When i had a versacamm sp300 the best print that i ever got was a product from victory design, it was a multifix 6500 i think. I’ve never achieved a print as good on any other material, grafityp 5-7 year was pretty good.
The only reason that i stopped using it was down to price, when i first got into digital print i believed that i had to get the best quality print out there on the market so that the locals could see what a great job i do. I paid twice the price of the budget vinyls all to get a quality finish.
The problem was that the customers didn’t care, they just wanted a good job done for next to nothing.
Its still the same now, i could pay twice as much as i do but i know that the vast majority of my customers do not care. Shame.
