I have checked the artwork to make sure they are PRESS READY, that means:
1) All fonts in the artwork must be converted to curves or outlined
2) Use one spot colour setting for the single colour job. Or make C=0, M=0, Y=0, if using CMYK setting.
3) All lines in the artwork must not be less than 0.25pt
4) All transparency effects must be flattened.
5) All Layers must be flattened in one layer.

7) The margin around text to border must be over 5mm for each side.
8) The minimum numbering space for 4 digit: Height 8mm, Width 20mm (Extra 5mm for each additional digit)
