Thanks for the reply.
Please bare with me as I’m new to color management and still not familiar with some of the terminology and processes.
Right now prepress is working in one of the printer’s working space. If they get a file that is tagged they convert it to the printer working space. Then the RIP converts it to another profile if it is for a different printer.
This process works okay but I think we may be able to get better results with another workflow. I see two potential problems with the current workflow.
1 - Neither printer color gamut completely envelopes the other. So no matter which working space is used there will always be some colors clipped.
2 - If we need to change the profile or use another for different substrates then there is a lot of work updating and configuring the prepress work stations.
So I thought it might be metter to work in a consistent, large gamut working space. I don’t know much about the different generic profiles but I read ProPhoto RGB was large, so I thought that might be a good choice.
Any recommendations for a default RGB working space? Or would it be better to convert in prepress to CMYK? (It seems that the RIP preserves the color better if it handles the conversion)
Any pros and/or cons to my proposed workflow?
Some more info:
The printers we use are: 2 grand (super-wide) format digital ink jet printers with 16’ platens and 1 wide format ink jet printer with a 64’ platen. The ‘proofer’ is an HP3700 laserjet.
By the way, I am not familiar with GRACoL 7 but will look into it.
Thanks!
