The use of secondary fibers is quite common during the manufacturing process of recycled papers. Paper quality and the use of energy is so important for the paper recycling process. It is also important to reduce the amount of energy used during this process. For this reason, in this study; during the recycling of the inkjet printed papers, both the standard INGEDE method 11p deinking process and the process without deinking were applied. All handmade sheets and filter pads’ optical values were measured according to T 452 Brightness values (directional reflectance at 457 nm), T 524 L, a*, b* values (45 /0 colorimetry of white and near-white paper) and Luminosity Y values (557 nm, C/2°and D65/2°light sources). Obtained results were compared with each other and shown in graphics.
