Colour Bar

What it does

• A colour bar is a measurement tool, not a decoration on the sheet.
• It must sit outside the trim and inside the sheet.
• A bar that is cut off cannot be read during the run.

How to use it

1. Keep the bar clear of the bleed so a trim shift does not cut it.
2. Order patches in the same sequence as the ink stations.
3. Include a grey patch if the job relies on neutral balance.
4. Photograph the first approved sheet with the bar visible.

Safety notes

• Do not place the bar inside the trim area to save sheet space.
• If the sheet is too small for a full bar, use a shorter bar and say which patches were dropped.
