The decor paper is a crucial component in laminate papers as it provides the visual appearance to the laminate. Its role is to give the laminate its desired color and design. However, achieving the perfect color on decor paper is a complex and challenging process.

One of the key factors in creating the desired color on decor paper is the refraction index of the impregnating resin and cellulose. These two materials have similar refraction indexes, which means that the fibers in the decor paper appear transparent after lamination. As a result, the shade of the paper deepens significantly and only the pigments and dyestuffs remain visible.

Color perception is highly sensitive to the human eye, especially when it comes to large exposed surfaces like decorative laminates. This makes dyeing decor paper an extremely difficult and critical task. To cover the body of the laminate, a large amount of pigments is required. Pigments with a high refraction index, such as titanium dioxide, are particularly effective in achieving the desired color intensity. As a result, decor paper typically contains at least 20% and sometimes even up to 40% or more of titanium dioxide or other special pigments.

Decor paper is manufactured for white or colored decor, often imitating wood finishes. This means that there are numerous variations of colors available, including different shades of white. However, creating these colors is even more challenging as they can only be seen after lamination. Therefore, when adjusting the color, a sample must be drawn from the paper machine and laminated in the laboratory before the final result can be judged.

The production of decor paper becomes more complex and costly when dealing with small lots and frequent color changes. The ability to change shades quickly and efficiently becomes a significant cost factor in the manufacturing process of decor paper.

In conclusion, the decor paper is a vital component in laminate papers and plays a crucial role in providing the desired color and appearance to the laminate. Achieving the perfect color on decor paper is a challenging task due to the refraction index of the materials used and the sensitivity of the human eye to color differences. The use of pigments with a high refraction index, such as titanium dioxide, is essential in achieving the desired color intensity. Creating different colors and shades is even more difficult as they can only be seen after lamination. The capability of changing shades efficiently becomes a major cost factor in producing decor paper, particularly when dealing with small lots and frequent color changes.
