Baryta

Baryta or barium sulfate (BaSO4) has been traditionally used as a brightener or whitening agent in silver halide photography papers. More recently the term has developed a new meaning thanks in part to marketing efforts of inkjet paper manufacturers. The term is now synonymous with the style of papers which traditionally used Baryta and in general. The newer inkjet papers may or may not utilize Baryta as a whitening agent and care should be used to verify its use. The whiteners longevity in digital papers has not been widely tested as of yet.

Grain (Paper)

The direction in which fibers within a sheet of paper run. 

Depending on the fiber material used in the paper the grain may be different. Fibrous materials like cotton have long fibers which orient themselves in a parralel direction.

Papers may be referred to as both long grain or short grain depending on the cut. If paper grain or fiber of the paper is aligned along the length of the paper or long side, the paper's grain is referred to as grain long. The direction of the grain is important when scoring and/or folding the paper. Scores and folds should always be made in the direction of the paper grain. Some manufacturers denote the grain direction in their lot numbers like Moab so they can provide paper appropriate for special projects.

Rag Paper

Paper made of cotton is commonly referred to as rag paper. Traditionally cotton rag papers were made entirely of cotton textiles however today the most common source is cotton linters. Cotton linters are the waste from production of things like cotton t-shirts. Not all rag papers are made entirely of cotton and often the manufacturer will provide a cotton content amount like 75% rag. Rag papers are generally more stable than their pulp counterparts. Cotton is naturally acid- and lignin-free.

Should I print my photos on resin-coated or fiber paper?

This is a personal preference and will be determined by not only your preferred look-and-feel of the final print but also the material and longevity you are trying to achieve. Also an important consideration is the final display of the print itself.
