    • The present invention relates to color matching and, more specifically, an apparatus and method for preparing a stain to match a target color of a selected substrate (e.g., wood species). In one embodiment a system is provided that comprises (i) a computer (e.g., a stand-alone PC or a networked computer), (ii) hardware and/or software to store a database of stain records, (iii) hardware and/or software to create or load spectral data (e.g., a digital image) of a target sample, and (iv) hardware and/or software to display images and/or process spectral data. The system preferably facilities the selection of a desired stain, and in preferred embodiments may also include hardware and/or software to dispense colorant agents and/or vehicles to create the desired stain. The system of the present invention may be used in a "manual" mode (whereby a human compares database and target images and makes a selection); an "automatic" mode (whereby the computer system uses spectral data to suggest a closest match based on the selected substrate); or a "combination" mode (whereby the computer system uses spectral data to suggest a closest match and the user can then compare the suggested match with various images to achieve a final selection).
    • 本发明涉及颜色匹配,更具体地说,涉及一种用于制备染色以匹配所选择的底物(例如木材种类)的目标颜色的装置和方法。 在一个实施例中,提供了一种系统,其包括(i)计算机(例如,独立PC或联网计算机),(ii)存储污点记录数据库的硬件和/或软件,(iii)硬件和/ 或用于创建或加载目标样本的光谱数据(例如,数字图像)的软件,以及(iv)显示图像和/或处理光谱数据的硬件和/或软件。 该系统优选地设计所需污渍的选择,并且在优选实施方案中还可以包括用于分配着色剂和/或载体以产生所需污渍的硬件和/或软件。 本发明的系统可以以“手动”模式使用(人类比较数据库和目标图像并进行选择); “自动”模式(由此计算机系统使用光谱数据来建议基于所选择的基底的最接近的匹配); 或“组合”模式(由此计算机系统使用光谱数据来建议最接近的匹配,然后用户可以将建议的匹配与各种图像进行比较以实现最终选择)。
