Not necessary. When you convert to the printer space using absolute colorimetric rendering the a darker, yellower paper color of SWOP3 will be simulated. When there is the possibility that a range of print conditions will need to be simulated, it is convenient to choose a proofing paper that is comparable to or brighter than the brightest press substrate likely to be used as the target. A bit of extra bluishness is good as well, as simulating warmer papers uses mostly yellow ink, which doesn’t darken the print much. The same is untrue of simulating bluish, brightened stocks, with the result that the result may be noticeably too dark. In my view, GRACo2006-matched papers have neither the brightness nor bluishness to be versatile enough for most commercial shops. Mike Strickler MSP Graphic Services

Hello -

I am looking for some advice. I am doing some proofing for a client, and originally was going to cross render to GRACoL coated so I ordered and profiled *Epson **Standard Proofing Paper (240)* for my printer.

Now the client would like to go to SWOP 3 (after consulting with their print house).

Should I order some Epson *Standard Proofing Paper SWOP3* or can I stick with the first paper (GRACoL) and cross render to SWOP 3 instead of GRACoL?

Thanks!
