DEVICE FOR INPUTTING DOT AREA PER CENT

摘要

PURPOSE:To determine easily at which dot area per cent printing is to be performed by comparing a conversion table for color information-dot area per cent and the information on the respective colors of an object to be measured, selecting the color information most approximate to the color information of the object to be measured and inputting the combination of the dot area rate corresponding to the same to an external device. CONSTITUTION:A conversion table for color-information-dot area per cent with the combination of color information and the dot area per cent corresponding to the color information on plural colors of color separating plates is preliminarily stored in a storage means 10, and the data in the color information determined by a means 20 for measuring the color of the object to be measured is once stored in a storage means 30. A means 40 for selecting the color information compares the color information of the conversion table for the color information-dot area per cent and the color information of the object to be measured and selects the color information most approximate to the color information of the object to be measured from the former. The combination of the dot area corresponding to the selected color information in the above-mentioned way is inputted to an external device by a means 50 for inputting the dot area per cent. The dot area per cent of each color is easily inputted to the external device in the case of expressing the colors of the object to be measured by printing ink in the above- mentioned manner.
