Therefore, it's a good idea to laminate and possibly mount your prints. Copyright 1997, Board of Trustees of the University of Illinois, All Rights Reserved. You can choose between cold and hot lamination. Cold lamination is easier. Cold lamination will place an adhesive backed clear plastic over your poster using pressure rolls.
Hot lamination is a similar process except the rollers are heated.
Hot lamination will affect the appearance of an image compared to the same image not laminated. The image will appear deeper, more saturated and the hue will shift slightly towards magenta. The resulting image will be stiff and may not need backing. You can choose between glossy and matte finish. Locally, Dean's Superior Blueprint seems to be the best bet.
