Recommended Banner Installation
TO GET THE MOST FROM YOUR BANNERS:
The most common complaint in the industry is: "The banner I put up was only up for ..... and it fell down".
It is very important to realize that a Banner hung outside can be subjected to numerous forces, some natural, some unnatural. The main reason a banner fails unfortunately is due to substandard installation.
It is VERY important to select the right type of banner for the conditions.
The type of construction and the TEAR STRENGTH of the banner material used are both major considerations when making your selection.
It has been our experience that banners using grommets as the primary point of attachment is the weakest form of construction, NO matter WHAT type of material is used. For this reason, we have elected to use two SUPERIOR methods of banner construction. With our conventional banner construction we use D RINGS encompassed by nylon webbing which we box-stitched into/onto the banner. (Number of D Rings and construction varies with size of banner). Tests have proven that this method of construction increases the burst strength by up to 500% over the same banner using grommets.
HANG-UPS FOR BANNERS (R) is a far superior method of construction, even to D Rings. Using this system eliminates the pressure that conventional banners experience at the points of attachment (on each corner). The Hang-ups system distributes the pressure evenly over the entire banner not just at the points of attachment. Other major advantages are: the system will accept any banner material and the hardware is reusable.

THE MOST IMPORTANT THINGS TO REMEMBER ARE:
Use strong ropes, bungees, snap hooks, cables, etc.
Attach and pull the ropes horizontally, not diagonally (see diagrams).
Keep tension in all 4 corners with whatever you use to tie your banner.
If a rope becomes slack go back and tighten it.
Excess flapping of a banner results in tears, cracking & delamination.
Our standard banners come with "D" RINGS encompassed by nylon webbing which are box-stitched into/onto the banner. Tests have proven that our method of "D" RING application increase the burst strength by up to 500% over the same banners where grommets have been used.

WHAT TO PUT ON YOUR BANNERS:
VINYL GRAPHICS: Because banners are designed to be flexible our recommendations is to use a good 2 mil high performance pressure sensitive vinyl on all banners. Good 2 mil vinyls have better adhesive properties & are more flexible than other vinyls.
ENAMELS (Solvent): Major manufacturers in the industry, produce enamels that work with our Polly, Super Polly, Vinyl & Original banners.
ENAMELS (Water): Water baeds enamels formulated for the sign industry will work on our Vinyl & Original banners (not our Polly & Super Polly)
SCREEN INKS: Inks are specifically formulated for different types of banner materials. You should always consult your supplier for the correct ink for the substrate you are screening on.
Our recommendation for:
Polly & Super Polly: Naz-Dar 3800 series and 9800 Poly Plus
Vinyl 10 & 13 oz: Naz-Dar GV Gloss Vinyl, VF Flat Vinyl, 44000 Fast Dry Gloss vinyl, 9700 All Purpose
Original: Naz-Dar S2 Series Gloss Vinyl, 3700 All Purpose, 59000 Enamel Plus Gloss

The ABC?s of Vinyl Application
Is applying vinyl as easy as it looks? Yes, in most cases. But there is always the exception to the rule. If you are trying to put a stripe down the side of the Mayor's vintage Mercedes Benz outdoors during a 60mph sustained wind - while he is standing there watching - vinyl application can get a bit touchy. Don't ask me how I know, but we will stick close to an ideal situation here and not dig up old memories.
A. Cleaning
The key to vinyl success is cleaning. The best cleaner for vinyl application is one that will not leave a residue. Some cleaners that are widely used but should be avoided are window cleaner, paint reducer and soapy water. These can all be a problem because they will leave a film on the substrate leading to adhesion problems. Special vinyl application fluids are widely available from your supplier and also ideal to use for cleaning. If you have water-based cleaning solvent, it can also be used. The key is the solvent's basic content. A water-based solvent is OK. Oil or other chemical-based solvents are NOT OK. "Water good. Oil and chemical bad." If you need to remove residues or even wax, use some clear alcohol first. Not the stuff in the liquor cabinet, the stuff in the medicine cabinet. For cleaning as well as drying, use regular paper towels. I usually lift a roll or two from my wife's kitchen. She often say's she can't believe how fast she is going through those paper towels! Clothe towels or industrial paper towels can also leave a chemical residue.
B. Applying
Now that your application surface is clean, you are ready to apply the vinyl. This is assuming you have already weeded and applied transfer tape to the vinyl. If not, DO IT NOW! The customer is going to call and check on you any minute! (Phone rings) "Um, yes, I stopped by and ordered a sign from you twenty minutes ago....I was just wondering how you were coming along on that." I always like to answer; "Well I am currently building one hundred and eighty-seven signs from orders I just received this morning. Could you tell me which one is yours?" Then the customer goes into great detail about how his sign is supposed to look. I usually drink a coffee while their explaining all this. When they start getting really excited thinking I haven't dropped everything to work on THEIR sign yet, I say "O-o-o-h-h-h-h yeah. I remember it now." Gets them going every time.
To make positioning the vinyl easier, draw centerlines on the transfer tape both horizontally and vertically. Then measure the centers of the substrate and draw lines. Using a stabilo pencil will make the lines easy to wash away later. You should now have a cross hair on your vinyl and a cross hair on your substrate. This will make positioning the vinyl straight and level a breeze. Just line up the lines!
Wet down your substrate with application fluid. If fluid is not readily available, pure water will also work. Untreated fresh water is best. If your shop is supplied with chemically treated water, you should find some that is not treated to use. If you are applying a large area, it is ok to spray the adhesive side of the vinyl as well. Both surfaces wet will make the vinyl easier to position correctly. If you are working on a table that is a little less than waist high and you are using lots of water, be careful not to lean up against the table. The table will be sort of wet along the edge, and this will leave a damp spot on the front of your trousers. Well let's just say that if someone walks up behind you and you turn around quickly, it looks rather embarrassing. Just a little helpful advice to remember.
Line up the lines (I've heard that somewhere before) and squeegee out the fluid. Start the squeegee in the center of the cross hairs and pull down or toward yourself. Work from the centerline to the right, then from the center to the left. Put the squeegee in the center of the cross hairs again, and push up or away from yourself. Again, work to the right then to the left. While you are working be careful not to do the same area twice, it may cause an air bubble. By dividing the area in half, squeegeeing the bottom half then the top half and always working out, you will get out all the fluid and trapped air, and not stretch the vinyl.
Start squegee at centerline and work towards you
Doing the bottom half first, work to your right
Then to your left
Again, start at the centerline and work the squeegee upward
Now doing the top half, work to your right
Then to your left
C. Wrapping it up
Let the vinyl set for at least 90 seconds for initial bonding to take place. Remove the application tape at a 45-degree angle starting from the top left, pulling toward the bottom right. If it removes rather hard, soak it with application fluid or water, let it soak a few minutes, and remove. Now clean the applied vinyl and substrate to remove any tape adhesive and pencil lines. Dry and you're done!
Famous Last Words
These are the basics of vinyl application intended to increase your productivity and quality of your vinyl graphics work. With time and experience, you could become as much of an expert in the vinyl field.
All surfaces must be considered dirty and must be cleaned prior to application. A good rule of thumb for cleaning various surfaces is:
