Download a digital product template and use it to create your artwork. 2. Print the transfer and trim away excess paper. 3. Secure transfer to insulator using heat tape. 4. Wrap protective paper around the insulator and press for 2 minutes at 360 F. 5. Carefully remove the insulator from the press, remove the transfer, and let cool. Basic materials list for oven: • Digital template • Printed transfer • Blank stainless-steel insulator • Heat tape • Heat gloves • Scissors • SubliShrink shrink wrap film sleeve • Heat gun • Sublimation oven Basic steps using an oven with shrink wrap film sleeve: 1. Download a digital product template and use it to create your artwork. 2. Print the transfer and trim away excess paper. 3. Secure transfer to insulator using heat tape. 4. Insert insulator with attached transfer into a shrink wrap film sleeve and shrink the film sleeve with a heat gun to conform to the product's shape. 5. Place it into the oven for 6 minutes at 360 F. 6. Carefully remove the insulator from the oven, remove the transfer and SubliShrink, and let cool. GP DAVID GROSS is the president of Condé Systems, Inc. For more than 25 years he has developed and built the Mobile, Alabama, based company into the premier source for printers, substrates, and consumables serv- ing the graphic art, photography, prepress, and desktop publishing industries. you have a larger laser that requires a high- power fume extractor, be ready to have a 20-amp outlet and breaker installed by an electrician. Of course, a good manufacturer will be able to give you options if you have special requirements. All of this is a lot simpler than getting an engineering consultant to specify a blower, permanent ducting, and bore a hole through the wall, which all have to be up to code. Don't be tempted to go the DIY route or use something that wasn't specifically designed to filter out laser fumes. For ex- ample, it may seem like a good idea to hook up a shop vacuum cleaner, which may actually have a HEPA filter, to your laser. However, shop vacuum cleaners do not have critical seals and use lower grade HEPA filters. In addition, they only have tiny filters that would clog up within min- utes to hours given the extreme concentra- tion of submicronic dust particles gener- ated by the lasers. Laser fume extractors have huge prefilters and HEPAs that have efficiencies of 93% and 99.995% at 0.3 micron, respectively. And without a chemical filter having at least 20 pounds of special activated carbon, odors and toxic VOCs would pass right through the vacuum cleaner as if it were not even there. But you would definitely real- ize that it was there. Anyone who has ever used a shop vac before knows that they are also unbearably loud. Laser fume extractors have silencers, making them quiet enough for continuous use in even small rooms. KEEP IT CLEAN Cleaner air has always been important. It just may be even more so now. When it comes to health, it's all about reducing risk factors. One of these risk factors alone isn't going to necessarily cause a respiratory ill- ness. Just avoid adding unnecessary ones whenever possible. Integrating a laser fume extractor to your laser process keeps your laser cleaner and prevents pollution in your work environ- ment. Stress is also an important risk fac- tor, so perhaps there is even more value to a fume extractor if it can also give you one less thing to worry about during these crazy times.

Chau brings 19 years of extensive experience in designing air purifica- tion and fume extraction systems, having worked in both North America and Europe. He blends design, engineer- ing, product marketing, and creative thinking strategies in leading PAT's technical team to consistently output innovations that clean air.
