Artwork Guide

Artwork Guide

Whether you are new to print design or just want to double-check you are doing things correctly, this guide outlines the key considerations when supplying artwork, helping you avoid delays or unexpected results.

Creating your artwork

Start by creating a new document using your preferred design software or online design tool. This can be anything from a simple browser-based editor to professional design software.

  • • Online tools: Canva and similar browser-based designers
  • • Adobe Creative Suite: Photoshop, Illustrator, InDesign
  • • CorelDRAW: Bitmap and vector design support
  • • Microsoft Office: Word, Publisher or PowerPoint
  • • Other software: Any tool that can export a high-quality PDF
  1. • Set your document to the correct finished size.
  2. • Keep important text and logos inside a safe area.
  3. • Add images, text and colours to build your design.
  4. • Export your final artwork as a PDF.

Print & colour guidelines

  • • Keep text and important elements at least 3mm from the edge
  • • Extend background colours and images fully to the edge of the page
  • • Avoid borders where possible, trimming tolerances can make them appear uneven
  • • Use images at 300 DPI for sharp, professional print quality
  • • Supply artwork as single-page PDFs

Colours on screen often appear brighter than in print because screens use RGB colour made from LED light, while printing uses CMYK inks applied to paper. This difference means some colour variation is normal when moving from screen to print.

Our proofing system automatically converts your artwork to CMYK and shows you exactly how it will print before approval.

For solid black areas, we recommend using a rich black mix:
C 60% / M 60% / Y 0% / K 100%

Before you approve

  • • Check spelling, grammar, prices and dates
  • • Review yellow tones carefully after upload
  • • Ensure no important content sits close to the edge
  • • Only approve when you are completely happy

Uploading your artwork

After placing your order and completing payment, you will be taken to our file upload page. This is where you upload, preview and approve your artwork before it goes to print.

Step 1 - Choose your product

Select the product you have ordered. If your order contains multiple items, start with the first product listed.

Step 2 - Design service (if purchased)

If you have paid for our professional design service, select this option to complete a short design brief. A proof will be emailed to you within 3-4 working days.

Step 3 - Upload your file

Choose the correct size and orientation, then upload your artwork file. For double-sided products, upload each side separately, or upload a two-page PDF containing both sides.

Step 4 - Preview and adjust

You will see a live preview of your artwork. Your design should reach the black edge line. If needed, use the crop and resize tools to make your artwork fill the page.

Step 5 - Final check and approval

Carefully review the final preview, what you see on screen is exactly what will be printed. Enter your invoice number and product code, then click Approve & Print.

Once approved, your file enters our automated production workflow and no changes can be made.
