Keeping The Thermofax Alive: Bismark Pinera Visits Lucky’s Tattoo Museum
Earlier this year, we had the pleasure of welcoming Bismark Pinera of Thermofax Repair Seattle to Lucky’s Tattoo Museum in Largo, Florida. He came to visit the museum, talk tattoo history, and — fittingly — repair a Thermofax while he was here.
For a machine that became such a familiar piece of tattoo-shop equipment, the Thermofax started life with a completely different purpose.
From Office Copier to Tattoo-Shop Staple
The Thermo-Fax was developed by Dr. Carl Stinson Miller, a research chemist at Minnesota Mining & Manufacturing Company — better known today as 3M. Miller began thinking about a faster way to reproduce documents around 1940 after spending countless hours hand-copying material while doing graduate work at the University of Minnesota.
According to the Minnesota Inventors Hall of Fame, the inspiration for his process may have come from something surprisingly simple: watching a dark leaf sitting on a snowbank absorb the sun’s heat and melt an impression of itself into the snow. Miller began experimenting with the same basic principle, building an early working prototype in 1944. After years of development, 3M commercially introduced the Thermo-Fax duplicating machine in 1950.
Instead of the wet chemical copying processes common at the time, the Thermofax used infrared energy and heat-sensitive material. Dark, carbon-containing areas of an original drawing absorbed the infrared energy and transferred that heat to the material placed against it, reproducing the image.
It was fast, relatively simple, and became a major success for 3M. Eventually, however, plain-paper xerographic copiers made the Thermofax largely obsolete for office work by the 1970s.
Tattooers found another use for it.
Finding a Second Life in Tattooing
Tattoo artists began using Thermofax machines to produce spirit masters for tattoo stencils, allowing the outline of a design to be quickly and accurately transferred onto the skin before tattooing. That specialized use helped keep these machines relevant long after most offices had moved on to newer technology.
For generations of tattooers, the Thermofax became part of the everyday process — artwork in, stencil out, tattoo on.
Today there are modern thermal stencil printers that can do the same basic job, but plenty of tattooers still hold onto their original Thermofax machines. They're a functional piece of tattoo history, and keeping them running has become its own specialized craft.
That's where Bismark Pinera comes in.
Keeping the Machines Alive
Through Thermofax Repair Seattle, Bismark repairs and restores these aging machines for tattooers around the country.
There's one obvious problem: Thermofaxes are old, fairly fragile, and not particularly fun or inexpensive to ship across the country. Because of that, Bismark will often travel to different locations and have customers bring their machines directly to him for service rather than risking a cross-country shipment.
During his visit to Lucky's, we had the opportunity to watch some of that work firsthand and sit down with him for a full interview. We talked about Thermofax history, how the machines work, common maintenance and repair issues, restoration, and what it takes to keep equipment that's several decades old working in modern tattoo shops.
If you're into tattoo history, tattoo equipment, or you've got an old Thermofax in your shop that you refuse to give up on, check out the full conversation:

One important thing for owners of vintage machines to know: not every Thermofax model is identical. The Model 45EGA, for example, was manufactured with an electrical defect that requires a conversion kit for safe operation; unconverted units are considered a potential fire hazard. It's another reason having an older Thermofax looked over by someone familiar with these machines can be worthwhile.
Don't Want to Ship Your Thermofax to Seattle?
Good news: Bismark will be returning to Lucky Supply this November to repair Thermofax machines in person.
If you've been putting off a repair because you don't want to pack up a vintage machine and ship it all the way to Seattle, you'll be able to bring your Thermofax directly to Lucky Supply in Largo, Florida and have Bismark work on it while he's here.
Appointments are being booked directly through Bismark and space will be limited.
DM @thermofax_repair_seattle on Instagram to contact Bismark directly and reserve your spot.
These machines were invented more than 75 years ago for an office world that barely exists anymore. Tattooers gave them a second life — and people like Bismark are helping make sure they're still around for the next generation.
