Scope
This reference documents every field you will edit on a press record under Estimate Setup → Print Machines → Sheet-Fed Offset in GelatoConnect Estimator. Digital, web, and large-format presses have their own field guides. Finishing equipment, pricing-rule adjustments, and machine-tag definitions are covered in their own clusters.
Identification
Field | What it controls | When to change this | What depends on it |
Name | The display name Estimator shows on the Print Machines list, on every quote's route information, and in the Excluded machines section of Issue analysis. | When the press is renamed in your shop or when the current name does not match the physical label. | The press name on every quote breakdown and the Excluded machines entry; routing math is unaffected. |
Manufacturer | Free-text label captured alongside the name (e.g., Heidelberg, KBA, Komori). | When you transfer a record between brands or correct a typo. | Display only; no effect on routing or pricing. |
Machine Type | Locked at Sheet-Fed Offset for this guide. Switching to another machine type rewrites the editor and drops offset-specific values; treat as a re-create. | Only when first creating the record. | Every cost calculation on every quote that uses this press. |
Status (Active / Inactive) | Whether the press is a candidate when Estimator routes a quote. | When the press is taken out of service, decommissioned, or temporarily mothballed. | Routing on every new and recalculated quote. Inactive presses are dropped before the candidate filter runs and never appear under Excluded machines. |
Tags | Compatibility labels linking the press to substrates, finishing machines, and product categories. | When you add a new substrate group, retire an old one, or onboard new finishing equipment that this press feeds. | Routing on every quote: a quote that requires a tag the press lacks is excluded with the reason "no machine matches tags". |
Physical capabilities
Field | What it controls | When to change this | What depends on it |
Minimum sheet size (width × height) | The smallest flat sheet the gripper can pick up, in millimetres or inches. | When the press's gripper specification changes, or when calibration shows the practical minimum differs from the spec sheet. | Routing for every short-edge or odd-size job. Excluded machines lists "sheet smaller than minimum" when a quote falls below the limit. |
Maximum sheet size (width × height) | The largest flat sheet the cylinders can pass. | When you commission a new feeder or measure a hard limit that differs from spec. | Routing for every B1, B2, or large-sheet quote. Excluded machines entry "sheet larger than maximum" fires when exceeded. |
Maximum stock caliper | The thickest paper or board the press can run without jamming, in microns or points. | When a different feeder is fitted, or when run experience shows the practical limit differs from spec. | Routing for board, cover, and packaging jobs. Excluded machines entry "caliper exceeds maximum" fires when a quote uses a substrate above this value. |
Non-printable margins (width / height) | Edge area the gripper and printable cylinder cannot reach. | When you change cylinder dressing or replace the gripper bar. | The imposition the planning engine produces — if the bleed and trim margins do not fit within the printable area, the press is excluded. |
Operational speeds and labour
Field | What it controls | When to change this | What depends on it |
Make-ready hours | Fixed overhead time before the run starts: load paper, mount plates, run colour bars. | When the press's actual make-ready differs from the default by ≥0.1 hour (measured from the operator log). | The Make-ready line on every quote using this press. |
Make-ready (sheets) | Sheets consumed during ink registration before the press prints saleable copies. | When commissioning measurements show waste differs from the spec sheet, or when a new paper supplier shifts the waste profile. | The substrate quantity on every offset quote, and therefore the substrate cost line. |
Output per hour | Maximum sustained production speed at standard quality, in sides per hour. | When commissioning measurements (or annual recalibration) show the speed differs from the default. | The Run-time line on every quote: run minutes = sides ÷ output per hour. |
Machine rate per hour | Hourly running cost of the press (amortisation, electricity, consumables), in tenant currency. | When you re-cost the press (e.g., after a service contract change) or move from straight-line to actual-use amortisation. | The machine portion of the Make-ready and run lines on every quote using this press. |
Operator labour rate per hour | Hourly cost of the press operator. | When operator wages change or when you switch the cost-allocation model. | The labour portion of Make-ready and run lines. |
Over copies | Extra sheets produced beyond the ordered quantity to cover finishing losses. | When the downstream cutter, folder, or stitcher consistently loses more or fewer copies than the default. | The substrate quantity and the finishing handoff count on every quote. |
Running spoils % | Extra sheets spoiled during the run, as a percentage of the necessary quantity. | When run experience shows a different waste profile (paper change, ink change, climate change). | The substrate quantity on every quote. |
Offset-specific cost fields
Field | What it controls | When to change this | What depends on it |
Plate cost | All-in cost of one plate (material, chemicals, CTP processing). | When your plate supplier changes price, or when you switch plate-making process. | The fixed-cost portion of every offset run. Plate count = colours × parts × surfaces. |
Plate-making labour per hour | Hourly cost of the operator who mounts and processes plates. | When prepress wages change or when you reassign the work to a different team. | The plate-making line on every offset quote. |
Processor plates per minute | Throughput of the plate processor, in plates per minute. | When you replace the processor or measure a different throughput. | The plate-making labour minutes on every offset quote: plates ÷ processor rate. |
Make-ready material cost | Fixed material cost added to the make-ready line beyond the sheet count (e.g., chemistry, blanket wash). | When chemistry or consumable contracts change. | The make-ready cost line on every offset quote. |
Spot-colour make-ready fixed | Fixed labour cost added per spot colour beyond CMYK. | When the wash-up and changeover procedure for spot colours changes. | The make-ready labour line on offset quotes that include Pantone or other spot inks. |
Paper-coat extra price | Per-coating adder applied to the paper bucket (e.g., Uncoated:30; Silk:61; Gloss:50). | When the press's behaviour on different coatings changes, or when you onboard a new coating. | The paper cost line on every offset quote, scaled by the configured coating amount. |
Color units | Number of ink units the press carries (e.g., 2, 4, 5, 8). | When you add or remove an ink unit. | The maximum number of process+spot colours the press can image in one pass before requiring a second pass. |
Impose files price | Per-file imposition charge added to the prepress bucket. | When your prepress workflow changes its per-file cost. | The prepress line on every offset quote. |
Preflight check price per page | Per-page preflight cost added to the prepress bucket. | When your preflight tooling or contract changes. | The prepress line on every offset quote. |
Print method | Imposition strategies the press supports (e.g., Work and Turn). | When you change cylinder dressing or add a new imposition workflow. | The imposition the planning engine produces; only methods in this list are considered. |
Run-speed overrides (card view)
Field | What it controls | When to change this | What depends on it |
Run-speed override table | Per-substrate or per-weight overrides on the default Output per hour. | When a specific paper, weight, or coating consistently runs slower or faster than the default and you want Estimator to model that. | The run-time line on quotes that match the override row; the default speed applies otherwise. |
Volume markup tiers (card view)
Field | What it controls | When to change this | What depends on it |
Volume markup tiers | Quantity-banded markup applied to the press's machine line on top of cost. | When you want to taper your offset margin by run size (e.g., higher markup on short runs). | The machine bucket on quotes that match a tier band. |
Things to know
Switching Machine Type away from Sheet-Fed Offset rewrites the editor and discards the plate-cost, wash-up, and coating fields. Treat a change of type as a re-create.
Plate cost is multiplied by colours × parts × surfaces. A 4/4 job on a single section needs 8 plates, so doubling the plate cost doubles the plate line.
Make-ready waste sheets is independent of run quantity — it is a fixed setup loss. Long runs absorb this cost; short runs are penalised proportionally.
The Tags field is the primary mechanism for restricting a substrate or a finishing path to specific presses. Leave it empty only when the press should be considered for any substrate-finishing combination.
