Business cards are usually printed on a four-color press. A card is referred to as a ‘four over zero’ when it is a full color in the front, without a back. It is called a ‘four over one’ when it is a full color in the front, with a black and white back, and a ‘four over four’ when it is a full color in the front and the back.
But before you thinking about the printing, you need to determine which aspect of the card is most important to you. Most likely, you will be concerned about the quality of the cards, limited as you might be by a particular model of a printer. So if your card has an image on it, printers say it is best to use glossy paper. On an inkjet printer, this will ensure the print looks as good as the real image. The paper cost is double when compared to ordinary paper, but the quality is superior.
You must, however, remember that inkjets have a strange way of zooming the print output, though only slightly. While this may not affect the clarity of the print, it might cause each of the next rows of cards to be slightly offset. While this does not happen in the case of laser printers, the best way to tackle it is to use the Scale field while setting printer calibration. Also, do not forget to set the desired print quality and color options in the Print dialog.
Textured paper is a good idea if you want to give the card a unique look. It is not something companies use often. One thing to remember, however, is that glossy and textured cards are not compatible with laser printers.
