When you’re putting together your school yearbook, image resolution might seem like a small detail, but trust us, it makes a big difference in how your pages turn out. Crisp, clear photos help your book look polished and professional, and make sure those memories shine.
What Is Image Resolution?
Image resolution is all about how much detail a photo holds. It’s measured in pixels per inch (ppi). For printing, you’ll want your images to be 300 ppi, whether they’re in colour or black and white. Anything lower (especially under 200 ppi) can look blurry or pixelated, and that’s not what you want in your final book.
Actual vs. Effective Resolution
There are two kinds of resolution to keep in mind:
- Actual resolution is what your image starts with, like when you open it in Photoshop.
- Effective resolution is what happens after you resize it in your layout software (like InDesign).
In ConnectMe, the image library displays dimensions based on 300dpi. When images are placed into DesignIt, they cannot be resized beyond these dimensions.
If you shrink an image in InDesign, the resolution goes up. If you stretch it bigger, the resolution drops. That’s why it’s important to check how your images are sized in your layout…not just how they look on screen.
How to Check Resolution in InDesign
InDesign gives you a couple of easy ways to check resolution:
- Use the Preflight tool to scan your whole document. It’ll catch any images that don’t meet the recommended resolution.
- Want to check just one image? Open the Info palette and turn on “Show/Hide Link Information” to see all the details.
Bonus Tip: Watch Your Colour Profiles
While you’re checking resolution, take a peek at your colour profiles too. InDesign’s Info palette shows the document’s working space…not the image’s embedded profile. To make sure everything matches, go to Edit > Assign Profiles and set the CMYK profile to match your press settings.
Common Mistakes to Avoid
Even seasoned designers slip up sometimes. Here are a few things to watch out for:
- Using web images: These are usually 72 ppi…fine for screens, but not for print.
- Enlarging small images: Stretching a low-res image might make it fit, but it’ll look fuzzy in print.
- Ignoring effective resolution: Don’t just check the original resolution, see how it changes when you resize.
- Skipping the preflight check: It’s there to help you catch issues before they hit the press.
- Mismatched colour profiles: If your document and images use different profiles, colours might shift when printed.
Image resolution might sound technical, but it’s one of the most important steps in getting your yearbook print ready. Taking a few minutes to check and adjust your images means your photos will pop, your colours will stay true, and your classmates will love flipping through every page.
