      <abstract>
        <p>This article discusses images printed with a high speed continuous ink-jet printer on uncoated paper using dye-based inks. For such images print quality and waterfastness depend highly on paper additives. Optimizing paper properties requires tradeoffs. For example, increased print waterfastness
 leads to a large loss of print optical density. With improved waterfastness also comes more print raggedness. Color-to-color bleed and black print quality generally are opposed to each other. Why the trade-offs occur and ways of overcoming them are discussed.Total cationic charge dictates
 waterfastness but limits ink coverage, which contributes to lower optical density. Increased sizing lowers waterfastness because of an inability of the ink to interact with cationic charges in the paper. Increased sizing improves black print quality but sometimes leads to lower optical density
 because of even less ink coverage. Concurrently, higher sizing often lowers color-to-color print quality by increasing bleed. Using and changing additives that alter the absorption and adsorption of inks adjusts the balances of properties. For example, just reducing surface starch levels significantly
 increases optical density for a given level of waterfastness.</p>
