摘　　要：测试图样在数字文献转换缩微品过程中具有重要作用。文章概述了数字文献转换缩微品技术的发展情况,详细解读了国家标准中关于测试图样的设计原则、技术要求和测试方法,以及相关实践工作中测试标板的制作,发现测试图样主要包含画面变形性测试、解像力测试、密度或色彩还原性测试三要素,并从设计的多维度考量、选择标准的细化、技术要求的全面性与适用性、应用步骤的系统性、更新与管理机制的标准化、操作人员的能力提升、监督与评估机制的完善等方面提出了测试图样设计的建议。本研究对于提高数字文献转换缩微品行业的规范化水平、促进测试标准的完善具有重要意义。Test patterns play a crucial role in the process of converting digital documents into microforms.This article provides an overview of the development of digital document conversion microform technology and offers a detailed interpretation of the national standards regarding the design principles,technical requirements,and testing methods for test patterns.The study also addresses the production of test boards in related practical applications.It identifies three key elements of test patterns:image distortion testing,resolution testing,and density or color reproduction testing.The article proposes suggestions for test pattern design from multiple dimensions,including the refinement of selection criteria,comprehensiveness and applicability of technical requirements,systematic application procedures,standardization of updating and management mechanisms,enhancement of operator skills,and the improvement of supervision and evaluation mechanisms.This research is of significant importance for enhancing the standardization of the digital document conversion microform industry and promoting the improvement of testing standards.
