Series "V" only uses fulltone elements. This series provides the shortest sequences and is therefore to be used for package printing.
This series uses fulltone elements, 40% and 80% screen elements as well as a slur element. The structure is as follows: First the fulltone elements for each color, then the screen and slur element for the first color. Then again all fulltone elements and the screen and slur elements for the second color and so on. This series is optimized for commercial printing.
This series is nearly the same as the "VT", only the slur element is replaced by a grey-balance element.
This series contains fulltone elements as well as 40% screen elements. The order is a fulltone and a screen element for the first color, then a fulltone and a screen element for the second color and so on. This series is for package and commercial printing.
