Substrate (printing)
From Wikipedia, the free encyclopedia
For other uses, see Substrate.
Substrate is a term used in converting process such as printing or coating as a more general term to describe the base material onto which e.g. images will be printed. Base materials include (though are not limited to):
- plastic films or foils,
- release liner
- textiles,
- fabrics,
- plastic containers
- any variety of paper (lightweight, heavyweight, coated, uncoated, paperboard, cardboard, etc.), or
- parchment.
The end use of the printed / coated product is the main factor used in determining the substrate. For example:
- A daily newspaper has a very limited life span of one day and is sold at a nominal cost. Because durability and longevity are not needed, a paper that has a low cost and low quality is chosen to be the substrate - newsprint.
- In contrast, a monthly magazine requires bold and sharp graphics and images (for the pictures and illustrations in articles, and for the advertisements). It also requires durability and longevity (because the magazine will read multiple times, over a period of time). Therefore, a high quality more expensive gloss paper is chosen.
- A release liner requires a variety of different properties, depending on its targeted end use.
