airports where the contrast of white lines on a light grey concrete surface is not explicit enough. By spraying black paint adjacent to the white lines you can create a distinct contrast. You could draw dual colour lines by use a marking machine with just one gun. If you do not want to lose time while waiting for the paint to dry, a machine with two guns is a better option. Each gun will be used to spray a different colour. Diagonal lines Non-driving zones are often crossed out with parallel diagonal lines. They can be regarded as straight solid lines applied in a certain pattern. These types of markings are regularly done manually. Usually a lot of time is spent on calculating and applying physical guiding lines. By using a road marking machine with spray tips that can be adjusted to spray under a certain angle, you can make this job a lot easier. Some advanced machines feature an auto-layout functionality that easily cuts layout time for making horizontal lines in half.

traffic flow. Dependant on their type (see below), they indicate whether crossing from one or both sides is allowed or not. Sometimes a solid double line is used as stopping line. Double lines exist in different types: • Two solid lines • One solid line combined with one skip line • One solid lines transitioning to a skip line combined with one skip line transitioning to a solid line • A zipper line (used on airports) Drawing double lines with just one gun is possible by covering the same area twice, but it is inefficient. A smarter and faster way is to use a machine with two guns. And if you really want to do the job fast, accurate and comfortable you better choose a machine with two automatic guns. That way you can draw any type of double line you want with a single push of the button. Dual colour lines In some countries preliminary traffic lanes (in case of road works) are marked with yellow lines. In situations where the preliminary traffic lines transition to white permanent markings two colours are needed. Dual colour lines are also used on

programmable settings for the line segment length and the interspace between two line segments. A semi-automatic mode is convenient for restriping: the line segment is drawn automatically but you determine the starting point of each line segment. Double lines Double lines are often used in road marking applications. They are placed in the centre of the road, separating
