英语翻译
the number of colors that a monitor and graphics card can display is referred to as color depth or "bit depth".most pcs have the capability to display millions of colors.when set at 24-bit color depth(sometimes called"true color")your pc can display more than 16 million colors--and produce what are considered to be photographic-quality image.windows allows you to select resolution and color depth.most desktop owners choose 24-bit color at 1024*768 resolution.
Printers
printer technologies popularly include ink jet,laster,and dot matrix recently.these printers differ in resolution and speed,which affect the print quality and price.
resolution.the quality or sharpness of printed images and text depends on the printer'sresolution--the density of the gridwork of dots that create an image.printer resolution is measured by the number of dots it can print per linear inch,abbreviated as dpi.at normal reading distance,a resolution of about 900 dots per inch appears solid to the human eye,but a close examination of color sections will reveal a dot pattern.although 900 dpi might be considered sufficient for some magazines,expensive coffee-table books are typically produced on printers with 2400 dpi or higher.
显示器和显卡可以显示的颜色数量被称为色彩深度或者“位深度”(这个两个专用名词是直译的,不明白).多数计算机有显示上百万种颜色的能力.如果设置为24位色彩深度(有时候被称为真彩色),你的电脑就可以显示不只1600万种颜色,并且生成可以被当作像相片一样质量的图像.Windows允许你选择分辨率和色彩深度.大部分用户选择24位色和1024*768的分辨率.
打印机
打印机技术通常包括墨盒(喷墨)打印,激光打印(laser输错了~),以及最近的点阵打印.这些打印机区别在分辨率和打印速度.这些因素会影响打印的质量和价格.
分辨率
打印出来的图像和文字的质量或者清晰度取决于打印机的分辨率————组成图像的点阵的密度.打印机分辨率一般由每单位英寸可以打印的点数测算,缩写为dpi.在正常阅读距离,大约900dpi的分辨率在人眼看来很清楚,但是近距离检查颜色选择会发现点的图案.尽管900dpi可能对于一些杂志已经足够了,但昂贵的咖啡桌上的休闲书籍通常用2400dpi甚至更高的分辨率打印.
