Approve the sheet your next process actually needs
A sheeting trial is useful when it answers a specific production question. Will the sheet fit the receiving equipment? Is the required grain direction clearly identified? Can the material be handled, printed, or converted as intended? Define those questions before deciding how much trial material to run.
Send the current drawing or specification, the board grade and caliper, and the equipment or downstream operation the sheet will feed. An approved sample should represent the same material and finished format that the production order will use.
Put dimensions and acceptance limits in writing
Specify finished width and cut length with units, then state the acceptable variation for each. Identify grain direction explicitly on a drawing or written specification. Do not rely on an assumed order of dimensions to communicate it.
Include the required checks for squareness, edge condition, flatness, surface appearance, and any coating or print side that must remain protected. Ask how measurements will be made and recorded. A requested tolerance is subject to material and machine review; it is not automatically accepted because it appears on the request.
- Material: supplier grade, caliper, coating, and lot identification.
- Geometry: width, cut length, grain direction, and agreed tolerances.
- Condition: acceptable edges, surface appearance, and any damage criteria.
- Traceability: parent-roll reference, sample identification, and specification revision.
Test the receiving operation and the packaging
A visual sample check may not answer every question. Decide whether sample sheets need to run through the actual receiving equipment before approval. Name the person responsible for that evaluation and agree what information must come back to Bengal.
Review how the sheets will be stacked, protected, labeled, and palletized. Provide pallet dimensions, maximum stack height or weight, counting requirements, and any receiving restrictions. The approved sheet and its handling configuration should both be clear before the larger run.
Keep a clear approval and revision record
Record the sample identifier, specification revision, approval date, and any conditions attached to acceptance. Distinguish full approval from approval subject to a particular change. Avoid releasing a production order with an old drawing while a revised sample is still being reviewed.
If the material grade, caliper, coating, dimensions, or intended equipment changes, ask whether the previous approval still applies. Keep an approved reference available to the people placing repeat orders and receiving finished sheets.
Prepare the sheeting request
Share the incoming roll dimensions, finished sheet specification, trial quantity, production quantity, and required delivery date. Explain whether this is a new grade, a new size, or a repeat program. Those details help the team decide which questions need to be resolved before quoting.
Bengal’s two Marquip sheeters have different size limits. Use the machine matrix as an initial reference and have the complete material and output specification confirmed before sending stock.
