を求め、最大となる値を選定すると、希釈溶剤の比が１．２９９と最大になる。これは、所望の印刷インキに必要な希釈溶剤が、残インキの希釈溶剤よりも少ないことを意味しており、この場合は、残インキの全てを使い切ることができないことを示している。
この希釈溶剤の比１．２９９を、所望の印刷インキの重量割合に乗算し、その結果から残インキの重量割合を減算すると、残インキ１００［％］に対して追加すべきインキ配合材の重量割合、色インキ原液２３．３９［％］、メジウム原液６．５１［％］、希釈溶剤０［％］が求まる。 Next, from the calculated blending ratio of the desired printing ink and the blending ratio of the remaining ink, the blending amount of the ink blending material added to the remaining ink is calculated.
First, when the ratio of the weight ratio of the ink composition of the residual ink to the weight ratio of the ink composition of the desired printing ink is determined and the maximum value is selected, the ratio of the dilution solvent is maximized to 1.299. This means that the dilution solvent required for the desired printing ink is less than that of the residual ink, and in this case, all of the residual ink cannot be used up.
When the weight ratio of the desired printing ink is multiplied by the dilution solvent ratio of 1.299 and the weight ratio of the remaining ink is subtracted from the result, the weight of the ink blending material to be added to the remaining ink of 100 [%]. The ratio, the color ink stock solution 23.39 [%], the medium stock solution 6.51 [%], and the dilution solvent 0 [%] are obtained.

以上をまとめると、残インキ１００［％］、色インキ原液２３．３９［％］、メジウム原液６．５１［％］、希釈溶剤０［％］となり、重量割合の合計は、１２９．９［％］となる。１２９．９［％］が所望の印刷インキの重量である１０［ｋｇ］となるように演算すると、使用する残インキの重量及び追加するインキ配合材の配分量はそれぞれ、残インキ７．６９８［ｋｇ］、色インキ原液１．８０１［ｋｇ］、メジウム原液０．５０１［ｋｇ］、希釈溶剤０［ｋｇ］となる。なお、残インキは１０［ｋｇ］あったが、前述したように、そのうちの７．６９８［ｋｇ］を使用し、残りは次回の印刷インキ作製に残しておくことができる。   In summary, the residual ink is 100%, the color ink stock solution is 23.39 [%], the medium stock solution is 6.51%, the dilution solvent is 0%, and the total weight ratio is 129.9%. ]. When calculating so that 129.9 [%] becomes 10 [kg] which is the weight of the desired printing ink, the weight of the remaining ink to be used and the distribution amount of the ink compounding material to be added are respectively 7.698 [ kg], color ink stock solution 1.801 [kg], medium stock solution 0.501 [kg], and diluted solvent 0 [kg]. Although the remaining ink was 10 [kg], as described above, 7.698 [kg] of the remaining ink can be used, and the remaining can be left for the next printing ink preparation.

実際に作製した印刷インキの評価結果を表１に示す。表１に示すように、所望の印刷インキの設定値に対し、作製した印刷インキの印刷濃度の誤差は０．０２６［Ｄ］であり、本発明の作製方法による効果が十分にあることが確認することができる。
