print: stock

how its made:
paper is made from cotton, pressed pulp wood or recycled paper.

weight:
the weight of stock is a description of the density of fibers that make up the paper. the weight of the stock is measured in grams per square meter. something to take into consideration is that usually, the heavier the paper the longer the stock will last as it's more durable.

thickness:
this is measured in caliper (inches) or millimeters. the thickness does not effect the quality of the stock 

colour:
to do this the fiber pulp is dyed before pressing. these are more expensive then white paper. there are bright, parchment, and pastel shades, along with metallics.


texture:
this depends on the manufacturing process as well as the size & quality of the wood fibers. if the paper is tightly pressed with fine fibers the paper has a smoother finish. less pressed stock with larger fibers results in card/board.
Laid: machine-made paper with a pattern of parallel lines. 
Vellum: a paper finished to appear like the writing material vellum, which may be either prepared animal skin or parchment, i.e., a slightly rough finish. 
Linen: a paper finished to appear like linen, a woven cloth that can be used as canvas. 
Felt: paper that is textured by being pressed with patterned wool or felt during the manufacturing process. 
Embossed: a paper with a raised design created by pressing or hammering the design onto its back.

opacity
this refers to the density and thickness and it's measure on how much image and text can be seen on the reverse. tracing paper is created by immersing quality paper into acid.

finishes
varnish coating
the varnish can be applied with the inks or as a separate run and keeps the inks intact
matt, satin & gloss
the quality of the paper determines the intensity of the ink and there's quite a difference when comparing matte & gloss. printed onto matte paper, ink sinks into the paper creating a more dull looking finish where as the ink sits on the surface of the gloss stock therefore making the ink appear more intense and deeper in appearance. satin allows for slightly less intense colours then gloss but it doesn't have the shine.
