The glossy side of the paper is the printing surface. Follow the printer manufacturer's instructions for loading the media correctly.
Avoid handling the unprinted media on the printing surface. Smudges, marks etc can affect the image and colour quality.
Avoid exposing the media to extremes of temperature and humidity; high humidity can reduce the image quality.
Store the media in the original packaging to prevent accidental damage to the printing surface.
Printed media can be handled soon after printing but care should be taken to avoid touching the printed surface. Prints should be fully dried before stacking or storing.
