Hi Riccardo,
Apart from the fact that a lot of different things could be the cause of your
problem -what paper are you using, what about original, overexposed print, ink
not stiff enough etc. etc.- I can tell you the following out of own experience:
- the soaking before inking : make the water soapy with a non smelling
oldfashioned hard soap (you can use this also for cleaning the brushes) and put
the matrix in it for a few minutes,
- rinse the matrix very good to avoid a n y remaining soapy film on it,
- inking with the brayer with ink as stiff as possible (if not stiff enough add
some pigment powder or magnesium carbonate)
- use two 5 cm foam brayers, one for the inking and one to clean highlights
- after inking you can:
1. spray water over the matrix (see the thread 'Dahliamisters' or use
ordinary plant spray device) and go over the matrix with the second clean
brayer.
or:
2. use a watercooker to cook water and hold the matrix face down in the steam
of the water and use your second roller
or:
3. try with a fine sponge to rub under water. Terry King told me this and I
will try this one.
Methods 1 & 2 I tried , also with succes , thanks to pete F. and Klaus P., but
the results with a clean brush used after brayer preparation are more
promising.
Remarks :
- I have the impression that an overload of ink with a brayer is more often the
case, on the other hand is the removing action more heavy with the brayer.
- the rolling of the brayer must be executed beyond the image and can be done
very fast, especially by trying to find your whites back again.
- messing around with partial soaking with ammonia led always to a definite
result, a with white spirit created virgin matrix.
Hope this helps
Regards Henk
