本文旨在介紹印刷水槽液pH值測試量測不確定度之估評。在文中,簡述水槽液pH值對平版印刷的影響,並且大篇幅地以實例敘述平版印刷水槽液之量測不確定度之過程,其內容包含量測不確定度誤差來源分析、估評方法、組合量測不確定度、擴充不確定度及擴充係數等。
The paper is aimed to introduce the estimation of the measurement uncertainty of pH measurement for lithographic fountain solution. In the paper, besides briefly describing about the effects of lithographic fountain solution, the authors apply an example to explain the process of estimating the measurement uncertainty of pH measurement for lithographic fountain solution. The process includes the analyses of sources of uncertainty, the methods of estimating, combined standard uncertainty, expanded uncertainty and coverage factor, etc.
