Resolution warnings

Book products allow you to set resolution warnings/errors at setup time. These warnings apply to images used on yearbook pages.

Your client will see warnings on their pages if they use an image that is below your recommended values.

They will also apply to backgrounds.

How resolution warnings are triggered

There are several common triggers for low-resolution warnings.

• your client has downloaded images and logos from their school website, not realizing they have been downscaled.
• your client has downloaded photos, clipart and backgrounds from the internet, not verifying their quality (nor the legality of doing so!)
• your client has over-zoomed an image.
• your client has stretched a small image to a larger size.
• your client is using a scanned artwork that is not 300 dpi and set it to a full background.
• the school photography service has provided portrait images below the recommended PSPA 640x800 size.
• your client has used a portrait image on a candid page at a much larger size than intended.

How to avoid low resolution warnings in your clients' books

First, ensure that you set your book settings to a reasonable level. 
Yearbooks are generally not printed at the quality of fine art photo books, so there is no need to challenge your clients with very high resolution demands. The goal is to block very low quality images that will print pixelated.

We do not recommend using values over 200 dpi to warn or 150 dpi to error. Anything higher than these values does not allow your clients sufficient flexibility to use image resources available to them.

Never set your warning to 300 dpi - background canvas images are highly likely to display warnings. Clipart expanded even slightly beyond its first-dropped size is also likely to trigger warnings.

Second, educate your client on where they should gather images. 
They should primarily use original photos directly gathered from the photographer, not downloaded from a website.
They should use the backgrounds and elements provided in the software, or from reliable copyright free sources downloaded at as large a size as possible.
They should never use images found in a general "google search" or copied from an online publication such as a newspaper or a magazine.
