Keep all important artwork inside the green border (such as text & logos). Make sure the background covers the whole template (including the areas outside the green border).
Use CMYK colours.
If you are having difficulty or not sure how to set up a template, send an email to support@custom flags.co.uk with your artwork plus the product and size you will be purchasing. We will then set up a proof free of charge which you can upload when placing the order. NB proofs will be low resolution and for upload purposes only - we will set up the artwork in high resolution and use this for print.
If you have any questions or queries give us a call on 01246 297600 and our friendly staff will be more than happy to help.
