The media profiles define the relationship between the colors the scanning system sees 
and the colors the printer is able to print. For some printers there is a set of pre-installed 
media profiles (High-gloss Photo, Coated, Bright White, etc.). However, if you need to 
print on other media, or desire a color reproduction system that better matches your 
media, it is advisable to create new media profiles, as specified...

Image enhancement is used to improve the original image or a portion of it. The final 
image will not be an exact copy of the original but, rather, a re-interpretation of it that 
corrects some of the original’s shortcomings (e.g. stains, fuzziness).

media. At HP, we analyzed various environments and reached the following 
conclusions: 
 
• Glossy paper (such as HP Universal High-gloss Photo Paper) has a much wider

3.3 Guidelines to create or validate a media profile 
 
Many of the color problems appearing in the HP Large Format Color Copiers products 
are related to the mismatch between the media’s color characteristics set up in the touch
