Thanks a lot Roberto for your help

I guess it could be the brighteners, cause the paper is a glossy paper for photography, about the software that came with the pulse, it let;s me edit my profile and is very similar to Monaco Profiler, but I;m not sure if I can edit only one side of the conversion table.

When I use the softproof, it looks great, and it doesn't moves too much from the original, and after I edit my profile with this software, it start giving me a bad softproof.

Right now I see my soft proof picture and it looks incredibly close to the original image, and when I print it it turns yellowish, and if I correct my output profile, I can fix the difference betwen the original and the printed example, but then I go and check my soft proof and it's really far away from what i print. Maybe is better to not use the soft proof? or where is the option which let me edit just one side of the conversion in the profile???

I can take a look in Monaco Profiler, we also have it, but I was trying to learn everything about Pulse

Thanks in advance!!!!

The yellow cast on a printout is typical of a proofing paper with
excess optical brighteners. The instrument sees this paper as "blue"
instead of white, and the profile reflects that. So when the profiling
software builds the profile, it substracts this "blue" color (all
profiles are internally built as relative colorimetric, paper white
substracted). By substracting too much blue, it turns yellow.

The solutions are to either use another paper, or use a UV-filtered
instrument, or a profiling software that can compensate for this, such
as PrintOpen or ProfileMaker Pro. I do love Monaco Profiler, but this
is one (lack of optical brightener correction) is a shortcoming it
has.

If those solutions are not available, you might also try using
relative colorimetric to the printer, to see if that brings you closer
and the amount of profile correction you have to do is less. The
profile you have to edit is definitely the printer profile, but you
may want to edit only one side of it. I mean, if your unedited profile
gives you a good softproof but a bad printout, you may want to edit
only the B2A side (pcs->device, or typically Lab->cmyk). The editor in
Monaco Profiler allows you to do this, I'm not sure if the one in
Pulse ColorElite is exactly the same.
