本発明はオフセット印刷機のインキ・キー制御器に関す
るものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an ink key controller for an offset printing press.
オフセット印刷機のインキの送り量は印刷紙の幅方向に
数十分割され独立して制御出来るインキ・キーの開度に
よって決定される。そして現在では印刷する各色の版の
絵柄から面積亭を計測し、当該絵柄面積率をもとに各分
割インキ・キーの開度を自動設定してその印刷に必要な
インキ量を供給している。The amount of ink fed in an offset printing press is determined by the opening degree of the ink key, which is divided into several tenths in the width direction of the printing paper and can be controlled independently. Currently, the area is measured from the pattern of each color plate to be printed, and the opening degree of each divided ink key is automatically set based on the pattern area ratio to supply the amount of ink necessary for printing. .
しかしながら、上記の絵柄面積率はそのままインキ・キ

ンキ・キー開度率Ｃ二変換されてインキ・キー開度は設
定される。However, the above pattern area ratio does not directly lead to the ink key opening ratio, and the ink key opening/closing M2' of the printed keyaki? It depends on the printing characteristics, type of ink, temperature, humidity, etc. For this purpose, it is generally possible to set a conversion function (conversion curve) in the ink key suppressor. As a result, the image area ratio data is converted into the ink key opening ratio C2, and the ink key opening degree is set.
そして変換関数を一度設定して絵柄面積率を入力すると
ただちにインキ・キー開度率は決定され設定されるが、
上記のように温度、湿度によっても開度率は左右され、
又、印刷物の内容、例えば人物像、風景画書＝よっても
その特徴を誇示することから、インキ使用量を更に微調
整する必要性力ｉ生じる。Once the conversion function is set and the image area ratio is input, the ink key opening ratio is immediately determined and set.
As mentioned above, the opening rate is also influenced by temperature and humidity.
Moreover, since the content of the printed matter, such as a portrait of a person or a landscape painting, is intended to show off its characteristics, it becomes necessary to further finely adjust the amount of ink used.
これに対してそのつど印刷物に応じて変換部なるため現
在では絵柄面積率データーにより変換してインキ・キー
開度を自動設定を行った後に、各分割インキ・キー開度
を手動により補正して適正なインキ量を供給している。On the other hand, since the conversion section needs to change depending on the print each time, currently, the ink and key opening are automatically set by converting the image area ratio data, and then each divided ink and key opening is manually corrected. Appropriate amount of ink is supplied.
このため、手動設定に対する煩わしさと時間消費がとも
なって好ましくない。Therefore, manual setting is troublesome and time consuming, which is not preferable.
本発明は各色数種類の変換関数をあらかじめ記憶素子に

とんど手動による補正を行う事なしに適正なインキ量を

Ｉ：したものである。In the present invention, several types of conversion functions for each color are stored in advance in a storage element, and the necessary number of conversions N can be selected with a simple operation according to the content or situation of the printed matter, thereby almost eliminating the need for manual correction. It is designed to supply an appropriate amount of ink to the printer, thereby eliminating the above-mentioned drawbacks.

出来る。Embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows a block diagram of the ink key control system of the present invention. In the conversion function creation section (4), each color is C: It is possible to create and store several types of conversion functions, and it is possible to prepare conversion functions that correspond to different patterns, etc.

表示される。In the conversion function setting section (5), the created function can be freely selected corresponding to the printing C2. Now, when printing C2, the magnetic card (1) containing the image area ratio data set for each color, such as image area ratio - ink key opening ratio, conversion function, desired for printing, is transferred to the magnetic card data reading device. Put it in. The data is read and converted into an ink key opening degree by a conversion function set in a conversion section (3), and a key opening command is inputted to a control section (6). The ink is detected by the signal from the opening position detection potentiometer (9).
The key opening/closing drive mode (8) rotates and the ink key is preset. The preset position of this ink key is indicated by digital and analog meters on the display (7).

である。That is, in the past, the conversion function was semi-fixed and only one type, but in the present invention, the conversion function can be freely selected from among the stored curves according to the printed matter. !
#- Since it hardly requires correction of settings, it is possible to go from trial printing to actual printing in a short time, and has the feature that it is possible to automatically print distinctive printed matter.
