六十六、如何正确选择扫描仪?目前纸质档案数字化主要使用以下四种扫描仪,它们分别有不同的适用范围:一是平板式扫描仪(见图1)。扫描分辨率在100—2400dpi之间,色彩位数从24位到48位。扫描幅面一般为A4或A3纸张。它的优点是扫描图像清晰,色彩逼真,不易损坏纸张。缺点是扫描速度比较慢,图像处理功能比较弱。适用于纸张状况较差,如纸张过薄、过厚、过软或破碎的档案。
Sixty-six, how to choose the right scanner? At present, the digital paper archives mainly use the following four kinds of scanners, they have different scope of application: First, the flatbed scanner (see Figure 1). Scanning resolution between 100-2400dpi, color bits from 24 to 48. Scanning format is generally A4 or A3 paper. Its advantage is clear image scanning, vivid colors, difficult to damage the paper. The disadvantage is the scanning speed is slower, the image processing function is relatively weak. Suitable for poor paper conditions, such as paper is too thin, too thick, too soft or broken files.
