What Data for This Category Looks Like
This category of data covers the entire production process of color printing, label, carton, flexible packaging, and pharmaceutical packaging enterprises. Daily documents include pre-press files, imposition sheets, printing process sheets, ink color matching records, first-piece proofing signatures, barcode inspection results, die-cutting and lamination records, and more. Data sources include customer manuscripts, color management systems, printing press operation data, ink and substrate batch records, spectrometer and barcode detector output results. Updates are synchronized per order, per batch, or each time a plate is changed.
Constraints on Multi-turn Dialogue and Prompt Engineering for This Category
Data for this category is updated frequently per order, batch, or plate change. Multi-turn dialogue must limit the range of contextually linked historical data to avoid calling expired ink batch or imposition information. Document fields vary significantly, so prompt engineering must clearly define query rules for pre-press files, process sheets, and equipment operation logs. Errors directly lead to full batch scrap, so multi-turn dialogue must include confirmation steps to avoid misprints, unqualified barcodes, and other issues caused by single question-and-answer deviations. Equipment inspection data mostly comes from real-time sensors, so dialogue must support quick retrieval of the latest printing press operating parameters.
Configuration Settings
These configurations are based on FastGPT v4.17.0.
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
chatId | Bind to the current production batch ID | Distinguish dialogue contexts for different orders to prevent cross-batch data mixing |
messages | Retain the most recent 3 interactions | Match the average number of interaction rounds for single-batch processing in this category, reduce expired data loading |
variables | Bind to pre-press file ID and printing press number | Accurately link exclusive documents and equipment data for current production |
| Maximum context length | 800–1200 characters | Match the average length of core documents for a single batch, avoid loading redundant content |
| Question optimization switch | Enabled | Split complex inspection questions into sub-steps to adapt to multi-link verification of printing processes |
| Maximum reply tokens | 1500 tokens | Accommodate complete maintenance steps and equipment parameter descriptions |
Three Common Misconfiguration Issues
- Phenomenon: The preset quick buttons for inspection questions are not displayed in the dialogue interface, and users must manually enter full questions. Cause: No category-specific quick button group for high-frequency questions is configured in the dialogue opening, and common inspection and maintenance questions for the printing and packaging scenario are not bound.
- Phenomenon: Pre-press files or imposition sheets cannot be uploaded when calling the dialogue API, and the interface returns parameter errors. Cause: No file upload permission is configured for the dialogue API, and the business requirement of uploading process documents for this category is not adapted.
- Phenomenon: Users cannot view historical dialogue records in the login-free scenario, and the interface returns an empty historical list. Cause: The unique identifier of the user's current production batch is not bound via
chatId, and the association rule between sessions and production tasks is not configured.
How to Verify Correct Configuration
- Launch a test dialogue, enter an inspection question related to the current production batch, and check whether the returned result links to the exclusive data bound by the preset
variablesparameters. - View the dialogue history list, confirm that only interaction rounds that meet the configuration requirements are retained, and no expired production data is loaded.
- Trigger the preset quick buttons, confirm that exclusive inspection and maintenance questions for the printing and packaging scenario can be sent directly.
- Call the dialogue API to upload a pre-press file, confirm that the interface can normally receive and link to the session corresponding to the current
chatId.
