Channel letters are becoming smaller, thinner, and brighter thanks to new building materials, fabrication methods, and lighting products. We take a look at some of the new products as well as the best practices for working with channel letters.


Get Bendy


Bending machines are a great efficiency in the channel letter market. Computerized Cutters, Inc., pioneered automated channel letter bending machines over twenty years ago. The company still has original Accu-Bends in the field, and all of their machines are made in the U.S.


Sign shops benefit from these machines in both time and cost savings. “If they’re buying from a wholesaler now, they can end up saving three quarters of the cost by doing it themselves,” says Carl Ondracek, president of Computerized Cutters, Inc. “If they’re building them by hand, it normally would take them forty-five minutes to an hour to bend and shape a channel letter. The machine’s going to do it in about five minutes.”


The company recently introduced its newest machine, the Accu-Bend FREEDOM, which is priced just under $20,000. “If a shop is doing one set of channel letters a month, the machine pays for itself within a year,” says Ondracek. “A lot of these guys are doing two or three, and the machine pays for itself in half a year.”

该公司最近推出新的机器——Accu-Bend FREEDOM,售价略低于2万美元。卡尔·昂德拉西克说:“如果一个商家一个月需要制作一个字母标识,那么这个机器一年之内就能回本。”“很多人一个月需要做两到三个标识,那么在半年内就能收回成本。”

The Accu-Bend FREEDOM features a space-saving design without sacrificing the capabilities of a full-sized machine. It also runs off of standard 110-volt power (as do all of Computerized Cutters’ machines) so it can be plugged in anywhere. “They can put this in a corner, and when they’re ready to build a set of letters, they bring it out, run their set of letters, and put it away,” says Ondracek.

Accu-Bend FREEDOM是一个能够在节省空间的同时不影响其功能的机器。它使用110伏的标准电源(和所有计算机数控的切割机一样),可以插在任何地方。卡尔·昂德拉西克说:“不使用的时候可以把机器放在一个角落里,准备制作字母标识时,再把它拿出来,等字母标识制作完成后,再把它收起来。” 

For the shops with space, placing the bender in a strategic spot by a router and a clinching machine can help to increase efficiency even more. “One person could be running the router and the bending machine at the same time,” says Ondracek. “Or they could be clinching the backs to the letters or putting LEDs in the letters while the machine is running. They don’t have to be there the whole time just watching the letter bend.”


To ensure efficiency on individual jobs, Ondracek says starting with a clean file helps. From there, processing the letters in a particular order is also beneficial. “If they’re going to do two sets of letters, they’re better off doing the first full set before they do the second set,” he says. “That way, they can complete the letters in a timely fashion when they have to put LEDs in it and do trim cap and all that.”


Facing Fabrication


If your shop still struggles to choose between acrylic and polycarbonate for channel letter faces, Dennis Spahr, director of Sign & Graphics for Plaskolite, says color is a good place to start. If the letters need to be a custom color, acrylic is often the better choice as it’s available in more colors.


Size is another indicator. If the faces are more than thirty-six inches tall, polycarbonate is usually used, as acrylic letters larger than three feet are difficult to manipulate, difficult to transport, and run a higher risk of breaking. For letters three feet tall or smaller, acrylic or polycarbonate can be used, but acrylic has become a popular choice due to its light diffusion and transmission properties.


Speaking of lighting, be sure to consider it before starting fabrication. “If you are using fluorescent or neon, the channel letters will need to be backed out five inches or more,” says Spahr. “If it’s LED, as most channel letter signs are now, the depth of the lighting can be as close to the face as 2.5 inches. Anything shallower than that and lines or shadowing can be an issue as well as heat concerns.


“Maintaining a suitable depth allows for better light diffusion and transmission without the pin-lighting effect behind the letters.”


Plaskolite recently released a new product designed to make lighting channel letters even easier. The OPTIX-L Black/White is a continuous cast acrylic that appears black in daylight and white when backlit illuminated. It is best used in signs that are viewed at a distance.


“In the past, sign shops would have to apply perforated vinyl,” says Spahr. “It’s expensive and time consuming. This product eliminates the need for a second layer to achieve the desired effect under daylight or nighttime conditions, reducing material costs and streamlining sign construction.”

斯帕尔说: “在过去,标识商铺必须使用乙烯基材料。”“这既昂贵又费时,而现在该产品不需要分成白天或晚上两种情况来进行制作,降低了材料成本,简化了标识的制作过程。”

Stretching the Limits of Lighting


Channel letter lighting is all about brighter and faster installs. SloanLED recently harnessed the benefits of multi-die chip technology. “LED efficacy has increased to a point where we can squeeze more chips into a product design and have the added benefit of using less area, making our designs more compact, giving us greater design flexibility, and at an increased efficacy,” says Michael Bluhm, director, Product Solutions – Sign, SloanLED.


Bluhm says the company’s Prism Lens technology has also helped sign shops to quickly illuminate channel letters with fewer rows of product, “What used to take two rows can now be done with one,” he says.


Principal LED makes installations faster and easier with its smart packaging where one bag of material equals one power supply. “We also utilize a Qwik Release Tab on all of our products so that customers save considerable labor time (and frustration) trying to remove the liner from the back of the VHB tape on modules,” says J. Bryan Vincent, partner, Principal LED.

Principal LED采用智能包装的形式,安装更加快捷、更加容易。负责人布莱恩·文森特说:“我们还在所有产品上使用Qwik Release标签,这样客户想要把模块上的VHB胶带背面的衬垫移除时,就可以节省大量的劳动时间。”

Principal LED also offers layout and estimating services. The company acquired Aries Graphics and plans to release Sign Wizard 8 by the end of July with a plethora of new features. “The online estimator [driven by Sign Wizard] automatically eliminates modules that will not work for your input sign parameters,” says Vincent.信安LED还提供布局和估算服务。该公司收购了Aries Graphics, Finally 24-volt drivers have also been hitting the market. The drivers allow for more wattage and are useful on long runs to minimize voltage drop.

Principal LED 公司还提供字母布局和估计服务服务,收购Aries Graphics公司之后,计划在7月底前发布带有许多新功能的Sign Wizard 8。文森特说:“在线估算器会自动排除不适合输入符号参数的模块。”最后,24伏的驱动器也开始进入市场。驱动程序可以使用更多的瓦特,适合长期运做,并且降低电压。

“Due to class 2 requirements, 12-volt power supplies are limited to 60 watts of power. With 24-volt, you are allowed 100 watts of power per driver to be class 2 compliant. This extra 40 watts allows the sign manufacturer to use fewer power supplies per sign,” says Bluhm. “Fewer power supplies means less labor and parts cost, which results in lower cost to the customer.”

“二类要求的标准是,12伏的电力供应被限制在60瓦的功率。对于24伏,每个驱动程序允许100瓦的电力供应。额外的40瓦可以让标识制造商使用更少的电力给标识进行供电。” 布卢姆说:“更少的电力供应也意味着更少的劳动力和零部件,这将大大的降低客户的成本。”

“The real advantage is in reduction of power supplies in larger signs,” says Vincent. “However, 24-volt is not more ‘efficient’ than 12-volt. For example, our new Tapout Pinnacle™ Stik uses an extremely efficient LED and smart system design that is 12-volt, and you can run the same number of Stiks as the most efficient 24-volt systems and at the same output. Net result: Lower cost power source, and a 12-volt system that is 35 percent more efficient than the 24-volt system.”

文森特说:“优势是使用更少的电力覆盖更大的范围”“然而,24伏并不比12伏更‘有效’。例如,我们的新设备Tapout Pinnacle™Stik采用了一种非常高效的LED和智能系统设计,即12伏,就可以运行与最高效的24伏系统相同数量的Stik,并且具有相同的输出。最终得到的结果是:使用成本更低的电源,即12伏系统,得到的效率却比24伏系统高出35%。”
