Color Graphics, Digital Graphics
The power of full-color images is unmistakable. They grab your customers’ attention, instantly bringing their focus to your product or service. A major advance in visual technology, full-color graphics make a strong statement about your company's leadership in the marketplace.
Among the many marketing messages we encounter each day, only a few have lasting impact.
With full-color graphics (also referred to as large-format prints or digital graphics) from FASTSIGNS®, your messages cut through the clutter.
One of the greatest challenges of full-color digital printing is ensuring that the colors printed are the colors you expect. Your FASTSIGNS® staff will take the necessary steps to ensure that your colors are produced as faithfully as possible within the limits of our technologies. Here’s how different devices (scanners, monitors and printers) display color.
The RGB color model uses a dot pattern of red, green and blue light to reproduce a full color image. It is used by scanners and monitors.
The CMYK color model uses a dot pattern of cyan, magenta, yellow and black inks or toners to reproduce a full-color image. It is used by virtually all digital printers.
There are many spot color models, but the process is simply that of printing a specific solid color.
Full color adds a new dimension to your graphics and involves some new considerations. Below are a few key terms you'll want to know, plus some examples of how variations in resolution affect the appearance of a graphic.
The reproduction of any color image by applying certain ink colors in varying proportions. Originals can be either RGB or CMYK files.
The addition of one or more colors to a graphic by applying inks of those specific colors. Spot color cannot reproduce full-color images.
An abbreviation for "dots per inch", DPI is a measure of the density of ink dots used to reproduce the image. The more dots in the image, the higher the image clarity and the better the ability to enlarge that image.
More important than the DPI is the total number of pixels in a file. Pixels determine the final file size for processing and image quality. For large-format printing, a good rule of thumb is to plan for 100 to 150 pixels per inch (ppi) at the final printed size. PPI is commonly referred to as DPI. For example, if you wish to have an image printed 24" x 36", your computer file should have a minimum of 2,400 pixels (24" x 100 ppi) by 3,600 pixels (36" x 100 ppi), for a total of 8,640,000 pixels. At an average of 3 bytes of storage per pixel, that's about a 24MB file. Anything less simply won't have the quality you expect.
The distance from which your graphic will be viewed determines the DPI required:
The equipment used to produce full-color digital graphics is different from that used in standard service-bureau output, so your files should be formatted specifically for large-format, full-color techniques.
