Image Upscaling: A Detailed Guide for Beginners
If you're creating posters using Midjourney or other AI image generators, you may need to upscale your artwork before printing it. But what exactly is upscaling, and how do you know if your image is good enough for printing? ⓵ What is upscaling? An AI-generated image might look fantastic on your screen, but it may not contain enough pixels to look sharp when printed as a large poster. Upscaling increases the number of pixels in an image, making it more suitable for printing at larger sizes. There are two ways of doing this: - Normal resizing: Enlarges an image by estimating additional pixels from the existing ones. This doesn't add meaningful new detail and can leave the image looking blurry. - AI upscaling: Uses AI to estimate and recreate details, often producing cleaner edges and a sharper-looking image. AI upscaling can improve an image, but it isn't guaranteed to produce perfect results. ⓶ Forget about DPI. Focus on pixels. When preparing artwork for printing, you'll often hear that your image needs to be 300 DPI. But what does that actually mean, and is it really what you should be focusing on? First, let's understand three terms you'll come across: - Pixels: The tiny squares that make up a digital image. The dimensions of your image, such as 4000 × 6000 pixels, tell you how many pixels it contains. - PPI (Pixels Per Inch): The number of image pixels used per inch when printing. - DPI (Dots Per Inch): Technically refers to the tiny ink dots a printer produces. However, people often use DPI when they actually mean PPI. But here's the important part: Simply changing an image from 72 to 300 DPI or PPI, without resampling it, doesn't add more pixels or improve its quality. What matters is having enough pixels for the size you want to print, along with good-quality artwork. ⓷ How many pixels do I need? The larger your poster, the more pixels you'll generally need to maintain a sharp image. Here's a handy reference showing suggested pixel dimensions for high-quality printing across common poster sizes:
