Color reproduction tricks Latex inks are a new technology, and there are some important guidelines when doing color separations (such as when creating or modifying a new media preset within your RIP) that will help to optimize the printer output in terms of color gamut, ink usage and print quality. These are as follows: ● To achieve the best dark colors in vinyl gloss and other substrates, use as much black and as little composite (CMY) as possible when creating the ICC profile. ● Light inks should be avoided as much as possible in high-density colors such as secondaries and tertiaries (dark red, blue, green, ...). ● Light inks should be restricted to the lowest-density colors, starting the use of dark inks as early as possible. Typically, a color of more than 50% density should not contain any light inks. ● Light inks should be used at no more than 50% of maximum quantity. An excessive amount of light inks can create gloss artifacts in vinyl gloss substrates. Please refer to your RIP documentation for details of how to create or modify media presets. Presets for HP-branded substrates have been created following the above recommendations in order to optimize black and dark colors.
