Selecting a Profiling Target
Initial Testing: When first becoming familiar with using Spyder3Print, it will save
considerable time, effort, paper, and colorant, if practice profiles are built at the 150
patch or 225 patch settings.
Which target for which uses? Most newer inkjet printers are quite linear, and offer
similar results at all three target resolutions. Minor improvements can sometimes be
seen in the more difficult near black areas with the 225 patch target over 150 patch
results.
Older, less linear inkjets, as well as many color lasers and dye subs, may profit by
additional patches. For these printers, comparing results from a 225 patch target to
those of a 729 patch target built for the same colorants and paper will show you
whether any improvements are possible from additional patches. Once you are aware
of which target is optimal for a particular printer, you can continue to use that target
for building future profiles for that device.
The Extended Grays target can be added to any color target to build a composite color/
grayscale profile. This can improve neutrality and detail in grayscale prints, but will
only be apparent in color images with large areas of subtle grayscale content.
Changing Target Text: To change the Printer Name and Media Setting text that will
print on your target, click the back button, and insert the new information in the text
entry boxes. Then use the Next arrow to return to the Select Profile Target screen. To
change other target info, depress the Control key while clicking the back arrow, to
return in one step to the Printer Definition page, where all text lines are accessible.
The Skip to Profiling Process button will allow you to return directly to the Select
Profile Target window from this screen.
150 Patch Target: This is the standard target, and produces excellent results for
many printers and uses. It samples the entire printer gamut at a 5 x 5 x 5 matrix, plus
additional patches in the most demanding areas. This target offers larger patches on
standard size sheets, allowing the user to move more quickly between patches, further
increasing speed and accuracy. Typically this target takes less than three minutes to
measure. This target is designed for printing on Letter or A4 paper in Landscape
