that optimal printer settings are selected, and that color correction is turned off in the
driver.

: Target Drying
Some devices, such as color lasers, require no target drying time before
measurement. Some inkjet printer, ink and paper combinations are immediately dry,
or offer wet colors nearly identical to their dry colors. Epson UltraChrome inks, for
example, do not color shift during drying and require no more than ten minutes wait
before profiling on most papers. Dye inksets used in a wide range of printer makes
and models do require extended drying time on some papers. The reasons for this
include color shifting, which may render a profile build shortly after printing
inaccurate, and durability, which may mean that the process of running the Spectro
over sections that are not yet dry may damage the target print. In cases where the
target print is sensitive to Spectro contact, placing a sheet of non-sticking paper over
the lower section of the target, and moving it down as the rows are measured, can
improve results.
Drying Times:
Typically matte media require less drying time than luster or gloss.
Pigment inks may require less drying time than dyes. A minimum wait of ten minutes
is recommended in all cases, but particularly sensitive ink and paper combinations
may require as long as two days in humid conditions.
To determine whether drydown is a problem with a specific printer, colorant, and
media combination, measure a medium gray, a bright red, and a dark blue patch
shortly after printing, and note the L*a*b* values. Patches M3, F6, and E1 on the 150
or 225 patch targets would be effective for this purpose. Remeasure 48 hours later,
and compare the results. Variations in L*, a*, or b* of much more than one unit
denote significant drydown changes, and indicate that this media and colorant
combination should be allowed to dry before being measured.
As long as a target print has not been damaged by measuring it wet, remeasurement
