Is it possible to laminate A1 size composition yourself i.e. short special machinery, and how much does it cost?
Yeah, easy....it does take profoundly of sellotape and a steady hand, mind you.
Lamination is done professionally. If you can't get it done for some reason, later cover the document in clear plastic wrapper and seal it to hold on to it safe.
A1 is huge, and its unlikley you can do it for lb9.99!
I think you would need to rob it to a professional!
I bought an A1 size laminater from Argos for lb9.99. Operation is simple.
IF you want true lamination, then you stipulation a laminating machine. If you dont want to buy one, go to someplace approaching Kinko's and they can do it for you. Or buy clear contact paper and do it youself, but it won't really be laminated, just covered contained by clear plastic.
