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.

Mouldmade

Mouldmade paper closely resembles handmade paper and is made on a cylinder-mould machine.

In The Book of Fine Paper, the bible of paper making, the process is described in great detail. "The cylinder [wrapped in wire or screen] revolves half immersed in a vat of highly diluted pulp. As it turns, it forms a continuous fibrous sheet (called a web). This layer is picked up at the top of the cylinder by a suction roller surrounded by wet felts. The web of paper then passes through the 'pressing' section consiting of upper and lower rolls which mechanically squeeze out the water. Both rolls are covered by wet woolen felts, giving a surface to the paper which is very similar on both sides. As the web is fed through the drying section, it passes around a series of steam-heated cylinders before being finally reeled up at the end of the process as a continous roll of paper." (Turner, 18)

Mouldmade papers are typically more expensive than so-called machinemade papers as they are slower to produce and require great attention to detail.

pH Value

pH value indicates whether the paper is acidic or alkaline. Acidic paper will deteriorate over time, buffering the paper lowers the pH by adding alkaline and can increase the life of the paper by helping to absorb any acid in materials that may come in to contact with the paper. Calcium carbonate is the most common buffering agent.

RC Paper

Resin Coated (RC) papers are a type of photographic paper made from a pulp base that has been coated with a plastic. This plasticized base is then coated with an ink-receptive coating or silver halide coating for photographic printing.

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.

Silver Halide Photo Papers

In photographic paper application silver halide crystal was used in gelatin form to coat the surface of several wet process photographic papers, traditionally used in black and white photographic prints. Several inkjet papers such as Fiber (fibre), baryta, and silver papers attempt to replicate the look-and-fell of traditional silver halide papers in an inkjet receptive form.

The paper I want to print on is not listed in my printer driver, can I still use it? Do I need an ICC profile?

The short answer is yes. Each printer manufacturer creates basic paper settings and names them according to their branded products. Using a similar setting will in general provide a good starting point. Most printer drivers also include advanced tools to adjust the ink and color to effectively create your own settings. ICC profiles do this work for you so we recommend finding or creating a customer profile for the best results.

Vellum

Vellum is cotton plasticized translucent paper typically used for technical, architectural and CAD drawings. Because vellum is more durable than typical pulp-based paper it is typically used for blueprints in technical fields but makes a great creative element to use as an overprint or print separator.

What settings and/or profiles can I use on inkjet metallic paper?

For printing on metallic inkjet paper we recommend using the highest quality print settings and ICC profiles for Premium Glossy Photo Paper (Epson Printers), Glossy Photo Paper 240gsm (Canon Printers) and HP Universal Instant Dry Gloss Photo Paper (HP Printers). We’ve tested all settings on our lines of both Mitsubishi Grace Pearlescent Metallic Inkjet Photo Paper & Chrome Pearlescent Metallic Inkjet Paper, and have got great results using all three profiles. If these profiles aren’t listed on your printer simply use a glossy or luster setting for best results.

What type of media can I use on my inkjet printer?

Generally, you can use any type of paper that has an inkjet receptive coating. You will need to make sure that the thickness (measured in mils) of the inkjet media will not harm your printer. You can check what thickness media your printer will take by checking the printer specifications. We recommend referring to your printer's manual for the recommended materials. It is also appropriate to verify whether or not your printer uses dye- or pigment-based inks and match the substrate.

What's the difference between hot- and cold-press papers?

In general, hot-press papers are smooth whereas cold-press papers are slightly textured.

"Handmade paper with a smooth finish is described as hot pressed or H.P.. The term is not strictly accurate, for papermakers achieve this particular finish in a variety of ways: the sheets may indeed by pressed between heated glazing rollers, but they may also be passed through cold, highly polished metal rollers with pressure; historically the surface was obtained by polishing with a smooth hard object such as an agate or other stone." (Turner, The Book of Fine Paper, 34.)

Cold-press papers are often referred to as NOT (all caps) for not hot-pressed. "It describes a surface which is the result of parting and re-pressing handmade sheets wihtout any intermediary felts or boards. The finish is slightly textured..." (Turner, 33.)

Digital paper manufacturers and the digital photography industry have further loosened the terms to mean either textured or smooth.
