Opacity
Opacity refers to the ability of a printed image to show through from the opposite side of a sheet or from another sheet below it. Opacity increases as the weight of the sheet increases. Fillers are also added to paper during the manufacturing process to increase opacity.
Opacity is measured according to how much light a sheet blocks and is expressed as a percentage between 0 and 100. Most papers fall in the 80 to 90% range, however, an opacity of 98% will prevent a printed image from showing through on the opposite side of the sheet.
Choose paper with high opacity when printing on both sides of the paper or when heavy dry ink coverage will be applied.
Shade
Shade is the color of the paper. Paper shade may change the colors of printed images because dry ink is applied in dot patterns that allow the paper shade to show through.
The color of the paper (white, pink, buff etc.) must be specified in the Xerox Nuvera Stock Library.
When choosing paper color:
•Remember that paper shades can vary significantly among brands.
Electrical properties and image quality
Resistivity is the resistance to direct current between the two sides of a sheet of paper. The electrical properties of paper are important because a sheet must be able to attract dry ink during the xerographic process.
If a stock’s resistivity is excessively high or low, the printed image may be too light and deletions may occur.
