I am making a new catalog and want to be able to copy and paste color swatches from one indesign cs6 file file to my new one (also indesign cs6). The copied content contains 4 linked images placed into 4 frames on the original indesign file and a text box with text. I am new to this and keep reading warnings that copy and paste can produce very unwanted results. But when I try it it looks like it has copied over everything correctly and the images are appearing in my linked files window from the paste. I need this content on every page of a long document, if I can copy and paste it will save loads of time. Is there risk to proceeding this way though? Can the content look great and correct on my screen but actually be losing a lot of information/ resolution in the process?
There a much easier and much safer way to bring color swatches from one file to another.
In the file that you're copying to open the Swatches panel. Choose Load Swatches from the Swatches panel menu. Navigate to the file you're copying from, and select it.
The swatches will be copied over and will appear in the Swatches panel, and can be used on all pages.
That's also the way to import styles (Paragraph styles, character styles, objects styles) from one file to another.
You can load swatches as Steve suggests or you can also drag and drop the swatches from the Swatches panel on to the destination document to transfer them. In either case if you have a swatch with the same name, but different definition the swatch will be given a new name (i.e. Red 2).
There's no problem copying and pasting images. If they are linked the link reference gets copied and maintained.
