For industrial fabric, the color difference is usually more tolerable than civil products, it is normal for visible difference between batches to the naked eye(1<δE<2). Glossiness contributes to chromatic aberration as well, even the 2 sides from the same piece fabric appear to be different due to the luster of the roller surface.

Usually we do not accept trial (making samples) due to large MOQ of the raw materials.  In cause that both base fabric and PVC available, we can do trial with certain charges which will be credit to balance payment of the massive order.

1. Defects in raw materials
2. Unexpected faults and wastes during production

The ratio of quantity difference and non-standard rolls is inversely proportional to the order quantity, that is, the larger the order quantity, the smaller the proportion. If the production separate into several times the percentage will be higher. According to our statistical data, the proportions corresponding to different widths and roll lengths can be referred to the following table:

Width M	Length M	Qty M	More-or-less	Short rolls
1.0-1.6	25-50	3000-5000	10-15%	20%
1.0-1.6	50-100	3000-5000	10-15%	30%

More-or-less % by SQM = （Finished Qty-order Qty）÷ Order Qty Short roll % by Roll Qty = Short roll÷total roll No. Different color, thickness, base fabric should be calculated separately

The fading speed can be limited to a certain extent by light stabilizers, ultraviolet absorbers and the light fastness can reach level 6 or 7, but we cannot guarantee 100% no fading, especially the brighter the color, the easier it is to fade.

Long term exposure to sunlight leads to the degradation of plastic

materials. The complete solar UV spectrum ranges between 280 and 400 nanometers, but the most aggressive part is the UVB range with very short wavelengths between 280 and 315 nanometers. UV radiation represents only 4.6% of the solar spectrum but causes the most important damage to the polymeric materials. This is call photo-degradation, a process that generally results in breaking down the polymer chains. This frequently results in a deterioration of the physical properties, changes in color or chalking of the part surface. The irradiation is the radiation energy incident over a specific area for a given period of time. It is expressed either in W*s /m2, Joule/m2 or very often in Langley (Ly).

1 Ly = 1Cal/Sq.cm = 4.185 Joule/SQM

The global annual sunlight radiation level (kLy/year) for various

countries is given in the table below. values in this table are only indicative. In some large countries including China, radiation levels can vary significantly from one area.
