We are trying to use the Cricut Smart Iron Vinyl for our bumper numbers, but for whatever reason they aren’t sticking. Our settings (with a Cricut EasyPress 2) are 315 degrees F for 30 seconds, with the shiny side of the vinyl up. We are trying to stick it on the AndyMark Bumper fabric (the lighter color side).
I don’t have much experience with the Cricut Smart Iron on Vinyl, but I have been using the AndyMark fabric this year for bumpers. I have had success with an iron on the cotton setting (which is about 400F) and 45ish seconds of pressure to get our bumper numbers to stick, good luck!
We have the same process, 305 degrees. But we do the first press, then put a teflon sheet over it and do a second press for another 30 seconds. It does need some pressure, if it’s a hand press be sure to push down on it. Seems to work well!
Put some pressure on it and then try letting it cool completely to room temperature before removing the film. Sometimes certain materials will be listed as “hot peel” and they just aren’t for whatever reason. I have that with several HTV materials this year. Whatever bond you get will be strongest when it cools off. Highly recommend using a teflon sheet as an insurance press.
We have a Cricut Hat press and it takes usually double the time that Cricut recommends to bond.
There’s a great thread about bumper numbers HERE you should read through.
In my post HERE, I talk about using specific vinyl for Codura. I’m not sure what you’re using for fabric or vinyl but it matters. For me it was ~350 degrees, using a heat press WITH a non-stick cover sheet. I assume a regular (dry) iron would work but it didn’t for me. Obviously making sure you “reverse cut” your numbers in vinyl and the vinyl side is down in contact with the fabric, so the shiny plastic is what you iron on is important. And use some sort of cover sheet to so you’re not putting the iron ON the plastic substrate. Hope that helps!
If I’m having trouble getting vinyl to stick, I’ll press them turn it over and press it from the bottom. Same amount of time as I did for the top. The trick with the easy press is to use all your weight behind it. Press on a table that is a waist level or below so you can really press down on it.
We have a couple different fabrics that we’ve used through the years that we tested on, but across the board we got the best result using the “Sport Flex” Cricut vinyl as opposed to the traditional iron on vinyl. It is specifically made for polyster but we’ve had success using it on the nylon bumper fabric.
Try pre-heating the fabric first, then quickly positioning the number, then pressing. Also, Siser Easyweed works pretty well for material for the numbers.
