Today, custom lanyards are a popular giveaway item at trade shows, concerts, conferences, and sporting events. Of all the items that can be stamped with a company’s logo, a lanyard is one of the most useful. Where promotional items are concerned, there are a few terms customers should know so they can effectively communicate with their graphic designer and get great results.
Raster and Vector Images
These are the two image types most people are acquainted with. A raster image is also known as a bitmap image, and it is composed of thousands of pixels. When the pixels are enlarged beyond capacity, they can look blurry. While raster images are appropriate for the manipulation of colors, they’re not suitable for resizing.
A vector image differs in that it is composed of points rather than pixels. Each point has defined coordinates that are connected to form a shape. Such shapes can be filled with colors and can be resized with no decline in image quality. Where lanyard printing is concerned, vector images can provide the best quality.
RGB vs. CMYK
Crisp, clean, bright colors will make a company’s branded lanyards stand out. To get those eye-catching colors, customers should know the differences between CMYK and RGB.
CMYK is cyan, magenta, yellow, and key (or black). These colors are used by most printers. However, digital printers use spot coloration and CMYK color fields to offer a wider selection of hues when printing on lanyards.
RGB combines red, green, and blue to produce different shades. Although most printers can work in an RGB configuration, files should be set up in CMYK.
PPI and DPI
Resolution is a measure of the quality or clarity of an image, and DPI and PPI are the most important terms. DPI, or dots per inch, refers to the quantity of dots on each printed page. The denser the DPI, the higher-quality the resulting image is. Files should be at least 300 DPI for lanyard printing. PPI, or pixels per inch, is a reference to image quality as seen on a screen. PPI can be used to design images, but customers should ensure that the file is converted to DPI before it’s sent off to print.
These are some of the most important terms to consider when printing lanyards. Consult a printing company or graphic designer for further advice.
