Re: Printing white on black

[Kees Brandenburg <ctb@zeelandnet.nl>]

Hi Loris,

It's a long time ago when I experimented with this.  I mixed an  
acrylic paint in a  normal 3% gelatin solution to get a firm black  
and  brushed it on paper and hardened afterwards. Another aproach is  
to paint your paper (black) with acrylic and than add a normal size on  
top.

An acrylic undercolor was used for these gumprinted portraits: http://polychrome.nl/brandenburg/cv/kunstliefde/liefde.html
... ten years ago allready - time flies

I also did cyano's on colored paper: http://polychrome.nl/brandenburg/cv/distexit/distexit1.html 
 and http://polychrome.nl/brandenburg/cv/distexit/distexit3.html (1994)
A cyano on black paper looks very special! For these I used ordinary  
colored photocopy papers. I had to test a lot of papers: many lost  
their color in the water.
