Paper Perplexities: Understanding Options About Buying Paper

 
Boise Paper, Salem, Oregon, USA, this past week defined common paper terms and released tips to help offices and individuals as part of the company's #BePaperSmart in 2016 project.

Routine printer papers may look the same at a glance, but there’s a lot to learn when it comes to weight, brightness, and best uses. To help everyone – from individuals to large corporations – learn how to choose the perfect paper for each project, the experts at Boise Paper compiled the following list of useful tips and terminology.
 
"Paper isn’t complicated, but there are options for a reason. Each paper is designed for different uses, and picking the right paper can have a big impact on your project," said Sarah Yedlick, spokesperson for Boise Paper. "Armed with a few definitions and tips from Boise Paper, the paper buying process can be a breeze for anyone – and printing on the right paper is the first step in making your projects shine."

Office paper is categorized by a variety of properties that affect printer or copier performance and determine the quality of the finished product.
 
Weight refers to the thickness and sturdiness of each sheet. The majority of everyday printer paper has a 20 lb. weight. Heavier weights, such as 24 lb. and 28 lb., provide more durability, stiffness and opacity for printed material. Choose a heavier weight paper for reports and presentations.
 
 
 
Opacity is the property of paper that obstructs the passage of light and show-through of printing. The characteristic of paper to block the transmission of light, or the ability to provide (low opacity, like tracing paper) or prevent (high opacity) "show through" of dark printing; the human eye is good at comparing this property, but it can be measured by instrument, and is expressed as a percentage of the light that can not pass through the sheet of paper, i.e., a 98% opacity means that 98% of the light can not pass through the sheet, and is absorbed in or reflected from the incident surface. 
 
Opacity is measured on a 100 point scale. The lower the number, the more sheer and "see through" the sheet. A higher opacity is better for office printing – especially when printing doubled-sided pages. If the paper is too sheer, ink will show through from the other side.
 
Smoothness is measured by the Sheffield test, which assigns a number to the roughness of the paper. The lower the number, the smoother and softer it feels to the touch. For example, newsprint paper is on the low end of the Sheffield spectrum, while color copy paper is on the high end of the spectrum. Paper with a lower Sheffield number is better for office printing.
 
Brightness refers to the percentage of blue light that is reflected from a piece of paper. The brighter the paper, the greater the contrast between the printed image and the paper. Most office papers are between 92 and 98 on the brightness scale. Using a paper with a higher brightness makes colors more vibrant and appealing – giving graphics and images the appearance of "popping" off the page.
 
Brightness, as specified by the TAPPI is the measurement of the amount of reflectance of blue light (wavelength 457 nanometers, 44 nm wide). There is also an ISO standard for measuring brightness (ISO 2469 -paper, board, and pulps -- Measurement of diffuse radiance factor) but this is rarely used as the CIE whiteness scale is the more common measurement.

As with whiteness, it is common to see brightness measurements of over 100, which means that more light is reflected than was originally shone on the paper, this is due to Optical Brightening Agents reflecting part of the ultra-violet spectrum back in the visible spectrum. Measurement for TAPPI brightness are often in the 110 - 120 range, lower than commonly found CIE whiteness measures as the OBA's only have a small spectrum to reflect
 
Environmentally-Friendly paper typically means the paper is made from either recovered recycled paper or wood that has been certified by a third-party – like the Sustainable Forestry Initiative® (SFI) or the Forest Stewardship Council® (FSC) – guaranteeing the fibers came from sustainably-managed forests. Recycled paper typically contains at least 30% post-consumer fibers.
 
Jam-Free Guarantee – Many office paper manufacturers will guarantee the performance of select papers. Look for third-party tests, like those performed by Buyers Laboratory, Inc., on misfeeding, curling,and jamming. "Sometimes printers are at fault, and sometimes it’s the paper," noted Yedlick. "If you’re having issues, try switching to a 99.99% jam-free guaranteed paper, like Boise POLARIS® Premium Multipurpose or X-9® Multi-Use Copy. If the jamming continues, it may be time to invest in a new printer!"

There are four basic types of printer paper – color copy paper, printer-specific (laser or inkjet) paper, multipurpose paper, and copy paper. All four are designed for different printing jobs, and they vary in weight, brightness, opacity and smoothness.

Color copy paper, such as Boise POLARIS Premium Color Copy, produces brilliant, vivid color documents with professional results. This paper is brighter and heavier than a copy or multipurpose paper and is best used for full-color flyers or brochures, client proposals with color charts and graphs or external communications.
 
For documents that contain color graphics, choose a laser or inkjet paper, like Boise POLARIS Premium Inkjet or Premium Laser. These papers are designed to ensure crisp and vivid colors based on your specific printer type and are best used for charts and graphs, documents with photos, reports, certificates or announcements.
 
Multipurpose paper, such as Boise POLARIS Premium Multipurpose, is designed for high-quality printing and copying in any printer and is best used for reports, proposals and flyers when quality, look and feel are important. This paper is ideal for impressive client- and customer-facing documents. Multipurpose paper is the best buy for offices with several different types of printers, or offices that frequently print color in large quantities.
 
For everyday, black-and-white printing or copying of emails, internal memos, forms, or bulletins, choose a lighter weight, 20 lb. multi-use copy paper with a lower brightness, such as Boise X-9 Multi-Use Copy. This paper is most efficient for mass printing.
