I go through all the trouble of building Spot Channels and Photoshop doesn't always save them. I have to do "save as" and make sure the "Save Spot Channels" box is checked. Which sometimes it is- but at random it is not. I do not know what causes this - but it is infuriating. Sometimes I open my file - the spot channel is gone- but the alpha channels I created are there. Alpha channels take a lot less effort to create and Photoshop saves them automatically- why aren't Spot channels saved automatically. I feel that anything I create should save no matter what. If I hit save- everything in the file should save. Spot channels should automatically save. If I didn't want them there, I would throw them away.
