When looking for a new paper to use for your high speed inkjet projects, remember to get all the paper the details. Characteristics like brightness, whiteness and shade level of the paper can impact the inkjet color outcomes for your project. Lets talk about how some of the manufactured paper specifications and how brightness can directly affect your color fidelity.

Understanding brightness. The brighter the paper, the more vivid and crisp your letters, images and colors appear. Many paper brands measure paper brightness using of two scales: US(Tappi) Scale. European(ISO) Scale. Environmentally friendly paper. Brightness ISO 2470 – Measurement of diffuse reflectance factor (ISO brightness) T 452 – Brightness of pulp, paper and paperboard (directional reflectance at.

It’s easy to have a general idea of what the term brightness means but, there can be confusion as to the technical definition and how it affects the appearance of your final product. Let’s get technical:

Brightness is the volume of light reflected off the sheet of paper. Measured from 0 to 100, it is the measurement of reflectance of the blue (short wavelengths) of the visible spectrum at 457 nm and completely ignores the longer green and red wavelengths, thus, ignoring shade.

The brightness is much like the wattage or brightness of a light bulb.

Because of this, two types of paper with the same brightness can visually appear very different, even though their “brightness” is the same.

The higher the number, the brighter the paper.

And, the brighter the paper, the brighter and lighter your images can become. Colors on less bright papers are noticeably darker. For the most part, high chroma colors printed on brighter white papers are vibrant, but darker colors can become visually washed out.

A paper of 98 to 100 bright can affect how colors are represented and may be too bright for your ink coverage. A combination of high bright paper and low TAC requirements with light weight papers can make your ink to look dull and washed out.

If you want to get really technical, some papers can have a brightness measure of over 100 when optical brighteners are used. These are really bright papers. Also note that there are three different measures of brightness.

• TAPPI Brightness is the North American standard
• ISO Brightness – the European standard
• D65 Brightness – based on viewing in “outdoor” light (note – more likely to return values higher than 100)

Inkjet Insight Paper Finder reports paper brightness using the standard specified by the mill. Talk to your mill representative to better understand your papers actual “specs” as well as print a fingerprint on the actual paper with the profile and production machine settings.

Whether you are printing vivid color documents or important proposals, or just making copies of general office documents, the right office paper elevates any project. Some factors to consider before you place your office paper order are paper weight, brightness, recycled content and the availability of specialty papers for specific tasks.

Paper Brightness

'Brightness' refers to a specific measure of how much light a sheet of paper reflects. The U.S. uses the GE/Tappi scale and is a different brightness measurement system than the International scale. The comparison scale below, along with the new brightness icon, will guide you through the different numbers.

The higher the brightness rating, the sharper the print. Color documents should be printed on office paper with a minimum 96 brightness. General office documents only require 92 brightness office paper

Office Paper Weights

Office paper ranges from 20 lbs. to 32 lbs. These numbers indicate the weight of an 500 sheets. Between 24-28 lbs. is fine for general office documents. The heavier weight work best for for color documents.
