Offset belongs to the most widespread and the cheapest printing technology (in case of bigger amounts) – indirect printing from the surface. Printing colour is transferred upon the material from the surface of a printing form indirectly through an offset coat. (Source: Wikipedia)
This technology is suitable in case that the artwork contains subtle grid changes, photographs, or plenty of colours, and therefore the use of screen-printing would become too costly. On the other hand, classic offset using conventional colours on PVC can reach only a thin colour film layer, which also means worse colour durability and resistance against weather conditions. For the above reasons we use UV offset instead of a classic one. Among other great advantages of this method stands the fact that the colour layer does not evaporate, the colour is not absorbed by the material and after coming out of a UV tunnel, it is 100% hardened without any loss in the height of the colour film. A sticker made in this way looks better than normal sticker, and it is also more resistant against weather conditions. We use the best colours available on the market to ensure the colour stability of our stickers in the exterior. Still it is vital that the customer is aware of the fact that printed advertising cannot compete with cut-out advertising, and offset sticker is less durable than screen-printed one. Therefore we cover offset sheets with a thick layer of polish with UV filter, to ensure good-looking, long-term advertising.
