It is default in the industry that is based on the assumption it will give a photo quality image. It is key to understand that displaying the image at 300ppi is arbitrary. When I open the image in Photoshop it will automatically open at 300ppi, which will give me a printed image of 43.89cm by 29.26cm. Now everyone, (including the manufactures) call this number (18 mega pixels) the resolution, but it isn’t, it is in fact the image size measured in pixels. It is these 18 million pixels that are important. At 5184 x 3456 the photo has 17,915,904 pixels in total, which is close to 18 million, which is no coincidence because the specification of my camera is 18 mega pixels (where 1 mega pixel is 1 million pixels). On the highest quality setting my Canon 60D digital camera records a digital image that is 5184 pixels in width and 3456 pixels in height. But let’s ignore dpi for now, we’ll get back to it later in the article. More specifically, it is the number of dots of ink per inch the printer applies to the paper. But there is a big difference.ĭpi (dots per inch) is typically used in reference to printing. #Image area of final print software#It is often confused with dpi and many people (printing and visualisation companies included) and software applications use them interchangeably. Ppi (pixels per inch) is the industry standard term when referring to how digital images are displayed on a digital screen. ![]() A digital image is formed of thousands or millions of pixels, each a different colour (typically red, blue or green) and brightness value.Ī close up view showing the thousands of pixels that make up one of our images In digital imaging a pixel is a single point on a computer screen, tablet, smartphone or any other digital display. The word pixel is a combination of pix (picture) and el (element). Pixels are the building blocks of any digital image, whether it’s a render of a 3d model or a photo taken with a digital camera. ![]() Pixels vs dots – two types of resolutionĪ lot of people say dpi (dots per inch) when they actually mean ppi (pixels per inch), and in our experience even print companies struggle when it comes to recommending the size and resolution of a digital image for print. ![]() It also explains why the total number of pixels in an image is the most important thing when it comes to determining the size at which you can print an image. This post explains how ppi and dpi differ, why it matters, and why rendering an image at 225ppi (or lower) is fine for most print jobs. If you’ve wondered what it actually means, read on. Many of our clients, and their printing companies, ask that our rendered images have a resolution of 300dpi without really knowing what this means in terms of digital images.
