Printing Photos on Large Display Banners
Adding full color graphics to vinyl banners will give your banner designs with greater impact and a more high quality appearance. Adding a full color photo to your vinyl banner is most often the easiest and best way to do this. When you intend to add a photo or image to a large banner design, you should keep a number of things in mind. For the image to look clear and crisp it really should have the correct resolution. For most large display projects such as vinyl banners, display backdrops, window graphic, and popup displays, try to keep resolution at about 100 ppi (pixels per inch) at full size. In other words if you have an original image that is 8" x 10" with a resplution of 300 ppi - a standard resolution used for offset printing - then you can appropriately increase its size roughly 24" x 30". That will give you a final resolution of 100 ppi. In fact you can probably go as low as 50 ppi and still get good quality output, because these images are normally meant to be viewed from a distance of 10 feet or more away. Second, it is often necessary to brighten up the colors of your vinyl banner images. You can usually do this by increasing the contrast. In Photoshop the most effective way to do this is by "pinching" the levels. Open the levels control window and pull the shadows (dark shades) control towards the middle (to the right). Then pull the control for the highlights to the left. This will brighten your light colors and darken your dark colors while eliminating some of the "mudiness" of the mid tones. You can also brighten your photos by "sharpening" them. Punch up your images with a bit of sharpening and they will almost always appear crisper with greater impact. But don't sharpen them too much. Finally, it is best to work in CMYK mode rather than RGB. Vinyl graphics and other large format graphics are just about always printed on CMYK printing devices using solvent inks. Rather than counting on the printing device to make the conversion (RGB is the default color system used on the computer) convert the images yourself so you can see what you are going to get. RGB can be misleading since it can display more colors than can be printed by CMYK. There are colors you can see on a computer monitor that cannot be reproduced with CMYK inks especially not with solvent based inks on a material like vinyl. You are best to know this before you get the printing done. If it is necessary to create a specific color and if time permits a proof can be printed on the actual vinyl banner material to give you a clear picture of how it will look. Another important point to realized is that the choice of ink will impact the durability of the job. Outdoor projects should be printed with true solvent inks because they are ideal for full color printing that will be used in bright sunlight or other potentially harmful weather conditions such as rain or snow. Solvent inks resist fading due to UV exposure, and stand up to wind and rain much better. Non solvent inks will fade much more quickly in bright sunlight. Even for indoor projects it is often better to use solvent-based inks because they produce a much more durable finished product. This is especially important for situations that require graphics which will be rolled and unrolled many times, and be subjected to a lot of handling.
