Description
【発明の詳細な説明】 〔産業上の利用分野〕 本発明はインクジェットプリンタ番こ関する。[Detailed description of the invention] [Industrial application field] The present invention relates to inkjet printers.
インクジェットプリンタは、その印字音の静粛さから、
広く事務処理に利用されるしこ至った。しかしながら、
液体インクを用いた装置にあっては、インクの速乾性、
定着性などの点でいまだ完全なる普通紙対応がとれてい
ない。Inkjet printers are known for their quiet printing noise.
It has become widely used for office processing. however,
For devices using liquid ink, the quick drying of the ink,
It is not yet fully compatible with plain paper in terms of fixability, etc.
本発明は液体インクを用いたインクジェットプリンタに
おいても、インクの速乾性を確保し、専用紙によらず高
い印字品質を実現することを目的とした。An object of the present invention is to ensure quick drying of the ink even in an inkjet printer using liquid ink, and to achieve high print quality regardless of special paper.
本発明は、液体インクを中性紙上に印字した際などに生

ー、３は４００Ｗ（７）紫外線ランプである。This drum 1 has a rotating shaft driven by a DC servo motor and rotates at a constant speed in the direction of arrow A. In addition, a pressure roller 6 made of hard rubber is provided, and a paper feed roller 8 is configured to feed the printing paper 9 in the direction of arrow B. On the other hand, the head carriage 5 moves in the long side direction of the drum and is conveyed by a belt driven by a step motor. This is shown in FIG. The head carriage 5 moves in the direction of the arrow along a guide shaft 12.13, and the head 4 is fixed thereto. 1
4 is a drive belt. Furthermore, 2 is a cleaning roller, and 3 is a 400W (7) ultraviolet lamp.

た状態で印刷用紙９に圧力定着さ庇る。The head 4 is a drop-on-demand type inkjet head that can print by discharging liquid ink with a viscosity of 10 to 12 mPa-5 at a response speed of 1.5 K]4z, and has two heads each having a 12-nozzle configuration. Dot matrix printing of 24 vertical dots can be performed by overlapping the dots. In this case, the ink used in this example consisted of 30% UV-curable prepolymer, 60% monomer, and 6% photoinitiator.
, a coloring agent of 4% and a viscosity of 11 mPa was used. At this time, when irradiating light from 3 cm above the paper surface with a 400 W ultraviolet lamp, it took about 30 seconds to create a diameter of 10 μm.
The ink droplets were completely solidified. Based on this, in this embodiment, the printing position on the glass drum 1 is
The drum rotation speed was controlled so that the time required to transport the drum to the position was 15 seconds. Due to the peeling, the ink droplets printed on the glass drum 1 are irradiated with ultraviolet rays while the drum is rotating, and curing is accelerated, and the ink droplets are fixed under pressure to the printing paper 9 in a state of extremely high viscosity.

着するものである。FIG. 2 is a block diagram of another embodiment. Here, 15 is an aluminum drum, and 10 is a 600W heater. In this example, the liquid ink is made to have a high viscosity by making use of the property that curing of the ink is accelerated by heating, and then pressure fixing is performed. It is something.
印刷用紙は、紙の吸湿性、表面のＩ） Ｈなどにより、
印字ドツトににじみを発生する場合が有る。Printing paper has different characteristics due to its hygroscopicity, surface I)H, etc.
Bleeding may occur on printed dots.
これは高粘度のインクを使用することで解決できるが、
通常のインクジェットヘッドでは粘度数十から数百ｍＰ
ａ＠Ｓのインクの印字はできない。This can be solved by using high viscosity ink, but
Normal inkjet heads have a viscosity of several tens to several hundred mP.
It is not possible to print with a@S ink.

ににじみを生じないプリンタの構成ができた。In contrast, in the present invention, by setting a time lag of several seconds to several seconds between printing and fixing, the ink is fixed after it has cured, so the ink viscosity during printing can be lowered to around 10 mPa-5. . As a result, a conventional inkjet head can be used, and a printer configuration has been created that does not reduce responsiveness (and does not cause smearing in printing).
