Of course that only works if all ingredients stay the same. For my soaps they do not. I formated a 4x2 label that wraps partially from the front to back. Took some doing but the label works great. For rounds honestly the best is outsource or a label printer which are very expensive. $1400+ Sadly my Primera label printer is broken down. They want a flat fee of $250 to fix which is why it is sitting idle so I had to figure out an alternate way to make a label with my laser. I can change my gap settings and margins settings by 0.10 of an inch.
If you go to full sheet labels for anything other than rounds I would invest in a good Roto Trim photo quality cutter. Have had mine for 10 yrs and never changed a blade. When my daughter was getting married I printed her invitations and needed to cut them. One of our employees told me to get a Roto Trim, she is a photographer on the side. I did because at that time I was fortunate enough not to worry much about cost and figured I would only use it that one time. Still using it 10 yrs later and it was a great investment. They come in different sizes. Honestly you can waste a lot of money of cheap rotary cutters and could have purchased a Roto Trim
