In the above inkjet recording apparatus, as shown in the second wA, a recording medium 11 having good ink absorption property is used so that most of the ink particles adhering to the recording medium INC are absorbed and fixed inside the recording medium 11. However, in general, recording media with good ink absorption properties tend to allow ink to smudge on the surface.
The spread of the dots tends to become larger. Therefore, it is difficult to obtain a high-resolution recording of a single kanji figure, etc.The purpose of the present invention is to provide an inkjet recording device with a platen heating device. To provide a device that quickly fixes high-resolution recording results and enables high-resolution recording.

Generally, in an inkjet recording device fjjI, the ink adhering to the recording medium is determined by ink permeation into the recording medium and evaporation of the ink solvent into the air. The fixation time of ink depends on the ink permeation speed and ink evaporation speed of the recording medium. Therefore, recording media with high ink permeation speed will have lower recording resolution. Conversely, recording that can perform high-resolution recording The penetration speed of ink into the medium is slow, and ink fixation progresses mainly through evaporation of the ink solvent. Therefore, when using a recording medium that can perform high resolution recording with conventional inkjet recording packaging, It takes a fairly long time for the ink to fix. Therefore, in the present invention, as shown in FIG. Then, the heating device 12 is installed to heat the platen 1f. Note that the heating resistor used in the heating device [12] can be a nichrome-wrapped heater, a ceramic heater, a posistar, etc. In this example, it has a size of 30 mm x 200 mm, and a 12W
(Resistance: 300Ω, 60V, 0.2A) Heating device #I
to heat platen 1 and heat platen IV.
The ink printed on the recording medium 11 was dried and fixed on both sides of the ink.

The grating heated by the heating device [112] rotates and contacts the recording medium 11, heats the recording medium 11, and prints on the print head 7, thereby promoting the evaporation of the ink solvent. In addition, since inkjet printing is non-impact, the material of platen 1 can be freely selected, and there is no problem even if it touches a metal surface. , the key to safety is the recording device fl.
It is desirable to have a function to start the klkb operation after the IK recording medium 1.1 is set.Furthermore, as shown in Figure #g4, the temperature control system of the platen heating I & amount 12 of the present invention is installed. The temperature of the recording medium 11 is detected by the detector 13, and the platen heating device fI/112 is controlled by the temperature control circuit 14 through the feedback system to maintain the desired temperature. 1 Using a Latin heating system, we investigated the relationship between the ink fixing time by indirectly changing the recording medium temperature. Figure 5 shows the relationship between the recording medium temperature and the ink fixing time. The axis shows the fixing time of one dot of ink attached to the recording medium, and the horizontal axis shows the temperature of the recording medium. Experiments were carried out on three types of recording media. By increasing the recording medium temperature, the ink fixing time can be changed.・The average ink fixation time for recording media at room temperature was about 20 minutes for alphanumeric characters, and about 50 minutes for solid paper. degree[%
The average time for Bettahi was about 60 seconds 0Here, compared to recording medium ■, the ink was absorbed more easily into the recording medium, and the dots on the surface were more spread out and the smudge was larger. In this case, the ink was almost perfectly circular and the dot spread was about 1/2 of the width of the recording medium ■, making it possible to record high-resolution characters such as kanji. ・When the temperature of the recording medium was increased to 70°C, 1 ink was fixed. Time #i1 dot is less than 10 seconds9
Yes, the recording medium is a recording medium! Although the dots were more spread out, the ink fixation time was shorter than that of the recording medium ■.For this recording medium, a temperature of 60°C was sufficient to make the ink fixation time less than 10 seconds.As mentioned above, The ink fixation time on the recording medium depends on the type of recording medium used, and also depends on the platen heating device fIj#I
Also, as shown in Figure 6, the dot diameter on the recording medium ■ remained almost constant even when the temperature of the recording medium increased. As a result of recording with the medium temperature set at 70°C, recording medium 1. In both I and IO cases, the same IC+ print quality as when recording at room temperature was obtained.The required ink fixation time varies depending on the structure of the recording device fif, and in the case of monochromatic or comparative color recording, A short fixing time is required. The recording medium is selected according to these requests, and the recording medium ! It is desirable to change the set value once.・The operator may change the nil set value depending on the characteristics of the recording medium.
◎The present invention has been explained using the above embodiments, but according to the invention, by providing a device that heats the platen in close proximity to the platen, it is possible to achieve high resolution without deteriorating the printing quality. The I! recording result can be fixed quickly, and the release rate is higher than that of conventional inkjet recording devices. The effect of e-recording is huge.
