Abstract :This study aims to visually and instrumentally examine the surfaces of particleboards laminated with white decor paper impregnated with α-cellulose-based melamine resin after treatment with five different surface processing agents. Samples of three different types (-A, -B, -C), each with three different grammages, were evaluated according to the TS EN 14323 standard, and color and texture changes were compared. The data were statistically analyzed using ANOVA and the Duncan test. The lowest brightness value (L*: 92.79) was found in samples laminated with 110 g/m² grammage B-type decor paper and treated with water (Wa) and acetone (Ac). The a* color coordinate values were found to be negligible (a*: <1.0), while variations in the b* coordinate were calculated at certain levels. The highest change in the b* coordinate was observed in the acetone-treated surface of the 80 g/m² grammage A-type decor paper (Δb*A80Ac: 0.51), with a difference of 27.4% compared to the control sample. The most significant color changes were found in the 110 g/m² grammage A-type samples treated with water vapor (ΔEA110Wa: 0.61) and the 80 g/m² grammage B-type samples treated with coffee (ΔEB80Co: 0.68); however, these changes were visually undetectable (ΔEB: <0.70). The highest color difference was observed in 90 g/m² grammage C-type samples treated with alcohol (ΔEC90Al: 1.48), followed by acetone (ΔEC90Ac: 1.18) and water (ΔEC90Wa: 0.91). The results indicate a strong correlation between visual perception and colorimetric measurements; however, some marginal differences may be overlooked. This study emphasizes that colorimetric assessments provide more precise results compared to visual evaluations.
