Mounting

 

Mounting is simply the process of adhering a print to another substrate. I common process would be “mounting” a poster to a “foam core” board so that the image is “rigid”.

 

There are several ways to achieve a thicker, more rigid image:

 

  • Wet mounting involves printing a paper poster and “wet mounting” it to a thicker substrate. This involves the use of a water-based adhesive which bonds the image to the rigid board. However this is a skilled and difficult process as the moisture in the adhesive can also affect the printed material in unpredictable ways such as temporarily changing the size, shape, and character of either the paper or the board being mounted.

 

  • Spray Adhesive involves the use of spray adhesives. This is suitable for smaller jobs only where the convenience outweighs the disadvantages. The problem is that the adhesive does not penetrate into the surfaces of the bonded areas as fully as it would with other mounting methods. As temperature and humidity change, the two substrates are likely to expand orcontract at different rates and the artwork may pull away and bubble. The risk of this situation happening increases as the size of the product increases and for this reason, many sprays cannot be used with artwork above a certain size.

 

  • Self-Adhesivestocks refer to any stock that has an even coating of adhesive applied and then covered with a siliconed liner to prevent it from sticking to anything else. The image is printed directly onto thisself-adhesive stock. Then the liner is pulled away as the “sticker” is adhered to the other substrate with pressure. A common situation is printing on a Self-Adhesive Vinyl (SAV) and then mounting this onto a rigid board using a pressure roller.
