It is important to print the pages yourself if any of the following apply.
1. If colours/shading, etc of the printing is critical.
2. If you want special paper - for example a tinted paper rather than a plain white paper.
3. If your volume is a non-standard size or shape (i.e. If you are printing on anything other than standard A4 portrait paper).
We have, at this stage, only made arrangements for standard printing. Though the copycentre can cope with A3s and folding, too. If you are making an 'odd sized' book, it is important that you read our section on paper grain - see Preparing a thesis for binding.
Also note that we can trim pages down to size if you are printing on a larger size than you actually want to bind, as we have huge guillotines.
4. If for any reason you have concerns about the printing result.
5. If there is a VERY limited binding timeframe.
