Commercial Printing Help

Going from the do-it-yourself ink jet printing process to the commercial printing process can be quite an intimidating experience and quite a challenge if you’re not prepared. You’re probably comfortable with the equipment you’ve been using, and can even get pretty good results from it. But now it’s time to turn your work over to the professionals.

The printing industry has a language of its own, with its own lingo. This short guide will help you with the basics and hopefully make the transition a little easier:

RGB vs CMYK

RGB stands for the colors red, green, and blue. This is a reference to the primary colors of light. Computer monitors, TV screens and projectors display images in RGB color mode.

CMYK stands for the colors cyan, magenta, yellow, and black (K). This is a reference to the primary colors of pigment or ink. Most of the time, when something is printed professionally, it is probably printed in CMYK color mode.

An important fact to remember is that these two formats are NOT compatible with each other. In order to go from your computer monitor to paper, or vice versa, the original color mode must be converted to the other.

Image Resolution

This is a term you’re probably familiar with. Image resolution is how many dots per inch make up an image, whether on your monitor or on paper. Both computer displays and printers display or create images by reproducing colors one tiny dot at a time. These are pixels on your monitor, or dots on a printed piece. Computers display images at around 72 dots per inch (dpi), while professionally created prints are produced at much higher quality, at 300 dpi or greater.

Why is this important to remember? Because you could not take a small image off the internet, enlarge it on your computer, and attempt to print it. You’d end up with a very fuzzy and distorted image that lacked any sense of clarity. For the best results, you’d want to prepare your file at an original color depth of 300 dpi. You probably don’t need to go any higher than 300 dpi, and if you can avoid it, you shouldn’t go any lower than 150 dpi.

Bleed

A bleed is the area around the edges of your page that will probably be cut off. Why might you want to include a bleed? If you want your pictures or graphics to go all the way to the edge of the paper, you’re going to need a bleed. There’s probably no company out there that can cut each paper exactly right every time. So you’ll want to include about a 1/8” to 1/4″ bleed around the edges. Ensure that no important or relevant text or graphics is included in this area. Before “going to press,” you’ll probably want to ask your printing company how much bleed would be acceptable

There’s a lot more to learn in the world of commercial printing, but these printing basics should give you a pretty good start.

Take a moment to think of all the printed materials you encounter every day. The list could be extensive: billboards, brochures, direct mailers, business cards, flyers, etc. These printed materials come in all different sizes, thicknesses, colors, and all types of creative designs. But how did all of these things come about? How did they go from an idea, to a design, to the final product? You’ll find out below.

The fairly new concept of commercial printing is the process of going from artwork to a piece of paper or card stock. Most companies today use a form of offset printing that transfers to paper four separate colors to make the final color image. These colors are cyan, magenta, yellow, and black; also known in the industry as CMYK.

So what is the definition of commercial printing? The overall process of printing is actually quite simply and it hasn’t changed much over the last 100 years. It begins with aluminum plates that are created (pressed out) from the artwork. Most of the time there is one plate for each of the four CMYK colors. Each plate is then wrapped around large cylinders that allow the ink to fill up the cut or pressed out shape of the aluminum plate. Ink is then poured into the cutout and then transferred to a rubber roller. This roller is called the blanket cylinder, which is used to let the paper roll within to retrieve the right level of ink. And finally, the impression cylinder is a roller that pushes the paper along the process at around 10,000 sheets per hours to absorb the necessary amount of ink. There are four presses – one for each of the four colors. As the paper moves along each press, it retrieves one color at a time and eventually ends up in a heated area, where the paper can dry before printing on the back side.

To sum up the process, commercial printing involves determining the proper levels of water and ink for each color. The aluminum plate determines how much ink the paper can absorb, and the rollers press the image onto the paper, one at a time.

Commercial printing has many advantages over standard desktop printing. It can create professional and outstanding results that many people can use and enjoy. Many, if not most, companies utilize this form of professional printing. The key, however, is to ask your printer the right questions and understand how their process works. Chances are, CMYK offset commercial printing will be the best method for you to print amazing marketing materials.
