Ricoh makes a toner machine (with white ink too!) that can print 13"x27.5", so getting close, there are certainly ones who can... however I do take exception to the thought that "the perfect way to do something was figured out 20 years ago.", I believe this is the same mentality that drove the design of the Space Shuttle based on the standard sized Roman Chariot (btw, this was NOT the most efficient proportions for the boosters, but "the perfect solution" to standardizing train tracks was apparently found over 2000 years ago! The Romans standardized the chariot width, basically all western roads were made to this standard, end then so was the American railroad - so any booster that had to travel by rail had to have a maximum diameter, unfortunately much smaller than ideal.)
But when there’s a problem that doesn’t need fixed and anyone who knows how to use google can find the supplier who can print them the industry standard way cheaper than you can make them yourself, what’s the point - oh, and like I mentioned prior, you get a supplier when you buy the machine new, so you’re already in the door. They’re dirt cheap. Mud dirt. And if we’re talking the toner route, that hard substrate material isn’t cheap - and nobody natively makes it in large sheets, or in roll form - I’ve looked when I considered that route. Some of those machines can be overridden to run longer sheets, but if I can’t get the transfer media at all or without a massive commitment, what’s that do for me? The media being white and non heat confirming is also an issue. If the paper rips under the concave and pressure issue, which will happen since it’s not designed to conform around curves, you just lost a $17 blank and your media cost.
As for those semi successful tests I had with the industrial Toner transfers, though they could work if the carrier was thick enough to handle the curvature of the board and transfer process, they chipped real easy. These had a heat activated adhesive screened to them as well that was designed for wooden surfaces. But, because of the nature of the white and color portion of the graphic being toner and not a paint-like ink, they couldn’t handle even a brush of the fingernail. They looked nice, vibrant, but when it comes down to it, if they can’t handle a little ding from a finger, they don’t pass the test.
DTF - clothing DTF will adhere, but the chemistry of the adhesive powder and the inks being high stretch makes them feel gooey on the surface. You know what that means, it’s not skateable.
UV DTF could work, for center/small graphics at most, full coverage wouldn’t be fun with the curves and active adhesive and you’d be paying 5-10x the traditional transfer cost because you have to print color, white, and clear from your UV and use a lamination system to add adhesive to the prints. Doing a wet apply would be dangerous to the board, so we’ll rule that out.
Solvent / eco solvent / latex transfer doesn’t work because all the transfer techs are clothing only where you print to the surface of a vinyl or pet like material, where that printed material is then transferred to the substrate after a potential contour cut. Definitely not skateable, and if we’re going the vinyl/pet application route, we might as well do traditional vinyl since the final product would be the same visually, but the traditional vinyl would have a better hard surface adhesive on it - since clothing adhesive is a different compound all together. UV isn’t natively heat stable, which is why there is no heat transfer vinyl products on the market marketed for UV.
Printing and mounting adhesive vinyl/pet/etc from Solvent/Eco-Solvent/Latex/UV. This works for decoration, and it works well. If it’s going on a wall, and you used good material, nobody would know the difference unless they knew what to look for. There are a couple places online that sell them this way, but they all specify that they’re for decoration only, as like I’ve mentioned before, you can’t successful skate vinyl because of it not being permanently bonded, 1/1 with the surface.
They’ve added things along the way. Using holographic materials, foils, dimensional graphics underneath the main graphic and so on. China and the R&D spending skateboard industry at large keeps these things developing. Nothing stays a true trade secret, your vendor will eventually crack the code and be able to produce you the next big thing every 5 years when one comes around.
As for the companies domestically that produce their own heat transfers, they all produce a product that reacts fairly the same - it feels and wears like ink, and is transferred with a heat confirming PET release film that move the ink off the plastic and permanently bond it to the boards clear coated surface. It’s all designed to mimic what the customer expects, because at the end of the day, the customer is who matters.
Printing skateboard heat transfers in a wholesale fashion doesn’t exist in America not because it can’t be done, but because it can’t be profitable. When my process is complete, it won’t be offered to others. Not because I want to protect the process, but because I’ll be double what you’ll be charged from the China supplier. The only reason you develop in house transfer printing so so you can compete in the printer boards rush order and one-off market. Production runs would still be cheaper to outsource if the customer doesn’t pay the rush fee or order under the minimum. Self sufficiency only matters if it’s more profitable when you’re in an industry that has many places you can take your dollar.
Hopefully this clarified things a little better.
