Screenprinted waterslide decals for porcelain onglaze decoration

1. Scope and Applicability

This method covers unapplied ceramic waterslide decal sheets for fired onglaze decoration of glazed hard porcelain only: purchased unprinted gummed carrier paper, a single black ready-mixed ceramic screen ink, a separately printed clear burn-out covercoat, electrically powered drying, trimming, QC and dispatch. It requires actual supplier qualification of the ink/gum/film system on the declared porcelain glaze and firing schedule. The producer original establishes real screen exposure, screen printing and tunnel drying; it does not establish its supplier recipe, heat source or this site’s quantitative inputs. This selected electric/no-on-site-combustion route must be verified from heater nameplates, operating records and matched meters before application. It is a conditional method variant, not a measured inventory of the cited maker. Its selected CN electricity interface cannot represent that German maker’s actual electricity supply. [mr-screen-production; tullis-waterslide; vibrantz-ceramic]

Pressure-sensitive paper labels retain the paper face on the receiving article; this decal instead releases an ink/covercoat film from its temporary paper by water-softening the gum. The ink layer and transfer film have distinct supplied masses, retained solids and solvent releases. Offset books and loose image sheets retain their paper/ink structure and do not implement this release/film route. A calendar’s content alone is not a new manufacturing identity. This method excludes every calendar structure, PSA labels, heat/dry-peel transfer, non-fired organic/model decals, glass/enamel/plastic/metal receiving surfaces, bone china/stoneware, underglaze/inglaze and precious-metal decoration, digital/offset/UV routes, onsite paper/gum/ink manufacture, gas/steam drying and onsite combustion or effluent treatment. Additional chemistry or on-site emissions-control treatment requires explicit method extension. No source formulation, retention, drying time or historical quantity is a default.

4. Measurement and Unit Rules

rule_id	Applies to	Required property	Required unit	Rule
reference_mass	reference product	Mass	kg	Q is total calibrated net accepted dry sheet mass in the same period, including carrier/gum/image/film and measured residual water and solvent at the accepted supplied state, excluding packing/reject/test sheets. No per-sheet mass is fixed.
common_basis	reference denominator for all inventory rows	Mass	kg	Mass/kg applies to the common reference denominator Q only. Each numerator retains its own native property/unit: electricity is Net calorific value/MJ, not Mass/kg. Normalize every exchange and protocol to the same accepted output Q; zero/missing Q blocks normalization.
layer_mass	decal_paper, ceramic_ink, covercoat, finished	Mass	kg	Keep dry carrier, release-gum solids, ink solids, retained dry film and residual water separately. Purchased coated paper is one input: component disclosure cannot create duplicate paper/gum exchanges or backgrounds.
wet_supply	ceramic_ink, covercoat, emulsion, thinner, cleaner	Mass	kg	Supplied formulations use actual wet mass. Reconcile whole supplied mass into measured H2O, each organic/inorganic non-water liquid, actual measured nonvolatile solids and any other retained components. Non-water mass is not a solids measurement. Constituent mass uses actual lot composition; measured solids/retention reconcile every component to waste, stock, product and air. No source recipe becomes a default.
electric_basis	electricity	Net calorific value 93a60a56-a3c8-11da-a746-0800200c9a66	MJ	The selected electricity flow property is named Net calorific value, not a heating-value assumption about electric power. Record measured kWh and exact 3.6 MJ/kWh conversion; match the native CN grid-average consumption mix delivered at user-side 1–35 kV, actual region/year and provider. Producer machinery evidence does not establish this supply.
water_mass	water, washwater	Mass	kg	For volume records use measured density at recorded temperature and composition. Database secondary mass coefficients are not density; record wastewater solids and wet basis.
particle_basis	pm_fine, pm_coarse, pm_large, collected_dust	Mass	kg	Separate emitted disjoint fractions ≤2.5, >2.5–10 and >10 micrometres from collected dust. PM10 and total particulate sums are QA only, not additional exchanges.

5. System Boundary

Boundary Abstraction

Field	Value
declared_starting_condition	Received qualified unprinted gummed ceramic transfer paper, premixed black ceramic paste, lacquer and actual screen-preparation supplies
starting_condition_role	Foreground converting start, not the lifecycle start
product_classification_scope	Only the porcelain-onglaze decal subset of CPC32630; no calendar coverage
recursive_input_rule	Do not feed a generic finished decal back as virgin input. Trace actual externally supplied intermediates once; internal rework is an internal link, not purchased product
upstream_dataset_requirement	Require actual supplier-to-site transport coverage without duplication and supplier-compatible pulp/base-paper manufacture, gum/coating, ceramic pigment/flux/paste, lacquer/solvents, mesh/emulsion and utility/packaging backgrounds. Missing upstream processes make cradle-to-gate LCI incomplete
disclosure	Record supplier versus integrated production and every actual handoff. Application water/paper removal/porcelain firing are downstream, not hidden manufacturing omissions

rule_id	Applies to	Rule	source_ids
boundary_gate	foreground	Include screen preparation, make-ready, ink and covercoat printing, electric drying/ventilation, actual cleaning, trim/QC losses and dispatch. Aggregate them into one foreground unit while metering each stage separately; physical internal handoffs have equal incoming/outgoing masses.	mr-screen-production
upstream_paper	upstream	Use JRC pulp/paper processes only for the actual supplier route, including actual coating. Wood-sawmill, plywood or conifer surveys cannot substitute. No generic mill recipe, cutting factor or broke-recycling assumption is imported.	jrc-paper-bref-2015
downstream_transfer	application	The paper carrier is delivered, then removed during downstream water release; track gum partition, film/ink transfer, spent paper, application water and kiln burnout/firing in any downstream model. No fired-ware or decoration-lifetime claim is made by the gate inventory.	tullis-waterslide; vibrantz-ceramic

7. Allocation and Co-product Handling

rule_id	Applies to	Rule	source_ids
allocation_separate	foreground	First investigate process subdivision and feasible system expansion to avoid allocation; meter actual campaigns/stages and directly attributable shared utilities. If neither is feasible, justify a relevant causal physical relationship; another relationship, including economic allocation, requires documented reasons for rejecting prior steps and matched output/value records. Expanded-system results cover the added functions explicitly. This uses the hierarchy in PEF Annex I Section 4.5 only and does not claim full PEF conformity or adopt a recycling formula. Physical product, stock, waste, water and carbon balances retain actual quantities before any environmental burden allocation; never multiply co-product physical output by allocation share.	pef-allocation
allocation_waste	waste	No co-product or substitution credit is assumed for contaminated paper, spent solvent or ink. If actual marketable recovery exists, independently establish quality, receiver and method, report pre-allocation physical balances and post-allocation burden ledger separately. Internal returns are counted once and treatment receiver burdens are linked explicitly.

8. Foreground Data Collection, Calculation, and Quality Rules

Layer Accounting

component_id	Physical layer	Quantity and fate
carrier	Temporary cellulose-paper carrier	Supplier base-sheet dry mass and actual moisture, present at gate, later removed; never a directly applied label face
release	Water-softenable gum release layer	Actual supplier coat composition/mass on the purchased paper; require lot specification or validated differential weighing, disclose uncertainty and test loss; no guessed starch/PVA recipe
image	Black ceramic ink image	Wet paste input separates actual pigment/flux solids, medium and solvents; retained image solids distinct from transfer film
film	Clear organic covercoat transfer film	Wet lacquer input, dried retained film and air/waste solvent outputs separately; downstream burnout is not a permanent polymer decoration

Data Collection Protocols

cp_water	decal_converting	water, washwater	foreground_record	purchased and returned water; density/temperature; washwater mass/volume; solids; receiver; residual water	Meter supply and segregated discharge, characterize washwater and measure retained/evaporated water; internal recirculation is not another withdrawal	kg	Each lot and matched reporting period	Complete matched period, including setup and rejects	Actual site and supplier lots	per 1 kg reference flow	Calibration, batch/SDS/provider records, acceptance and uncertainty
cp_packing	decal_converting	packing	foreground_record	interleaf/carton/PE grade; receipt; shipped mass; stock; offcuts; tare; reusable shares	Weigh actual individual packing components; match input and shipped output and stocks, exclude from Q	kg	Each lot and matched reporting period	Complete matched period, including setup and rejects	Actual site and supplier lots	per 1 kg reference flow	Calibration, batch/SDS/provider records, acceptance and uncertainty
cp_waste	decal_converting	wastes	foreground_record	separate stream mass; composition; solvent/water/solids; collected dust sizes; receiver; manifests	Calibrated segregated bins and waste transfer records; avoid double counting solids in water, solvent in rags, internal reuse and emitted dust	kg	Each lot and matched reporting period	Complete matched period, including setup and rejects	Actual site and supplier lots	per 1 kg reference flow	Calibration, batch/SDS/provider records, acceptance and uncertainty

Survey all formulation constituents; new actual release species require separate verified cards	kg	Each lot and matched reporting period	Complete matched period, including setup and rejects	Actual site and supplier lots	per 1 kg reference flow	Calibration, batch/SDS/provider records, acceptance and uncertainty

Calculation Rules

rule_id	Applies to	Formula or rule	Inputs	Output	source_ids
period_basis	all inventory rows	For each row i, divide its measured period exchange A_i by accepted net output Q; a_i = A_i / Q. Keep the numerator unit and disclose stock/changeover reconciliation.	A_i; Q; cp_output	Amount per 1 kg reference flow
layer_reconcile	decal_paper, ceramic_ink, covercoat, finished	Accepted sheet mass is retained dry carrier + dry gum + retained image solids + retained covercoat-film solids + actual residual water/solvent. For purchased composite paper, its component sum reconciles to one receipt; no constituent double counting.	cp_layers; cp_output	Disclosed physical layer balance	tullis-waterslide; vibrantz-ceramic
solvent_balance	butyl_air, ethyl_air	For each actual species, net release is species input minus product retention, net stock accumulation, solvent sent out in each waste and documented recovered export. Internal solvent recovery is a loop, not destruction. Reconcile monitored vent and fugitive components without subtracting recovery twice or adding total VOC again. A negative/unclosed balance requires investigation, never clamping to zero.	cp_materials; cp_layers; cp_waste; cp_air	Species-specific net kg release	epa-eiip-2002
wet_stream_balance	wet formulations and waste outputs	For each separately collected liquid stream, use whole wet mass or V multiplied by its measured density at the recorded state. Keep H2O, non-water liquids, actual solids and contaminants as internal composition ledgers whose sum equals that one whole stream; never send its solids or solvent out again unless physically separated and independently measured. Semisolid paste, separated solids, captured dust and contaminated cloth require their actual phase and receiver; “wet” alone does not establish liquid identity. Track issues/unused returns, beginning/end raw-material and work-in-progress stocks, test loss and internal rework once.	cp_layers; cp_materials; cp_water; cp_waste	Reconciled whole-stream and component accounts with residual uncertainty	epa-eiip-2002
packing_reconcile	interleaf, carton, pe_wrap and their shipped outputs	For each actual component reconcile beginning stock plus receipts against end stock, shipped packing, unused supplier returns, recorded offcuts/damage and other actual losses. Shipped tare is outside Q. Screen inbound supplier containers, pallets, tape and other actual packing separately; identify each additional exchange and compatible receiver instead of hiding it in the sheet or imposing a generic packing rate.	cp_packing; cp_materials; cp_waste	Full individual packing/input-stock-output account

Data Quality Requirements

requirement_id	Applies to	Requirement	Evidence
physical_balances	all inventory rows	Retain pre-allocation paper/solids, water and fossil/biogenic carbon balances, supplier backgrounds, actual losses and stock changes with uncertainty. Carbon in paper/gum/film is not an invented direct CO2 emission; actual biogenic CO2, if an expanded route emits it, must never be removed because of greenhouse-gas reporting conventions.	cp_layers; cp_water; cp_waste; cp_air
identity_provider	all inventory rows	Verified broad identities require actual compatible material/route qualifiers and independent provider quantity/background checks. Missing UUIDs or unresolved chemical composition/receiving medium remain explicit gaps before concrete dataset release. Survey every actual extra chemical, waste or release; this conditional inventory is not a fixed factory recipe.	cp_materials; cp_air
actual_consumables	screen preparation, press, drying, cleaning and controls	Screen actual frame/replacement parts, squeegees, sensitizers, reclaimers, antiblocking additions, oils/greases, filters and other maintenance/control consumables and their spent streams. A supplier-emulsion formulation is one receipt; separately purchased auxiliaries are separate exchanges. Retain reusable life/stock allocation and actual setup/replacement records; add each actual material, chemical, waste and elementary release as an atomic card before claiming complete LCI. No positive generic consumption is invented. If onsite abatement is present, measure its inputs, captured streams and actual species transformations in an explicit process extension; captured VOC is not automatically destroyed and exhaust after capture is the gate emission.	cp_materials; cp_energy; cp_water; cp_waste; cp_air
source_scope	all source rules	Manufacturer statements support the corresponding layer/operation only. Do not claim one maker uses another supplier’s grade. EPA supports solvent accounting, JRC supports actual upstream paper and qualitative cutting screening; no historical factor or single-site amount is generalized.	mr-screen-production; tullis-waterslide; vibrantz-ceramic; epa-eiip-2002; jrc-paper-bref-2015

9. Validation Rules

rule_id	Applies to	Rule	source_ids
validate_scope	dataset	Reject incompatible receiver/process routes, direct PSA labeling and every calendar. Require actual hard-porcelain glaze/firing compatibility; food-contact suitability requires separate actual migration/compliance evidence and is not established by this PCR.	mr-screen-production
validate_basis	all inventory rows	Require exactly one finished reference output, 1 kg basis in both languages and all protocols; preserve carrier/gum/ink/film and exclude packing from Q. Missing Q or unresolved reference identity blocks normalization.
validate_releases	elementary and waste outputs	Require exact chemical/CAS, actual receiving compartment and reference property/unit; reject correction flows, near-name species, double-counted cumulative PM or VOC, and direct-water UUIDs for external treatment. Keep collected dust separate. Actual additional species require their own identity/measurement audit.	epa-eiip-2002; jrc-paper-bref-2015
validate_coverage	dataset	Report measured versus estimated/missing quantities, performed/skipped checks, unresolved UUIDs/provider bases and completeness. Authored method status does not prove a complete plant dataset or independent scientific approval.

10. Published Dataset Profile

Field	Value
dataset_role	Foreground decal converting process with explicit supplier background links
downstream_use	secondary_dataset; background_dataset
allowed_use	Physically qualified gate production of these unapplied porcelain-onglaze decal sheets; link actual use/firing separately
excluded_use	Calendar/label/full porcelain manufacture; incompatible receiver or transfer route; lifetime/food-contact claims without actual evidence
required_metadata	All reference qualifiers, per-row units and supply/receipt/receiver identity, boundaries, raw collection period and allocation
required_quality_disclosure	Layer/physical balances, measured/calculated gaps, UUID/provider compatibility debts, loss/stock/uncertainty and independent review state
update_trigger	Change of paper/gum, ink/film formulation, receiver glaze/firing compatibility, heating/controls, suppliers, emission identities or measurement basis
