What does dpi stand for in printing

This is a bit more simple to answer as it basically refers to a physical resolution versus a digital resolution. Essentially, DPI is a measurement of the amount of dots per inch produced by a physical printer in any given inch squared, and PPI pixels per inch is a measurement of the number of pixels per inch square on a screen. In this scenario, your prints could look blockier on a screen and smoother when printed.

Essentially, there is the same amount of pixels on the screen, but because one monitor is bigger, the pixels are bigger and therefore there are fewer in an inch square.

This is not the case with DPI though as if you design to DPI, no matter the pixel resolution, the printer will know to convert your file to have dots per inch of print. DPI, or dots per inch, are actually like microscopic polka dots, each with space in between each one so is less precise but often look softer or smoother.

Essentially, each pixel can be a mixture of red, green and blue to make the individual pixel appear as any colour you want.

To make the colour, on a microscopic layer, all four colours are laid over each other in a mesh-like pattern of different amounts to create colour. So, technically, there is no standard for print like there are for PC monitors or TVs. The resolution of a digital photo is its pixels , generally expressed as Megapixels or Mp - also simple arithmetic, the horizonal pixel dimension of a photo multiplied by its vertical pixel dimension.

A digital photo is made up simply of pixels - that's all a digital photo, or any other type of bitmapped image, is. See the What is a Digital Photo page for all those details. To get a PPI number for any digital photo you need to know the intended print size.

A request for a ppi or dpi image is absolutely meaningless in itself - the request has to be accompanied by an intended print size. A meaningful request is for a digital image that will be ppi when printed to 8" x 10" or any other physical dimension. With that information you can now calculate the PPI of your digital image when printed to that size of paper.

In our specific example of ppi for an 8" x 10" print, if you had a digital photo that was say 8 Mp in size it might have pixel dimensions of x pixels those exact numbers will depend on the camera manufacturer.

Divide those dimensions by your print size and you'll get They are different because the aspect ratio length to width is different a common problem - so the smaller number applies, your digital photo will print to ppi on 8" x 10" paper with a bit of cropping. It would meet the request for ppi at 8" x 10" more pixels are okay. We could also look at it the other way - if the request is for a photo that will print to ppi on 8" x 10" paper, we can multiply ppi by those dimensions and we'll get x pixels or 7.

So, to meet the request, you'll need a digital photo that is at least 7. In fact the simplest and best request for a digital photo would be a high quality photo see the What is a High Resolution Photo section below for a definition of high quality , at X Megapixels, in a specified file type. That's it. Internal office communication can be reproduced with a low resolution, but anything used outside the office should be higher than dpi. After all, the printing quality needs to represent your business.

Medium-resolution images have between dpidpi. The industry standard for quality photographs and image is typically dpi. For businesses, producing an external document like a brochure, a booklet, or a flyer requires dpi. You might be able to get away with dpi if you are less concerned with the quality and resolution of the printing.

Any marketing material or collateral produced should be, at a minimum, dpi. Booklets, pamphlets, reports, and sales sheets should all be printed at dpidpi or more.

Most businesses consider dpi and higher to be a high-resolution image or print. High-resolution images require more memory to store and can take longer to scan. Storing high-resolution images can quickly fill a hard drive or server.
