在打印机的技术发展史上,DPI(分辨率)一直是衡量打印机的打印品质的一个重要指标。传统的提高打印品质的方法是提高打印机的DPI。所谓打印机的分辨率是指喷墨墨头能够在每英寸纸上精确喷出的点数。比如说,一个600DPI的喷墨机的喷头,最多能在每一平方英寸纸上打印出600×600=360000个点。显然,为了组成准确、精美的图案文字,这些点不可能都是分离或相切的,总是有一些重叠。因而,重叠的、多余的墨水就会使该处的颜色过于饱和,我们可能
In the history of printer technology, DPI (resolution) has been a measure of the printer’s print quality is an important indicator. The traditional way to improve print quality is to increase the printer’s DPI. The so-called printer resolution refers to the inkjet head can be precise points per inch of paper. For example, a 600 DPI inkjet printhead can print 600 x 600 = 360,000 dots per square inch of paper. Obviously, in order to form accurate and beautiful pictorial, these points can not be separated or tangent, there is always some overlap. Thus, overlapping, excess ink will make the color of the place too saturated, we may
