Title: Printing White 'Color'
Post by: davidh202 on June 04, 2011, 11:22:13 am

 Really dumb one here...

    I have a poster I created with a white border background. White values in CS5 are 255 each in RGB.
Does the printer create a process white from the ink, or does 'white' simply become the paper white with no ink used to create the color'white'?

You cannot get any whiter that the paper white. No inks are capable of creating a white whiter than the paper.

What some people do is pull 255 down to about 250, which forces the printer to print a very faint pattern. This helps to reduce gloss differential, which is seen when there is no ink laid down in a blank area.

Some printers (HP) can print a gloss coating over blank areas so as to avoid gloss differential.

Brooks Jensen wrote a good article on this, titled "Chasing Highlight Tones". You can find it at http://technology.lenswork.com/2010/04/chasing-highlight-tones.html.

Well, depends on the paper.  Epson Stylus Pro WT7900 has white ink.
