  1. How to Evaluate the Smoothness & Stiffness of Duplex Paper

  2. Hello! We are UECIN Suppliers Of Precision Testing Instruments in Saharanpur, India You can find us at uecin.com 2

  3. Introduction Both the stiffness and smoothness of paper are essential to determine its usability for varied purposes. And when it comes to measuring for duplex/art paper, specific instruments are used by manufacturers. That’s because of its composition and application. 3

  4. What is duplex paper? Well, duplex paper is double-layered paper often used for high-quality prints. The top layer of this paper is coated, while the bottom is uncoated. The pattern of coating promotes its smoother surface and the resulting superior quality printing. The thickness of a duplex paper typically varies between 1 and 2 mm, and the GSM varies between 180 and 500 GSM. The choice of thickness and GSM depends on the application of the duplex paper. 4

  5. Measuring the Smoothness & Stiffness of Duplex Paper To measure the smoothness and stiffness of duplex paper, manufacturers make use of UEC’s smoothness tester and stiffness tester. Let us learn about them in the following points. 5

  6. Smoothness Tester ◉ UEC’s smoothness tester is a Bendtsen-type instrument verified under the standards SCAN P 21, P 60, BS 4420, TAPPI UM 535, ISO 2494, 5636/3, APPITA/AS 1301.440, and DIN 53120. The equipment is used to measure the smoothness, roughness, and porosity of duplex paper. It also measures these properties for paper board, writing/printing paper, and tissue paper. The dimensions of the tester are 17.5 x 19.5 x 48.0 cm. The dimensions of the air compressor are 34.0 x 28.0 x 21.5 cm and of zero standard glass plate are 30.0 x 15.0 x 0.5 cm. The machine weighs 24.700 kg and can be transferred easily if required. ◉ ◉ ◉ 6

  7. Stiffness Tester ◉ UEC’s stiffness tester is a Taber-type equipment verified under standards TAPPI 489 m-69, ASTM D-747–61-T, and JIS P-8185. It is used to measure duplex paper, writing/printing paper, Kraft liner/fluting paper, plastic, paperboard, metal sheets, etc. for stiffness and resiliency. The testing unit weighs 6.350 kg while the triple shear cutter (used to prepare samples) weighs 2 kg. The dimensions of the stiffness unit are 24.0 x 28.0 x 41.5 cm while that of the triple shear cutter are 24.0 x 12.5 x 8.5 cm. ◉ ◉ ◉ 7

  8. Conclusion So, these were the important details about the testers used to measure the stiffness and smoothness of duplex paper. If you’re a duplex paper manufacturer and look forward to investing in suitable testing instruments for the same, visit UEC’s official website today. 8
