Project Help Needed

Question

Version of InDesign: CS6
Note: I am a beginner, I have not been trained in any Adobe products, I am not familiar with the tech lingo
I work for a business where we have started using InDesign to create personalized labels for products. I created a file with a simple master page at dimensions of  4" x 3" with the desired template for the label. I then create new masters based on the first one I made and then edit the layers as needed. I have four base files with about 200 'product specific' master pages in each. I have to copy these files over about 12 times to create customer-specific labels with logos, retails, etc. That comes to about 10,000 labels total.
The problem is, I have to print these labels off on sheets of paper with 6 labels on each page. Does anyone know of a way I can print the single label master pages off at 6 to a page?
One other solution is to create a new master page "template" with six label designs to a page, which would be very simple to print off. But then the files would be a lot bigger (my computer won't like that) and (I  assume) I would have to bring the information over to the new file by copying&pasting text/relinking images about 6 times for each label.
Does anyone have any ideas that would save me time? Any insight would be greatly appreciated.

Answer 1

There is an excel formula that will calculate the check digit and create a field with the full barcode number. I haven't had to do this in years, so I no longer have it, but it should be easy enough to look up. If you are using the number to place the barcode graphic, you can also add the extension automatically in excel.
Just add a '@ before the column name of any column containing image names. If you put your datafile in the folder with the images, you won't have to put the image path.
