RGB to CMYK

[pg3d]

I was asked the question on another forum regarding converting rgb images to cmyk and I did not have answer for her so I thought I would throw it out here. She has 690 rgb images, yes 690, that she wants converted to cmyk done in a batch process. She attempted some trial images in photoshop, but she said the color was too far off. She is looking for some way to make the conversion through some type of batch process does anyone have any recomendations? Because of the volume she talking about I am at a loss.

Thanks

Batch processing is the easiest and fastest, but there's no control over color shift. She already has the 2 critical things that are needed...her eyes! That's about the best way. Then she might save a curve, putting like images together as a batch and see how close they come. An unenviable task.

First of all make copies for backup. Second, Rick has it right, the best way is to go through them one by one, convert, checking the color levels, making adjustments. It will take a while.. 690? wow. I say about 1 every 15-20 min. depending on the other problems with the images.

Try to make use of the "Record Actions", so when the next image is opened, the recorded action can be used, and maybe very little adjustments need to be made. Most of the time the record actions will save alot of time.

If you can make an action list record out of the conversion process, you can
save it as a Droplet. Save that Droplet, then drag and drop the files onto it
one at a time or many at once. The action will need to include where you
save the new file to after the action has ran. If you can get it to work it
could come in handy for future use, too. You'll need to be careful because
everything you do to the original file as you create the action will be recorded and
duplicated in subsequent files.
