Air emissions

Substance waste in the air from combustion and production activities, especially involving carbon dioxide (CO2).

Alkaline paper

Paper having a pH value greater than 7, which contains calcium carbonate. Also called acid-free paper. Rolland fine papers are all alkaline.

Basis weight

Unit of measurement used to determine the thickness of paper, which is calculated based on the weight of 1,000 sheets in standard format in its category.

Biogas

Gas resulting from the decomposition of waste in a landfill that is sent to the Rolland mill and used in place of fossil fuels to produce paper. Using this green energy substantially reduces greenhouse gas emissions. 93% of the thermal energy needs of the Rolland mill are filled with biogas energy.

Brightness

Property of the whiteness of paper, measuring the ability of the sheet to reflect a ray of light, taking into account the color blue in the spectrum.

Coated paper

Paper surfaced with a coating to provide a smooth, bright printing surface.

De-inked fibers

Fibers from old papers and cardboard that have had ink and any other contaminant removed in order to reuse them. The recycled fiber used to manufacture Rolland papers are deinked.

Digital printing

Printing produced by sending digital information to a printing plate, a cylinder and then a substrate.

ECF - Elemental Chlorine Free

The virgin fiber included in the paper have been bleached without chlorine, but with a chlorine derivative. The recycled fiber part used in Rolland fine papers contain no chlorine or derivative. Rolland’s virgin fiber are ECF. In addition, the recycled fiber used by Rolland are made using no chlorine nor derivatives.

Ecological footprint

Calculates the quantity of natural resources consumed by an individual, group or company, as well as the waste and pollution generated by their lifestyles.

EcoLogo

The EcoLogo Program is a Type I eco-label, as defined by the International Organization for Standardization (ISO). This means that the Program compares products/services with others in the same category, develops rigorous and scientifically relevant criteria that reflect the entire lifecycle of the product, and awards the EcoLogo to those that are verified by an independant third party as complying with the criteria.

Fine paper

High-quality printing papers, including coated and uncoated papers. Rolland makes fine papers since 1882.

Finish

Textual qualities of the paper surface.

• Antique: Rough, natural-looking finish used on uncoated papers, especially for books.

• Smooth: Smooth, soft finish used on uncoated papers.

• Matte: A non-reflecting finish used on coated papers.

• Gloss: High-gloss finish with bright reflection used on coated papers.

• Linen: Honeycomb finish reminiscent of canvas, used on uncoated papers.

• Vellum: A relatively rough paper with a natural appearance that resembles an eggshell, used on uncoated papers.

FSC recycled

Certification from the Forest Stewardship Council (FSC), which certifies the 100% post-consumer content of the paper, taking into account all transformation steps, from raw material to the consumer.

Grammage

The mass of a surface unit of paper determined by the standard test method and expressed in grams per square metre (g/m2).

Lignin

Non-cellulosic part of wood that keeps the fibrous parts together. The lignin is extracted from chemical pulp to prevent the yellowing of the sheet. Rolland papers contain no lignin.

Mechanical pulp

Paper pulp from wood obtained entirely by mechanical means. Rolland does not use mechanical pulp to make paper.

Offset printing

Indirect printing method created by the ink being transferred between the printing plate, the rubber blanket and the substrate. Continuous presses and sheet-fed presses fall under this printing category.

Opacity

The capacity of a paper to hide the characters printed on its other side.

Pages per inch

Unit of measurement primarily used for book printing, which specifies the number of pages contained in one inch. Note: A sheet contains two pages.

Permanent

An alkaline or neutral paper, also called acid-free, that can resist more than 100 years in normal warehousing conditions. Criteria and certifications are established by the American National Standards Institute (ANSI). All Rolland papers are permanent.

Post-consumer

Contains wood fiber that has been recuperated entirely from paper used by consumers through recycling programs and has been de-inked without chlorine.

Post-industrial

Contains wood fiber that has been recuperated from paper used in industrial applications and has been de-inked without chlorine.

Processed Chlorine Free (PCF)

Manufacturing process of recycled paper that uses no chlorine or derivatives. All recycled fiber used by Rolland are Processed Chlorine Free. The company is certified by the Chlorine Free Product Association.

Recycled

Contains wood fiber that has been recovered from paper used in industrial applications and consumer waste.

Reprographic

Reproduction process using laser printing or ink jet.

Security paper

Paper containing features to deter counterfeiting and forging, used, for example, for money and passports.

Smoothness

Paper containing features to deter counterfeiting and forging, used, for example, for money and passports.

Solid waste

Residual solid products resulting from the process of manufacturing pulp and paper.

Suspended particulate in water (SPW)

Refers to all insoluble solid matter found in water.

Tint

Color shade of paper.

Top side

Side of paper facing upward during production.

Uncoated paper

Paper without coating and mechanical pulp providing a uniform, non-reflective surface. Rolland only manufactures uncoated fine papers.

Virgin

Paper made exclusively from wood fiber harvested from forests.

Watermark

Permanent mark within the sheet of paper made while the paper is still wet. Watermarks are a sign of prestige and security.

Whiteness

Property of the whiteness of paper, measuring the ability of the sheet to reflect a ray of light, taking into account all the colors in the spectrum.

Wire side

Downside of paper that comes into contact with the canvas of the paper machine during production.
