test PDN system



Hello to all. I have begun to prove PDN System with process of silver jello. 1. I have determined the Normal Time of Impression (for paper and chemistry). 24 seconds. 2. I prime the Palette of the Range of Density of Color with the Normal Time of Impression and I don't have any square of pure target of the paper. Although the clearest tone is that of the combination of G+R. 3. In the printer Epson R-800, I have configured to go up the level of the inks Cyan and Yellow, (+12 Cyan +12 Yellow) and a second Palette of Range of Density of Color with +25 Cyan + 25 Yellow that is all that allows me my printer. 4. With these new Yokels of Range of Density of Color, I have carried out a new impression of each a (with the same Normal Time of Impression, paper and chemistry). Result: In the Palette's of Range of Density of Color impression (+12 Cyan +12 Yellow), you grieve it can appreciate the difference with the Palette of Range of Density of Color (0,0,0). In the Palette's of Range of Density of Color impression (+25 Cyan +25 Yellow), it shows two pure almost white squares that are: R255G90 AND R255G100.
The target that shows this impression is not exactly the target of the paper, let us say that it is a lightly colored target of gray.
He/she asks. that I can make to get more density and to produce the pure target of the paper?.
As it could go up the tests escaneds without making it like I annex to the e-mail.?
Thanks to all.
