As it is already clear from the name of the event (Reklama Polygraf Obaly) and as verified by the long-term tradition – colourfulness and printing quality demonstrated by using the state-of-the art technologies are directly reflected in all the halls of the trade fair, whether on posters, packages, displays or advertising objects. Printing is carried out by using both CMYK process and spot colours. And just, as far as spot colours are concerned, an important role is played by sample collections. Of course, the offer of the exhibitors usually includes both material and printing sample collections so that everyone can find their favourites there.
