Start With the Right Artwork Version
Send the final approved version only. If a file is still being changed after approval, it can lead to mismatched text, cropped images or a plate that does not match the printed sample. Keep one clear version as the master and make sure everyone involved is working from the same copy.
For flexo photopolymer plate-making, the artwork should be supplied in a print-ready state with linked images intact and fonts either embedded or converted where needed. If you are sending a last-minute update, say exactly what has changed so the prepress team can check those areas first.
- Use the latest approved artwork only
- Remove duplicate file versions from the upload set
- Flag any changes made after client sign-off
- Keep a copy of the original artwork and the final print file
Check Colours, Bleeds and Overprints
Flexo work needs careful attention to colour setup because labels and packaging often run on different stocks and press conditions. Check that your colours are set correctly, especially spot colours, dark text, reverse text and solids that must hold on press. If your job includes varnish or special layers, label those clearly in the file.
Bleed is just as important. Leave enough bleed on all sides so trimming does not leave a white edge. For small labels, even a tiny shift can show. Keep fine text away from trim lines and avoid placing important detail too close to the edge.
- Confirm CMYK or spot colour setup before sending
- Allow bleed on every trimmed side
- Avoid thin coloured rules near the cut line
- Mark varnish, knockout and special areas clearly
Set Up Type and Linework for Plate Output
Text and linework need enough strength to reproduce well on photopolymer plates. Very small type, hairline rules and weak reverse text can break up or fill in when printed. This matters more on corrugated, film and textured stock, where the print surface may be less forgiving.
Before sending, check that all fonts are embedded or outlined, and that any vector artwork stays sharp at the correct size. If your design uses a lot of fine detail, ask for technical job advice before the final file goes out. A small adjustment now can prevent wasted material later on.
- Outline or embed all fonts
- Avoid hairline strokes and ultra small text
- Check reverse text on dark backgrounds
- Review fine detail at actual print size
Send Proofs That Match the Press Intent
Proofs help the plate team compare what is on screen with what needs to be made for press. If you have a contract proof, soft proof or previous printed sample, send it with the job so any differences can be picked up before plate production starts. This is especially helpful when the same artwork is being reused on a new substrate or a different press setup.
When there are layout changes, circle them or list them in plain language. Do not assume the changes are obvious. A short note can save a lot of back-and-forth and helps the team compare artwork, imposition and screening decisions more accurately.
- Include the latest approved proof
- Attach any printed sample for comparison
- List changes clearly in your job note
- Show which version is the final one for plate-making
Prepare Files for Imposition and Press Direction
Labels and packaging often need imposition planning before plates are made. Send details about repeat size, web direction, crease lines, cut lines and any special layout requirements. If the job will be mounted in a particular orientation, say so early. This helps the plate team plan the job correctly and avoid unwanted rotation or layout issues.
If you are unsure what to send, include the dieline or layout template and ask for checking. Our Midrand team handles artwork preflight, imposition planning and file checking for printers across Johannesburg, Pretoria, Durban, Cape Town and Gqeberha, as well as the East Rand and West Rand.
- Include dielines or cutter guides where relevant
- State repeat size and press direction
- Flag crease, fold and cut positions
- Note any rotation or mounting requirements
Use a Practical Job Note for Plate-Making
A clear job note makes the whole process easier. Include the stock type, label or packaging format, quantity of plates if known, and any special handling needs. If the job is for a coastal area, remember that humidity can affect storage and handling, so it helps to mention if the plates are needed for same-day collection or courier dispatch.
For South African printers, load-shedding planning can also matter. If you need to coordinate around power outages or production windows, say so when you send the job. We can assist with collection coordination, dispatch packing and courier delivery from our Midrand base, with support for local deliveries and national shipping.
- State substrate, format and job quantity
- Add handling notes for humidity or storage
- Mention collection or courier requirements
- Include any timing issues linked to production shifts
Final Preflight Checklist Before Submission
Before you upload or send the job, do a final check on the basics. Confirm that all pages, layers and linked items are present. Make sure the file name is clear and that everyone can identify the job without guessing. This small step cuts down on errors and helps the plate team move faster through prepress and remake support if needed.
Our team in Midrand, Gauteng works with label and packaging printers who want practical plate advice, clear file checks and proper dispatch. Founded in 2007, Flexo Printer Plates supports supply needs across South Africa through enquiry form requests and courier delivery to major centres and surrounding areas.
- Check the final PDF or artwork file opens correctly
- Confirm images, links and fonts are complete
- Use a clear job name and version number
- Send only what is needed for plate-making
