A PRINTER
i1Match has the capability to profile both RGB and CMYK printers;
however the Eye-One Photo package only has the RGB option enabled,
allowing it to profile inkjet printers such as the Epson Stylus
Photo series which pretend to be RGB devices as well as true RGB
printers such as the Fuji Pictrography series.
The first step is to select the printer you wish to profile and
the type of test chart you wish to use. Clicking the 'Print Chart'
button sends the chart to your printer, but before doing so it’s
essential to make sure that all colour management or optimisation
options are turned off so the chart is printed in the raw colour
space of the printer. You also have the option to reload data
from a previously measured chart to recalculate a profile.
Next you calibrate the Eye-One by placing it on the calibration
plate.
You now use the Eye-One to measure the printed chart. There are
two possible ways of doing this:
-
'Strip Mode' allows you to scan a complete row on the chart
in one go using the scanning ruler – you place the ruler over
the appropriate row and run the Eye-One along it, taking approximately
five seconds to make the complete pass.
-
'Patch Mode' requires you to position the Eye-One over each
patch on the chart individually.
As
you complete the measurement of the rows or patches the display
of the chart progressively fills in.
Once you've completed measuring the chart, i1Match gives you the
option of saving the data.
i1Match now has the data it needs to calculate the profile.
Finally, i1Match saves the resulting profile to the Windows profile
directory and gives you the option to make it the default profile
for the printer.
