Jim, If this is a cast that is slight and affects the highligts the most it could be a UV measurement issue. If the previous profiles were based on measurements that excluded UV, or if the measured paper was different than what you are measuring and was less bluish (e.g., contained less optical brighteners) your present results will be show a yellowish cast in comparison. Also check that you have not changed the refernce profile and rendering intent in your new workflows (Color tab: Color Management). EPLs made in 4.1 should work in 4.5, by the way. Are you sure that the old RIP wasn't 4.0? Mike Mike Strickler MSP Graphic Services

Hopefully someone can help. I'm in the process of up grading our computer that runs our EFIxf rip (ver 4.5.7). The old rip (4.1) produces color fine, but the prints off the new rip have a yellows cast. I'm not using the EPLs from the old rip because they error out in the new rip. So new EPLs and media ICC profiles need to be made on the new rip and that's were we get the yellow cast. I'm using the EFI color management software on the new rip to make the ICC profiles, (for the old rip I use Monaco). I've done the measurements using a DTP70 and a i1 and get the same results from both devices. This is our last Canon printer we have in the shop, we don't have this yellow problem with our Epson printers running through the new rip. Any thoughts on what might be going on would be appreciated.
Thanks Jim ................................................
