A thermal transfer recording method that includes a process to remove ink remaining on the base film.
本発明は粗面紙に低コストで情報の記録を行う熱転写記

ンパクトプリンタとノンインパクトプリンタとに大別さ
れ、各種の印字方法が実用化されている。Printers record input information or output information to information processing devices, and are essential for information processing.They are broadly classified into impact printers and non-impact printers, and various printing methods have been put into practical use. .

意の抵抗体を発熱させ、インクリボンのインクを記録紙
に転写して印字を行うものである。Here, a thermal printer (hereinafter referred to as a thermal printer) is a typical non-impact printer that uses a thermal recording head using a large number of thin film resistors made of tantalum nitride (TazN) l+-chromium (Ni-Cr), etc. A printing section (hereinafter referred to as a thermal head) is formed, which generates heat in an arbitrary resistor in response to a signal and transfers ink from an ink ribbon onto recording paper to perform printing.

用紙(ThermalTransfer Paper略
称TTP) Lか使えないと云う問題がある。Such thermal printers do not generate noise and are capable of developing,
Although it has the characteristic that it does not require extensive processing for fixing, there are certain limits to the power supplied to the thermal head and the pressure of the roller that presses the recording paper against the thermal head, so it is necessary to print thin and smooth prints to obtain high quality prints. There is a problem that you cannot use thermal transfer paper (abbreviated as TTP).
そこで、普通紙特にゼログラフィ用紙、ボンド紙のよう
に厚い粗面紙(以下通称のラフペーパ)を使用した場合
でも高品質の印字ができる熱転写方式の実用化が要望さ
れている。Therefore, there is a demand for the practical application of a thermal transfer method that can print with high quality even when using plain paper, particularly xerography paper, and thick rough paper (hereinafter commonly referred to as rough paper) such as bond paper.
熱転写方式を用い、従来の印字速度を保ちながらラフペ
ーパに印字を行うには現像工程と定着工程とを分離して
行う必要がある。In order to print on rough paper using a thermal transfer method while maintaining the conventional printing speed, it is necessary to separate the development process and the fixing process.

圧ローラの圧力が緩和され、また熱量が不足するため、
インクの熱転写量は充分ではなく、そのために良質の印
字を行うことができない。That is, during printing, the temperature of the heating resistor that makes up the thermal head rises to about 400 degrees Celsius by energizing it for about l+nm seconds, but if the paper is thick (and porous), the pressure of the pressure roller is relaxed, and Due to lack of heat,
The amount of thermally transferred ink is not sufficient, and therefore high-quality printing cannot be performed.
これを解決して良好な印字を行うには、ポリエステルフ
ィルムのように薄く且つ緻密なフィルムを基材として使
用してインク像を作り、これを高い熱エネルギーと圧力
を加えてラフペーパーに転写するようにすればよい。To solve this problem and achieve good printing, an ink image is created using a thin and dense film such as polyester film as a base material, and then transferred to rough paper by applying high heat energy and pressure. Just do it like this.
これに類似した方式については既に他社より次のような
出願がなされている。The following applications have already been filed by other companies for systems similar to this.
