I've created some works in CorelDraw X8 and exported them as JPEGs for submission and it was required that all images must be in CMYK format. I was about to email them when I noticed that the colors had gone wrong (see image below). Concerned that there must've been an error in the program, I've reset CorelDraw X8 to the default setting but the results were still the same. I've asked a colleague to open the CMYK Jpeg files for me using a popular photo software program and the colors were fine and correct, even though the thumbnail showed otherwise.
This somehow happens only with CMYK files. I've tried exporting them in RGB format and both the thumbnails and image file were fine.Can anybody tell me what's going on, and how do we fix this? I want to make sure this issue won't affect the files once I've sent them.
Windows PhotoViewer works on RGB, then it was not about CorelDRAW. If you open the file with Photoshop or any other similar program the file should work fine. Also, other image viewers could display CMYK colors correctly
Ariel is right. Looks like this might be a Windows issue and not a CorelDraw issue. I'll see if there might be an issue with my monitor's color profiles. I just bought a new monitor days ago and I think there might be a connection to this.
I do't believe that was relative to your monitor, however I found this article: http://www.tek-tips.com/viewthread.cfm?qid=1697511
Have you tried to open the JPG with any internet browser such as Internet Explorer, Chrome or Firefox?
I think I found the culprit:
Window's default color system profile had changed somehow and it was set in Agfa: Swop Standard. Not exactly sure how but I've changed it back to system default. After a brief refresh, the files are now back to their normal colors.I'm guessing now that this might've been caused by a virus or some sort so I'm doing a thorough scan just to be sure. Thanks for your help, Ariel!
