Thanks for yor answer. This is very true. You set: 50C 50M 50Y 0K Printer puts eg. too much cyan ink on page, that gets you: 60C 50M 50Y ---> your "grey" is tinted blue! But by todays standards & quality checks not a problem anymore. And most commercial printers print 4 colors in one run; the online printers and newspaper printers have strict color management. > Ivan Winters -- Gru?, Stefan
