saving multiple images and changing filename with script/action

OK, the updated code is below, it will save out 3 RGB and 2 CMYK versions of the previously saved and open master PSD image.

I am not 100% happy with the code, however, it is fully functional.

Just to confirm, you originally mentioned a flattening step performed by the action, however, in both the RGB and CMYK workflow screenshots, you are saving a transparent/layered file.

Is that correct, don't flatten in the script... Just accept the natural flattening for formats like JPG and transparency for PNG or TIFF (whether RGB or CMYK)?

/* 
This is amazing!!! This will help me so much!

Is there anyway to automate the rgb file before the cmyk conversion?
rgb_jpg
rgb_png
rgb_tif(optional)

if not it's no worries at all. this itself helps me so much. thank you so much for your effort
*/

Yes, the script can be modified to do everything in your stated workflow. However, before undertaking this I would need explicit instructions...

RGB Workflow:

1. Is there a colour conversion from one RGB ICC profile to another? Example – your main project RGB is ProPhoto RGB, which is fine for the TIFF but for the PNG and JPG you require a conversion to the sRGB ICC profile.
2. TIFF settings, can you show a screenshot from Save as? What exactly do you mean by "optional"...
3. What exact PNG settings, can you show a screenshot from Save as or export/save for web?
4. What exact JPEG settings, can you show a screenshot from Save as or export/save for web?

CMYK Workflow:

1. What CMYK ICC profile and conversion options, can you take a screenshot?
2. TIFF settings, can you show a screenshot from Save as?
3. What exact JPEG settings, can you show a screenshot from Save as?

The previous script saved out the files with the rgb_ prefix changed to cmyk_ 

However, an alternative approach is to simply duplicate the source file with the desired cmyk_ prefix + variable file name and then use an action for everything else. You would need to record the execution of this script into your action.

#target photoshop
var origDoc = app.activeDocument;
var newDocName = origDoc.name.replace(/^rgb_/, 'cmyk_').replace(/\.[^\.]+$/, '');
origDoc.duplicate((newDocName), false); // true to flatten
origDoc.close(SaveOptions.DONOTSAVECHANGES); // close the original doc without saving

OK, here you go, give this a try on copies just in case something goes wrong.

You will have to change the action set name and action name on line 15 to the appropriate flatten and CMYK conversion action.

You can record the running of this script into an action, then you should be able to play a single action to create all of the required files from the original master file.

Please let me know if anything needs adjusting, however, I believe that this is what you are looking for.

EDIT: I have just re-posted the original script as the CMYK TIFF was converting to 8 bpc when it should have been 16 bpc.

I just read your post again, it looks like a custom script is required if you need to change the filename prefix from _rgb to _cmyk – however one could still use Image Processor Pro and just have a dupe/rename script and still leverage IPP for the saving (which can be recorded into an action etc).

Are you all good with the RGB files and it is only the CMYK that need work?

I have mostly completed a custom script, however it is not clear to me on the following in red:

rgb_filename.jpg

rgb_filename.png
rgb_filename.tif
then flatten all layers and convert image to CMYK(created an action for this)

then save to:

cmyk_filename.tif

cmyk_filename.jpg

So the rgb side is all good, nothing needed in the script, is that right? Or do you also need the script to save these formats as well?

You made an action for the flatten and convert to CMYK... What about 16 bpc to 8 bpc, easy enough to add an action step...

At the minimum, the script will rename the prefix of rgb_ to cmyk_ and save the TIFF and JPEG versions... But what file format options (LZW, ZIP etc)? Where will the files be saved (same folder as original file, different location, to a sub-folder etc)?

Finally, the original layered RGB files are being flattened and converted to CMYK, do you just wish to close down the original files without saving over the top of them (as you would no longer have layers or RGB).

A custom script can be created, as an action can't change the filename. More info would be required about save options/methods and output locations... however, there is another option! Using the Image Processor Pro script, you can save multiple images in different formats with different names and actions etc. The great thing is that as this is an automation script, it can all be recorded into an action (the step will record blank but all settings will be included). Then the action can be run from a keyboard shortcut etc.
