A chamber 164 into which the paper clearing agent 2 is placed is in contact with the outer peripheral surface of the anilox roller 163.

  As shown in FIG. 2, the chamber 164 is connected to a delivery port of a feed pump 165 that feeds the paper clearing agent 2 into the chamber 164. The inlet of the feed pump 165 is connected to a tank 166 that stores the paper clearing agent 2. A lower portion of the chamber 164 is connected to the tank 166. The tank 166 is provided with a temperature regulator 167 for adjusting the internal temperature and a temperature sensor 168 for measuring the internal temperature. The temperature sensor 168 is electrically connected to the input unit of the control device 169. The output unit of the control device 169 is electrically connected to the temperature regulator 167, and the control device 169 makes the paper transparency in the temperature regulator 167 based on the detection output of the temperature sensor 168. The temperature regulator 167 can be controlled so as to maintain the agent 2 at a predetermined temperature.

  As shown in FIG. 1, a paper discharge device 190 communicates with the pressure drum 161 of the transparency processing unit 160 on the downstream side in the transport direction of the sheet 1 via the paper discharge drum 107. A sprocket 191 is coaxially provided on the discharge cylinder 107. A sprocket 192 is disposed in the vicinity of the paper discharge tray 194 of the paper discharge device 190. A paper discharge chain 193 is wound between the sprockets 191 and 192.

  The paper clearing agent 2 has various types. For example, a polymer material such as a recyclable resin having substantially the same optical refractive index as the cellulose fiber constituting the sheet 1 is used as an organic solvent or the like. And those dissolved in

  In this embodiment, the printing unit 120, 130, 140, 150, etc. constitute a printing device, and the anilox roller 163, the chamber 164, etc. constitute a paper clearing agent supply device, The paper clearing agent supply device, the pressure drum 161, the coater drum 162, etc. constitute a paper clearing agent transfer device, and the feed pump 165, the tank 166, etc. constitute a paper clearing agent circulation device. The paper clearing agent circulation device, the temperature adjuster 167, the temperature sensor 168, the control device 169, etc. constitute a viscosity adjusting device (temperature adjusting device), and the paper clearing agent transfer device and the viscosity adjusting device. The apparatus or the like constitutes a transparency processing unit 160 that is a paper transparency processing apparatus according to the present invention.

  Next, the operation of the single-sided sheet-fed printing press 100 according to this embodiment will be described. In this single-sided sheet-fed printing press 100, a transparent window is formed in a part of the sheet 1 by the transparency processing unit 160, and the transparent unit is excluded by the printing units 120, 130, 140, and 150. To print.

  First, the sheets 1 on the paper stack 111 supplied one by one by the paper feeding device 110 are transferred to the impression cylinder 121 of the first printing unit 120 via the feeder board 101 and the swing device 102, and It is held by the impression cylinder 121 and conveyed. Ink is transferred from the plate cylinder 123 to the rubber cylinder 122, and when the sheet 1 passes between the impression cylinder 121 and the rubber cylinder 122, printing pressure is applied between the cylinders 121 and 122. The ink on the rubber cylinder 122 is transferred to one side of the sheet 1 and the first color is printed.

  The sheet 1 on which the first color printing has been performed is transferred from the impression cylinder 121 to the impression cylinder 131 of the second printing unit 130 via the transfer cylinder 103, and on the rubber cylinder 132 on one surface of the sheet 1. The second ink is transferred and the second color is printed. Thereafter, similarly, the third printing unit 140 performs printing of the third color on one side of the sheet 1 and the fourth printing unit 150 performs printing of the fourth color on one side of the sheet 1. . The sheet 1 held on the impression cylinder of the fourth printing unit 150 is transferred to the impression cylinder 160 of the transparency processing unit 160 via the transfer cylinder 106.

  The paper clearing agent 2 in the chamber 164 of the clearing processing unit 160 is supplied to the anilox roller 163. The clearing agent 2 accommodated in a large amount in the cell of the anilox roller 163 is transferred to the plate of the coater cylinder 162. When the sheet 1 held by the impression cylinder 161 passes between the impression cylinder 161 and the coater cylinder 162, a printing pressure is applied between the impression cylinders 161 and 162, and the sheet 1 The paper clearing agent 2 on the plate of the coater cylinder 162 is printed (transferred) on one side.

  At this time, the control device 169 keeps the paper clearing agent 2 at a predetermined temperature (for example, about 35 to 45 ° C.), that is, the paper clearing agent 2 always has a predetermined viscosity (for example, The temperature regulator 167 is controlled based on the detection output of the temperature sensor 168 so that the measured value using the Zahn cup No. 4 is about 5 to 30 seconds). The temperature of the clarifying agent 2 is always adjusted. Then, the paper clearing agent 2 is circulated between the tank 168 and the chamber 164 by the feed pump 165, so that the paper clearing agent 2 having an appropriate viscosity is always supplied from the chamber 164 to the anilox roller 163.

  The paper clearing agent 2 thick-printed (transferred) on the sheet 1 penetrates into and enters the fine gaps between the cellulose fibers constituting the sheet 1, for example, When the organic solvent is volatilized and the polymer material embeds the gap, the difference in optical refractive index between the cellulose fiber and the gap is almost eliminated. As a result, the sheet 1 is substantially equal without causing irregular reflection (whitening / opacity) due to a difference in the refractive index of light at the interface between the cellulose fibers and the voids inside the paper clearing agent 2. Since light can travel at a refractive index, the portion printed (transferred) with the paper clearing agent 2 becomes transparent.

  Then, the sheet 1 on which the paper clearing agent 2 is thickly printed (transferred) on one side of the sheet 1 is the nail clip nail provided on the paper discharge chain 193 of the paper discharge device 190. Then, the pressure drum 161 is transported through the paper discharge cylinder 107, and is discharged onto the paper discharge table 194.

  When the ink and the paper clearing agent 2 are printed (transferred) on one side of the sheet 1 in this way, the ink is printed on the other side of the sheet 1 in the same manner as described above. At the same time, printing (transfer) of the paper clearing agent 2 is performed on the portion on the other side corresponding to the portion on one side.

  As a result, the paper clearing agent 2 is printed (transferred) from both sides of the one side and the other side of the sheet 1 to form a transparent window having a necessary and sufficient degree of transparency. The

  In the operation of the single-sided sheet-fed printing press 100 according to this embodiment, the sheet feeding process is performed by supplying the sheet 1 with the sheet feeding device 110 or the like, and the printing units 120, 130, 140, 150 and the transparent cylinder unit 160, the transfer cylinders 103, 106, the transfer cylinders 103 to 106, the discharge cylinder 107, and the like. A printing process is performed by printing on the sheet 1 with the units 120, 130, 140, and 150, and the paper clearing agent 2 is adjusted by adjusting the temperature of the paper clearing agent 2 with the viscosity adjusting device (temperature adjusting device). 2 is performed by adjusting the viscosity of No. 2, and the transfer process is performed by printing (transferring) the paper clearing agent 2 on the sheet 1 by the transparency processing unit 10, and the sheet is discharged by the paper discharge device 190 or the like. Leaf paper 1 It forms a paper discharge step by discharge.

  That is, in the present embodiment, the paper clearing agent 2 is always printed (transferred) to the sheet 1 via the coater cylinder 162 by the anilox roller 163 while maintaining the predetermined temperature (viscosity). It is.

  Therefore, a large amount of the paper clearing agent 2 can be transferred to the plate of the coater cylinder 162 by the anilox roller 163 and a large amount of the paper clearing agent 2 can be printed (transferred) on the sheet 1. With the paper clearing agent 2 adjusted to have a high viscosity, the fine gaps between the cellulose fibers of the sheet 1 can be filled in a short time, that is, the penetration into the sheet 1 can be accelerated. Therefore, the transparent window can be formed efficiently.

  Therefore, according to the present embodiment, it is possible to ensure that the paper clearing agent 2 is always printed (transferred) in a necessary and sufficient amount on the portion of the sheet 1, so that there are few transparent windows on the sheet 1. It can be reliably formed by the number of times (on each side of the front and back surfaces, or twice only on one side), and the working efficiency for forming the transparent window can be improved.

  In addition, since printing on the sheet 1 and formation of the transparent window can be performed with a single paper thread, there is no misregistration between the printing and the formation of the transparent window, and the work efficiency is greatly increased. Can be improved.

  Further, by exchanging the plate of the coater cylinder 162, the position, shape, size and number of the transparent windows with respect to the sheet 1 can be easily changed, and the change of the printed matter can be easily handled. it can.

  Further, the control device 140 controls the temperature adjuster 167 based on the detection output of the temperature sensor 168 to constantly adjust the temperature of the paper clearing agent 2, whereby the viscosity of the paper clearing agent 2 is adjusted. In other words, since the viscosity of the paper clearing agent 2 is controlled by adjusting the temperature, the viscosity adjusting mechanism of the paper clearing agent 2 can be easily incorporated into the clearing processing unit 160, It is possible to easily print (transfer) the paper clearing agent 2 having an appropriate viscosity.

  The viscosity of the paper clearing agent 2 is Zahn cup no. The measured value using 4 is preferably about 5 to 30 seconds (particularly preferably 10 to 20 seconds). This is because, when the viscosity of the paper clearing agent 2 exceeds 30 seconds, the anilox roller 163 reduces the thickness printing (transfer) amount to the portion of the sheet 1 and the gap of the sheet 1 On the other hand, when the viscosity of the paper clearing agent 2 is less than 5 seconds, the amount of the paper 1 that permeates without staying in the gap is reduced. When there are too many sheets 1, the sheets 1 stick to the adjacent sheets 1 and may cause blocking, and not only the thickness direction of the sheets 1 but also the vertical direction and the width direction (surface) This is because it may permeate excessively in the direction) and cause “bleeding” around the transparent window.
