平面圖像數位化之品質控制因素分析

An Analysis of Quality Control Parameter for Digitalizing the 2-D Image

電腦科技的發展改變了工業生產結構，創造人類新的物質生活文明。二十世紀末電腦科技為圖文傳播技術帶來了新趨勢；平面圖像複製的過程中廣泛地使用了電腦，已徹底改變了平版印刷作業流程。掃描機是平面圖像數位化的裝置，隨著資訊科技的發展，掃描機的功能不斷推陳出新，操作方法也愈來愈簡易。我們應瞭解掃描機的功能特性才能以最少的投資獲得最佳的複製品質。平面圖像數位化是印前作業的重要工作項目，因此，平面圖像數位化的品質控制是達成最佳印刷品質的關鍵。本文主要目的在分析平面影像數位化需控制之品質因素。當我們充份瞭解電腦設備之功能並學習印前圖像數位化的知識，就能利用資訊科技提昇圖文複製的品質。

The latest development of computer technology has changed the industrial structure which the brand new civilization of material life for human; As a result, It has brought new trends for Graphic Art Communication accordingly; It has fully changed the process flow of lithographic printing while computer has been wildly used for 2-D image. The scanner is used to convert the 2-D image to digital data, accompanying with development of Information Technology, the scanner is always functional better but also operated easier. It is necessary to get the best reproduction quality with the most economical investment, by mastering the functional characteristics and operational method of the scanner. The parameter for the Quality Control of digitalizing the 2-D image is the key-point to optimize the image reproduction quality because digitalizing the 2-D image is playing an important role for the pre-press process. The quality of Graphic Arts can be improved take advantage of the computer technology if the parameters were fully controlled.
