GS1 Sunrise 2027: Getting 2D Barcodes Print-Ready

What Sunrise 2027 actually asks of your artwork

This guide uses Sunrise 2027 as context for planning 2D barcode artwork. The supplied Adobe sources support PDF preparation and output previewing, not GS1 transition scope, dates, accepted symbols or barcode requirements. Obtain current GS1 guidance and your retailer's specifications before selecting symbols or approving artwork. Use the workflow below as a preparation checklist, not as a statement of GS1 compliance.

Treat this as a file preparation and verification project, not just a design change. The encoded data must be valid under your GS1 identification numbers, the symbol must survive the print process, and the printed result must be verified on the real material before you commit to a production run.

• Confirm with your retailer and brand team which symbols will appear on pack after the transition, since a linear code may still be required alongside the 2D symbol during the changeover period
• Record your GS1 identification data, such as the GTIN, in a single source document so the encoded string can be checked character by character before it reaches artwork

Encode and verify the data before it touches the layout

A 2D barcode that scans perfectly but resolves to the wrong product is worse than one that does not scan. Build a data verification step before layout begins. Generate the encoded string from your item record, create the symbol, then decode it with an independent reader and compare the result to the source record.

For a GS1 Digital Link URI, check identifiers and any lot or expiry data against the applicable GS1 syntax specifications and your authorized item records. A transcription error may encode incorrect data, fail validation or prevent resolution even when the symbol can be decoded. Independent decoding and comparison are recommended editorial checks, not substitutes for syntax validation or printed-symbol verification.

• Decode the generated symbol with a phone or dedicated scanner and compare the output string to the source record character by character
• Check that any variable data such as lot or expiry fields uses the correct application identifier format for your market and channel
• Keep the source data file archived with the artwork revision so a future reprint uses the same verified string

Sizing, quiet zone and placement on the dieline

A hypothetical geometry exercise shows how placement decisions interact. All numbers here are invented for the arithmetic. Suppose a symbol plus its quiet zone needs a 26 by 26 millimeter area, consisting of a 22 millimeter symbol with 2 millimeters clear on each side, on a 90 by 60 millimeter carton face. Actual quiet-zone requirements depend on the symbology and module size; these invented dimensions are not a sizing recommendation. The reserved area is 676 square millimeters out of 5400 square millimeters, roughly 12.5 percent. The square fits within the assumed rectangular face, but actual placement still depends on folds, finishes, other artwork and available flat space.

This is an arithmetic estimate for planning only. Establish the permitted symbology, module size, quiet zone, symbol dimensions and any applicable error correction settings from current GS1 and channel specifications, then confirm manufacturability with the converter. Converter approval alone does not establish channel acceptance. As a placement recommendation, keep the symbol and quiet zone away from folds, seams, embossing and potentially interfering finishes.

Note this example is a placement exercise, not a manufacturable dieline, and panel dimensions here are a working assumption for the math, not a claim that flat panel dimensions equal product dimensions.

Color, contrast and substrate considerations

Scanner readability depends on contrast between the symbol and its background. A dark symbol on a light background is the recommended starting point. If brand colors call for a colored symbol, we recommend testing the combination on the actual substrate, because color pairings that look fine to the eye may not scan well.

Work with your converter on how the symbol will be printed. In plated workflows, a single ink is often recommended for small modules. Digital workflows handle named spot colors differently, so confirm how your converter's process will render them. A rich black built from multiple inks can introduce registration variation on small modules, so a single-ink black is commonly preferred. Never use registration black, which prints on every separation, for a barcode. Ask the converter which black they recommend for the symbol. Follow the converter's instructions on marks, layers and proof types rather than applying universal rules.

• Ask the converter to specify the ink or toner combination for the symbol and confirm it on a proof on the actual substrate
• Avoid printing the symbol over varnish, foil or embossing unless the converter has tested it
• Request the quiet zone remain free of any artwork, text or pattern, including background textures

Preflight and file preparation

Deliver the barcode in the converter's agreed print-ready PDF format, preferably retaining vector symbol artwork where supported. If raster artwork is used, agree its resolution at final size with the converter; a high-resolution PDF label alone does not establish barcode quality. Adobe recommends creating print-ready PDFs directly from the source application and documents PDF/X-4 conversion in Acrobat. Adobe's packaging material also describes PDF and PDF/X as recommended exchange formats. Confirm the required PDF standard and export settings with your converter.

Before handoff, use output previewing to check the file. Acrobat's Output Preview can show separations and color warnings, and you can limit the display to specific source color spaces to see, for example, whether any RGB objects remain on the barcode panel. The Ink Manager can remap spot-color inks for previewing. Note that onscreen separation previews do not show trapping, printer marks, halftone screens or resolution; those are verified with the print provider using proofs.

Remember that PDF/X-4 can carry color-managed RGB, so the presence of RGB is not automatically an error. The printer's agreed workflow determines when conversion happens. The goal is that the barcode's final rendering is predictable, which is what you confirm with the converter, not a blanket rule about color spaces.

• Export the converter's agreed PDF format directly from the source application where possible; use PDF/X-4 if requested
• Run output preview separations and color warnings to catch unintended ink coverage on the symbol area
• Confirm with the converter whether the barcode should be a spot plate, a process build or a digital simulation, and set the file up accordingly

Verification and the difference between estimate and test

Every calculation in this guide is planning arithmetic. Printed-piece verification on the real substrate, using the method your channel requires, is how symbol quality is assessed. Even verification does not guarantee scanning in every retail environment. Formal barcode verification assesses symbol quality under controlled conditions. Any required methodology or minimum grade should come from GS1 guidance and your retailer agreements, not from this guide.

Ask your converter whether they perform barcode verification in-house, what grade they report, and whether the report covers the actual production material and ink. If verification is done by a third party, build that into the schedule. Do not assume a symbol that scans on a phone has passed verification; phone scanning is a useful sanity check, not a grade.

Teal does not certify barcode grades or claim retail acceptance; verification is performed by the parties you and your retailer designate.

• Request a verification report on production material, not just on a proof stock
• Confirm the required verification methodology and any minimum grade with your retailer agreement
• Archive the verification report with the job record for reprints and audits

Decision table: where to put verification effort

Use this table to decide where your review effort goes for each artwork revision. It is Teal's editorial planning framework; the sources cited cover only specific underlying principles such as PDF preparation and output previewing.

Practical checklist before you release artwork

Work through this list with each revision. It is a planning framework, not a substitute for the converter's own preflight and your retailer's requirements.

• Encoded string decoded and matched to the source item record character by character
• Symbol dimensions, module size, quiet zone and applicable error correction settings checked against GS1 and channel specifications and confirmed manufacturable by the converter
• Quiet zone clear on all sides and free of texture, text or pattern
• Symbol not crossing folds, seams, embossing, foil or untested varnish
• Ink or toner combination for the symbol agreed with the converter
• PDF exported using the converter's agreed format and settings, using PDF/X-4 if requested
• Output preview separations and color warnings reviewed on the symbol panel
• Printer marks, layers and proof types set per the converter's instructions
• Verification report on production material requested and archived
• Retailer or channel scanning requirements confirmed in your own agreement

Scope limits

This guide covers print preparation workflow only. It does not determine regulatory or retailer compliance, does not set a verification grade threshold, and does not promise any scanning outcome. GS1 syntax rules, your company prefix and any retailer mandates come from your GS1 membership and supply agreements. Teal provides packaging production and editorial guidance; verification, certification and channel acceptance decisions rest with you, your converter and your retailer. Costs, timelines and market conditions are outside this guide's scope.
