I have received a batch of calendars from a local commercial printer. The colors are OK, but do not match the originals, especially the blue's. I've had similar problems with greetings cards from a different printer. The problem appears to be that I supply the original files in the RGB color space, but they print using CMYK.
I Raw process using Lightroom 4, with adjustments if necessary being made using Photoshop Elements 10. Neither of these programs have the option of editing or saving in the CMYK color space. For more accurate colors is my only option to purchase the full version of Photoshop (CS6 or CC), then convert and color correct my images in CMYK mode before sending to the printers ?.
Any suggestions would be appreciated.
