When dealing with ink, it is not just color you should think about. Ingredients and characteristics of the ink are important as well. Vehicles, pigments and additives are the three main ingredients of ink.
Ink Pigments- are solid elements within the ink that provide a primary color.
Ink Vehicles- provide the fluid in ink, such as oils, resins in the form of solvents, waxes and photo reactive chemicals.
Ink Additives- change inks by hastening oxidation, improving absorption and drying or altering the ink’s appearance.
The primary types of ink are opaque and transparent, but also included in the types are metallic inks and fluorescent inks. This is important in P.R. Publications because when making a brochure having a ink that will serve best in delivering your message is key.
Opaque ink is an ink that does not alloe light to pass through, often time it reflects the light. Transparent inks allows light to pass through them so that the light reflects from the paper underneath. Metallic inks appearance looks like metals, and the most common colors are metal colors, like silver, copper and gold. Fluorescent ink produces fluorescent colors, but it is an expensive process and require an extra print run. SO when you have a publication you want to print, this willl give you a little information on the characteristics and ink type and hopefully you can go from there. Just remember to have an ink that displays your message in the way you desire. InDesign, Photoshop and other publishing programs provide color samples, so have fun looking at different inks and choosing the best one.
