在平常扫描工作中,经常遇到如书法题词、条码、图标类的原稿需要作为位图来处理。各种扫描程序中都设置了位图模式,但若直接用位图模式扫描,效果很不理想。经过一段时间的实践,我总结出如下方法。 1 以灰度模式将原稿扫描成高分辨率的灰度图,为保证质量,图像分辨率不能低于600dpi。 2 进入Photoshop中,采用亮度/对比度,色阶等命令调整图像,一般用色阶(Level)命令。调出层次(Level)
In the usual scanning work, often encounter such as calligraphy inscriptions, bar codes, icon class manuscripts need to be handled as a bitmap. Bitmap mode is set in various scanning programs, but if you scan directly in bitmap mode, the effect is not very satisfactory. After a period of practice, I concluded the following method. 1 The original is scanned in grayscale into a high-resolution grayscale image. To ensure quality, the image resolution can not be lower than 600 dpi. 2 into Photoshop, the use of brightness / contrast, color levels and other commands to adjust the image, the general level (Level) command. Transfer level (Level)
