Re: gamma - BO vs continuous tone

2006-04-20 by Brian Chapman

Thanks for the info!  My goal is to get some consistency across my 
prints/workflow - and you're right on about 'too many workflow 
variables'!!  Assuming that I follow your instructions/settings 
exactly then there shouldn't be a significant difference between BO 
and full ink when using Gamma 2.2, correct?     

As for my initial issue, the one potential (and potentially 
significant as you mentioned below) issue is that I may or may not 
have converted the image to grayscale prior to printing - and 
therefore the image could have been using Adobe 1998 instead of DG20 
which may have made a difference between the two ink settings (BO & 
full ink). 

Thanks again for the great articles and I definately look forward to 
any you publish in the future!!
