Hi Michael,
Grain usually comes from rasterization. So first you should check
your printer settings.
Linearization is a must with color laser printers. Otherwise you will
end up doing profiles about every day.
For the correct way of doing a profile you should contact your Canon
dealer. It heavyly depends on your product (which CLC, which RIP,
which software release) on how to generate your target prints (pre
profiling) and your GCR/UCR settings.
Perhaps you want to contact a local Color Management consultant.
There is a list of consultants on Apple's ColorSync web site.
Good luck,
Karsten

Hello,
I am trying to build a profile for a Canon CLC color laser
photocopier, and the resulted profile was color accurate, but
extremely grainy.
I didn't linearize because I thought you don't have to for laser
printers.
I have used PM5 with the Laser preset at Separations when I
generated the targets.
Did the grain means that I have to linearize?
Can I fix it with Post linearization or I have to Pre linearize?
Any suggested settings for the GCR / UCR Seperations Dialog (and
where should I use them In target building or in Profile Making)?
Please assist. I never build profiles for CMYK lasers and I am
really confused!
Thank you in advanced.
Michael.
