5. Storage Condition & Shelf‑life
表格
| Item |
Description |
| Storage temperature |
15‑25 ℃; avoid temperature above 30 ℃. High temperature causes coating degradation and fogging. |
| Relative humidity |
40‑60 % RH. High humidity leads to aluminum‑edge oxidation and mildew. Keep away from condensation and water sources. |
| Light‑proof requirement |
Keep original black inner bag and carton well‑sealed. Consume promptly after opening. Avoid direct sunlight and intensive UV fluorescent light. Short‑time handling under normal workshop light is allowed, do not leave plates exposed for long periods. |
| Shelf‑life |
18 months under unopened original‑package and standard storage conditions. |
| Stacking requirement |
Store flat. Do not bend or apply heavy pressure to prevent corner damage. |
Important note: Use within 2 months once opened. Oxidation white spots on plate edges indicate invalid storage.
6. FAQ
Q1: What is your MOQ? A: Regular order: 50 pcs or 100 pcs per carton. Test samples are available. Sample freight is on customer’s side and can be deducted from bulk orders.
Q2: What is your delivery time? A: In‑stock items: ship within 3 working days. Custom sizes / special specifications: approx. 20 working days upon receipt of advance payment.
Q3: What customization options do you provide? A: Custom cutting sizes, OEM private‑label packaging. Roll format / sheet format, interleaving‑paper selection and custom carton solutions are available.
Q4: What logistics options are available? A: International courier: DHL, FedEx, TNT, UPS, EMS. Sea‑freight or air‑freight for bulk cargo. Domestic trucking available. Payment terms: T/T, Western Union, Paypal.
Q5: Is plate baking mandatory? A: Baking is not necessary for short‑run jobs with conventional ink. Baking is strongly recommended for UV‑ink applications or runs exceeding 200 000 impressions to extend press life.
Q6: Which printing presses are compatible? A: Suitable for all sheet‑fed and web offset presses for commercial brochures, books, newspapers and packaging.
Q7: Scumming or dot loss occurs during printing? A: Check the following points: ① storage temperature & humidity; ② CTP exposure energy; ③ processor temperature / time / developer concentration; ④ water‑ink balance on press.
