It's also relevant to understand what Sub-Pixels are:. When you use too much ink, the print job will be slow. You should be changing your printers setting to a lower DPI to save the ink and make the print job faster; you will recognise a difference in the quality of course.
Printers create a "print" by spraying little droplets of ink on the paper. It takes many dots to form one pixel for the image. The layout of the ink droplets is all taken care of by the internal software of your printer.
Instead, it is better to recreate your image by sputtering out minute dots consisting of a blend of different colours Cyan, Magenta, Yellow and Key black , which in-cooperate to generate hues by the decreasing colour model. In the end, DPI measures the density of the space between the dots. The unit resolution reflects dimensions of width x height and is the pixel attribute and can be used for any image on a digital medium or in print form. Higher DPI means high resolution and no resolution does not indicate the size.
They are different terms altogether. There is always a tiff about more the resolution, images are to be bigger, but that is not the case. They're different words. More resolution is often a slight argument, pictures are larger, but that is not necessarily the case. The regular resolution consists of dpi.
Inkjet printers produce a resolution around to DPI, while laser printers produce images anywhere from to 2, DPI. There is no standard dot size or shape, so higher DPI does not always equate to a higher quality print. Ask the printshop or consult the printer specifications to find the appropriate DPI for your project. Knowing how to use PPI will empower you to produce high quality images every time. And knowing how to navigate DPI will help you to effectively communicate with printing machines and professionals in the printing industry.
Unless you are a printer, your main focus will be on PPI. But it is important to understand the process of physical printing if your work requires it on a regular basis. In the end, even the best design can be ruined by a poor image resolution. Check out this article on graphic design basics for more design knowledge.

Get a design. PPI resolution — What PPI means PPI, or pixels per inch , refers both to the fixed number of pixels that a screen can display and the density of pixels within a digital image. Each pixel is made up of RGB subpixels. PPI, or pixel density, describes the amount of detail in an image based on the concentration of pixels.
Part of the confusion between the two terms stems from the fact that many people who use them are lazy and tend to use the terms interchangeably.
The simplest way of thinking about them is that one is digital ppi and represents what you see on the computer screen and the other is physical dpi for example, how an image appears when you print it out on a piece of paper. Everyone has heard the word pixel, but not everyone knows what it stands for.
A pixel refers to a picture element, which is the smallest physical element of digital display that the eye can discern. This is what you see when you zoom in as close as you can on your computer. Therefore, even though pixels are represented on a computer screen, they are a physically fixed size.
The number of pixels which you have on your computer screen is fixed. There is no special setting which you can access and then change the number of pixels displayed on your computer. So, what happens when you try to take an image from the computer screen and create a physical copy. PPI is not really important for web images because your monitor determines the pixel density. DPI dots per inch refers to the number of printed dots inside one inch of an image that is printed. The size of the image means more DPI is required.
Working with printers you typically only have 3 or 4 colors. Those colors have to combine to fake more than 65 thousand colors of ink dots that digital displays can display.
How do they do it? Up close you see something similar to the golf ball picture using pixels, only each dot is made up of yellow, cyan, magenta, and black. Just as you see all the dots in this half-tone photo you would see all the dots from an inkjet with a magnifying glass.
As you back away from each you no longer see the dots but instead, you see the photograph as a smooth composition. Take a few steps away from your computer to see what I mean. The higher DPI ink means picture elements are clearer and you can avoid a pixelated image. Remember the more dots per inch DPI the better the image quality. When your image size is larger and needs to be printed, the printer uses DPI dots per inch to produce the final product.
There is no standard for print size or dot shape. So a higher DPI does not always mean a better print. The best advice is to ask your print shop for help when choosing the right DPI for your printing needs. They can be used interchangeably when you are avoiding low resolution for your digital screen or images.
