Description

The present invention relates to a recording apparatus and a recording material that include a recording execution unit that records on a recording material to be conveyed, and a color measurement unit that performs colorimetry on a recording site recorded on the recording medium by the recording execution unit The present invention relates to a method for drying and measuring a colorimetric pattern for drying and measuring a colorimetric pattern recorded in the above.

  At the production site of printed matter, a proof is printed before entering the main printing, and the image data is faithfully printed with reference to the image displayed on the proofed print sample and the authentication color patch displayed together with the image. Conventionally, color calibration for confirming whether a color is reproduced has been performed.

  On the other hand, the color of the image on the CRT monitor and the color of the image displayed on the print sample output from the output device such as a printer or an image setter are electronically based on a color management file called a profile. Digital matching for matching is widespread and is implemented at the production site of print data and the production site of printed matter.

  Recently, in order to shorten the time required for proof printing, a form of color proofing called simple proofing, in which proof paper is output directly from printing data for plate making, has been widely used. A large-sized ink jet printer is used for the output. When proof paper is output using a large ink jet printer, the color information for the color patch for authentication and the color patch for profile creation is measured using a measuring instrument called a colorimeter. Based on the measurement result, a correction value is obtained by comparison with the color of the print data on the CRT monitor, and the color correction information is supplied to a printer driver which is a recording control device of the ink jet printer.

  A color proofer in which such a colorimeter is attached to a carriage on which a recording head of an inkjet printer is mounted, and a calibration method using the color proofer are disclosed in Patent Document 1 below. Yes.

  However, in the case of such a color proofer, a colorimeter is directly attached to the carriage for scanning the recording head, and the colorimetry is performed until the colorimetric pattern recorded on the recording material dries. Since the vessel could not be scanned, it had to wait for a long time of about 15 minutes in the case of natural drying.

In this case, it may be possible to shorten the drying time by combining a forced dryer and a colorimeter with respect to the printer body. However, when the heat of the forced dryer acts on the colorimeter, accurate color information cannot be obtained, and the heat of the forced dryer adversely affects the surrounding environment including the nearby recording head.

  The drying device 83 is a hot air drying device in the present embodiment, and a suction fan 84 that takes in air G from the outside, a heater 89 that warms the air G that has been taken in, and air G that has been taken in by the suction fan 84 into hot air H Alternatively, the air guide 85 that leads to the drying region 81 downstream of the colorimetric region 80 with the cold air L and the warm air H or the cold air L blown out through the air guide 85 is the color measuring device 82 side described above. And a blowout cover 86 that is directed so as to be blown obliquely toward the downstream area.

  The suction fan 84 is accommodated in a rectangular tube-shaped fan box 87 provided at an end portion on the return position side, and takes in external air G from an intake port 88 formed on an end surface of the fan box 87. It is configured to be supplied into an air guide 85 to be described later. The heater 89 is provided next to the fan box 87 and, like the fan box 87, is accommodated in a heater box 90 having a rectangular tube shape. Note that the air G supplied into the air guide 85 becomes hot air H and cold air L by switching the heater 89 between the ON and OFF states.

  The air guide 85 is a rectangular box-like member that is long in the column direction C formed by the colorimetric pattern in which the rear surface facing the colorimetric device 82 and the end surface on the side connected to the heater box 90 are opened.

  The drying device 83 and the color measurement device 82 are covered with a common cover 30 as shown in FIGS. With this cover 30, the inside of the cover 30 becomes negative pressure due to the blowing of wind from the wind outlet 92, and the outside air is sucked into the cover 30, so that the entire colorimetric device 82 and the drying device 83 can be cooled effectively. . This cooling effect is exhibited both when hot air is blown out and when cold air is blown out.

Next, the operation of the recording apparatus according to the present invention configured as described above will be described according to the method for drying / colorimetry of the colorimetric pattern of the present invention shown in FIG.
The colorimetric pattern drying / colorimetry method of the present invention includes (1) a dry region feeding step shown in FIG. 10A, (2) a colorimetric pattern drying step shown in FIG. 10 (c), (3) a colorimetric environment stabilization step, (4) a colorimetric region return step shown in FIG. 10 (d), and (5) a colorimetric execution step shown in FIG. 10 (e). It is configured by executing sequentially.

(1) Drying area feeding step (see FIG. 10A)
In this step, the roll paper R and the cut sheet P on which the color patch B is recorded are passed through the color measurement area 80 and conveyed so that the color patch B is positioned in the drying area 81 downstream of the color measurement area 80. Specifically, the transport driving roller 19 is rotated in the forward rotation direction to transport the roll paper R or the cut sheet P in the feed direction A below the front portion, and the end of the roll paper R or the cut sheet P is detected. The position is detected by a start edge detection sensor 93 provided at an appropriate position, and when the color patch B recorded on the roll paper R or the cut sheet P reaches the drying area 81, the rotation of the transport driving roller 19 is stopped.

(2) Color measurement pattern drying step (see FIG. 10B)
In this step, hot air H is blown against the color patch B recorded on the roll paper R or the cut paper P sent to the drying area 81 to promote drying of the color patch B. Specifically, the suction fan 84 and the heater 89 are operated to warm the air G taken from the outside by the suction fan 84 to warm air H, and the warm air H is sent into the air guide 85. Then, the hot air H is supplied to each flow path partitioned by the guide fins 91 in the air guide 85, and the hot air H is uniformly applied toward the color patch B from the air outlet 92 of the blowout cover 86, so that the color patch B is applied. Dry. In addition, the drying time in this process is 2 to 3 minutes, and the drying time is significantly shortened compared with the conventional drying time of around 15 minutes.

  Further, although colorimetry is not performed in this colorimetric pattern drying step, the pressing member 34 in the colorimetry device 82 takes a pressing posture in close contact with the recording material. Thereby, the pressing member 34 functions as a shield plate against the warm air, and prevents the warm air H from flowing to the recording head 13 side. Therefore, the recording quality of the recording head 13 which has a temperature sensor and responds sensitively to temperature and is easily affected is also prevented. Further, since the warm air H (also cool air L) blown out from the air outlet 92 is directed obliquely forward and downstream, it acts only on the roll paper R and the cut sheet paper P on which the color patch B is recorded. In addition, heat is not easily transmitted to the conveyance guide plate 11 and the upstream color measurement device 82.

(3) Colorimetric environment stabilization process (see FIG. 10C)
In this step, the color patch B is further blown with cold air L to lower the temperature of the roll paper R, the cut paper P, and the surrounding environment. Specifically, only the suction fan 84 is operated, and the air G taken in from the outside by the suction fan 84 is sent as cold air L into the air guide 85 as it is, and from the air outlet 92 of the blowout cover 86 toward the color patch B. The cold air L is uniformly applied to lower the temperature of the roll paper R, the cut paper P or the like to the initial temperature. The properties of the roll paper R and the cut paper P and the surrounding environment are stabilized due to the decrease in temperature.

(4) Colorimetric region return step (see FIG. 10D)
In this step, the roll paper R and the cut sheet P in which the color patch B is located in the drying area 81 are returned to the upstream side, and the color patch B is located in the color measurement area 80. Specifically, the pressing member 34 is returned to the retracted position, the transport drive roller 19 is rotated in the reverse direction, and the roll paper R and the cut sheet P are returned to the return direction F above the rear portion, and the roll paper R and the single paper When the color patch B recorded on the slip sheet P is positioned in the color measurement region 80, the rotation of the transport drive roller 19 is stopped.

(5) Color measurement execution process (see FIG. 10E)
In this step, color measurement is performed on the color patch B that has returned to the color measurement region 80. Specifically, the pressing member drive motor 70 is actuated to rotate the pressing member 34 in the state of jumping downward to press the pressing plate 48 on the surface of the roll paper R or the cut sheet P around the color patch B. The roll paper R and the cut paper P are fixed on the conveyance guide plate 11 by closely contacting each other. Next, the carriage drive motor 54 is operated to move the color measuring device carriage 51 from the home position to the color measuring region 80, and the color measuring device 31 is moved toward the return position.

  At this time, in a state in which a part of the lower end portion of the colorimeter 31 has entered a long hole 49 formed in the holding plate 48, the tracking function by the tracking mechanism 44 and the smooth rolling contact by the traveling wheel 47 are accurate. Movement is realized. In addition, the color information of the color patch B measured by the colorimeter 31 is sent to a processing device (not shown) in this embodiment, and a correction value is calculated by comparing with the color information of the image displayed on the monitor. , Supplied to the printer driver of the inkjet printer 100 and reflected in the execution of subsequent recording.

  On the other hand, the color measuring device 31 that has finished the color measurement and has been located at the return position starts to move toward the home position by the reverse rotation of the carriage drive motor 54. When the colorimeter 31 reaches the home position, calibration is executed and the colorimeter 31 covers the upper surface of the white tile 36 to prevent dust and the like from adhering to the upper surface of the white tile 36. Subsequently, the pressing member drive motor 70 rotates in the reverse direction to bring the pressing member 34 into the retracted posture, and prepares for the next conveyance of the roll paper R or cut paper P.

[Other embodiments]
The recording apparatus according to the present invention is based on the configuration as described above, but it is of course possible to change or omit the partial configuration without departing from the gist of the present invention. For example, it is only the wind outlet portion that is disposed adjacent to the color measuring device, not the entire hot air drying device. That is, the heat source (heater) is arranged in a different place away from the color measuring device in the hot air drying device. Thereby, the influence of the heat on the colorimetric device and other peripheral parts can be greatly reduced.
