I'm trying to develop an InDesign proofing workflow in an effort to get the most accurate colors possible. I'm currently using an Epson WF-7520 inkjet printer. Unfortunately, none of the the color profiles that come with this printer are CMYK. I've been doing some testing, but the combination of paper and inks are getting rather expensive. I'm hoping somebody who has gone through this process can share their expereince and recommendations.
For example, since I'll be sending the printer a printable PDF is it more accurate to print a proof from the printable PDF or should I be printing from within InDesign? Also, are there any decent display/printer color calibrators?
