One colour / two-colour printing

The offset printing technology can be applied not only in full colour scale, but also printing the pantones (including gold and silver). Often one side of the printing sheet is printed in full colour system (CMYK), but the other side in one colour (for instance, invitations with coloured cover and one colour text inside). Also the corporative identity materials of the company (business cards, envelopes, document forms) are mostly printed using one or two colour printing.
