So I need to go to any flex printing or lamination shops and get a laminated A3 size sticker paper right printed by placing all the logos in any word document.
yup.I didn't ask for A3 paper ,but I had to make 200 stickers with the same colour of visiting card which had my new cellphone number printed on it ,to stick above old number,so it needed A3 sized one.They called me and edited in computer to see if it was right size and colour.It was a big photography studio with printing,key lamination ,seal making,number plate/house name board printing etc.I think ,if you go to a more advanced shop you could make exact replicas.But before , confirm they do it.
