Can I get a proof before printing name labels?

Yes, and the proof is worth a slow read on a name label order, because a misspelled name is only obvious once the batch is printed.

• Text and spelling: check every name character by character
• Colors: confirm the CMYK conversion held your artwork
• Layout and trim: important elements stay inside the trim and bleed lines
• Size and orientation: match the label to what it is going on

The press waits for your approval, so nothing is locked in until you send it back.
