10.5 IMAGE SIMULATION WITH FUSING AND COLOR MODELS
Once transferred to the paper, the CMYK separations are fused in the fusing process
and then transformed into re
ectance spectra using the equations described in
Section 10.2.6 (Figure 10.50). This process is computationally intense for a full
page image simulation on a 8.5

Digital color printers are capable of reproducing images of different sorts such as
text,
lines, RGB color, etc. To describe the key steps in the full page image
