Before rushing off to buy that premium photo paper so you can have your digital photos in hand, there are a few things to know when preparing for a digital print. It can be as simple as upload and print. But, if you want the maximum quality, clearest resolution, and the most vibrant and true colors, follow these tips used by professional photographers and graphic artists every time they print.
You may have seen two different acronyms, PPI and DPI. Most people use them interchangeably believing that they mean the same thing. Although they are similar they actually do find different stages of the photography or printing process.
PPI simply means pixels per inch. In other words, this is the total number of pixels in a certain area captured by your camera's sensor when you take the picture. This defines how much digital information is actually contained for that image. You can enlarge the picture or increase the DPI, however the picture which has become grainy or blotchy which is known as pixelation.
Images become pixelated when there are not enough pixels in the image to accurately represent every color and line. Therefore, you get a lot she mosaic appearance. You can tell when the resolution is too low because lines are not as smooth as they should be and colors can appear blotchy.
This is where camera quality matters because the more pixels in the photo, the more flexibility you have with the size and resolution. The better the input, the better the outcome will be.
Dpi is actually a component of the printing process. It means dots per inch and refers to offset printing. If you have examined a newspaper or magazine up close, you have probably noticed a series of tiny dots that blend together to form the image.
