Helo everyone. 

I need some help! 

I'm trying to reproduce a set
of drawins to make copies as faithfully as possible. I have used a grey
card in order to fix colors (wb) and exposition. I figured I could do
that by measuring 127, 127,127 in the card, but the result has been
absolutely unsatisfactory. 

I know I can't control the printer output
as I don't have any specific icc profile, but even the jpg images are
very redish/yellowish, and very clear compared to the originals. The
printed copies were even worse (clearer more saturated and
redish/yellowish). 

I've been looking into the messages and I'm
overwhelmed by all the concepts involved. To begin with, I don't know if
I should disable the base curve, as it tends to add saturation. I don't
know if the input color profie should be linear or not. Then comes the
output color profile "to the rescue": 

output, perceptual?; 

screen
output, ¿?; 

output profile: AdobeRGB?; 

printer profile, a CMYK icc
that I dont have? 

screen profile, OS. 

Then, in lightroom mode,
export, I have another intent (I asume image config will take into
account the adjustments I've already done) and another profile... 

My
simple question is: Which would be the best workflow to produce a
faithful copy of a picture/drawing? 

I hope someone can help me if I
have made myself clear enough (which I'm not sure of) 

Thanks in
advance.
