Terminology and definitions of special paper for wood-based panel finishes



1. Special paper for wood-based panels decor ration

Special paper for wood-based panels decor ration, including base paper, printed paper, impregnated decorative paper, wear impregnated decorative paper, overlay paper, impregnated overlay paper, wear overlay paper, wear impregnated overlay paper, balance paper, and impregnated balance paper.


2. Base paper

Titanium white paper is impregnated with amino resin that has certain absorption and covering properties. It is divided into two categories: solid color paper and printing base paper.


3. Printed paper

The original paper by printing, with color, pattern, pattern paper.


4. Impregnated decorative paper

Plain paper or printed decorative paper impregnated with amino resin and dried to a certain degree, with a certain resin content and volatile content of the film paper, by heating and pressure can be glued to each other or with the artificial board substrate.



5. Wear impregnated decorative paper

Contains certain wear-resistant materials, and has a certain wear resistance impregnated decorative paper.


6. Overlay paper  


Covering the outermost layer of the substrate surface, the decorative layer plays a protective role, with a certain degree of absorption and good transparency of the paper.


7. Wear overlay paper  

Contains a certain amount of wear-resistant materials on the surface layer of paper.


8. Impregnated overlay paper

Surface paper impregnated with amino resin and dried to a certain degree, with a certain resin content and volatile content of the adhesive film paper, by heating and pressure can be glued with decorative adhesive film paper.


9. Wear impregnated overlay paper

The surface film paper contains a certain amount of wear-resistant material.


10. Balance paper balance paper

The paper plays the role of strengthening and balancing the slab and has certain absorption and covering properties.


11. Impregnated balance paper

Balance paper impregnated with amino resin and dried to a certain degree, with a certain resin content and volatile content of the film paper, by heating and pressure can be glued or glued with the substrate.


12. Crease     

For various reasons lead to the decorative paper folding phenomenon, and impregnation pressure paste crease in the surface of the final product can not be eliminated, the decorative effect will have a negative impact.


13. Color variation

The same batch or different batches of decorative paper and standard samples, respectively, with the same resin, the same substrate, and the same hot pressing process at the same time after impregnation pressure paste, are placed in three standard light sources (D65, D50, TL84) for comparison, the color differences.


14. Stock lump

Paper manufacturing process because the raw materials are not fully dispersed, and the formation of hard texture, density of the block.


15. Surface picking

Paper surface fibers or titanium dioxide of the phenomenon, easy to cause incomplete printing patterns or dipping glue after the decline in paper coverage.


16. Dust point

Any unwanted embedded in the paper, different from the paper color, opaque small pieces of material.


17. Split edge

The decorative paper edge tear phenomenon, resulting in a paper in the printing and gluing process is easy to break the paper.


18. Reformed reel core


Due to insufficient strength of the core or by the impact of external forces resulting in the core twisted or out of the round phenomenon.


19. Reel end planarity 

The difference between the two ends of the paper roll from the reference end surface.


20. Soft roll

Because of the paper roll on both sides of the paper force inconsistent or paper thickness on both sides of the paper roll caused by the inconsistency of the two sides of the paper roll loose tight phenomenon.


21. Missing dots

For various reasons missing print or pattern dot missing, the pattern dot off, resulting in the decorative paper surface revealing the original paper color dots.


22. Stain

In the decorative paper, surface appears non-design pattern texture of the dirty spots and spots.


23. Width variation

After printing, the difference between the actual printing width of the whole pattern and the effective printing width of the design.


24. Misregister

Printing process, the maximum value of the register deviation between the colors, including vertical register error and horizontal register error.


25. Wrinkle

The unevenness of the surface of decorative paper is due to various reasons.


26. Missing print

During the printing process, the oil and black in the mesh of the plate roller are not transferred to the decorative paper, resulting in the absence of the decorative paper pattern texture phenomenon.


27. Blade streaks


The ink on the plate is not scraped clean, resulting in the transfer of excess ink to the decorative paper forming longitudinal print marks. Also known as knife wire, ink marks, etc.


28. Doctor blade mark


Due to jumping or unstable swinging of the scraper knife, etc., the printing process appears intermittently horizontal stripes. Also known as jumping knife marks.


29. Torn-off edges

The defective phenomenon that appears on the edge of the paper roll of decorative paper.
