hello
when printing i have this two options,
i have the image at 16 bits and it prints too,
but were is more qualtiy 16 or 8 bits?
Personally I work in 8 bits almost exclusively. But many people choose to work in 16 bits, and then throw away some of that hard earned accuracy by printing using printer color management, which truncates to 8 bits before printing. This results in an 8 bit profile conversion, and significant round off error in the eighth bit. Due to this roundoff, only somewhat more than 7 bits of information actually gets send to the printer.
Can they see the difference? Probably not, and for some this may shed doubt on the utility of working in 16 bits in the first place.
For those who do care, this last "bit" of error may be avoided by manually converting to the printer’s profile, followed by conversion to 8 bits, before printing.
