Fooling the Optical Sensor

12-Feb-2013

Some printer manufacturers, such as Mutoh, Summa and Mimaki, have systems that utilize a separate plotter to contour cut the printed graphics. To ensure accurate cutting of the printed graphic, the plotters utilize an Optical Positioning System called OPOS. The electric eye or photo sensor of OPOS scans the black register marks printed along the outside edge of the print, so the cutter can plot the knife cut. Read more

Are Premask and Prespacing Tape the Same Thing?

04-Feb-2013

The plethora of terms used for the application tapes sold in the sign and screen print markets could confuse anyone. In the sign market, many people just use the terms “application tape” or “application paper”. Frequently this tape is also incorrectly referred to as “transfer tape”.
If you are a purist and want to pick a few nits, the terms application tape and transfer tape refer to completely different products. Transfer tape refers to a transfer adhesive, which is an adhesive coated onto a release liner.

Storing Application Tape

Application tape manufacturers package their products in plastic sleeves, then box them in corrugated containers to protect the tape from light, dirt and humidity. If you’re not going to use the tape immediately, keep it in its box. Tape not stored in boxes is exposed to light, which can cause yellowing. Even shop lighting can yellow application tape.

To avoid problems with vinyl or any other pressure-sensitive material, carefully read the vinyl manufacturer’s technical data sheet. Product bulletins will usually contain all of the information you need, including application temperature range. The application temperature range for most vinyl films is usually between 50⁰ and 90⁰F (10⁰ to 32⁰ C). For some films, the minimum application temperature range is higher.

The Effect of Clear Coating Matte Silver VinylEfx Film

11-Dec-2012

Spraying RTape Matte Silver VinylEfx® film with a clear coat will change its appearance from a matte finish to a satiny finish. The reason for the change is that this VinylEfx® pattern is textured on the first or outside surface of the film. Other VinylEfx® patterns are embossed on the second surface. When you spray the clear coat on the matte silver, it fills in valleys of the texture. The film will not become as glossy as a Smooth Silver or chrome pattern. But it will look different. Read more

Challenges in Developing a Premask for Air Egress Liners

06-Dec-2012

Vinyl films with air egress release liners have almost eliminated bubbles and wrinkles from applied graphics. Here’s how the product works. These release liners are comprised of multiple layers of paper, a polyethylene coating and a siliconization layer. The polyethylene coating of the release liner is embossed with a textured pattern. The textured structure of the release liner imparts tiny air channels in the adhesive of the vinyl film. Think of these as escape routes for air. As the installer squeegees the facestock, the air between the film and the substrate is directed through the air channels to the edge of the graphic.

Thermal Transfer Printing on VinylEfx® Films

30-Nov-2012

One unique characteristic of our VinylEfx® product is the deep embossing, which creates the 3D illusion in patterns, such as MultiLens® and Diamond Plate™. Deeply embossed patterns, however, can cause problems, when printing with thermal transfer systems, such as the Gerber Edge®. Printing on films, which are not perfectly smooth, can result in flaking, in which there are voids in the printed image. "East Coast Artie" Schilling, spokesperson for Gerber Scientific, offers the following suggestions to surmount these printing challenges.

Application Tape Tips

17-Oct-2012

Whether you laminate application tape by hand or with a laminator, avoid trapping air bubbles between the vinyl graphics and the application tape. Bubbles and wrinkles in the application paper often result in bubbles and wrinkles in the applied graphic, regardless of the skill and effort of the installer. If you inspect the adhesive side of a graphic, after removing the release liner, you often can see the formation of wrinkles and bubbles in the adhesive. In the application process, you will just transfer these wrinkles and bubbles to the substrate.
