Laminating Decals

When laminating does the laminate have to be matched to the vinyl? For instance could I use a high quality cast laminate on cheaper calendered vinyl? I am asking because it would be nice to use just one laminate. I purchased a roll of vinyl form my local supplier and it really doesn't like to be contour cut without curling. Even if I wait days before cutting. Yet I printed on some Oracle 751 and cut immediatly and never curled and shrinkage was small. So can I use a high quality cast vinyl for contour cut decals and use the calendered for others with the same laminate?

 

I am using a Roland SP 540V with Eco-Sol. I am not doing wraps but do need to produce high quality contour cut vehicle graphics and decals along with small signage. I read that Eco-Sol has approx. 3 yr exterior life. And depending on who you talk to some say always laminate, others say no need to, etc. After I purchased the roll of printable vinyl and failed to be able to contour cut I just used some Oracal 751 I had as an experiment. Worked great even though that is not what it is designed for. So if I use a high quality vinyl for the autos and the lower for the signage it would be nice if I could use just one laminate when needed. Are you using a calandered vinyl with contour cutting without curl? I don't really need the lifespan of cast vinyl but would rather spend the money than have edge curl.

 

Thanks for the replies. What everyone said makes sense but I can't imagine stocking 10-15 different laminates.
