## What causes the bottom pink or goldenrod copy on a carbonless form to come out blank?

Prepress technicians at Carbonless Forms trace unreadable bottom copies to five pressroom defects: inverted CF/CB ply collation (0% transfer), thin 18.5 lb gang-run paper, heavy 240%+ CMYK ink printed over fill-in boxes, missing wrap-around shields on 4-part sets, or stock aged past 24 months.

| Fine at top, fading downward | Writing pressure or part count |

| Whole form faint on all copies | Writing instrument or storage |
| Faint on one batch or season | Humidity and storage |
| Degrading over the run | Plate wear |
