I can guarantee our rolls roller operator can mount 10x faster (Not even joker) On our table, than you could on a laminator, and be more accurate.
Nothing beats a flatbed applicator for mounting signs - Now if youre doing 4-5 signs a day, it doesnt matter. If you're doing hundreds a day... then a flatbed applicator is a must.
Both have their uses - A roll to roll is good for anything over 10 Ft of laminating. If you're a slow/small shop and your prints are generally 10 Ft long.... a flatbed applicator is quicker than a roll to roll, especially if you're using multiple different overlams.
Anything 10FT > I use a roll to roll.
Anything under I use our flatbed. But we have cheap gloss, cheap matte, Intermediate gloss/matte... premium gloss/matte, along with 4-5 other specialties..Most of our products are full rolls which we put on our roll to roll laminator... Everything else thats a specialty is just flatbed - I wouldnt want to load our roll to roll up 6 times a day with different overlams for 6 FT of material each time we print something.
Both have their uses, which is better for your shop is up to you.
