Inkjet Printer Paper Sizes and Types
GLOSSARY
Brighteners = optical brightening agents (OBAs) make paper whiter and increase it's brightness - brighteners remove the off-white or yellowish appearance of the raw materials in the paper
Brightness = the higher the number the brighter the paper is, the amount of light reflected off the paper
C2S = Coated 2 Sides, this paper can be printed on both sides - also called Duo or "double sided"
Canvas = usually a blend of cotton and polyester, acid free and pH neutral
Dmax = is the measure of the maximum density black (deepest black) that a paper and ink combination can produce
Fine Art Paper = is generally (not always) 100% cotton rag, acid free and pH neutral
gsm = grams per square meter, this is the weight of the paper
Hand Made = paper made with a wire mesh mould - hand made paper has randomly placed fibers as opposed to machine made papers where the fibers are generally lined up in the same direction - the randomly placed fibers add strength to the paper - generally has a deckled edge in which the paper is thinner as you get nearer to the edge
mil = the thickness of the paper - one mil equals 1/1000 of an inch - example: 12 mil paper equals 0.012 inches
micron = the thickness of the paper - 300 microns is about 0.01181 inches or 11.81 mils
Mouldmade (mould made) = paper made by machines that simulates the hand mould paper process - the mould is really a wire mesh wrapped on a drum
Opacity = the higher the opacity, the less the printing shows through the paper, especially important for C2S (duo) paper
pH value = indicates whether the paper is acidic or alkaline - acidic paper deteriorates over time - buffering the paper lowers the pH by adding alkaline and can increase the life of the paper - calcium carbonate is a common buffer - a pH value should be 7.0 to 10.0
Thickness = usually measured in mils ( 1/1000 of an inch) or mm (millimeters, 0.001 inch = .0254mm ) - please note that a thicker paper does not necessarily mean it is more rigid or heavier than a paper with with less thickness
Weight = inkjet paper is usually measured in gsm, which is how much one square meter of the paper weighs in grams
