screen inks work very well with our ERC vinyls, it is ``not recommended"
as a money saver (the coating is needed for enamels, but not screen
inks). Our 10 oz. standard (STD) banners should be used for screen
Note to screen printers: Because our banners are sewn on sophisticated automatic equipment, the hems are straight with no bunches or puckers. This results in an easy to work with, lay flat product!
** Interestingly, traditional lettering enamels will not work (they won't dry, and we don't mean they dry slowly, they won't ever dry) on standard uncoated
vinyls, but water-based enamels will.
All of our banner blanks are made for outdoor
use. Strength and durability are generally in proportion to the
“weight” of the fabric. The lighter weight materials are less durable,
the heavier weight more durable. For two-sided banners, use the 18 oz.
“block-out” (the fabric has a barrier layer that literally “blocks
out” the light, making it totally opaque). It is also our strongest
fabric, required because by their nature two sided banners are out in the
open and take a beating in the wind.
The other factor to consider for indoor banners is whether the fabric is fire
retardant, as required by many local ordinances. While most
laminated vinyls are inherently fire retardant to some extent, they must
be manufactured to certain specifications to comply with commonly used
fire codes such as NFP 701, the California Fire Marshall’s Code and MVSS#302.
We have materials that comply with these specifications and can provide
documentation upon request.
WIND SLIT OR NOT TO WIND SLIT…
Some manufacturers recommend wind slits or “half moons” in
banners to relieve stress and wind load. Some do not. Banner installation
articles in trade magazines point out that while wind slits do allow
wind to pass through, they also weaken the banner and themselves
can rip and tear out. We recommend the use of stretch cords to distribute
the stress evenly and give the banner installation flexibility in
AN ANSWER TO…
most difficult question we are asked: "How long will a banner
last?". While weight, construction, workmanship and design
are all important and we pride ourselves on making quality products,
the wild cards of installation and the weather are important, you
can do something about your installation. So secure your banners
as best you can. HINT: bungee cords pull banners tight, distribute
the stress evenly and give banners flexibility in the wind.
We can't guarantee how long a banner will last, but we do offer a:
