Calibrating Epson R-800

[Juan Miguel Jusdado <jusdado@teleline.es>]

Hello to all.  
I am planning to use PDN System to gauge my Epson R-800 and to print b&w 
it has more than enough watercolor paper. The calibration would be 
carried out this way.  
1. - to open up in Photoshop the TonalPaletteInkjett 101 steps.  
2. - to invest to negative.  
3. - to print on the watercolor paper that I will use when it primes the 
final images.  
4. - Escanear the result.  
5. - to measure each step. The same as if it was gauging a negative.  
6. - to write down the result in the Grill - TO - of the Leaf Excell.  
7. - this will calculate me a Curve of Photoshop that I will keep with a 
name.  
8. - to repeat the step 1. -  
9. - to repeat the step 2. -  
10. - to apply the Curve.  
11. - to print the TonalPaletteInkjett 101 steps with the applied curve.  
12. - Escanear and to measure.  
13. - to check results.  
If everything has been OK. To open final image in Photoshop, to apply 
the curve and to print. He/she would have good results. Is it this way?  
I would like to know their opinions.
