A business card can also be coated with a UV glossy coat (offset-uv printing). The coat is applied just like another ink using an additional unit on a sheetfed press. That being said, UV coats can also be applied as a spot coating - meaning areas can be coated, and other areas can be left uncoated. This creates additional design potential. UV Coating is not to be confused with coated stock, which has a gloss or semi gloss finish that is applied before printing.
Business cards can also be printed with a digital copier, which uses toner fused onto the surface of the card, however many modern printing firms instead utilise high end "Digital Presses," now distinct from office copiers, which range from light production units such as the Bizhub 5500 from Konica Minolta, to state of the art units such as the latest HP Indigo Digital Presses.
While some of the older office copiers may have had problems running heavy business card stock, the newest digital presses can print on stock as heavy as 407 g/m2 (150# cover stock),[1] and special substrates such as polypropylene. Available in both sheet-fed and web-fed models, many modern digital presses can emulate Pantone spot colors, print in up to seven colours in one pass, and some even contain embedded spectrophotometers and air-assisted feeding systems.
UV coats, and other coatings such as aqueous coatings are used to speed manufacturing of the cards. Cards that are not dry will "offset", i.e., the ink from the front of one card will mark up back of the next one. UV coatings are generally highly glossy but are more likely to fingerprint, while aqueous coatings are not noticeable but increase the life of the card. It is possible to use a dull aqueous coating on uncoated stock and get some very durable uncoated cards, and using UV coating or plastic lamination can also be applied to thicken thin stocked cards and make them more durable as well.
When cards are designed, they are given bleeds if color extends to the edge of the finished cut size. (A bleed is the extension of printed lines or colors beyond the line where the paper it is printed on will be cut.) This is to help ensure that the paper will cut without white edges due to very small differences in where the blade cuts the cards, and it is almost impossible to cut the cards properly without. Just being a hair off can result in white lines, and the blade itself will pull the paper while cutting. The image on the paper can also shift from page to page which is called a bounce, which is generally off by a hairline on an offset press, but can be quite large on lower end equipment such as a copier or a duplicator press. Bleeds are typically an extra 3.175 (1⁄8) to 6.35 mm (1⁄4 in) to all sides of the card.
