Orders that split across sheets — avoid wasted film

A large order can need several production sheets because of usable width, file handling, cutting, sorting or delivery requirements. Decide how to divide the approved artwork and quantities before exporting. Then compare the total film area and operator work for the candidate arrangements using your own job record.

This is a manual batching procedure for preparing several sheets. It gives the operator a way to connect source artwork, placed copies and completed production files while comparing layout and finishing needs.

Establish the actual production constraints

1. Printable width. Use the width supported by the loaded film and receiving printer setup.
2. Manageable sheet length. Check the file, queue, film handling and finishing process used by the shop.
3. Individual transfer size. Compare each transfer with the intended application equipment after the pieces are cut from the gang sheet.
4. Cutting and sorting. Leave room for the actual cut path and identify how pieces will return to their order groups.
5. Delivery format. Agree whether the customer receives intact sheets, cut transfers or applied garments.

Record each constraint with its source: equipment documentation, a tested shop procedure or the customer’s order. Choose sheet dimensions that satisfy the complete production path, then keep individual-transfer requirements alongside the layout record.

The three split strategies

Given a total packed area A and a per-sheet cap C, you need at least ⌈A / C⌉ sheets. That is the theoretical floor. The strategy question is which items go on which sheet — and it drives how close you get to that floor. All three strategies below are things you do when batching the order, not switches you flip: pick one deliberately, group the artwork accordingly, and nest each group as its own sheet.

Strategy 1: Fill-then-spill

Fill the first sheet as tight as possible. When the next item will not fit, open a new sheet and continue. Repeat until all items are placed.

• Best case: close to theoretical minimum sheets.
• Worst case: the last sheet has one or two pieces and a lot of blank film. You pay for the whole sheet even if 80 % is empty.
• Right for: small mixed orders, low item count, low visual uniformity (the customer will not notice piece-to-sheet layout).

Strategy 2: Balanced split

Divide all items into N piles of roughly equal area where N = ⌈A / C⌉, then pack each pile onto a sheet. Every sheet is similarly full.

• Best case: consistent sheet-to-sheet density, no wasteful tail sheet.
• Worst case: if items have very different sizes, the packer cannot hit the density of Strategy 1 on the tight sheets.
• Right for: large orders, items of similar size, customers who care about the visual of the gang sheet itself.

Strategy 3: Group-by-kind

Put all items of the same design on the same sheet (or adjacent sheets if the quantity exceeds one sheet). This ignores density optimisation for a logistical win — it makes reorders trivial and it makes partial fulfilment (say, 80 % of the order shipped today, the remainder tomorrow) straightforward.

• Best case: cleanest post-print workflow, easiest for the operator cutting and bagging.
• Worst case: lowest utilisation of any strategy; you pay in film for the shipping/reorder benefit.
• Right for: wholesale orders, recurring designs, customers who pay for the handling benefit.

Compare the strategies on the same order

Build candidate layouts using the same approved dimensions and copies. Record the total film area across all sheets for each candidate, then reconcile every piece against the order. Price the measured area difference using your actual film cost.

Also record the cutting and sorting work. Grouping by design may help one order while balanced batches help another. The actual artwork mix and finishing requirements determine the useful arrangement.

Keep the candidate sheets and observations so the next operator can repeat the comparison. The order-reconciliation worksheet provides a record for sheet assignments and remaining copies.

Where the split lines actually go

If you decide to split by area rather than by kind, there is one more trap: the cut line should not cross artwork. Even millimetre-accurate cutters leave a kerf. If a cut happens through the middle of a design, that design ships with a sliver of the neighbouring piece still attached, or with a sliver trimmed off its own edge.

Since you are placing the cut by hand, make the film give you room for it: the piece-to-piece gap exists for separating transfers, not for cross-sheet cuts (in NestSheet it defaults to 2 mm and is adjustable per job). When you know a long sheet will be cut apart, either nest it as separate per-sheet batches from the start — then every sheet boundary is a clean edge, no mid-film cut at all — or widen the gap enough that scissors or a blade pass between pieces without grazing either. Beautiful utilisation with a cut through a back print is not a saving; it is a reprint.

Prepare and export each sheet in NestSheet

1. Choose the sheet dimensions and spacing for the actual production process.
2. Add the approved transparent PNG artwork for that batch and set its sizes and copies.
3. Use Auto-nest or Manual to arrange the sheet, then check every placed piece.
4. Choose the whole-sheet white choke and export the Production DTF preset for MainTOP.
5. Record the downloaded TIFF beside the pieces assigned to that sheet.
6. Repeat for the remaining quantities and reconcile the completed order.

Keep the source revisions and quantity record with the production files. If you revise a sheet, identify the current TIFF clearly before handing the batch to the receiving operator. Follow the MainTOP export checklist for the final file review.
