Tips for Putting Images on Large
Banners
Do you want to give your vinyl
banners a professional appearance that will have the maximum impact?
If you do, it is time to think about adding full color images to your
vinyl banners. One of the easiest ways to incorporate vibrant color is
to add a photograph. There are some important things to keep in mind
when adding a full color image to a vinyl banner. First, correct
resolution is vital to producing a high quality image on your banner.
Ideally the resolution should be kept to about 100 ppi when the image is
at full size. For example, an image that has a resolution of 300 ppi
when it is 8” x 10” can be blown up to approximately 24” x 30” and still
be at a resolution of 100 ppi. Since many of these images are actually
viewed from a distance, many people find that they can reduce the
resolution of the image to as low as 50 ppi and still be happy with the
results.
The next thing to think about is the importance of brightening up the
colors that are to appear on your vinyl banner. Increasing the contrast
of the image is usually an effective way to do this. When using the
software program Photoshop you can accomplish this by “pinching” the
levels. You can brighten up your light colors and darken your darker
colors by simply opening the levels window and adjusting the shadows
control towards the middle and the highlights control towards the left.
This can also help to clean up some of the mid tones in your image.
You will get enhanced brightening as well by sharpening your images.
While you don’t want to go too far, your images will look much crisper
and clear if you sharpen them up just a little bit.
The last thing to think about is working in CMYK mode instead of RGB.
The best banners are printed using solvent inks on CMYK printing
devices. It is best to use this color system when designing your banner,
rather than designing in RGB and not getting a true sense of the actual
colors that will appear on your banner. RGB has a wider color spectrum
than CMYK, so you may find that the colors are somewhat different. Some
colors that can be produced on your computer just cannot be reproduced
using solvent based inks. This is especially true when you are using
solvent based inks to print on vinyl. This is something you need to be
aware of prior to ordering your banner. If you have a particular color
that needs to be precisely reproduced it is a good idea to ask for a
proof to be produced on vinyl material so that you can check the
accuracy.
Solvent based inks are the best for full color printing jobs that will
be exposed to sunlight and a variety of weather conditions, including
rain. Solvent based inks stand up well to both wind and rain and will
not fade easily when exposed to UV rays. Sunlight will quickly fade inks
that are not solvent based. While using images and photos in your
banners can really create a great effect, it is not a good idea to use
them for outside banners unless you are using solvent based inks. Even
when you are printing banners for inside applications such as a trade
show or event you may want to consider using solvent based inks for
great performance and durability.
