Abstract

Mimetic chromatic reintegration in easel paintings is usually achieved by levelling the surface of losses (lacunae) with a white filler, followed by its retouching with an appropriate paint. This investigation aimed to understand how different formulations of fillers (colored fillers and white fillers covered with three kinds of paints: watercolor, gouache, and mastic resin) influence mimetic reintegration. Colorimetry, using a smartphone with a color measurement application, and Fiber Optics Reflectance Spectroscopy (FORS) measurements were made on 29 samples of fillers and on the surface of the pictorial layer of our case study - a painting by Veloso Salgado.The combined use of these techniques allowed us to choose the most similar material filler system. The pigmented fillers gave us the best results to perform a safer and faster chromatic reintegration procedure. This procedure appears to be suitable for contemporary art as which usually do not present a protective layer. Also, the use of pigmented fillers simplifies the color achievement.

填料对架上绘画色彩重新整合过程的影响:对肤色的分析研究。

在架上绘画中，模仿色彩的重新整合通常是通过用白色填充物平整损失(陷窝)的表面，然后用适当的油漆进行修饰来实现的。本研究旨在了解不同配方的填充剂(彩色填充剂和白色填充剂覆盖三种颜料:水彩、水粉和乳脂树脂)如何影响模拟融合。比色法，使用带有颜色测量应用程序的智能手机，以及光纤反射光谱(FORS)测量了29个填料样品和我们的案例研究的图像层表面- Veloso Salgado的一幅画。这些技术的结合使用使我们能够选择最相似的材料填充系统。该色素填充剂为我们提供了一个更安全、更快速的着色整合程序。这一过程似乎适用于通常没有保护层的当代艺术。此外，颜料填充剂的使用简化了颜色的实现。
