The Toray Thermal Negative Waterless CTP Plate Instruction Manual provides handling, exposure, development, and troubleshooting guidance for safe use.
This manual explains the basic principles and structure of Toray's waterless CTP plate, a thermal‑negative type used in computer‑to‑plate printing. It describes the multilayer construction—including a silicone rubber non‑image layer, a photosensitive image layer, and a protective cover film—and the infrared‑based exposure process.
The document also covers practical handling of unprocessed and cover‑film‑less plates, storage, pre‑treatment and after‑treatment solutions, daily maintenance, and a detailed troubleshooting guide for common issues such as poor dyeing density, silicone peeling, and surface scratches.
| Image area layer | Photosensitive (ink receptive) |
|---|---|
| Primer layer | Allows dot readability |
| Sensitive wavelength band | Near‑infrared ray |
| Light handling | Can be handled under normal light |
The cover film should be removed before exposure and development; doing so improves energy efficiency.
