DPI是指每英寸可打印的点数。如300 DPI,即表示打印输出的每一个点为1/300英寸或每英寸可打印300个点。DPI 值越高,打印输出的效果越精细,相应的输出时间也就越长.通常,我们都使用dpi来作为扫描器和打印机的解析度单位,数值越高表示解析度越高。目前,市面上出售扫描器的光学解析度主要有600×1200 dpi和1200×2...
What started at 100x100 dots per inch (DPI) quickly escalated to 300x300, then 600x600, and finally the current industry standard of 1200x1200 DPI. Back then, the meaning of these values was clearly understandable; even the units made perfect sense. Unfortunately, things get more complicated ...
This is where most of the confusion exists because PPI and DPI are often used interchangeably to mean the same thing, which is wrong!DPI does not apply to digital images!As I said earlier, DPI is a physical property of a printer, not the digital image. When talking about print size, PP...
But what exactly does it mean and what are the differences? DPI means dots per inch. And is the size that indicates how many printed dots (dots) of ink per square inch are used when printing an image on a printer. PPI means pixels per inch. This refers to the number of pixels used...

Video does not use dpi. When I say Video, I don't just mean movies, I mean anything on the monitor viewing screen, computer or TV. The video screen size is dimensioned in pixels, and the image is dimensioned in pixels, and the pixels are simply shown directly — without any concept...
We talked earlier about DPI and PPI. It is both used to describe the resolution of an image. But what exactly does it mean and what are the differences? DPI means dots per inch. And is the size that indicates how many printed dots (dots) of ink per square inch are used when printing...
Good to know: the difference between DPI and PPI We talked earlier about DPI and PPI. It is both used to describe the resolution of an image. But what exactly does it mean and what are the differences? DPI means dots per inch. And is the size that indicates how many printed dots (do...
Higher DPI can mean higher resolution, but dot sizes vary by printer There is no standard dot size or shape, so higher DPI does not always equate to a higher quality print. One manufacturer’s dots might look as good at 1200 DPI as another manufacturer’s dots do at 700 DPI. Books and...
Notice that it does not matter now what original scan resolution produced this 1200 pixel image. Perhaps the original scan was an 8 inch original scanned at 150 dpi. Or maybe 1 inch of film scanned at 1200 dpi. Or ½ inch of film at 2400 dpi. It simply doesn't matter now, this im...
