Can the 7800 able to print on vinyl, and then use the cutter to contour cut around the decals?
If so...what inks should I look into?
What Vinyl decal material should I look into?
What laminate should I look into?
I answered all in post 4.
If you are looking for a 24" cutter with ARM capabilities "GOOGLE". Many merchants here sell what you say you are looking for.
Sublimation ink on vinyl? NO.
You CAN print on vinyl with your Epson. But know the limitation the material has. Pigment ink will last the longest depending where you live and the UV in your area.
You need to do your homework and contact vendors. I am finished.
