How to check yellow variation on the press
Pull one sheet and measure the yellow solid against another sheet from the same batch. Do not judge yellow by the screen. Follow the job ticket.
Pull one sheet, measure the yellow solid, and compare it with another sheet from the same batch. Do not only look at whether yellow looks bright on the screen. For yellow variation, follow the job ticket, not the shift's memory.
Check order on the press
Yellow ink is sensitive to the backing and to wet or dry. Do not pair a wet yellow with a dry yellow to force this 5. If these conditions do not match, do not start the pass call.
Check
| Item | Do this | Do not |
|---|---|---|
| Yellow variation | Pull one sheet, measure the yellow solid, and compare it with another sheet from the same batch. Do not only look at whether yellow looks bright on the screen. For yellow variation, follow the job ticket, not the shift's memory. | Only a feeling |
| Common miss | Do not skip yellow because it looks faint. If yellow is out, skin tone and the brand colour both shift. | Stick with the wrong call |
| What to keep | The report needs yellow on its own line. Do not write only that cyan, magenta and black passed. Note wet or dry. | Only the word pass |
Check when the job changes
- Put yellow on its own line.
