摘要：We have proposed an improved color control method for a projector-based color simulator.We use low dimensional response,which is measured with an RGB colorimetric camera to estimate spectral reflectance.In our previous work,a color simulator with a projection image was controlled color change on the basis of the ink supply.By overlapping the controlled projection image based on the spectral reflectance,this simulator helps operator to adjust the color of print more accurately.However,measuring the spectral reflectance from every point on print is expensive.To decrease the cost of spectral measurement,we propose a way of estimating method for spectral reflectance.Only three bands responses were used to estimate the spectral reflectance for the projector-based color simulator.The projection image calculated by approximate spectral reflectance reproduces the color change of the print instead of ink supply.Our color simulator with a projection image matched color accurately;for 32 samples,the average color difference ΔE^*₉₄=1.05 and the maximum color difference ΔE^*₉₄=2.58.
