A file is print-ready only for a defined printer, product, size, material, and finishing plan. The designer can prepare and inspect the artwork, but the receiving printer's current specification controls the final handoff.
Begin with approved content and production facts. If dimensions, dielines, copy, barcodes, finishes, or quantities are still changing, label the artwork as a review proof rather than a release file.
Ask the printer for the specification first
Collect the receiving requirements before final layout. Depending on the job, the printer may specify page or panel size, bleed, safe area, color mode, color profile, spot colors, image resolution, ink limits, dieline construction, overprint behavior, PDF standard, marks, font treatment, naming, and transfer method.
Do not copy settings from an unrelated past project. A brochure printed on sheets and a flexible package produced from a dieline can have different constraints. Record the printer contact and the date of the specification used.
Freeze copy and artwork versions
Create a release checklist with every text block and regulated or client-controlled element that requires approval. For packaging or labels, that may include product name, net contents, ingredients or technical copy supplied by the client, addresses, codes, symbols, warnings, and language versions. The client or its qualified reviewer owns the accuracy and approval of that content.
Use one source of truth for copy. Pasting revisions from several email threads invites mismatch. Record who approved the release version and when. If an urgent correction follows approval, increment the version and repeat the affected checks.
Link every placed image or illustration to its approved source. Check that the file is available, has adequate quality for the planned size, and carries the correct usage permission. Remove hidden alternates that could confuse the output package.
Treat dielines as controlled production assets
A dieline should come from the printer or an authorized packaging source whenever possible. Confirm its scale, units, panel names, cut lines, folds, glue areas, perforations, safe areas, and required nonprinting layers.
Keep production guides separate from printable artwork according to the printer's instructions. Do not redraw or resize a dieline because it looks close to a previous package. Even a small structural change can affect alignment across panels.
For a family of sizes or flavors, maintain a version matrix. It should show which dieline, copy set, barcode or identifier, artwork, and approval belong together. That is more reliable than assuming the newest file in a folder contains every current element.
Check type, images, and color deliberately
Review fonts, missing glyphs, line breaks, small text, reversed text, and any outlined type. Keep an editable source file even if the printer asks for outlined output. Outlining can protect appearance in one handoff, but it also makes later copy correction harder.
Inspect effective image resolution at final placed size. Check crop, transparency, color conversion, and sharpening in the production context. A source image can be large yet unsuitable after a severe crop.
Confirm process and spot colors with the printer. A screen preview cannot guarantee how ink, substrate, coating, and finishing will appear. When color is critical, define the physical proof or approved reference used for the decision.
Export with the agreed PDF settings
Adobe documents PDF creation in Illustrator and notes that PDF settings affect the resulting file. Adobe also provides an InDesign workflow for producing print-ready PDF files. Use the printer's requested preset or standard rather than choosing a setting because its name sounds suitable.
Confirm whether the PDF should include bleed, printer's marks, a specific output intent, live transparency, flattened output, layers, or editable Illustrator data. Keeping extra editability can enlarge the file or expose content the printer does not need. Removing it can limit later changes. Follow the actual handoff requirement.
Preflight the package
A focused preflight checks:
- final dimensions and orientation against the purchase specification;
- bleed and safe-area treatment on every relevant edge or panel;
- current approved copy, codes, and artwork variants;
- linked image availability and effective quality;
- font status and text overflow;
- color spaces, spot-color names, overprint, and transparency;
- dieline and nonprinting-layer handling; and
- PDF settings, filename, version, and output location.
Open the exported PDF independently. Review every page or panel at useful magnification. Compare totals such as page count, language count, or variant count with the release matrix.
Send review evidence with the files
The handoff should include the production PDF, the printer specification used, a low-resolution visual reference where useful, the source package if contracted, and a release note listing version, size, color setup, special finishes, unresolved items, and approving parties.
Brownsofts' Print-Ready File Preparation service supports this production step. The release should still say that final print acceptance belongs to the receiving printer and the client's authorized approver.
Keep the delivered package unchanged after release. If the printer requests a correction, issue a new version and preserve the reason. That record helps everyone identify exactly what was approved and what changed before production.
