This is the most common and basic option. Graphical elements are cut to certain shapes from different fabric colors. Then they are sewn on to individual panels. Overlaid artwork is mainly used for lettering, logos, and elements with distinctive outlines and colors. Its advantage is the simplicity and subsequent take out of the graphics (e.g. after contract completion). Disadvantage would be a slightly heavier envelope.
Graphic is sewn into the fabric. This is then cut to parts, which are later sewn together completing one panel made of different colors. Using this method gives us lighter weight. On the other hand, the work on the balloon gets a lot longer, which increases the final price. Since it is more difficult to take this kind of grpahic out of the envelope, it is used for large lettering (exceeding 3 m), logos, etc.
For placing a photograph (either a real photo or a complex logo with shades and color transitions) is used a Kubicek printing technology. It allows us to print an arbitrary motiv based on bitmap graphics. This unique technology colors the fabric fiber itself and the printing becomes inseparable part of the envelope fabric. It is distinguished by long-lasting color stability and mechanical solidity.
An advantage of this method is an absolute freedom of graphical imagination. At the same time a high definition original pattern is needed as well as higher budget. Usually the printed panels are sewn in, but could be patched on as well - depending on particular case.
