Perhaps you need to produce brochures to launch your new products. Maybe you need to print posters to use in a trade show. Maybe you need postcards to be mailed to your customers. Whatever you need to get printed, commercial printing can perhaps help you create the print job that you want as promotional, marketing and advertising materials have become inevitable today for most businesses. Most businesses now spend a considerable amount of money for their marketing materials as it has proven to be a great way to reach the customers. Commercial printing, basically, help your business attract attention at an affordable price. You need not spend a considerable amount of money just to get your customers pay attention to what you have to offer. Generally, commercial printing includes digital printing and offset lithography. Although digital printing is now beginning to be in use more often, offset lithography still continue to be the foremost printing technique used in color printing. Commercial offset printing makes use of the four basic ink colors � CMYK. That is, dots of cyan, magenta, yellow and black. These colors are placed side by side giving certain patterns that gives us the illusion of seeing millions of colors. However, the printing of each color of ink in commercial printing is applied separately. The letterpress is probably the oldest printing process used in commercial printing. However, before you can use this technique physical plates have to be created to represent the image. Hence, they are not useful if you have images that are not found in the typical typewriter keys. Lithography, on the other hand, is probably the most common commercial printing process especially used in book printing. Lithography uses an offset process for indirect printing. This means that the image and the substrate do not come in contact. This printing technique is inexpensive and fast, thus, providing commercial printing companies the ability to store and print different images in large quantities on demand. However, when you are considering printing copies of catalogs, brochures or newsletters you may want to consider purchasing it in bulk as bulk purchasing is always inexpensive than purchasing in small quantities. Understand that buying more reduces the overall cost by hundreds if not thousands of dollars. You would be surprised with the opportunities that commercial printing can offer. Thus, when you need materials to be printed consider doing it through commercial printing.
