Putting Images on Large Vinyl Banners
Originally published in
Trade Show Buzz
Adding full color images to vinyl banners will create banner designs with
more impact and a more professional appearance.
Putting a full color photograph on your vinyl banner is often the easiest
way to do this. When you want to add a photo or image to a vinyl banner design,
try to keep a few things in mind.
First, in order to look crisp and clear an image must
have
the correct resolution. At Banners-Canada we try to keep resolution at
about 100 ppi (pixels per inch) at full size. In other words if you have an
image that is 300 ppi at 8" x 10", then you can comfortably blow it up to about
24" x 30" (which will give you 100 ppi). In fact you can probably go as low as
50 ppi and still be quite satisfied with the output, because these images are
normally meant to be viewed from a distance of at least 10 feet 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 easiest way
to do this is by "pinching" the levels. Open the levels window and pull the
shadows (dark shades) control towards the middle (to the right), and pull the
highlights control to the left. This will brighten your light colors and darken
your dark colors while getting rid of some of the "mudiness" of the mid tones.
"Sharpening" your images will also have a brightening effect. Your images will
normally appear much crisper and sharper when you "punch them up" with a bit of
sharpening. But don't go overboard.
Finally, we recommend working in CMYK mode rather than RGB. Vinyl banners at
Tradeshow-Display-Experts.com are printed on CMYK printing devices
using solvent inks. Rather than counting on the printing system to convert your
RGB (the default color system used on the computer) convert it yourself so you
can see what you are going to get. RGB can be misleading since it has a broader
color "gamut" than CMYK. There are colors you can see on a computer monitor that
you simply cannot reproduce with CMYK inks -- especially not with solvent inks on
a medium like vinyl. You might as well know this before you get the printing
done. If it is important to reproduce a specific color -- and if you have time
--
a proof can be produced on the actual vinyl
banner material to show you how it will look.
At Tradeshow-Display-Experts.com we use
true solvent inks because they are ideal for full color printing intended for
use in bright sunlight or other harsh weather conditions (such as rain). Solvent
inks resist fading due to UV exposure, and stand up to wind and rain. Non
solvent inks will fade in bright sunlight. Using images (photos, logos, special
artwork, etc.) on your banners is a great idea, but we don't recommend using
this approach for outside projects unless they are being printed with solvent
inks. Solvent inks also produce much more durable
vinyl banners for applications like trade show banners or event backdrops
where they will be rolled or folded many times, and handled a lot.
