Preparing artwork for large format digital print

When preparing artwork for large format print there are many 'Do's & Dont's' and potential pitfalls that can be easily avoided.

Below is a brief list of the main things to look out for and if anyone out there has anything to add or you'd like to discuss any areas in more detail please don't hesitate to post a comment.

File Formats
The most universally accepted file format is .pdf. Make sure that your .pdf settings are set to high quality with images at 300dpi and, coupled with the other key elements mentioned in this blog, you can't go wrong. Other widely accepted formats include .eps, .jpeg and .tif.

Files in their native format such as .psd , .ai and .indd are acceptable but please pay close attention to converting fonts and effects when supplying in these formats.

File Size
When supplying your finished artwork it's always best to supply them at full size if possible but if the file size is too large a minimum of 1:4 scale is required, making sure that all images contained are a minimum of 300dpi. Large files aren't a problem here at  The Display Store as we have a large file upload service for your convenience hosted by Yousendit.

Colour Mode
Always set your document to CMYK mode when designing or at least convert to this mode before sending to print. Never supply artwork as RGB or Pantone® colours, this will give unpredictable print results.

Fonts
Text included in your artwork should always be converted to outlines/curves prior to supplying for print. If the printer does not own a copy of the font used in your design there's a good chance that the font could be changed to an alternative style, rendering all your hard work and time spent laying out text worthless.

Transparent Effects
Many design programs now support transparent effects which allow designers to create stunning graphic designs. When it comes to the printing stage however these effects can sometimes be lost in translation and give undesired results. Always flatten transparencies before supplying artwork, that way you can see the end result of the effect and adjust if necessary.

Images
All images contained in your design should be a minimum of 300dpi and in CMYK mode. This is especially important if supplying your artwork at less than full scale.

Make sure that images used are either your own or you have the appropriate license/permission to use them. Often the best way of ensuring this is to buy the rights to use an image from online stock photography services such as istockphoto , getty images , shutterstock or other similar suppliers, this way you can rest assured that no one can accuse you of 'borrowing' their images

Well, that's just a few of the main areas to look out for but watch this space for more detailed blogs on individual areas in the near future. Don't forget... if you'd like to discuss any part of the above in more detail i am more than happy to do so.
