Does anybody have some info on some standards that one can follow for TVI (dot gain) at different percentages. I come across info for TVI at 50% but I am interested in guidelines for highlights etc. I am runing a DI press and basically get the press to a linear state..ie. 50% dot prints 50% on press. So at my rip I add a dot gain curve so I get the results I want.
At the rip is a stock SWOP curve which produces following results:
5% 20%
Dot gain generates:
K - 14% 36%
M - 11% 35%
C - 13% 33%
Y - 11% 32%
Some technicians a while back put in some new curves with the following:
5% 20%
Dot gain generates:
K - 8% 31%
M - 8% 31%
C - 8% 31%
Y - 7% 28%
I find many screen tints with low percentages seem to print too light so I wanted to increase things but did not know if I should go back to the SWOP standards. I am also trying to run higher densitites so do not know if the SWOP standards would apply. I can fool around and try different values but I wanted to see if any info is out there on this.
Eventually I plan to test out Gracol and strive for Grey balance but this may be a little while yet.
