Many people have the misconceptions with the brightness and whiteness of copy papers. These are two totally different things theoretically. Printing is totally dependent on the color of the paper. The printing quality increases with the increase of the whiteness of the copy paper. Absolute white copy paper is 100% dazzling and it is impossible to achieve as it needs to reflect 100% of the light shone with zero absorption.
Brightness is related to the fluorescing and bleaching agent added to the paper in order to achieve the dazzling white paper. If you hold such a paper under a black light, they will be brighter as compare to cotton rag papers. The image displayed on the paper is improved with the improvement in the whiteness and brightness of the paper. Colors on the less bright papers are usually dark. White paper always appears white, but when placed side by side, various white papers show a range of color from a softer, warmer white to a very bright, cool white. The more blue light reflecting off the surface, the brighter and whiter the paper appears.
Different companies have different brightness scales. The brightness is affected by the following factors:
- Rate of absorption
- Type of ink
The choices of brightness and whiteness ratings are really a personal preference that will be related to the nature of the printing project, expected results, perceived results, and cost. You need to buy the best suitable white paper for your company for the better work experience and reputation the company. You also need to select the well reputed supplier for purchasing a good quality copy paper with effective whiteness or brightness depending on your choice and nature of your printing machines.
