Resolution Warnings

Yearbooks are usually rendered and printed at 300 dpi. Your publishing company has specified resolution warning levels to ensure that content placed on your pages will print well.

Images have a resolution measured in the number of pixels across the length and width. For example, most yearbook portrait images have a 640 pixel wide x 800 pixel tall resolution.  When an image is added to your canvas and sized to a particular dimension on the canvas, the available number of pixels is distributed over the dimensions of the frame. 

When an image that has few pixels is stretched over a larger area, the DIP (dots per inch) decreases. The lower the DPI, the worst print quality.

Memento's page editor will flag images that fall below your publisher's quality standard. Orange indlcates a potential quality issue, red signals that the image will be visibly low quality. Warning will appear on photos, clipart and backgrounds.

The only solutions for low-res warnings are to replace the image or resize it smaller, until the warning sign disappears.

Common causes of low-res warnings

Images downloaded from your school website may be down-sized from their original camera size, and not suitable to print.	Decorative clipart and backgrounds downloaded from the internet are often very low resolution.
Overzooming an image.	Resizing an element or logo past too large for its size.
Using artwork as a cover or background that was not scanned at 300 dpi.	Using a portrait image on a candid page at a much larger size than intended.
Pages designed outside of Memento saved as .jpg files, dropped as full background. Prior to designing outside of Memento, ask your publisher for their page sizes including trim (bleed) and safe margins, and be sure to render your work at 300 dpi.
