Assuming you have a folder of images that you want to convert to CMYK
PRO TIP: If you are not careful when converting images to CMYK in Photoshop, you may end up with an inaccurate color profile. This can cause your images to look different when printed than they do on your screen. Make sure to use the correct color profile for your printer and proof your images before sending them to be printed.
1. In Photoshop, go to File > Automate > Batch. 2. A new window will pop up. In the “Source” section, click the “Browse” button and select the folder that contains the images you want to convert. 3.
Make sure the “Destination” is set to “Save and Close”. 4. Under the “Action” drop-down menu, select the action you want to perform on the images (in this case, “Convert to CMYK”). 5. Finally, click the “OK” button to start the conversion process.
