The net effect of all this can be summed up very succinctly: Any high-quality image with a decent enough resolution to work on a book page will work at any print size without any resampling needed. Since Lightroom first launched 11 years ago, Scott Kelby’s The Adobe Photoshop Lightroom Book for Digital Photographers has been the world’s 1 top-selling Lightroom book (it has been translated into dozens of different languages), and in this latest version for Lightroom Classic CC, Scott did his biggest update ever, sharing all his latest techniques, insights, and invaluable tips using. For bigger prints, you will step back to see it from a greater distance, and ppi requirement drops rapidly. In reality, 300 ppi is a technical/theoretical upper limit for small images seen from arm's length, and printed using a standard halftone screen frequency of 150 lines per inch.Įven 300 ppi at that size is probably above what the eye can resolve. Which, unfortunately, has led to the widespread misunderstanding that printing in any shape or form always requires 300 ppi at any size. If you send out to commercial offset book/magazine print, the requirement will almost always be 300 ppi at the specified size. It tells you how big you can print, or how many pixels you need for your intended use/size. In the latter case, you want to keep an eye on effective ppi.Įither way, it will still be useful as a guide to yourself. You can scale in the printer driver, and you can scale in InDesign. Let's call it a ppi intent, based on an intended size.
