Artwork Setup & Pre-Press
Our studio checks and prepares all artwork before printing, ensuring correct bleed, colour profiles and resolution. We fix issues early to avoid delays.

Colour Matching & Proofing
We manage colour accuracy across materials and machines, offering printed proofs where required. Ideal for brand colours, Pantones and sensitive campaigns.

Panel & Layout Preparation
We create accurate panel splits for walls, hoardings and window graphics, ensuring seamless joins and correct scaling. Supplied ready for installation.

File Fixing & Corrections
Send what you have, we can resize, tidy layers, outline fonts and convert any format into a stable, print-ready file. Perfect for urgent or inherited artwork.

Bespoke Print Design Support
Our print designers produce visuals, layouts and full creative assets for signage, graphics, campaigns and branding. Ideal when you need more than file setup.

Quick Turnaround Support
We prioritise urgent projects with fast, efficient studio workflow and clear communication. Perfect for last-minute campaigns, events or reactive jobs.
If you’re unsure which materials or print method are best for your project, our team is here to help. Email sales@wallaceprint.com with your project details, quantities and intended use, and we’ll review everything for you. You’ll receive clear recommendations and a no-obligation quote based on what will deliver the best result.
Artwork Guidelines
Supplying accurate, print-ready artwork ensures your graphics reproduce exactly as intended and move smoothly into production with no delays. These guidelines outline the technical standards required for all large-format print jobs. Following them closely prevents colour shifts, soft imagery, trimming issues and file failures at pre-press.
Following these guidelines ensures a smooth process from submission to print, reflecting your vision with precision and quality. Our studio team is always available for guidance or to clarify any part of the submission process.
Acceptable File Formats
Hi-res PDFs offer the most reliable workflow for large-format printing because they maintain fonts, colours, vector shapes and linked assets in a stable format.
Preferred formats
-
PDF (Hi-res, fonts embedded or outlined) – the most predictable and stable format for print
-
Photoshop: EPS, PDF, PSD, TIFF (flattened where possible)
-
Illustrator: AI, PDF, EPS with fonts outlined & images embedded
-
InDesign: Supply the packaged folder with all fonts and links included
Do:
- Supply PDF/X-1a or PDF/X-4 where possible
- Embed all linked assets
- Ensure fonts are outlined or included
- Keep file names short, clear and descriptive
Don’t: (we may reject and ask to re-supply).
- Send Word, PowerPoint or Canva exports
- Include missing links or unembedded images
- Supply low-resolution PNGs or web graphics
Why this matters:
Non-print formats often alter layout, scale or colour during export. Missing links or layered transparency can cause unexpected results once ripped to print. Stable file formats protect your visual accuracy.
Artwork Preparation
Accurate file preparation prevents alignment issues, trimming mistakes and delays during pre-press. Multi-panel files, cut paths and naming conventions must be clear.
Requirements:
- Name your file clearly using the order reference + size
- For multi-panel projects, submit one full layout with split instructions
- Turn off overprint unless intentionally used
- Define cut lines with a spot colour named “CutContour”
- Keep working files tidy, removing unused layers
Do:
- Provide a visual key or panel diagram for hoardings or wall wraps
- Use spot-colour cut lines (not RGB strokes)
- Consolidate layers into clean, simple groups
Don’t:
- Leave hidden layers, notes, or unused elements
- Flatten cut lines into the artwork
- Use arbitrary file names
Why this matters:
Incorrect file naming, poor layer management or mislabelled cut paths can cause production pauses and increase the risk of finishing errors. Clear preparation ensures accuracy throughout print and finishing.
Colour Specifications
Proper colour setup ensures reliable reproduction. Large-format printers use CMYK output, and spot colours must be clearly defined to avoid colour shift.
Requirements:
- Use Solid Coated Pantone references for spot accuracy
- Maintain original spot colour names
- Supply vector artwork in CMYK
- Supply bitmap images in CMYK or RGB (RGB will convert on RIP)
Do:
- Keep brand colours consistent across documents
- Ensure black elements use the correct CMYK values
- Check gradients for banding at full artwork size
Don’t:
- Rely solely on RGB appearance (screens vary)
- Use mixed colour modes within one layout
- Convert Pantone values manually (retain original naming)
Why this matters:
CMYK and Pantone colours behave differently on various substrates. Incorrect or mixed colour modes cause dull blacks, muddy imagery or unexpected shifts in print. Proper colour management protects brand accuracy.
Bleed Guidelines
Bleed prevents white edging during trimming. Large graphics require more bleed due to substrate movement and installation tolerances.
Requirements:
- Apply 5mm bleed on all edges for every substrate
- Extend backgrounds, colours and imagery fully into bleed
- Keep key content comfortably within safe areas
Do:
- Add bleed before exporting to PDF
- Maintain consistency across multi-panel files
- Check artwork alignment to avoid mis-trim
Don’t:
- Leave backgrounds flush to the document edge
- Place text or logos near trim lines
- Rely on RIP software to add bleed
Why this matters:
Trimming tolerances vary depending on substrate thickness and finishing method. Without adequate bleed, graphics risk showing white edges or misaligned joins.

Frequently asked questions
What file format is best for printing?
PDF is the most reliable format because it maintains fonts, colours and layout. It also reduces the risk of missing links or incompatible files. We accept AI, EPS, TIFF, JPEG and PSD files, but PDF/X-1a or PDF/X-4 typically produces the most predictable results across our printers.
Do I really need bleed on artwork?
Yes. Bleed ensures there are no white edges after trimming. Even a perfectly aligned sheet can shift by a few millimetres during cutting, so bleed protects the final output. As a rule: 5mm for general print, 10–25mm for large-format panels and hoardings
What resolution should images be?
150 dpi at full size is ideal for most large-format prints. For very large outdoor graphics, 100 dpi is normally sufficient because viewing distances are much greater. For small, close-view prints, photographs or signage with fine detail, use 300 dpi where possible.
Can you match Pantone or brand colours?
We can match colours accurately within the limits of CMYK printing and material type. Perfect Pantone matching is not always possible on certain substrates, but we can run test prints if colour accuracy is critical. Please supply colour references where available.
Will RGB files print correctly?
Yes, but colours may shift slightly when converted to CMYK. Bright, neon or highly saturated colours in RGB often appear less vivid in CMYK. If accurate colour reproduction is important, convert artwork to CMYK before sending so you can see how it will print.
Do you check artwork before printing?
Yes. We perform basic pre-press checks for resolution, bleed, fonts and colour setup. If we spot any issues, we’ll contact you before production begins. For complex or high-value jobs, you can request a printed proof.
Can you help prepare artwork for print?
Absolutely. Our studio can correct bleed, resize files, fix colour profiles, outline fonts, tidy layers and convert any format into a print-ready file. If your artwork needs full layout or design changes, we can also provide design services.
How should I supply artwork for multi-panel graphics?
You can supply one complete artwork file, and we’ll split it into panels, or you can provide each panel individually. For wall graphics, hoardings and window displays, supplying a full-size layout often helps ensure perfect alignment. We’ll handle panelisation during pre-press.
