7 Advantages of Double A Paper


Everything is in the fiber, and Double A high fiber content makes it the best copy paper for high-speed machines. Here are seven reasons why:


Good Runnability: Our precision rotary paper cutting machines significantly reduce paper jams in copiers, a quality proven in a tough. No Jam Runnability test performed under independent laboratory conditions in which 60 pages per minute were copied for 24 continuous hours. 


Printing Sharpness: Doubles smooth surface allows for good toner transfer, making copies as sharp as the original. 


Excellent Smoothness: Double A smooth surface gives it a high quality touch and makes for effortless copying, especially in high-speed machines. 


Bright Appearance: Double A 148-151 CIE whiteness provides high print contrast and resistance to fading. 


Enhanced Copier Performance: The sharp blades on our advanced sheet cutting machines result in a lower dust content when printing or copying, prolonging the life of office equipment. 


Two-Sided Use: The high opacity and excellent formation resulting from Double A high quality fiber allows double-sided use. 


Longer Storage Period for Documents: Acid free paper has longer shelf life, making it perfect for storing documents. 


Double A Paper Properties 


Double A has 30 million fibers per gram, a unique characteristic that gives Double A its: -


Smooth surface -High density -High opacity- Low ash content -Good formation


Smoothness: Smoothness is a measure of the flatness of a paper surface and affects how it moves through a printer or copy machine. A smoother surface also has a high-quality feel, is pleasing to the eye, and is particularly well suited to high-speed machines. 


Roughness is taken into account when measuring a paper moothness, and the lower the number the better the paper. Paper roughness varies from the top of a sheet to the bottom due to gravitational forces. 


Bending: Bending strength improves a paper contact with the copy machine and prevents tearing the higher the bending strength the better. 


Density: Another property of good paper is density, which refers to its strength, smoothness and opacity the higher the density, the smoother the surface, but with lower opacity and strength. 


Opacity: Opacity is the measure of how much light is prevented from passing through a sheet. High opacity is usually associated with high filler content and results in a high ash reading under test conditions. Double opacity comes from the unique features of its pulp, giving it high opacity with low ash content. 


Ash Content: Ash Content is another key to good paper formation a property that is associated with filler use, high ash content equals high filler content. 


Formation: Formation is an indicator of how evenly fibers and fillers are distributed in a paper sheet. Paper with poor formation has an uneven surface with thin spots and thick spots.


Light Fastness: Light fastness is a good indicator of a paper resistance to fading or change of color when exposed to sunlight the longer the line, the longer a paper will retain color.
