Black text

Ghosting is the phenomenon that occurs in almost every printing technique, when it comes to colored print. This is caused by the fact that in most cases, specific color is obtained by superstition of two or more colors in the printing press. Each color is applied to separate print cylinder. Due to unavoidable backlash in the machine (and many other factors, among which are the experience and skill of the printer) cylinder doesn’t always hit precisely the same spot. Thus, ghosting appears – edges are accompanied by shadows or quite clear stripes of the same color sticking out like a sore thumb. Thus, the graphic elements have to be trapped which slightly increases contour and the ghosting becomes invisible. It is worth noting that the trap is usually in the same color resulting from the combination of colors composing the object and the background around it.

However, it’s an entirely different case (at least it should be), when it comes to black text. Many people believe that the only way to achieve beautiful black text is through the process of combining it from all four CMYK colors. It’s often proposed when there’s a colored background. Because – hey, if the background is colored, and the text itself is composed from several colors, it has to be extremely easy to design proper traps to avoid ghosting, right? Well, this is not true and for a very good reason. Trapped text loses its clarity: edges are thickened and the whole thing falls apart. If, on the other hand, we would not use any traps at all, our text most certainly, would not be black, but colorful with four-colored contours sticking out in different directions.

It’s worth to remember, that if the project contains black text, it should be composed of only one color – black K=100%. Moreover, if it’s placed against the colorful background, it should be printed on a top of it, at the very end. If the text is cut out from the background, there is a high possibility of white spots popping out at the edges.

Many people struggle selecting the composing colors of black text in their project – that’s because they usually work on RGB palette which has no black, so to speak. In that case, it is advised to convert the whole project into CMYK Palette, and then make sure that the composing color of black text is just K=100%
