Visually comparing the printed color
Use a light box to compare the printed sample color to the target color. The light standard
should be identical to the standard that you chose in "Selecting a PANTONE
®
color" (step

If you are satisfied with the color match, you can select Additional Cans on the hp
IndiChrome window, which supplies the ink weights for 500 g cans.
If you are not satisfied with the color match or if you want to determine the
spectrophotometric results of the print, proceed to the next section “Adjusting the ink mix
from the printed output.”
