Educating with Big Pieces of Printed LexJet Tyvek

Montessori Timelines Printed on LexJet Tyvek

The title is a tad misleading. It’s not the LexJet TOUGHcoat 3R DuPont Tyvek that educates, but what ETC Press Inc. prints on the Tyvek that does it.

Educational Timelines Printed on LexJet TyvekETC Press, a subsidiary of ETC Montessori based in Houston, provides curriculum and educational materials to Montessori and applied learning schools. Among the important teaching aids ETC Press produces are 107″ x 17″ educational timelines printed with the company’s HP Designjet Z6100 on LexJet TOUGHcoat 3R DuPont Tyvek.

ETC Press executive director Aki Margaritis says LexJet Tyvek is the go-to material for the timelines because it’s durable and images with clarity.

“The timelines need to be very durable because they’re handled quite a bit by the kids. A timeline needs to last in a class for a minimum of five years with constant handling, and the LexJet Tyvek has held up,” says Margaritis. “The images are coming out nice and crisp, the colors are vibrant, the kids love it and we’re very happy with the print material.”

Margaritis adds that a student once unwittingly stamped the edge of one of the timelines with the tip of his chair leg when he sat down, leaving an indented ring in it. “We told the teacher to just let the timeline sit out like it normally would, rather than trying to push out the crease or roll it up, and sure enough, the indentation went away,” he says.

The timelines tie into the curriculum the company publishes. The timelines often tie into each other, as well. For example, one timeline outlines the history of communication from 25,000 B.C. to today, while another follows the same timeline, but focuses on the progress of mathematics.

“The kids can line up the timelines one next to other and see the relationship between communication and mathematics and how each affects the other,” explains Margaritis. “They have to be small enough to fit in the classroom and large enough to allow two to three groups of kids to gather around the timeline and focus on the different events and subjects they’re studying.”

Finishing Banners Quickly, Reliably & Economically

Why sew when you can tape? Whether it’s to make pole pockets, create a seam for grommets, or to tile two pieces together for a larger banner, double-sided LexJet Heavy Duty Banner Tape provides all the advantages of sewing, plus it’s faster and is easier on the material.

Sewing perforates the banner material, which can lead to fraying and cause premature failure at stress points. Heavy Duty Banner Tape avoids this problem, and is designed to be conformable to the varying checkerboard-like patterns in the scrim.

Banner Tape application makes finishing banners a lot quicker and easier than sewing, plus it's less expensive and less damaging to the banner material.

Because it’s so conformable, it works with any material one might use for a banner, from polypropylene to fabrics. Simply mark a straight line on the back of the banner where the edge of material will fold over, apply the tape along the mark and attach the edge of the banner to the tape.

A 3×8 banner should be easily finished in five to ten minutes, which is much preferable to waiting for 24 hours or more if you send it out to be sewn. Even if you have this capability in-house, there is far more time and labor required to sew a banner.

Banner tape is less than 30 cents per linear foot, so the cost of finishing with it is minimal. “My six-year-old son can use banner tape, but he can’t use a sewing machine,” says LexJet’s product manager, Jeff Leto.

“The only time I would think someone would want a sewn banner is if that’s the look they want, so there’s no other reason why you wouldn’t use banner tape as a direct replacement for sewing,” says Leto. “The only thing to keep in mind about banner tape is if you make a pole pocket and stick ropes through the pocket instead of a pole. At the ends of the banner where it’s folded over on the corners, they will need to be re-enforced. You can either reinforce the corners with a grommet, or a single stitch with carpet thread. This will prevent the corners from lifting.”

If you’re installing the banner with ropes, or something similar, Leto says it’s preferable to run the rope through pole pockets as opposed to looping rope through grommets on the four corners of the banner and it tying them off. Instead, run the rope through the pockets. This makes the tension across the banner even, as opposed to all of the tension being placed on the grommets at the four corners.

Another method is to attach bungee cords to the four corners since the bungee cords will give in the wind and distribute the tension evenly along the banner. Furthermore, this method is much more preferable to cutting wind holes, which looks bad and effectively lowers the lifespan of the material.

“The nice thing about banner tape is that it fits all of the potential environments in which you would install a banner. There’s a reason why you’d use Tyvek, polypropylene, a 500×500 denier vinyl, or a 1000×1000 denier vinyl in different application situations, but there’s one product you can use to hem all of them in any environment,” says Leto.
