|help: overview > device guidelines|
These are suggestions for color mode, printable area, and ppi requirements for our output devices. Before you begin to size your scans, determine the smallest acceptable scan resolution requirement for the device.
Exceeding the suggested PPI could result in a file
too large to output or additional megabyte charges. Save time and expense
by testing the procedures that you will follow from start to finish.
Considerations for scans, file size, and resolution
Vector-based graphics are suitable for type and logos,
even when they are scaled to larger sizes. However, when you increase
the size, any included raster images must have a proper resolution for
the final dimensional print size. Because the number of pixels in an image
is fixed, increasing the size of a raster image decreases its resolution,
and decreasing its size increases its resolution.
