BS ISO 16762:2016 pdf download – Graphic technology — Post- press — General requirements for transfer, handling and storage 4.3 Incoming goods inspection 4.3.1 General All incoming packing units shall be free of damage that affects the quality and/or the processability of the goods. Incoming intermediate products and raw materials may show visual defects and or defects affecting their subsequent processability. They shall therefore be inspected with respect to obvious defects. These include surface modifications (smudging, carboning, scratches, abrasion, set off, etc.), non-flatness (waviness, curling, etc.) and damage (wrinkles, holes, etc.). Prior to processing of such damaged intermediate products, the supplier or the customer shall be informed in order to decide on further steps. This communication shall be undertaken if obvious damage is detected during or after the post-press operation or if there are difficulties encountered with the actual operation. All communication shall be documented in the job information. 4.3.2 Presentation Raw materials should be presented in a way to avoid unnecessary preparative operations. Materials intended for automated feeding shall all be of the same size and aligned squarely and parallel to each other on the leading edge. Specific requirements for automated feeding should be communicated prior to production. 4.3.3 Package identification The presentation of raw materials should be clearly identified with the relevant specification and batch numbers on the package label. This should include the quantity or weight information where appropriate. Where products or raw materials have a specific shelf life, the date of manufacture and expiry of the shelf life shall be clearly marked on the packaging. The wrapping shall be free from any significant damage. 4.3.4 Storage and handling Materials that are used in post-press environments shall be appropriately stored to prevent damage and contamination. The materials shall be used within the period of specified shelf life. 4.3.5 Temperature and humidity adaption Raw materials should be left in an environment of similar temperature and humidity to the rest of the production procedure until temperature equilibrium has been reached. Hygroscopic materials like paper shall be temperature equilibrated and climate stable wrappings should only be removed if the relative humidity of the environment is within ±10 % of that of the paper. Deviations from this requirement shall be communicated to the supplier and/or customer. 4.3.6 Size and squareness tolerance (sheets) The materials that are presented in piles of sheets shall be square and of the correct size as marked...
