there are many software available at online for editing labels..
You can edit a label using label software. I had purchased a label software from RLSLTD. But I didn't understand all functions properly, then I take the support service of the company from where I bought it. So for your problem you can take the support service from where you bought it.
Other people asked questions on various topics, and are still waiting for answer. Would be great if you can take a sec and answer them
