Yes, we most definitely do! We have printed a lot of digital artwork over the years, and it is becoming more and more popular. In a nutshell, if you've created it (i.e. you own the copyright to it), we can print it.
There are a few things to be aware of when you're printing an artwork that has been created digitally. The most important thing is that when you're creating an artwork, you start out with a canvas/artboard with enough size and resolution to produce a high quality print.
Always make sure your canvas/artboard is sized to the maximum print size you'd like to offer, and also set to the highest resolution that your program of choice offers.
For example, if you'd like to be able to print the artwork up to A2 in size, make sure that your canvas settings are A2 (420x594mm) at 300dpi. You could also set your canvas size to A4 size at 600dpi - this will also allow you to print up to A2 size (when resized to A2 dimensions, the resolution will interpolate to 300dpi).
This will allow you to create smaller prints as well, but most importantly will ensure that your artwork will print beautifully at A2 size
When you're exporting your files, please save them as either TIFF, JPEG or PNG.
