Vocabulary

dpi - Dpi, or dots per inch, is same to ppi, pixels per in. Dpi just indicates how masses dots (pixels on peak) will be written. More dots per in process more small point in the written photo, so peak publications force digital imagery to be blessed at 300 dpi. But be careful!

JPEGs are "lossy," which money all event the logo is emended and saved, several data is wasted so the report can be crushed. A JPEG directory that has been redeemed umteen nowadays starts to get pixelated "artifacts" and the picture will appearance shadowy.
