>>460337 (OP)First you (we) need to have a good idea of your use case and production needs/ goals to determine what printing and cutting methods are best...there's different types of die cutting like thermal and steel rule dies that each have pros and cons...but both are highly dependent on volume to make them worth the buy in costs for dies and a press and if you will be doing runs of less than a few thousand pieces the fab costs will be high.
A knife plotter like Cricut or a commercial grade unit and some simple software will let you cut small runs of shapes on printed sheets that would be very challenging for steel rule cutting, but won't give you the sticker and release liner cut to the same shape like a steel rule die can, you have to cut and weed each piece....might be perfect if you are making something for application to your own product you only make a few dozen of per year, but for a novelty sticker you will sell retail the costs likely won't pencil out unless you make them by the thousands.
