Scaling Ideally, each raster image should be saved at the actual size, and it will be placed in the document at the optimal resolution for the printer. If the image resolution is correct for the printer, there is no quality advantage to be gained by scaling an image to a percentage of its actual size. If you scale a large image to a percentage of its actual size, you incur unnecessary file transfer time, because the image data for the entire large image is sent to the printer. If an image is placed multiple times at markedly different sizes in a document, save a separate version of the image at the correct size for each placement. If you must place an image at greater than 100% in a document, remember that the output image resolution is affected. For example, if you scale a 200 ppi image to 200%, the image is printed at 100 ppi.

Scaling
Ideally, each raster image should be saved at the actual size, and it will be placed in the
document at the optimal resolution for the printer. If the image resolution is correct for the
printer, there is no quality advantage to be gained by scaling an image to a percentage of its
actual size. If you scale a large image to a percentage of its actual size, you incur unnecessary
file transfer time, because the image data for the entire large image is sent to the printer. If an
image is placed multiple times at markedly different sizes in a document, save a separate
version of the image at the correct size for each placement.
If you must place an image at greater than 100% in a document, remember that the output
image resolution is affected. For example, if you scale a 200 ppi image to 200%, the image is
printed at 100 ppi.
